OBJECTIVE To evaluate the impact of transanal endoscopic microsurgery (TEM) on postoperative anal function and quality of life in patients with benign rectal tumor and early rectal cancer. METHODS Clinical data of 50 patients with rectal adenoma and early rectal cancer undergoing transanal endoscopic microsurgery in our hospital from October 2008 to June 2013 were retrospectively analyzed. Anorectal manometry, endorectal ultrasonography (ERUS), the fecal incontinence severity index (FISI), and the physical and mental health status scores (SF-36) were used to evaluate preoperative and postoperative anorectal function and quality of life. RESULTS Anorectal manometry indicated anal resting pressure (ARP), maximum squeeze pressure (MSP), rectal volume at sensory threshold(RVST), maximum tolerable volume(MTV) decreased significantly at the first month after surgery (P|0.05). MSP returned to preoperative level at the 3rd month (P|0.05). ARP and MTV returned to normal values at the 6th month (P|0.05). RVST

The standard treatment of rectal adenocarcinoma is total mesorectal excision (TME). The technique involves a low anterior rectal or colo-anal resection, very often associated with a protective stoma or abdominal-perineal resection with permanent colostomy. Transanal endoscopic microsurgery (TEM) allows access to tumors up to 20 cm from the anal margin, with minimal postoperative morbidity and mortality. Recent studies of T1 rectal adenocarcinomas consider TEM to be the technique of choice. However the treatment of T2 rectal cancers remains controversial. Chemotherapy and radiotherapy (CT/RT) has achieved a concomitant reduction in local recurrence and an increase in survival.. Hypothesis: Patients with rectal adenocarcinoma less than 10 cm from the anal margin and up to 4 cm in size, staged after endorectal ultrasound and MRI as T2 or superficial T3 N0-M0-N0-M0, who underwent surgery after preoperative local chemoradiotherapy (TEM), achieve effective results in terms of local recurrence similar ...
Definition. Transanal Endoscopic Microsurgery (TEM), is a minimally invasive surgical technique used to remove certain rectal polyps and early stage rectal tumors that cant be removed by colonoscopic resection. Tumors located high inside the rectum can now be removed using the TEM technique and specialized equipment, that otherwise would be accessible only through more invasive, "open" abdominal surgery.. Benefits. ...
41 patients underwent transanal excision using TEMS (KARL-Storz) or single port TAMIS (Covidien) kits. All patients went through the colorectal MDT with standardized MRI reporting. Average age was 70yrs (range=40-86). Mean hospital stay was 2.7 days. Complications- 1 had post-operative bleeding that required repeat surgery; 1 developed a pre-sacral collection that was treated with antibiotics.. 13 patients had tubulo-villous adenoma with high-grade dysplasia, 9 had invasive adenocarcinoma demonstrated on histology (3=T1SM1, 3=T1SM2, 3=T1SM3) and 1 had neuroendocrine tumor, others demonstrated benign dysplasia (15 had tubulo-villous adenoma with low-grade dysplasia, 3 with sessile serrated adenomas). 8/9 cancers had R0excision. One patient with T1SM3, who had R1 excision and another with T1SM2 and poor prognostic features on histology, underwent adjuvant chemoradiation. All patients had flexible sigmoidoscopy at 3 months. 5/41 had recurrent benign polyps (3 underwent endoscopic resections, 2 ...

Anal cancer is often detected during a routine rectal examination or procedure, such as hemorrhoid removal, though it is usually identified by a patient reporting symptoms. During a digital rectal exam, a medical provider inserts a lubricated, gloved finger into the anus to feel for any abnormalities. He or she may also perform an anoscopy or proctoscopy (examination of the anus and rectum using a short, lighted tube). If anal cancer is suspected, the doctor will perform a biopsy. If anal cancer is diagnosed, staging tests to determine whether the cancer has spread may include abdominal and pelvic CT scan, a pelvic MRI scan, a chest X-ray, and liver function tests. Treatment for anal cancer depends on the stage of the disease. Stage 0, carcinoma in situ, indicates that abnormal cells have been identified in the area but have not become cancer. Stage I indicates a tumor measuring 2 centimeters or smaller, while Stage II indicates a tumor larger than 2 centimeters. Stage IIIA and IIIB describes a ...
The question asked on the BRFSS about colorectal cancer screening has changed over time. In 1993 and 1995, survey respondents were asked whether they had ever had a proctoscopic exam and the length of time since the last exam. In 1997, respondents were asked whether they had ever had a sigmoidoscopy or proctoscopy and the length of time since the last exam. In 1999-2000 respondents were asked whether they had ever had a sigmoidoscopy or colonoscopy and the length of time since the last exam. From 2001 to present, data has been based on sigmoidoscopy or colonoscopy or fecal occult blood testing and the length of time since the last exam. Data from the New Jersey Risk Factor Survey are intended to represent non-institutionalized adults in households with telephones. Data are collected using a random sample of all possible telephone numbers. Prior to analysis, data are weighted to represent the population distribution of adults by age, sex, and "race"/ethnicity. As with all surveys, however, some ...
An endoscopy is performed with either a flexible endoscope (bronchoscopy, colonoscopy, or endoscopy) or with a rigid endoscope (arthroscopy, cystoscopy, laparoscopy, proctoscopy, rhinoscopy, or thoracoscopy). The machine is made up of a tube that enters the body, an eyepiece, and a control section for the doctor to maneuver the equipment. Additionally, there are two channels within the endoscope. One channel can be used for various endoscopic tools to collect fluids or samples, and the other allows air or water to pass through. Special video cameras can also be attached that allow viewing of the procedure on a screen or recording a video of the procedure. Endoscopies performed on humans only require light sedation, however, because animals dont understand that a veterinary team is trying to help them, they will need to be sedated under general anesthesia for the duration of the procedure. ...
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 ...
BACKGROUND: Transanal endoscopic microsurgery (TEM) allows locally complete resection of early rectal cancer as an alternative to conventional radical surgery. In case of unfavourable histology after TEM, or positive resection margins, salvage surgery can be performed. However, it is unclear if the results are equivalent to primary treatment with total mesorectal excision (TME). The aim of this retrospective study was to determine whether there is a difference in outcome between patients who underwent early salvage resection with TME after TEM, and those who underwent primary TME for rectal cancer. METHODS: From 1997 to 2011, early salvage surgery with TME after TEM was performed in 25 patients in our institution. These patients were compared with 25 patients who underwent primary TME, matched according to gender, age (±2 years), cancer stage and operative procedure. Data were obtained from the patients charts and reviewed retrospectively. No patients received preoperative chemotherapy. ...

In the study of 15 patients with ischemia of the colon, researchers found that rigid proctoscopy was normal or demonstrated nonspecific proctitis in 12 of 15 patients studied. Colonoscopic biopsies demonstrated superficial inflammatory changes in all patients. Thirteen patients had complete mucosal healing endoscopically in 2 weeks to 3 months with stricture developing in four patients. Because ischemic colitis is a distinct subtype of ischemic bowel disease most often limited to the superficial mucosa, colonoscopy is an alternative and usually safe modality in the diagnosis of this entity and proved more accurate that conventional x-ray and proctoscopy(97 ...
METHODS AND PROCEDURES From January 2001 to December 2010, total 299 patients with colorectal carcinoid tumors were treated at the National Cancer Center, South Korea. Among of them, we excluded patients who had metastatic disease(n=10), who underewent radical operation(n=33), who were diagnosed in other hospitals(n=83) and who had colon carcinoid tumors(n=3). Finally, 170 patients with 175 rectal carcinoid tumors, who treated with local excision including endoscopic resection and surgical resection were enrolled this study. A pathologically complete resection(P-CR) was defined as an en bloc resection with tumor-free lateral and deep margin. Local treatment methods were classified to conventional polypectomy including strip biopsy, snare polypectomy and hot biopsy, advanced endoscopic techniques including endoscopic mucosal resection with cap(EMR-C) and endoscopic submucosal dissection(ESD) and surgical local excision including transanal excision(TAE) and transanal endoscopic microsurgery(TEM). ...
Background: There are a variety of surgical approaches for correction of ODS, most of these have high recurrence and complication rates. Stapled transanal rectal resection (STARR) was introduced in 2003 by Antonio Longo as a minimally invasive transanal operation for ODS associated with rectocele and or rectal intussusception.. Objective: This study was designed to assess the efficacy of Stapled Transanal Rectal Resection (STARR) as a surgical treatment of Obstructed Defecation Syndrome(ODS).. Methodology: This is a quasi experimental study that was carried out at Colorectal surgery unit of surgery department in Bangabandhu Sheikh Mujib Medical University. The sample size was 17. The admitted patient of Obstructed Defecation Syndrome with Rectocele and or Rectal intussusception was selected according to inclusion and exclusion criteria. The patient was evaluated by history, clinical examination, proctoscopy, colonoscopy and defecography. Preoperative Longos ODS score was determined for each ...

George Molina, MD, Liliana Bordeianou, MD, Paul Shellito, MD, Patricia Sylla, MD. Massachusetts General Hospital. INTRODUCTION: Peritoneal entry with loss of pneumoperitoneum during TEM can be safely managed with full-thickness suture closure in experienced hands. Early results with transanal minimally invasive surgery (TAMIS) demonstrated preliminary safety, but the overall experience with upper rectal tumors across multiple platforms is limited.. METHODS: Transanal endoscopic surgery cases performed at a single institution between 2008 and 2014 were retrospectively reviewed. Surgical indications, patient and lesion variables, intraoperative complications and 30-day postoperative morbidity were analyzed. Fishers exact test was used to compare categorical variables.. RESULTS: 78 transanal endoscopic procedures were performed in 76 patients including 40 females and 36 males with mean age of 61 (range, 21-86). Procedures were performed using the rigid TEO (65.4%), rigid TEM (26.9%), or TAMIS ...
In 2007, Whiteford et al. described the first transanal NOTES radical sigmoidectomy in human cadavers. Currently, the transition on human application is increasingly observed. Although instrument and platform limitations are still a barrier to pure applications of transanal NOTES resection, ongoing work has resulted in worldwide human clinical case reports. In this video, Dr. Patricia Sylla presents a clinical case of a pilot study of laparoscopic-assisted transanal endoscopic rectal cancer resection ...
BACKGROUND: Being grade 2 is a known risk factor for metastasis in rectal neuroendocrine tumors (R-NETs). We aimed to identify the efficacy of the Ki-67 labeling index (LI) in endoscopic biopsy specimens to predict the World Health Organization (WHO) grade of R-NETs. METHODS: A total of 59 patients with 60 R-NETs (43 WHO grade 1 and 17 WHO grade 2), treated between October 2002 and December 2014, were retrospectively evaluated. The patients included in the study underwent biopsies followed by endoscopic submucosal resection with a ligation device, trans-anal full-thickness surgical resection, or radical surgery with lymph node dissection ...
A compression and ligation device includes a pair of jaws including one or more Doppler chips oriented to send and receive Doppler signals across the jaws, to assist a practitioner in determining whether or not a uterine artery is between the jaws. A suture leader with an attached suture can be pushed through a channel on one of the jaws, through tissue behind the uterine artery, into another channel on the other jaw, and proximally out the device so that the practitioner can ligate the artery and effect hemostasis.
INTRODUCTION: Transanal minimally invasive surgery (TAMIS) is an endoscopic operating platform for local excision of rectal neoplasms. However, it may be technically demanding, and its learning curve has yet to be adequately defined. The objective of this study was to determine the number of TAMIS procedures for the local excision of rectal neoplasm required to reach proficiency. METHODS AND PROCEDURES: All TAMIS cases performed from 07/2009 to 12/2016 at a single high-volume tertiary care institution for local excision of benign and malignant rectal neoplasia were identified from a prospective database ...

El tratamiento de la dehiscencia de sutura después de cirugía oncológica del cáncer de recto supone un reto quirúrgico. El objetivo de este trabajo es mostrar como la cirugía transanal combinada con el abordaje abdominal es una herramienta muy útil para decidir el tratamiento individualizado en función del grado de dehiscencia y ayudarnos al manejo local de la misma. Presentamos tres casos de pacientes con dehiscencia de sutura colorectal. En dos de ellos se muestra el tratamiento de una dehiscencia colorectal aguda y como la cirugía transanal nos permite comprobar la viabilidad y descartar isquemia subyacente. Por otro lado, nos facilita un buen drenaje de la colección adyacente; así como si es necesaria la colocación de un sistema vaccum y de sus recambios siguientes. El último caso se trata de una dehiscencia tardía con sinus presacro crónico, y su tratamiento mediante acceso transanal para destechamiento del mismo.. ...

Hemorrhoids are either inside the anus (internal) or under the skin around the anus. Hemorrhoids may result from straining to move stool. Hemorrhoids are common. In the USA, the prevalence is about 4.4%. It is estimated that approximately one half of all Americans have had this condition by the age of 50, and that 50% to 85% of the worlds population will be affected by hemorrhoids at some time in their life. However, only a small number seek medical treatment. Annually, only about 500,000 people in the U.S. are medically treated for hemorrhoids, with 10 to 20% of them requiring surgeries. Hemorrhoids are very common in both men and women. About half of all people have hemorrhoids by age 50. The most common symptom of hemorrhoids inside the anus is bright red blood covering the stool, on toilet paper or in the toilet bowl. Hemorrhoids develop from 2 different places. There are 2 sets of veins that drain the blood from the lower rectum and anus. Hemorrhoids are very common in both men and women. ...
