Effects of short term sacral nerve stimulation on anal and rectal function in patients with anal incontinence. (1/1075)

BACKGROUND: Some patients with faecal incontinence are not amenable to simple surgical sphincter repair, due to sphincter weakness in the absence of a structural defect. AIMS: To evaluate the efficacy and possible mode of action of short term stimulation of sacral nerves in patients with faecal incontinence and a structurally intact external anal sphincter. PATIENTS: Twelve patients with faecal incontinence for solid or liquid stool at least once per week. METHODS: A stimulating electrode was placed (percutaneously in 10 patients, operatively in two) into the S3 or S4 foramen. The electrode was left in situ for a minimum of one week with chronic stimulation. RESULTS: Evaluable results were obtained in nine patients, with early electrode displacement in the other three. Incontinence ceased in seven of nine patients and improved notably in one; one patient with previous imperforate anus and sacral agenesis had no symptomatic response. Stimulation seemed to enhance maximum squeeze pressure but did not alter resting pressure. The rectum became less sensitive to distension with no change in rectal compliance. Ambulatory studies showed a possible reduction in rectal contractile activity and diminished episodes of spontaneous anal relaxation. CONCLUSIONS: Short term sacral nerve stimulation notably decreases episodes of faecal incontinence. The effect may be mediated via facilitation of striated sphincter muscle function, and via neuromodulation of sacral reflexes which regulate rectal sensitivity and contractility, and anal motility.  (+info)

Risk factors for abnormal anal cytology in young heterosexual women. (2/1075)

Although anal cancers are up to four times more common in women than men, little is known about the natural history of anal human papillomavirus (HPV) infections and HPV-related anal lesions in women. This study reports on the prevalence of and risks for anal cytological abnormalities over a 1-year period in a cohort of young women participating in a study of the natural history of cervical HPV infection. In addition to their regularly scheduled sexual behavior interviews and cervical testing, consenting women received anal HPV DNA and cytological testing. Anal cytology smears were obtained from 410 women whose mean age was 22.5 +/- 2.5 years at the onset of the study. Sixteen women (3.9%) were found to have abnormal anal cytology: 4 women had low-grade squamous intraepithelial lesions (SILs) or condyloma; and 12 women had atypical cells of undetermined significance. Factors found to be significantly associated with abnormal anal cytology were a history of anal sex [odds ratio (OR), 6.90; 95% confidence interval (CI), 1.7-47.2], a history of cervical SILs (OR, 4.13; 95% CI, 1.3-14.9), and a current anal HPV infection (OR, 12.28; 95% CI, 3.9-43.5). The strong association between anal intercourse and the development of HPV-induced SILs supports the role of sexual transmission of HPV in anal SILs. Young women who had engaged in anal intercourse or had a history of cervical SILs were found to be at highest risk.  (+info)

Faecal composition after surgery for Hirschsprung's disease. (3/1075)

Diarrhoea and perianal excoriation occur frequently after the endorectal pull-through operation for Hirschsprung's disease. A new method of faecal analysis was performed on 3-day stool collections in 17 postoperative Hirschsprung patients and in 14 normal children, in order to define the faecal abnormality and to establish the cause of perianal excoriation in these patients. Loose stools in postoperative patients were deficient in dry solid content and contained an excess of extractable faecal water. This also had a raised electrolyte concentration, particularly with respect to sodium. Total daily output of faecal water was normal. Formed stools from postoperative patients were also deficient in drysolids but had a normal extractable water content. Excess extractable faecal water, the main abnormality of loose stools in these patients, is the result of abnormal water absorption from the distal colon. Perianal excoriation in these patients is most closely associated with the concentration of sodium in faecal water.  (+info)

Investigation and management of long-standing chronic constipation in childhood. (4/1075)

The anorectal physiology of 106 children with long-standing chronic constipation, who had failed to response to a trial of medical treatment, was assessed. 10 (9%) were shown to have ultrashort-segment Hischsprung's disease, later confirmed on histology, The remainder showed evidence of hypertrophy of the internal sphicter on anorectal manometry and had a vigorous anal dilatation (to accept 4 fingers) under general anesthesia. After this, 38% were able to be weaned off all medication and most of the remainder improved. Further anal dilatation and internal sphincterotomy allowed a further 10 children to stop laxative, bringing the total to 48%.  (+info)

Perception of and adaptation to rectal isobaric distension in patients with faecal incontinence. (5/1075)

BACKGROUND: Perception of, and adaptation of the rectum to, distension probably play an important role in the maintenance of continence, but perception studies in faecal incontinence provide controversial conclusions possibly related to methodological biases. In order to better understand perception disorders, the aim of this study was to analyse anorectal adaptation to rectal isobaric distension in subjects with incontinence. PATIENTS/METHODS: Between June 95 and December 97, 97 consecutive patients (nine men and 88 women, mean (SEM) age 55 (1) years) suffering from incontinence were evaluated and compared with 15 healthy volunteers (four men and 11 women, mean age 48 (3) years). The patients were classified into three groups according to their perception status to rectal isobaric distensions (impaired, 22; normal, 61; enhanced, 14). Anal and rectal adaptations to increasing rectal pressure were analysed using a model of rectal isobaric distension. RESULTS: The four groups did not differ with respect to age, parity, or sex ratio. Magnitude of incontinence, prevalence of pelvic disorders, and sphincter defects were similar in the incontinent groups. When compared with healthy controls, anal pressure and rectal adaptation to distension were decreased in incontinent patients. When compared with incontinent patients with normal perception, patients with enhanced perception experienced similar rectal adaptation but had reduced anal pressure. In contrast, patients with impaired perception showed considerably decreased rectal adaptation but had similar anal pressure. CONCLUSION: Abnormal sensations during rectal distension are observed in one third of subjects suffering from incontinence. These abnormalities may reflect hyperreactivity or neuropathological damage of the rectal wall.  (+info)

Anal ultrasound predicts the response to nonoperative treatment of fecal incontinence in men. (6/1075)

OBJECTIVE: To assess the etiology, treatment, and utility of anal ultrasound in men with fecal incontinence and to review the outcomes of conservative (nonoperative) treatment. SUMMARY BACKGROUND DATA: The etiology of fecal incontinence in women is almost exclusively from obstetric or iatrogenic surgical injuries resulting in damage to the anal sphincters and/or pudendal nerves. Corresponding data on men with fecal incontinence are sparse. METHODS: Between January 1995 and January 1998, 37 men with fecal incontinence were evaluated in the John Radcliffe Hospital anorectal ultrasound unit. Their clinical histories, anal ultrasound results, anorectal physiology studies, and responses to conservative therapy were reviewed. RESULTS: Median age was 57 years. Major incontinence was present in 27% of the patients. Anal ultrasound localized anal sphincter damage in nine patients, and the characteristics of these nine patients with sphincter damage were then compared with the remaining 28 without sphincter damage. Prior anal surgery was more common in patients with sphincter damage. Hemorrhoids were more common in patients without sphincter damage. Anorectal physiology studies revealed significantly lower mean maximum resting and squeeze pressures in patients with sphincter damage, confirming poor sphincter function. With 92% follow-up, patients without sphincter damage were more likely to improve with nonoperative therapy. CONCLUSIONS: Anal ultrasound is extremely useful in the evaluation of fecal incontinence in men. Unlike women, the majority of men do not have a sphincter defect by anal ultrasound, and conservative management is usually successful in these patients. In contrast, in men with anal sphincter damage, almost all of these defects resulted from previous anal surgery. Conservative management rarely is successful in these cases, and surgical repair of the anal sphincter may be indicated. Therefore, because the presence or absence of sphincter damage on anal ultrasound usually predicts the response to nonoperative treatment, anal ultrasound should be used to guide the initial management of men with fecal incontinence.  (+info)

A bile acid-induced apoptosis assay for colon cancer risk and associated quality control studies. (7/1075)

Bile acids are important in the etiology of colorectal cancer. Bile acids induce apoptosis in colonic goblet cells at concentrations comparable to those found in fecal water after high-fat meals. Preliminary evidence indicated that cells of the normal-appearing (nontumorous) portion of the colon epithelium of colon cancer patients are more resistant to bile salt-induced apoptosis than are cells from normal individuals. In the present study, 68 patients were examined, and biopsies were taken at 20 cm from the anal verge, cecum, and descending colon. The patients included 17 individuals with a history of colorectal cancer, 37 individuals with adenomas, and 14 individuals who were neoplasia free. The mean bile salt-induced apoptotic index among normal individuals was 57.6 +/- 3.47 (SE), which differed significantly (P < 0.05) from the mean value of 36.41 +/- 3.12 in individuals with a history of colon cancer. The correlation between independent observers was 0.89 (P < 0.001), indicating good interobserver reliability. Components of variance comparing interindividual versus intraindividual sources of variation suggested that site-to-site variability, both between regions of the colon and for adjacent biopsies, was larger than the interpatient variability for individuals with a history of neoplasia. Therefore, there was "patchiness" of the susceptibility of regions of the colon to bile acid-induced apoptosis in individuals with a history of neoplasia (a patchy field effect). There was no obvious correlation of low-apoptotic index regions with regions in which previous neoplasias had been found and removed. On the other hand, for normal, i.e., neoplasia-free, individuals, there was relatively less intraindividual variation compared to interindividual variation. Our assay shows an association between resistance to bile acid-induced apoptosis, measured at 20 cm from the anal verge, and colon cancer risk. Thus, this assay may prove useful as a biomarker of colon cancer risk.  (+info)

Topographical and electrophysiological characteristics of highly excitable S neurones in the myenteric plexus of the guinea-pig ileum. (8/1075)

1. Most intracellular electrical recordings from myenteric neurones have been made from the centre of large ganglia. In this study, we examined the electrophysiological properties of neurones at the corners of large ganglia close to internodal strands and in microganglia. 2. Of 150 neurones in these locations: 111 were tonic S neurones; 9 were phasic S neurones and 30 were AH neurones. 3. Tonic S neurones were characterized by: (i) low resting membrane potentials (-50 +/- 1 mV, mean +/- s.e.m.); (ii) high input impedance (522 +/- 23 MOmega); (iii) low threshold for action potential (AP) generation (0.012 +/- 0.004 nA); (iv) firing of APs throughout a depolarizing pulse (duration <= 1 s) and one to four APs following a hyperpolarizing pulse and (v) spontaneous fast excitatory postsynaptic potentials (FEPSPs). A substantial proportion of tonic S neurones (43 %) also fired APs spontaneously (7.6 +/- 0.6 Hz; range, 0.3-19 Hz). All APs were blocked by tetrodotoxin (1 microM). 4. Tonic S neurones were subclassified, according to their post-stimulus responses, as SAH or SAD neurones. Following a burst of APs, SAH neurones exhibited a prominent after-hyperpolarization (duration, 711 +/- 10 ms) and SAD neurones an after-depolarization (duration, 170 +/- 10 ms). The after-hyperpolarization was reduced in four of ten neurones by apamin (0.3 microM). 5. FEPSPs were evoked in 20 of 38 S neurones by electrical stimulation applied both oral and anal to the recording site. Repetitive stimuli evoked slow excitatory postsynaptic potentials (SEPSPs) in some tonic S neurones. 6. Three functional classes of S neurones were identified after injection of neurobiotin through the recording microelectrode: (i) longitudinal muscle motor neurones, (ii) short circular muscle motor neurones, and (iii) ascending interneurones. 7. In conclusion, there appears to be topographical organization of highly excitable, tonic S neurones within the myenteric plexus, since, in contrast to other S neurones, they can be readily impaled in myenteric ganglia close to internodal strands and in microganglia.  (+info)

We aim to establish the evidence base for the recognition and management of obstetric anal sphincter injury (OASI) and to compare this with current practice amongst UK obstetricians and coloproctologists. A systematic review of the literature and a postal questionnaire survey of consultant obstetricians, trainee obstetricians and consultant coloproctologists was carried out. We found a wide variation in experience of repairing acute anal sphincter injury. The group with largest experience were consultant obstetricians (46.5% undertaking ≥ 5 repairs/year), whilst only 10% of responding colorectal surgeons had similar levels of experience (p | 0.001). There was extensive misunderstanding in terms of the definition of obstetric anal sphincter injuries. Overall, trainees had a greater knowledge of the correct classification (p | 0.01). Observational studies suggest that a new overlap repair using PDS sutures with antibiotic cover gives better functional results. However, our literature search found only
Obstetric anal sphincter injuries (OASIS) is the most common cause of fecal incontinence (FI) in women. Obstetric-related FI may occur early after childbirth. Previous obstetric injury is also a major cause of FI in older women, and risk of FI increases with time and further childbirths. FI is involuntary loss of solid or liquid stool. Symptoms range from fecal urgency, soiling, to daily passive or urge fecal incontinence. FI is a stigmatizing condition. It can have a distressing impact and restriction on quality of life, including isolation and depression.. Tears during delivery is classified (Sultan) as first degree tears including vaginal epithelium, second degree tears into the perineal muscle, third degree involving the anal sphincter complex and fourth degree including sphincter complex and anorectal epithelium. OASIS includes third and fourth degrees tears.. First line of therapy of FI is conservative treatment including drug therapy and biofeedback. If conservative treatment fails, ...
The anal and rectal area contains specialized muscles that are helpful to regulate proper passage of bowel movements.. Normally, when stool enters the rectum, the anal sphincter muscle tightens to prevent passage of stool at an inconvenient time. If this muscle is weak or does not contract in a timely way, incontinence (leakage of stool) may occur.. Normally, when a person pushes or bears down to have a bowel movement, the anal sphincter muscles relax. This will cause the pressures to decrease allowing evacuation of stool. If the sphincter muscles tighten when pushing, this could contribute to constipation. Anal manometry measures how strong the sphincter muscles are and whether they relax as they should during passing a stool. It provides helpful information to the doctor in treating patients with fecal incontinence or severe constipation.. There are many causes of fecal incontinence. Weak anal sphincter muscles or poor sensation in the rectum can contribute to fecal incontinence. If these ...
PURPOSE:. Paradoxical puborectalis contraction during defecation is one possible explanation for constipation. The degree of paradoxical contraction can be evaluated by intramuscular electromyography from the puborectalis and external anal sphincter muscles. This study aimed to determine whether a noninvasive technique with surface electrodes placed over the subcutaneous part of the external anal sphincter is feasible in the evaluation of paradoxical activity.. METHODS:. Twenty-five patients with constipation were studied. Sphincter muscle activity during strain and squeeze maneuvers was recorded using surface electrodes placed 1 cm from the anal verge. In addition, intramuscular recordings were made simultaneously from the external anal sphincter and puborectalis muscles. The degree of paradoxical activation was calculated as a strain/squeeze index. The patients were examined either in the left lateral position or sitting on a commode.. RESULTS:. The study revealed significant (P , .01) ...

The internal anal sphincter, IAS, (or sphincter ani internus) is a muscular ring that surrounds about 2.5-4.0 cm of the anal canal; its inferior border is in contact with, but quite separate from, the external anal sphincter. It is about 5 mm thick, and is formed by an aggregation of the involuntary circular fibers of the rectum. Its lower border is about 6 mm from the orifice of the anus. Its action is entirely involuntary, and it is in a state of continuous maximal contraction. It helps the Sphincter ani externus to occlude the anal aperture and aids in the expulsion of the feces. Sympathetic fibers from the superior rectal and hypogastric plexuses stimulate and maintain internal anal sphincter contraction. Its contraction is inhibited by parasympathetic fiber stimulation. This sphincter is tonically contracted most of the time to prevent leakage of fluid or gas, but is relaxed upon distention of the rectal ampulla, requiring voluntary contraction of the puborectalis and external anal ...
OBJECTIVES: The aim of this study was to determine sphincter volume, length, and external anal sphincter thickness in healthy controls and fecal incontinent patients by use of a three-dimensional reconstruction of endoanal ultrasonography images. MET
Anismus or spastic pelvic floor syndrome is thought to be one cause of severe constipation.2 7 Its pathophysiological basis is PSC during straining. However, there is no single test by which the diagnosis can be confirmed so it is possible that it is a laboratory artefact. None the less, operations to solve the problem by posterior division of the puborectalis muscle have been performed.8 During the past few years functional outlet obstruction has been widely acknowledged as a cause of chronic constipation. In organic diseases such as tumour stenosis, outlet obstruction is continuously maintained by a rectal tumour mass. On the other hand, in functional forms of outlet obstruction the physiology is normal when the patient does not defaecate and becomes pathological only during defaecation. Paradoxical sphincter contraction during straining has been claimed as one of the main causes of functional outlet obstruction.9 The concept of PSC as a specific finding in constipated patients has been ...
Fecal incontinence caused by overt anterior sphincter defects sustained during childbirth is usually treated by a delayed overlapping repair of the external anal sphincter. However, an obstetric trauma is frequently associated with disruption of the perineal body and loss of the distal rectovaginal septum. Data regarding a combined repair, consisting of restoration of the rectovaginal septum and perineal body, overlapping external anal sphincter repair, and imbrication of the internal anal sphincter, are scanty. PURPOSE: This prospective study was aimed at the following: 1) evaluating the clinical outcome of such an anterior anal repair in patients with fecal incontinence caused by obstetric trauma; 2) comparing the functional results with those obtained in a historical group of patients who underwent a conventional direct sphincter repair. METHODS: During the period between 1973 and 1989, 24 female patients (median age, 44 (range, 28- 67) years) with fecal incontinence underwent direct ...
Nitroglycerine (glyceryl trinitrate) is used for treatment of anal fissure, as it has muscle relaxant property.

Bloating Worsens Constipation. One condition that can trigger your internal anal sphincter muscle to tighten up is a big accumulation of gas (flatulence) in your colon. If you have so much gas that your abdominal area is puffed up, then the pressure from that quantity of gas in the colon triggers the internal anal sphincter muscle to tighten up and close.. In this case, you have to very first eliminate the pressure by getting a few of the gas out, prior to you attempt to have a defecation. The very best method to do this is by lying flat on your bed, doing some colonic massage, then lying flat once again and simply permitting your body to entirely unwind and release. Sleep, or check out a book, however rest totally flat in whatever position is comfy for you (in your corner, your stomach, etc) and enable the gas to come out, as your body is all set to launch it.. ColoZone Plus works to help with bowel regularity and constipation, colon cleanse, reduce stomach acid and also acts as a magnesium ...

The primary functions of the rectum and pelvic floor muscles are to prevent incontinence (loss of control) or accidental leakage and to allow defecation to occur.. The rectum is very elastic, which allows it to store food residues prior to a bowel movement. But it must also be stiff enough to funnel food residues toward the anus during a bowel movement.. The pelvic floor, located below the rectum, is made up of many different muscles including the puborectalis muscle and the external and internal anal sphincter muscles.. The rectum is surrounded by sensory nerves that detect the filling of the rectum with food residues. This sensation of rectal filling enables us to consciously or unconsciously squeeze the external anal sphincter to prevent incontinence until we can reach a toilet. These sensory nerves are also involved in reflexes that let the sphincter muscles relax during a bowel movement.. Bowel incontinence or accidental leakage ...

Objective: The aim of this study was to clarify the short-term results and surgical tips of down-to-up TME by TAMIS following trans-anal intersphincteric dissection (ISD+TAMIS-TME) for very low rectal cancer near the anus.. Methods: We experienced this procedure in thirty-one C-Stage lower rectal cancers locating within 5cm from the anal verge. In the first step of this procedure, transanal intersphincteric dissection was performed from 2cm distal side of the tumor till the level that the puborectal muscle was fully exposed and then placed Gelpoint path in the anal canal. Distal stump was closed to prevent cancer cell dissemination and irrigate the anal canal. Down-to-up TME was performed under pneumoperitoneum using conventional laparoscopic devices till the level of the peritoneal reflux. Next, we moved to the abdominal side and did conventional laparoscopic procedures to make resection of the ...

The objective of this study was to compare the long-term feasibility of robotic compared with laparoscopic ISR. Methods Between January 2008 and May 2011, consecutive patients who underwent robotic or laparoscopic ISR with coloanal anastomosis from seven institutions were included. Propensity score analyses were performed to compare outcomes for groups in a 1 : 1 case-matched cohort. The primary endpoint was 3-year disease-free survival. Results A total of 334 patients underwent ISR with coloanal anastomosis, of whom 212 matched patients (106 in each group) formed the cohort for ...
Education Event Dublin 2nd July 2019. The MASIC Foundation was set up in the UK in 2017 to assist mothers suffering from anal sphincter injuries in childbirth. Thankfully, most births are straightforward. When a mother delivers a baby through the birth canal they may suffer from some form of anal incontinence due to serious tears.. The Foundation aims to help mothers who often suffer in silence due to embarrassment and social stigma associated with their symptoms, unaware that there are any other mothers going through what they are experiencing.. In 2019, the MASIC Foundation held an education event in Dublin. The Womens Medical Negligence department at James McSweeney Solicitors were delighted to be invited to this event and we were able to extend the invitation to a number of women whom we represent.. We had the pleasure of listening to colorectal surgeons, physiotherapists, nurses and psychologists providing information to women. Mothers in attendance heard that over 10% of women having a ...

Abstract:. Anal canal duplication (ACD) is a rare congenital malformation, usually detected early in life. We report a case of a 67-year-old female with symptomatic ACD associated with a presacral cyst. Physical examination revealed an accessory opening located in the midline, posterior to the true anus. Imaging examinations, including fistulography, endoanal ultrasonography, and magnetic resonance imaging, revealed a blind-ending fistulous tract without connecting with the rectum and a presacral cyst posterior to the rectum. Complete surgical excision of the tract with cyst was performed through a posterior sagittal approach. Histologic examination revealed squamous epithelium lining and smooth muscle bundles, thereby confirming ACD. The postoperative course was uneventful, and the patient was doing well; no recurrence was observed 4 years after surgery. ACD can present for the first time in infants, children, and adults. Imaging examinations are useful for the diagnosis and preoperative ...
3D HPUS and endoanal MRI are equally adequate for the evaluation of perianal fistulas. Both methods are associated with similar discomfort and patients have no preference for either procedure.
Objective: This work aimed to analyze the association between maternal position at birth in spontaneous deliveries and the occurrence of anal sphincter tears (AST) given the lack of evidence related to the least traumatic birth position. Study design: A total of 7832 vaginal deliveries were included. Vaginal-operative deliveries and deliveries with fundal pressure were excluded. Birth positions on bed, in water, kneeling, and in a squatting position on a low stool were compared. Birth position on bed was considered as the reference group, and a logistic regression analysis adjusting for important fetomaternal parameters was performed. Results: The overall incidence of AST was 1.1%. AST rate was significantly increased in squatting (2.9%) and kneeling (2.1%) positions compared with birth position on bed (1.0%) or in water (0.9%). Logistic regression analysis revealed a significantly higher risk for ASTs in squatting (OR 2.92, CI 95% 1.04-8.18) and in kneeling positions (OR 2.14, CI 95% 1.05-4.37) ...

Im trying to find information on a rare anal canal cancer. My husband is 57 and has had Perianal Crohns Disease since his early 20s. Has never allowed an illeostomy to be performed. A rare (from what his doctors tell us) cancer was found in his anal canal. The tumor itself is actually filled with a gelatinous material which is the cancer, when debulked prior to treatment, the tumor was flat. My husband refused surgery and recently finished chemo/radiation therapy. 6 weeks with the infusion pump (5-FU) and 6 weeks radiation. Just wondering if anyone has infomation on this type of adenocarcinoma they can share. Thanks! ...
Intersphincteric resection (ISR) is a surgical approach that allows resection of low lying rectal cancers that abut or invade the sphincter complex while avoiding the creation of a permanent stoma. While removing a portion of or the entire internal anal sphincter, the goal of therapy is complete extirpation of the cancer while preserving the external sphincter for anastomosis and preservation of continence through the anal canal. The critical considerations revolve around cancer outcomes (local and distant recurrence rates), as well as bowel function/continence. ...

Anorectal symptoms following RTH for prostatic carcinoma are common and persist at least until 1 year after its completion and are associated with objective evidence of heightened rectal sensitivity.
Surgery, also called surgical resection, involves removing the tumor during an operation. The surgeon removes the area of the colon or rectum containing the tumor as well as nearby tissues and lymph nodes. If possible, the surgeon will then reconnect the healthy sections of the colon or rectum in a process called anastomosis, keeping the bodys waste-removal system operational.. Sometimes the area of anastomosis needs to be bypassed to allow more time for healing and to reduce the risk of a stool leak. This is usually done in the treatment of rectal cancer, especially after being treated with radiation and/or if the connection (or anastomosis) is close to the anal sphincter muscles. In those cases, the surgeon will create an opening in the wall of the abdomen and attach either part of the colon or part of the small intestine to the opening. This procedure is called a colostomy (if the colon is used) or ileostomy (if the small bowel is used), and the opening is called a stoma. A pouch is then ...

Grade 3a involves less than 50 % and grade 3b involves greater than 50 % of the EAS. The injury causes J. Gosling and A. Emmanuel a tear in the anterior portion of the muscles which is typically repaired primarily using an end--to--end or overlapping technique. Persisting sphincter defects cause dysfunction due to the mechanical disadvantage of an absent continuous muscular ring. There is much interest into the pathophysiology of incontinence in patients without a structural defect of the external anal sphincter, previously termed idiopathic faecal incontinence. The ability of normal volunteers to retain a saline enema was not hindered; in fact it improved in two cases. Pathophysiology of Anorectal Sensation Baldi et al. and Kamm et al. have shown reduced rectal sensation as tested by balloon and electrical stimulation in some patients with idiopathic constipation [89, 90]. This suggests a sensory neuropathy. This could be within the intrinsic supply within the rectal wall or the extrinsic nerve ...

This drug acts by expanding or dilating the blood vessels of the body which allows for more blood to flow to the heart. These days, they are available in bottles and can be sniffed directly. Isobutyl nitrite gives people a head rush on inhaling and the effects of this drug last a couple of minutes. Many people have reported their orgasms to last for longer periods when they sniffed poppers during sex. Men have reported enhanced erections after sniffing isobutyl nitrite and this could be well due to the increased blood flow in the body. Sometimes this drug is also used to relax the anal sphincter muscle region of a person.. There are a few precautions although which need to be taken before you sniff isobutyl nitrite. The effects of isobutyl nitrite can increase drastically during or immediately after physical exercise such as jogging, dancing, swimming etc. These effects may sometimes give people a slight headache or make them feel sick or weak. All of these effects wear off within a few minutes ...
During the early phases (phases 1 and 2), researchers assess safety, side effects, optimal dosages and risks/benefits. In the later phase (phase 3), researchers study whether the treatment works better than the current standard therapy. They also compare the safety of the new treatment with that of current treatments. Phase 3 trials include large numbers of people to make sure that the result is valid. There are also less common very early (phase 0) and later (phase 4) phases. Phase 0 trials are small trials that help researchers decide if a new agent should be tested in a phase 1 trial. Phase 4 trials look at long-term safety and effectiveness, after a new treatment has been approved and is on the market. ...

Under general anesthesia, the patient was placed in the lithotomy position. The port for the camera was created first at the umbilicus using the open method. Two 5-mm ports were inserted through the right upper and lower quadrants, and the upper port was placed where a diverting stoma would be created. Two needlescopic forceps (Endo-Relief™, Hope Denshi Co.,Chiba, Japan), with or without a trocar, were inserted into the left upper and lower quadrants. Thereafter, we performed the following procedures: ligation of the inferior mesenteric artery (IMA) and inferior mesenteric vein (IMV), dissection of the mesentery, total mesorectal excision with the preservation of the autonomic nerves, and dissection of the intersphincteric space. After transanal intersphincteric dissection, extraction of the specimens, and coloanal anastomosis, the ileostomy covering was created at the right upper port, and the abdominal drain was inserted into the right lower port..

Carcinoma of the anal canal is a rare malignancy representing approximately 2.5% of all gastrointestinal malignancies. It is estimated in 2015 that over 7,200 patients will be diagnosed with carcinoma of the anal canal in the United States, resulting in greater than 1,000 deaths (1). The incidence of this disease continues to rise steadily. A practicing oncologist will evaluate and treat less than one such patient per year. The majority of anal carcinoma arises within the mucosa of the anus and is of squamous cell histology (2). Traditionally, 74% to 90% of carcinomas of the anal canal are cured with the combined modalities of chemoradiation, reserving an abdominoperineal resection (APR) for salvage therapy of persistent or recurrent disease (3). This chapter focuses on treatment of squamous cell carcinoma of the anal canal and the potential innovative strategies that lie ahead. ...
The anal canal is the final segment of the gastrointestinal tract, extending between the rectum and the anus. It has an important role in defecation and maintaining faecal continence.
The dentate line marks the junction of these two structures as the anal canal continues more distally joining the perianal skin at the anal verge (Figure 2). The anal canal mucosa consists of stratified squamous epithelium and contains no hair follicles or sweat glands. At the anal verge, the anoderm thickens and includes hair follicles and other cutaneous appendages. Proximal to the dentate line, the rectal ampulla narrows to conform to the opening of the anal canal. In doing so, its mucosa takes on a pleated appearance, forming 8 to 14 convoluted longitudinal folds: the columns of Morgagni. Each adjacent column is connected at the dentate line by a flap of mucosa that forms a small anal crypt, normally 1 to 3 mm deep. Anal sepsis, cryptitis, perianal abscesses, and fistulas result from inflammation, obstruction, and infection of the crypts and glands. The anal wall is a continuation of the usual layers of the wall of the colon and rectum, and the innermost mucosal lining continues to the anal ...
NO is recognised as an important inhibitory neurotransmitter in the IAS. Previous studies showed that blockade of NO biosynthesis reduced the relaxation of muscle strips of the IAS induced by electrical stimulation and impaired the RAIR.3,5 In the present study, we extended the role of NO as an inhibitory neurotransmitter to the murine IAS: blockade of NO biosynthesis resulted in a reduction of both the in vitro and in vivo relaxation of the IAS. These findings were further corroborated by experiments in nNOS−/− mice. Isolated muscle strips relaxed significantly less whereas the RAIR was impaired compared with controls. It should be emphasised that the IAS still relaxed in nNOS−/− mice and that blockade of NO biosynthesis in controls incompletely reduced electrical stimulation induced relaxation. These observations suggest that either nitrergic blockade was incomplete or, most likely, that another inhibitory neurotransmitter is involved. Previous studies in the rat IAS suggested ATP as a ...

The external anal sphincter (or sphincter ani externus ) is a flat plane of muscular fibers, elliptical in shape and intimately adherent to the skin surrounding the margin of the anus. The external anal sphincter measures about 8 to 10 cm in length, from its anterior to its posterior extremity, and is about 2.5 cm opposite the anus, when defecation occurs the sphincter muscle retracts. It consists of two strata, superficial and deep. The superficial, constituting the main portion of the muscle, arises from a narrow tendinous band, the anococcygeal raphe, which stretches from the tip of the coccyx to the posterior margin of the anus; it forms two flattened planes of muscular tissue, which encircle the anus and meet in front to be inserted into the central tendinous point of the perineum, joining with the superficial transverse perineal muscle, the levator ani, and the bulbospongiosus muscle also known as the bulbocavernosus. The deeper portion forms a complete sphincter to the anal canal. Its ...

RESULTS: The study population included 2 570 847 deliveries. Episiotomy use declined significantly among operative vaginal deliveries (53.1% in 2004 to 43.2% in 2017, p , 0.0001) and spontaneous vaginal deliveries (13.5% in 2004 to 6.5% in 2017, p , 0.0001). Episiotomy was associated with higher rates of obstetric anal sphincter injury among spontaneous vaginal deliveries (4.8 with episiotomy v. 2.4% without; adjusted rate ratio [RR] 2.06, 95% confidence interval [CI] 2.00-2.11) and this association remained after stratification by parity and obstetric history. In contrast, episiotomy was associated with lower rates of obstetric anal sphincter injury among forceps deliveries in nulliparous women (adjusted RR 0.63, 95% CI 0.61-0.66), and women with vaginal birth after cesarean (adjusted RR 0.71, 95% CI 0.60-0.85), but not among parous women without a previous cesarean (adjusted RR 1.16, 95% CI 1.00-1.34). ...

The internal anal sphincter represents a thickening of the last annular fibers of the smooth colon muscles and is innervated by the sympathetic nervous system.. 2. The levator ani, however, has voluntary innervation (sacral plexus) and includes the puborectalis arising from the symphysis pubis. Since the course of the puborectalis creates a sling (deficient anteriorly) around the rectum, the latter becomes angulated.. 3. The external anal sphincter is also a striated muscle and extends from the center of the perineum (centrum ...
There are two anal sphincter muscles: an internal anal sphincter that is part of the intestines, and an external anal sphincter that is part of the pelvic floor muscles.. The internal anal sphincter normally stays closed to prevent the leakage of gas or liquid from the rectum, but when the rectum fills up with gas or fecal material, a reflex causes it to open to allow the bowel movement to pass through.. The nerves that this reflex depends on are sometimes missing at birth, with the result that the internal anal sphincter stays tightly closed and bowel movements cannot occur. This congenital (birth) defect is called Hirschsprungs disease.. Learn more about Hirschsprungs disease. ...
The aetiology of anal fissure is unclear, but there is an association with high maximum resting pressure (MRP). Internal sphincterotomy reduces MRP and heals fissure through an increase in local blood supply. Glyceryl trinitrate (GTN) is a nitric oxide donor which contributes to internal anal sphincter relaxation via a non‐adrenergic non‐cholinergic pathway. GTN ointment was applied topically in different concentrations to the anal margin in patients with chronic anal fissure to monitor its effect primarily on MRP and secondarily on fissure healing. Nineteen patients with chronic anal fissure were treated with ointment containing increasing concentrations of GTN (0·2-0·8 per cent) to produce a reduction in MRP of greater than 25 per cent. The actual dose of GTN varied as no standard delivery system has been developed, but a typical amount of GTN ointment weighed about 200 mg. In 15 of 19 patients, a concentration greater than 0·2 per cent was required to lower the MRP by at least 25 per cent.

Dr. Zadeh responded: Sphincterotomy. Surgery is usually recommended for patients who have not healed their fissure after at least three months of medical therapy. Surgical treatment for anal fissures is highly effective and recurrence is low. The procedure is called a lateral internal sphincterotomy and involves cutting a portion of the internal anal sphincter muscle. This helps the fissure heal and decreases pain and spasm.
Faecal incontinence (FI) is a debilitating and often neglected problem. It can be defined as the loss of voluntary control of liquid or solid stool.It is estimated that 2-3% of western adults suffer from FI with prevalence increasing with age, further to this up to 50% of nursing home residents suffer too with it more common in females. Aetiology is often multi-factoral, where obstetric anal sphincter injury is most common is females and iatrogenic anal sphincter injury is most common in males.. Loperamide (imodium) is a constipating agent used as first choice pharmacological agent due to its high efficacy. Trials have suggested it thickens stool consistency and may raise resting anal sphincter pressure, associated with improved clinical function with a reduction in bowel frequency and urgency, a reduction in incontinence and less need for pads.. Loperamide is well tolerated but has been known to cause side effects of abdominal pain and distension, nausea and vomiting and constipation.. Imodium ...
BACKGROUND: This single-center, prospective, randomized trial was designed to compare the short-term clinical outcome between laparoscopic-assisted versus open total mesorectal excision (TME) with anal sphincter preservation (ASP) in patients with mid and low rectal cancer. Long-term morbidity and survival data also were recorded and compared between the two groups.. METHODS: Between August 2001 and August 2007, 80 patients with mid and low rectal cancer were randomized to receive either laparoscopic-assisted (40 patients) or open (40 patients) TME with ASP. The median follow-up time for all patients was 75.7 (range 16.9-115.7) months for the laparoscopic-assisted group and 76.1 (range 4.7-126.6) months for the open group. The primary endpoint of the study was short-term clinical outcome. Secondary endpoints included long-term morbidity rate and survival. Data were analyzed by intention-to-treat principle.. RESULTS: The demographic data of the two groups were comparable. Postoperative recovery ...

Transanal endoscopic microsurgery (TEM) and transanal minimally invasive surgery (TAMIS) are similar techniques that allow surgeons to remove benign polyps and early stage cancers without the use of invasive surgery.. More about TEM. Developed in the 1980s, TEM was created to enable surgeons to remove polyps and tumors in the rectum using a port placed through the rectum and a microscopic lens. This technology has demonstrated precise excision of polyps and tumors with preservation of anal sphincter muscle control.. More about TAMIS. TAMIS was developed in 2009 and has been utilized for the same indications as TEM.. What is the difference between TEM and TAMIS? The primary difference between the two techniques is that a resterilized, reusable port is used for TEM, while a disposable port is used for TAMIS.. What are the benefits of TEM and TAMIS?. Many benefits have been noted for patients undergoing TEM and TAMIS: no visible incisions, decreased postoperative pain, faster recovery, and a ...
A. The rectum is empty. There is no urge to defecate.. B. Stool enters the rectum and stretches the rectal wall, causing a sensation of fullness.. C. Rectal wall distention causes relaxation of the internal anal sphincter, allowing the stool to descend into the proximal anal canal. This movement causes awareness that stool passage is imminent.. D. The pelvic floor muscles contract to maintain continence, moving the stool upward and out of the anal canal.. E. If the stool remains in the rectum after the pelvic floor returns to its resting state, then stool will no longer be in contact with the anus. The rectal wall relaxes; reducing the pressure and wall tension, and the urge to defecate abates.. F. Defecation occurs when the pelvic floor relaxes, and the pressure in the rectum is greater than pressure from the external anal sphincter and the pelvic floor.

In some cases, surgery can damage the anal sphincter muscles (the ring of muscles that open and close the anus). If the muscles are damaged, you may lose control of your bowels, leading to faeces leaking uncontrollably from your rectum (the area where they are stored). This is known as faecal or bowel incontinence.. The likelihood of incontinence occurring after surgery will depend on the type of surgery you had and the position of your fistula. If you had some bowel incontinence before surgery, this may get worse.. Incontinence after a fistulotomy (surgery that opens up the fistula) is more common in women and in people with Crohns disease, a condition that causes inflammation of the lining of the digestive system. Rates of incontinence vary, although most studies report incontinence in between 3% and 7% of people.. After using seton techniques, the incontinence rate is 17%, and after an advancement flap procedure the incontinence rate is around 6-8%. Ask your Dr. B C Shah about the risks ...

Most patients who cannot have a J- or S-pouch will have a permanent ileostomy bag. However, the Kock pouch, or K-pouch, is an alternative to a regular (end) ileostomy. The K-pouch is used in cases of ulcerative colitis when the large intestine and rectum need to be removed because of disease and the anal sphincter muscles are weak, or because a J- or S-pouch cannot or should not be made.. About 16 inches (40 cm) of the last portion of the small intestine are used to build an internal reservoir, which is then attached to the inside of the abdominal wall. A small opening called a stoma leads out and is used several times a day to drain waste matter through a catheter (tube) inserted into the K-pouch.. Three loops of the small intestine, each about 12 inches long (about 30 cm), are stitched or stapled together to form the pouch. Another length of intestine, approximately 4 inches (about 10 cm), is used to make a valve or nipple between the stoma and the pouch. The nipple acts as a flap valve to ...
The most recent estimates, and statistics show that the future of cold and flu, most people visit their doctors, because it hurts the various parts of the body. While it is normal to come back pains after -particularly aches- a stressful or hectic day exercise, back pain is often a result of constipation. Other causes pain to the back of stress, excessive walking, degenerative disc disease, climbing stairs, bending, heavy lifting and standing for long periods. If the above-mentioned non-common part of daily activities, and then constipation, it is likely that there are a bout of back pain and constipation. Straining to pass hard stool can cause pain in the lower back. It hurts happens because the anus and inflamed because of the stress put on it when trying to defecate. Children are also known to suffer from these problems. Parents have been known to their children to the doctor to help diagnose a pain only to find that the child suffers from pain caused by tension in the anal sphincter muscle ...

By Karen Zaghiyan, MD, and Phillip Fleshner, MD. Neoadjuvant chemoradiation followed by proctectomy with total mesorectal excision (TME) is the standard of care in the management of locally advanced rectal cancer. Unlike cancers of the colon, rectal cancer has always posed a unique challenge to the surgeon due to the narrow working space in the bony pelvis and the intimate relationship between the rectum and the pelvic autonomic nerves, vascular structures and the anal sphincter complex.. In the 19th century, survival from rectal cancer was nil. In 1908, Sir William Ernest Miles revolutionized the surgical management of rectal cancer when he published his experience with the simultaneous abdominoperineal approach. After this milestone in rectal cancer surgery, survival improved but remained under 50 percent. The next breakthrough in rectal cancer surgery was the concept of TME described by Bill Heald in 1982. Sharp dissection in the avascular plane between the mesorectum and the pelvic autonomic ...
Dont be a tight-ass. The thoracic diaphragm has anatomical and neurological connections to the pelvic floor via the levator ani muscle group. There will not be a quiz, but know that when this section of the pelvic floor contracts it tucks the tail bone (coccyx) under. That predisposes the lumbar spine to round backwards which sets the dominos in motion to slump which compromises ideal respiratory function. Know that this action may also reflect a guarded/emotional environment. Some individuals never let go. I had a patient who had habituated to this action and subsequently it was discovered that when they were able to release their fear of spontaneous evacuation and relax their external sphincter much of their back pain resolved ..Note: there are two anal sphincters; the internal sphincter, comprised of smooth muscle is controlled involuntarily via autonomic mechanisms (thank goodness). It keeps stuff in..most of the time. The external anal sphincter, comprised of striated muscle is ...
|i|Background.|/i| Intersphincteric resection (ISR) has been a preferable alternative to abdominoperineal resection (APR) for anal preservation in patients with low rectal cancer. Laparoscopic ISR and robotic ISR have been widely used with the proposal of 2 cm or even 1 cm rule of distal free margin and the development of minimally invasive technology. The aim of this review was to describe the newest advancements of ISR. |i|Methods.|/i| A comprehensive literature review was performed to identify studies on ISR techniques, preoperative chemoradiotherapy (PCRT), complications, oncological outcomes, and functional outcomes and thereby to summarize relevant information and controversies involved in ISR. |i|Results.|/i| Although PCRT is employed to avoid positive circumferential resection margin (CRM) and decrease local recurrence, it tends to engender damage of anorectal function and patients’ quality of life (QoL). Common complications after ISR include anastomotic leakage (AL),
PURPOSE: To compare GI symptoms, measures of generic and disease specific health related quality of life (HRQoL), anorectal and pudendal nerve function and anal sphincter morphology between (i) patients ≥2 years after 3D conformal radiotherapy (3D-CRT)±high dose rate (HDR) brachytherapy for carcinoma of the prostate and aged matched patients before radiotherapy and (ii) symptomatic and asymptomatic patients ≥2 years after 3D-CRT ± HDR brachytherapy. MATERIAL AND METHODS: Methodology included: (i) modified LENT-SOMA scales for GI symptoms, (ii) EORTC QLQ-C30 and EORTC QLQ-PR25 questionnaires for generic and disease specific HRQoL, (iii) anorectal manometry and terminal motor latency for anorectal and pudendal nerve function and (iv) endorectal ultrasound for anal sphincter morphology ...
We studied 386 anal cancers to examine the association between HPV status and histopathological characteristics in detail. Overall, we detected hrHPV in 90% of invasive anal cancers in women and 63% of those in men. Using in situ hybridization and HPV-16-specific PCR in 99 patients, Holm et al. (9) found HPV in similar proportions of anal canal cancers in women (89%) and men (56%). Another study of 93 women and 36 men with in situ or invasive anal cancer showed 70% of the tumors in women and 67% of those in men to be PCR positive to one or more of HPV-6, -11, -16, and -18, but a distinction between anal canal cancers and perianal skin cancers was not presented (8) .. Whether cancers involving the anal canal contain HPV more often than perianal skin cancers has been the subject of only few investigations. One study reported more HPV-16 in cancers originating above than below the dentate line (17 , 18) , and another small study detected HPV-16 by DNA in situ hybridization in 81% of anal canal ...

Caused by trauma to the anus and anal canal due to bowel movement, anal fissure is a cut or tear occurring in the anus that extends up into the anal canal. Anal fissures are fairly common in men as well as women and can occur at any age including infancy. Symptoms of fissures include the patient suffering from anal pain that worsens with bowel movements. This pain may be bearable or severe in some cases. Sometimes the pain can also affect urination and cause discomfort while urinating, inability to urinate or frequent urination. To suggest an appropriate fissures treatment the doctor needs to first diagnose and evaluate the problem. This means the doctor will inspect the anus to confirm the presence of a fissure before suggesting a mode of treatment.. The goal of any anal fissures treatment is to break the cycle of spasm of the anal sphincter and discontinue its repeated tearing of the anoderm. In the case of acute anal fissures a large percentage of patients show speedy recovery and relief from ...

AIM Anorectal varices are an uncommon, but significant, source of bleeding in patients with portal hypertension. The aim of this article was to review systematically the available literature on the aetiology, clinical presentation and management of anorectal varices, and to suggest a simple treatment algorithm based on available evidence and local expertise. METHOD A systematic literature search was carried out to identify articles on anorectal varices, and the search strategy identified 57 relevant references. The inclusion criteria included a consecutive cohort of patients having treatment for anorectal varices with details of success rates and the number of different techniques used. Exclusion criteria included papers published in languages other than English with no English version and results not reported separately for anorectal varices. RESULTS Anorectal varices can occur in up to 89% of patients with portal hypertension, although the overall incidence in the general population is low.
RESULTS: The mean time to pain relief was 8.45 (standard deviation (SD) 7.41) days in group 1 and 7.20 (SD 7.19) days in group 2. Healing took place in a mean of 5.20 (SD 1.85) weeks in group 1 and 5.40 (SD 2.01) weeks in group 2. Fissures failed to heal in 2 patients in group 1 and 3 in group 2, and recurred in 4 patients in group 1 and 3 in group 2 ...
