A cuff is used to provide a form for curing fluid about the exterior of an end-to-end anastomosis site. The cuff includes a port through which fluid may be injected to reach an interior space defined between the exterior of tissue at the anastomosis site and the inner surface of the cuff. A circular stapler may be used as a mandrel for the cuff and fluid. Alternatively, inflatable balloons may be used as a mandrel. The curing fluid may comprise a mixture of fibrin and thrombin.

PURPOSE: Functional results after low anterior resection with straight coloanal anastomosis are poor. Although certain functional aspects are improved with

The experiments in this report were designed to evaluate the effect of superficial temporal-middle cerebral artery (STA-MCA) anastomosis on the course of middle cerebral artery (MCA) occlusion by emboli while avoiding a vessel clipping technique as well as the use of long-acting barbiturate anesthesia. Dogs were divided into 3 general groups: A) embolus placement 1 h following anastomosis; B) embolus placement 5 h prior to anastomosis; C) control group without anastomosis. Anastomosis prior to MCA occlusion has a favorable clinical effect and reduces the size of an infarction. Anastomosis 5 h after embolus placement is deleterious unless other therapeutic modalities can be shown to delay the course of infarction. ...

AU - Tominaga, Ryuji. PY - 2013/5. Y1 - 2013/5. N2 - For the purpose of examining the clinical applicability of a newly developed surgical sealant, animal experiments were performed, and clinical trial was followed. In animal experiments, several animal models, including carotid artery anastomosis model and coronary artery bypass grafting model were undertaken. In each model, complete hemostasis of the anastomoses using four simple interrupted sutures, was obtained. In addition, elastomeric property of the sealant prevented thinning of the arterial wall. The clinical trial performed in patients with thoracic aortic surgery showed significantly better hemostasis even under heparinized condition. Based on these excellent results, clinical usage of the sealant was approved.. AB - For the purpose of examining the ...

Patient was in the right lateral decubitus position with the lower body slightly tilted to the left, and a left thoracoabdominal incision was performed. The cardiopulmonary bypass was established by a venous cannula placed in the right atrium through the left femoral vein and 2 arterial return cannulas inside both femoral artery and ascending aorta. If the proximal thoracic descending aorta was not involved by the aneurysm and was long enough for both clamping and anastomosis (usually Crawford extent III TAAA), proximal aortic anastomosis was performed under mild hypothermic cardiopulmonary bypass and beating heart. otherwise, it was performed using an open technique with profound hypothermic circulatory arrest.. During our modified multiple branched graft replacement of TAAA, the proximal aortic anastomosis was performed first. After a proximal aortic clamp was placed just distal to the left subclavian artery or profound hypothermic circulatory arrest was established, a distal aortic clamp was ...

Distal anastomosis devices and associated methodology are described herein. Connector and connector components as well as tools associated therewith are disclosed. The connectors are preferably adapted to produce an end-to-side anastomosis at a graft/coronary artery junction. A fitting alone, or a fitting in combination with a collar may be used as a connector. Each fitting may be deployed by deflecting its shape to provide clearance for a rear segment that rotates about adjoining hinge section(s) so to fit the connector within an aperture formed in a host vessel. Upon return to a substantially relaxed position, a rear segment anchors the fitting it in place. The distal fitting may include additional side features for interfacing with the host vessel/coronary artery. The collar may include features complimentary to those of a fitting and provisions for strain relief and securing the graft vessel.

Methods and devices use magnetic force to form a magnetic port in a hollow body. Additional methods and devices form anastomoses between two or more hollow bodies. First and second anastomotic securing components create a fluid-tight connection between the lumens of the hollow bodies. End-to-side, side-to-side and end-to-end anastomoses can be created without using suture or any other type of mechanical fasteners, although mechanical attachment structure may be used in conjunction with the magnetic attachment. The securing components have magnetic, ferromagnetic or electromagnetic properties and may include one or more materials, for example, magnetic and nonmagnetic materials arranged in a laminated structure. The system of anastomotic securing components may be used in many different applications including the treatment of cardiovascular disease, peripheral vascular disease, forming AV shunts, etc. The system may be sized and configured for forming an anastomosis in or between a specific hollow body,

Head and neck anastomosis techniques present common aspects with any type of anastomosis but their localisation at the junction of the respiratory and digestive tracts makes them often delicate to perform. In the present article, we first review the different surgical indications and the laryngeal, tracheal, pharyngeal and oesophageal anastomosis techniques. The main types of flaps also used for this purpose are highlighted. We then review the cases observed during the 5 last years in our department, type and technique of surgery used. In this general review, we illustrate our stand point although aware of the multiple variants favoured by different schools. ...

INTRODUCTION. Conventional vascular anastomosis requires extensile exposure, circumferential dissection and temporary occlusion of the vessels. This technique was initially described by Alexis Carrel, in 1902[1], and despite several technical improvements it has remained basically the same.. Several devices for sutureless anastomosis were developed since that time, as grafts with rings[2], connectors[3], clips[4] and even magnets[5].. In complex aortic surgeries, the time to perform an anastomosis is related to ischemic and reperfusion injuries and can lead to renal failure, mesenteric ischemia and systemic inflammatory response. Thus, is advisable to simplify and shorten this period of the surgery.. In 2008, Lachat et al.[6] described a technique of sutureless anastomosis by telescoping a stent graft (Viabahn, W. L. Gore & Associates, Flagstaff, AZ) in order to facilitate complex vascular reconstruction in debranching procedures for thoracoabdominal aneurysms. The advantages of this technique ...

AU - Palmer, Kevin. AU - Lalka, Stephen G.. AU - Unthank, Joseph L.. PY - 1990. Y1 - 1990. N2 - The milliwatt CO2 laser was used to perform end‐to‐end anastomoses in canine jugular veins. There was a high disruption rate (50%) in laser‐welded veins (n = 10). Fibrin glue (n = 17), formed from human fresh‐frozen plasma, enhanced the weld strength decreasing the disruption rate (18%), resulting in an 82% patency which nearly equaled the contralateral sutured vein patency (93%). The bursting strength was improved with fibrin glue. Transmural necrosis was present initially in all groups but extended for a longer distance in the vessel wall in laser‐welded anastomoses. Sutured anastomoses exhibited a greater inflammatory response. In laser‐welded anastomoses endothelial cells were not as confluent as in ...

A method and instruments used to performing an end-to-end anastomosis between two portions of intestinal tissue is disclosed. The method involves drawing a first portion of intestinal tissue over a portion of a bioabsorbable stent. The end of the first portion of intestinal tissue is everted on the stent to create a collar of exposed inner intestinal tissue. A second portion of intestinal tissue is drawn over the stent and over the exposed intestinal tissue. A bandage containing one adhesive compound selected from the group of an adhesive and an adhesive initiator is wrapped about the juncture. The other adhesive compound is applied to saturate the bandage and the combination of an adhesive and an adhesive initiator sets the adhesive to adhere the first portion and the second portion of adhesive to the bandage.

In the presence of risk factors, the anastomosis in the small intestine and in the colon are at risk for dehiscence and peritonitis. The apposition of a biological patch around the anastomosis might improve wound healing and therefore might prevent harmful, potentially life-threatening and costy complications. Aim: to verify if Tutomesh® facilitates the functional recovery of the intestinal anastomotic wound area (mucosa) in the pig ileum and colon. Methods: 24 Large White pigs (B.W. 25 kg; age 4-5 months) underwent ileal and colonic anastomosis with or without application of Tutomesh® and compared with healthy (intact) control intestinal segments. At days 2, 7, 14, 30 and 90 following surgery, ileal and colonic mucosa were isolated from similar anastomized and control tracts and mounted in Ussing chambers containing Krebs oxygenated solution at pH 7.4. Electrophysiological parameters, i.e. short circuit current (Isc) and transepithelial resistance (Rt), as markers of mucosal function, were ...

A surgical instrument for performing an end-to-end anastomosis of first and second luminal structures includes a housing having an actuator attached thereto and a selectively removable loading unit attached to a distal end of the housing which supports any array of surgical fasteners at a distal end thereof. The surgical fasteners are simultaneously deformable upon activation of the actuator such that a distal end of each surgical fastener secures each end of each luminal structure to complete the end-to-end anastomosis wherein the resulting eversion is exterior to the luminal structures.

Next is a lecture series detailing the correct procedure for placement of an intracorporeal anastomosis, complete with CD-ROM demonstration, lecture, photo review, and a detailed explanation of the criteria for evaluation of an anastomosis. Once students have become familiar with the methodology, the real challenge begins. Participants are first separated into teams of two, and must cooperate in the placement of an anastomosis on inanimate tissue, which must have no less than eight interrupted sutures on the back wall and a running anastomosis on the front wall. Surgeons will then be instructed in Dr. Rosser s principles regarding optical correctness, port placement, and overall preparation. The participants must then perform the anastomosis on a section of pig bowel, which is much more difficult to work with than inanimate tissue. Once the anastomosis has been completed, it is then examined by instructors using strict grading criteria such as: proper length and depth, uniformity of sutures, ...

Results: After exclusion of 10 noninformative pregnancies, perinatal, double, and any survival rates were 61%, 44%, and 77%, respectively. When an anastomosis was detected at each of the 3 time points, perinatal and double survival rates were higher than when one was not (at first treatment, perinatal survival 83% versus 53%, respectively, P = .003; double survival 78% versus 33%, P , .001). Perinatal and double survival (P ,= .01) were poorer with more advanced stage, but any survival rates were not influenced by stage or anastomosis detection. Multiple logistic regression demonstrated that anastomosis detection at treatment increased the chance of perinatal (odds ratio [OR] 5.1, 95% confidence interval [CI] 1.6, 15.9) and double survival (OR 19.3, 95% CI 2.7, 138), independently of stage. For stages I-III at treatment, anastomosis detection predicted better perinatal (100% versus 63%, 100% versus 59%, and 83% versus 44%, respectively) and double survival rates (100% versus 52%, 100% versus ...

Of 2609 relevant studies, 16 randomized controlled trials (RCTs) met our inclusion criteria. Nine RCTs (n=473) compared straight coloanal anastomosis (SCA) to the colonic J pouch (CJP). Up to 18 months postoperatively, the CJP was superior to SCA in most studies in bowel frequency, urgency, fecal incontinence and use of antidiarrheal medication. There were too few patients with long-term bowel function outcomes to determine if this advantage continued after 18 months postop. Four RCTs (n=215) compared the side-to-end anastomosis (STE) to the CJP. These studies showed no difference in bowel function outcomes between these two techniques. Similarly, three RCTs (n=158) compared transverse coloplasty (TC) to CJP. Similarly, there were no differences in bowel function outcomes in these small studies. Overall, there were no significant differences in postoperative complications with any of the anastomotic strategies. ...

When a vein segment is grafted into arterial circulation, biomechanical forces stimulate modification of its structure. This morphological adaptive response is progressive during a medium or long term and occludes the vessel lumen, leading to a graft failure. The objective of this study was to characterize the early morphological response of the vascular wall in a terminal-terminal vascular vein graft model in Wistar rats. A segment of the femoral vein was placed in the femoral circulation. An end to end microsurgical graft anastomosis technique was implemented and standardized in twenty rats. The samples were processed with histological technique to analyze the overall structure with hematoxylin and eosin, the composition of the vessel wall with Masson trichrome technique, the proliferating and smooth muscle cells were detected with immunohistochemistry (anti-PCNA, anti-actin and anti CD68) and the induction of apoptosis with TUNEL technique. The times periods studied were 1, 3 and 5 days ...

Logistic regression was used in both univariate and multivariate modelling.. The team used the methods to identify independent preoperative variables associated with the presence of intraoperative leak.. Model parameters were estimated by the maximum likelihood method. From these estimates, odds ratios with 95% confidence intervals were computed.. The investigators found no postoperative anastomotic leaks or mortalities in these series.. Overall, endoscopic evaluation of the gastrojejunostomy resulted in the detection of 16% of intraoperative leaks.. The team noted a difference in the incidence of intraoperative leakage for patients, with 21% older than 40 years, and 10% in those younger than 40 years. In the initial 91 cases, the gastrojejunostomy was performed by the end-to-end anastomosis technique.. The team reported that the subsequent 249 were performed with a combination of linear stapling and handsewn technique. There was a non-significant trend to less leakage in 12% with end-to-end ...

A ring for use in anastomosis. Preferably, the ring is integrally formed from metal, and includes a ring portion and tines and docking members that extend from the ring portion. The ring portion and tines are malleable, and preferably also the docking members are malleable. The ring portion and tines are malleable in the sense that once deformed from a first shape into a second shape, they will not relax back into the first shape from the second. To install the ring in a vessel with the ring portion extending around an incision or other orifice, the tines pierce the tissue around the orifice and are curled against an anvil. The action of curling the tines inverts the tissue near the orifice edges to expose the inside surface of the vessel or organ. Other aspects of the invention are a method and apparatus for installing an anastomosis ring in an incision or other orifice in a vessel or other organ, a method and apparatus for precisely aligning two anastomosis rings (each installed in an incision or

The management of concomitant aortic and aortic valve disease with left ventricular assist device (LVAD) implantation for patients with severe cardiomyopathy is challenging, and has not been established given the complexity of LVAD surgery with concomitant aortic interventions. A 45-year-old patient presented to our institution with end-stage heart failure symptoms and non-ischemic cardiomyopathy. The patient was found to have a bicuspid aortic valve, severe native aortic regurgitation, a significant ascending aortic aneurysm, and severely depressed left ventricular (LV) function requiring two inotropes. He underwent a successful hemiarch repair of the ascending aortic aneurysm using a back table outflow graft anastomosis technique, and subsequent placement of a HeartWare Ventricular Assist Device (HVAD) with concomitant aortic valve closure with a modified Parks stitch. The patient did well postoperatively and is currently listed for heart transplantation.. ...

Postoperative anastomotic suture line complications, such as hemorrhage and pseudoaneurysm, are often encountered in thoracic aortic surgery. To minimize these complications different anastomotic techniques have been developed. We hereby describe a new distal anastomotic technique, which involves positioning the graft inside the aorta at the distal end, reinforcing the suture line with an externally placed Teflon felt strip, and finishing the anastomosis with a circumferential and continued suture technique called backstitch.

Background: Fibrin-based biological adhesives are used for tissue adhesion improving the outcome of gastrointestinal sutures. The objective was to assess the effectiveness of fibrin-based biological adhesives for prevention of anastomotic leakage in high-risk gastrointestinal anastomoses. Methods: A randomized clinical trial was designed to recruit patients underwent a rectal resection surgery. A subgroup of patients with rectal anastomosis were recruited from 2 different hospital centres. Patients in which a biological fibrin-based biological adhesive was applied to the suture line (study group) were compared versus a control group under standard practice. The main outcome measures was presence or absence of leakage and need for reoperation. Results: Thirty seven patients underwent a rectal resection and anastomosis. In 21 standard practice was applied and a fibrin-based adhesive was used in 16. Fourteen patients (37.8%) had a clinical or subclinical anastomotic leak, 11 belonging to control group

For patients with interrupted aortic arches, distal aortic arch dysplasia, long coarctation segments, or obvious vascular calcification and older children and adults, we adopted a Gore-Tex vascular graft bypass (Figure 1). First, we performed end-to-side anastomosis between the Gore-Tex vascular graft and normal descending aorta distal from the coarctation, and the anastomosis was continuously sutured with 5/0 prolene line, tightened and lined with strips of autologous pericardium. Next, we restored the cardiopulmonary bypass, allowed perfusion, and warmed up the blood. After expelling gas from the vascular graft and clamping the said graft, we performed end-to-side anastomosis between the Gore-Tex vascular graft and normal ascending aorta. We only performed end-to-side anastomosis between the vascular graft and normal descending aorta with circulatory arrest. This can decrease the total surgical time and facilitate good anastomosis. Lining with stripped autologous pericardium can prevent vessel ...

The purpose of this case report is to show how subtotal colectomy and anastomosis cecorectalis is the operation of choice. At the Childrens Hospital in Zagreb we have had only two cases on which we performed cecorectal anastomosis. The patients general condition and enormous dilatation of the ganglionic region indicated surgery and only anus praeter bipollaris was performed on the colon ascendens. The second operation took place one year after the first operation. At the second operation we performed subtotal colectomy with cecorectal anastomosis. The postoperative clinical course was without complications. The wound cured regularly. Digitorectal examination revealed no anomalies in the anastomosis. The children had 1-2 stools daily. After six months we performed a check up examination with irigography, ...

ASA 2018 Abstracts: Better Function With A Colonic J-pouch Or A Side-to-end Anastomosis? A Randomized Controlled Trial To Compare The Complications, Functional Outcome And Quality Of Life In Patients With Low Rectal Cancer After A J-pouch Or A Side-to- End Anastomosis

Fistula development after esophageal resection is considered as one of the most serious postoperative complications. The authors reported a case on clinical experiences in the postoperative diagnostic and successful therapeutic management of a tracheomediastinal fistula after esophageal resection, using endoscopic application of fibrin glue. The early approach of an anastomotic insufficiency after esophageal resection because of a squamous cell carcinoma (pT3pN0M0G2) below the tracheal bifurcation including transposition of a re-modelled gastric tube and end-to-side anastomosis 24 hours postoperatively in a 55-year old patient combined i) surgical re-intervention from the periesophageal site (reanastomosis, gastroplication, lavage, local and mediastinal drainage) and, later on, ii) extensive rinsing with consecutive endoscopic fibrin glue application into the tracheal mouth of the subsequently developed tracheomediastinal fistula as a consequence of the inflammatory changes within the ...

INTRODUCTION. In view of the high incidence of infection of the peritoneal cavity in surgical practice, many investigators have the relationship between peritonitis and healing of intestinal anastomoses. Contradictory results have been obtained in studies of the influence of infection on the development of colon anastomoses healing in experimental animals, with some investigators reporting high rates of dehiscense and mortality6,8,21 and others reporting little or no effect of infection on the anastomotic lesion12,18,20. Thus, the present study was conducted to determine the effect of peritonitis on the healing of experimentally induced colon anastomoses in rats.. METHOD. The study was conducted on 40 male rats (Rattus norvegicus albinus, Rodentia mammalia) of the Wistar-Tecpar strain aged 114 to 130 days and weighing on average 298 g. The animals were divided in two groups S (control) and P (experimental).. The animals were anesthetized with ether, weighed and identified. The ventral abdominal ...

1. (Science: anatomy) a vessel that directly interconnects an artery and a vein, and that acts as a shunt to bypass the capillary bed. Not to be confused with surgical anastomosis, nor with arteriovenous fistula. 2. (a) The direct or indirect connection of separate parts of a branching system to form a network, especially among blood vessels. (b) The surgical connection of separate or severed tubular hollow organs to form a continuous channel as between two parts of the intestine. 3. The connection of normally separate parts or spaces so they intercommunicate. An anastomosis may be naturally occurring or artificially constructed and be created during the process of embryonic development or by surgery, trauma or pathological means. An anastomosis may, for example, connect two blood vessels (as in a naturally occurring arteriovenous anastomosis, a connection between an artery and a vein) or it may connect the healthy sections of the colon or rectum after a cancerous or otherwise diseased portion ...

BACKGROUND: Revascularization of the posterior inferior cerebellar artery (PICA) is typically performed with the occipital artery (OA) as an extracranial donor. The p3 segment is the most accessible recipient site for OA-PICA bypass at its caudal loop inferior to the cerebellar tonsil, but this site may be absent or hidden due to a high-riding location. OBJECTIVE: To test our hypothesis that freeing p1 PICA from its origin, transposing the recipient into a shallower position, and performing OA-p1 PICA bypass with an end-to-end anastomosis would facilitate this bypass. METHODS: The OA was harvested, and a far lateral craniotomy was performed in 16 cadaveric specimens. PICA caliber and number of perforators were measured at p1 and p3 segments. OA-p3 PICA end-to-side and OA-p1 PICA end-to-end bypasses were compared. RESULTS: OA-p1 PICA bypass with end-to-end anastomosis was performed in 16 specimens; whereas, OA-p3 PICA bypass with end-to-side anastomosis was performed in 11. Mean distance from OA at the

Objective: due to the advantages of Laser Assisted Vascular Anastomosis (less occurrence of myointimal hyperplasia with better hemodynamic evolution, shorter surgical time, absence of diameter incompatibility, absence of anaphylaxis, easy execution) the evaluation of the ideal diode laser wavelength to perform anastomosis in elastic arteries, without solder, is a great advance in the surgical practice. Method: End-to-end anastomosis was performed on the common carotid arteries of swines, bilaterally, using diode lasers by the wavelengths: 808 nm (n=16), 980 nm (n=16), 1470 nm (n=16) and 1908 nm (n=16) with the same parameters (CW, spot size= 2mm, P≅ 5,1W, t=26s, E= 132,6J, I= 164,51 W/cm2, F= 4277,4 J/cm2). Following, the occurrence of bleeding was verified. When the anastomosis did not bleed a mechanical resistance test was performed. Results: In group 808 nm, there was no welding of the vessels. In group 1908 nm, carbonization of all arterial edges was observed. In groups 980 nm and 1470 nm, ...

Background: Antithrombin III is known as the most important natural inhibitor of thrombin activity and has been shown to attenuate local harmful effects of ischemia-reperfusion injury in many organs. In recent animal studies, delaying effect of remote organ ischemia-reperfusion injury on healing of intestinal anastomoses has been demonstrated. In this study, we investigated whether antithrombin III reduces deleterious systemic effects of ischemia-reperfusion injury on healing of colonic anastomoses in rats. ...

TY - JOUR. T1 - Impact of aberrant arterial anatomy and location of anastomosis on technical outcomes after liver transplantation. AU - Abouljoud, Marwan S.. AU - Kim, Dean Y.. AU - Yoshida, Atsushi.

N2 - Variations in donor and recipient arterial anatomy frequently present challenges for surgeons when attempting to establish proper arterial inflow during liver transplantation. We reviewed our data on 233 adult primary liver transplants, conducted from January 1996 through December 2001, to determine the impact of these variations on the outcomes after liver transplantation. Twenty-four (10.3%) arterial complications were encountered at a mean of 2.27 months after transplant. Carrel patches for the anastomoses were not used in 33 patients (14%), which had no relation to arterial complications (P = 0.7). Sixty-one donors (26.2%) had at ...

He was felt to be too high risk for surgery, and it was decided to attempt percutaneous angioplasty. A 4-F cut pigtail catheter and straight 0.035-inch wire was used to access the outflow cannula. Reference vessel diameter was 14 to 15 mm, and the region of stenosis was 8 to 9 mm in diameter (Fig. 4). An Amplatz 0.035-inch Super Stiff guidewire (St. Jude Medical, Golden Valley, Minnesota) was placed in the mid-cannula retrograde through the outflow graft, and a 14 mm × 4-cm Cordis Opta-Pro balloon angioplasty balloon (Cordis Corp., Miami, Florida) was inflated twice at the anastomosis to a maximal pressure of 4 atm. There was resolution of the waist narrowing with the second inflation (Figs. 5 and 6⇓⇓, Online Videos 1 and 2). During each inflation, HM2 flow was decreased transiently to 1 l/min for 3 to 4 s at a time. Post-angioplasty, Doppler flow velocity at the anastomosis improved from 1.9 m/s to 1 m/s. LVEDD decreased from 59 mm to 39 mm. The patient was discharged 4 days later, and HM2 ...

The use of intraoperative procedures to prevent dehiscence of the anastomosis, such as the addition of additional manual points, the mechanical suture and / or patches of collagen (reinforcement so called also buttressing) or sealants (fibrin or cyanoacrylate glues, such as Glubran® 2) is the rationale that led to the design of this study. Although today we have technologically advanced mechanical staplers, it is crucial to prevent anastomotic dehiscence. At the moment experimental results show that Glubran® 2 is a suitable potential reinforcement of intestinal anastomoses both manual and linear intracorporeal. Glubran 2 applied after the packaging of the mechanical anastomosis, polymerizes in a short time closing the micro spaces of the suture line between one point and the other, expressing an adhesive, hemostatic and sealant action on the tissues, creating an effective antiseptic barrier against the most common infectious agents or pathogens.. The aim of the study is to evaluate the ...

Materials and Methods: Forty male Sprague Dawley rats were randomly divided into 2 groups. Femoral artery anasto- mosis was performed in rats of the control group (n = 20) through heparinized serum (10 U/ml) irrigation. In the rats of the study group (n = 20), however, femoral artery anastomosis was performed through heparinized serum (10 U/ml)+0.5 cc bile irrigation. After the 1st week, anastomosis patency was evaluated with color duplex ultrasonography. A 1 cm segment of the femoral artery involving the anastomosis line was removed for histopathological evaluation ...

Doctors give unbiased, helpful information on indications, contra-indications, benefits, and complications: Dr. Nishi on colectomy lap anastomosis: There is an ileorectal anastomosis - when the colon is removed we can attach the ileum - part of the end of the small intestine - to the rectum. There is also an ileosigmoid anastomosis - when the ileum is attached to the sigmoid colon. Often the area is called the rectosigmoid region so this leads to the confusion. There is no ileorectal sigmoid anastomosis.

Nontraditional sites for vascular anastomoses to enable kidney transplantation in patients with major systemic venous thromboses.

A graft vessel preparation device and a method for using the graft vessel preparation device is provided. The graft vessel preparation device establishes and maintains a critical dimension on a graft vessel which corresponds to a dimension of an anastomosis site on a target vessel. One example of a graft vessel preparation device which prepares a graft vessel for a vascular anastomosis procedure includes a parallelogram linkage, a first spreader arm and a second spreader arm. The first spreader arm and the second spreader arm mount on opposing members of the parallelogram linkage in a parallel configuration. The spreader arms are configured in order to allow the placement of an end of a graft vessel over the spreader arms. The spreader arms are also configured to separate within an interior of the graft vessel once the graft vessel is placed over the spreader arms in order to establish a critical dimension. The critical dimension is established using a critical dimension locator. The critical dimension

Esophagogastric anastomosis in human surgery is part of the surgical treatment of esophageal cancer. Anastomotic leak is responsible for a third of all perioperative deaths. We suggest an enhanced healing of esophagogastric anastomosis, NO-system dependent, with stable gastric pentadecapeptide BPC 157. Throughout 4 days after esophagogastric anastomosis creation, rats received medication (/kg ip once daily: BPC 157 (10pg, 10ng), L-NAME (5mg), L-arginine (100mg) alone and/or combined). Daily assessment includes damage in stomach (sum of longest diameters, mm), esophagus (esophagitis, scored 0-4), anastomosis (ml H2O before leak), pressure in pyloric sphincter and in esophagus at anastomosis (cmH2O) and weight loss (g). In the control group we noted progressing stomach damage, severe esophagitis, rapid anastomosis leak, decrease of pressure, severe in pyloric sphincter as well as less pressure assessed in esophagus at anastomosis, alongside with prominent weight loss. By contrast, BPC 157 treated ...

Methods: Two patients, one with a congenital small bowel web, and one with a cecal mass are studied. The Gelpointtm System (Applied Medical, Rancho Santa Margarita, CA) is utilized for access. The congenital web is resected using endoscopic stapling devices, a stapled anastomosis is performed, and the common channel is closed with traction stitches and another firing of an endoscopic stapler. The cecal mass is resected via a right hemicolectomy, ileo-colic stapled anastomosis created, and closure of the common channel is accomplished with two layered running suture ...

Background: The aim of this study was to investigate patients with symptomatic anastomotic leakage diagnosed after hospital discharge. Methods: Patients undergoing low anterior resection of the rectum for cancer (n=234) who were included in a prospective multicenter trial (NCT 00636948) and who developed symptomatic anastomotic leakage diagnosed after hospital discharge (late leakage, LL; n=18) were identified. These patients were assessed in regard to patient characteristics, operative details, recovery on postoperative day five, length of hospital stay, and how the leakage was diagnosed. A comparison with those who did not develop symptomatic leakage (no leakage, NL; n=189) was performed. Minimum follow up was 24 months. Results: Median age was 69 years, 61% were females, and 6% had UICC cancer stage IV in LL. On postoperative day 5, LL had a postoperative course similar to NL in regard to morning temperature, per oral intake and bowel activity. The proportion of patients being on antibiotic ...

PURPOSE: Colon anastomotic leakage remains a serious and common surgical complication. Animal models are valuable to determine the pathophysiological mechanisms and to evaluate possible methods of prevention. The aim of this study was to develop an optimal model of clinical colon anastomotic leakage in a technically insufficient anastomosis in the mouse. METHODS: A total of 110 mice were used in three pilot studies (1-3) and two experiments (A, B). Due to the high complication rates, the analgesic regimen and surgical techniques were changed throughout the pilot studies/experiments. In the final successful experiment (B), eight and four absorbable sutures were used in the control and intervention anastomoses, respectively, and buprenorphine in chocolate spread was used for pain treatment. RESULTS: In the final model (experiment B), significantly more animals in the intervention group had clinical anastomotic leakage compared with controls (40 vs. 0 %, p = 0.003). The weight loss was greater and ...

A medical device which can be implanted at a target site in a living body. The device includes an inner flange formed by radial expansion of the device and an outer flange formed by axial compression of the device. The device can include an implant portion and a discard portion which separate from each other during formation of the outer flange. The separation can occur by fracturing a frangible linkage or by mechanically separating a portion of the outer flange from a deployment tool. The device can be a one piece anastomosis device for connecting a graft vessel to a target vessel without the use of conventional sutures. The inner and outer flanges capture the edges of an opening in a target vessel and secure the graft vessel to the opening in the target vessel. The device greatly increases the speed with which anastomosis can be performed over known suturing methods.

The authors present a novel synthetic vascular model for microanastomosis training. This model is suitable for trainees with intermediate level of microsurgical skills, and useful as a bridging model between simple suturing exercise and in vivo rat vessel anastomosis during pre-clinical training.

The CycloneTM System (Castlewood Surgical, Inc., Concord, MA) is a novel device that facilitates the attachment of the saphenous vein onto the ascending aorta for the purpose of creating a bypass graft during a coronary artery bypass grafting (CABG) operation. It allows the surgeon to perform a hand-sewn anastomosis with no disruption of the intima of the aorta, and no need for partial clamping. During a 36-month period 109 CABG operations were performed, and the CycloneTM System (and its predecessor, the HexalonTM) was utilized to create 138 proximal anastomoses. This study demonstrates that this is a safe and effective method of creating a clampless, no-touch proximal anastomoses during off-pump CABG.

Two Kelly clamps are placed over a section of mesentery, and the section is divided with a knife or cautery pencil between the two clamps; then it is ligated. This process is continued, until the diseased portion and the anastomosis site have been isolated ...

The gastric pouch-jejunal limb anastomosis is usually done by circular staple in our institute. We use the instruments from commercial PEG set to facilitate the procedure. Under direct vision from the endoscope inside the pouch, The tiny hole is create by cautery from outside. The snare is passed through this hole into peritoneal cavity to retrieve the nilon loop which insert via the laparoscopic port. After the loop is bought out from the patients mouth, the anvil of the staple is fixed to this loop. The loop is drawn backward, so the anvil is introduced into the gastric pouch. The EEA staple shaft is inserted into peritoneal cavity via the extended port incision. The anvil is attached and approximated to the shaft, then the staple is fired. The completeness of the anastomosis is ensured.. Conclusion ...

The impact of donor arterial variations and their management was investigated retrospectively in 527 consecutive allografts. Anomalous arteries were found in 161 grafts (30.6 per cent). There was no significant difference in the overall incidence of arterial complications between grafts with normal (3.6 per cent) and abnormal (5.6 per cent) anatomy. However, there was a higher incidence of arterial complications in transplants requiring multiple arterial anastomoses (P = 0.02), or anastomosis of donor vessels to recipient aorta with (P = 0.0003) or without (P = 0.04) an interposition graft for arterial reconstruction. The incidence of biliary complications was similar in grafts with a normal (18.8 per cent) or anomalous (18.0 per cent) arterial supply. Anomalies of hepatic arterial anatomy occur in one-third of all livers and do not compromise graft outcome unless multiple anastomoses or direct anastomosis to the recipient aorta are required for arterial reconstruction.

Considering the fact that hemodynamics plays an important role in the patency and overall performance of implanted bypass grafts, this work presents a numerical investigation of pulsatile non-Newtonian blood flow in three different patient-specific aorto-coronary bypasses. The three bypass models are distinguished from each other by the number of distal side-to-side and end-to-side anastomoses and denoted as single, double and triple bypasses. The mathematical model in the form of time-dependent nonlinear system of incompressible Navier?Stokes equations is coupled with the Carreau?Yasuda model describing the shear-thinning property of human blood and numerically solved using the principle of the SIMPLE algorithm and cell-centred finite volume method formulated for hybrid unstructured tetrahedral grids. The numerical results computed for non-Newtonian and Newtonian blood flow in the three aorto-coronary bypasses are compared and analysed with emphasis placed on the distribution of cycle-averaged ...
