Filter by:LifeSeal™ Kit, surgical sealant designed for staple-line reinforcement that is applied over the anastomotic line to prevent bowel content leakage until full physiological function is restored. RATIONALE : Postoperative anastomotic leakage is one of the most devastating and feared complications in colorectal surgery. The risk of postoperative anastomotic leakage varies widely depending on the level of anastomosis while the risk is higher in low anastomosis. In order to best demonstrate the benefits of LifeSeal™ in providing staple line reinforcement and helping to reduce leaks, the study includes high risk anastomoses, defined as colorectal and coloanal anastomoses performed within 10 cm from the anal verge. STUDY DESIGN: This study is designed as a prospective, multi-center, multinational randomized, single-blind, double armed study PRIMARY OBJECTIVE: The primary objective of this study is to assess the efficacy and safety of LifeSeal™ Kit as measured by the change in overall anastomotic leak rates in subjects undergoing low anterior resection with an anastomosis below 10 cm from the anal verge, over the first 17 weeks after surgery. SECONDARY OBJECTIVES: The secondary objective of this study is to assess the incidence of post-operative leaks and additional benefits that could be related to the use of LifeSeal™ Kit such as reducing the severity and improving the outcome of a leak once it has occurred. In addition, the study will allow for collection and analysis of additional safety data and usability assessment of the device, medical resource utilization, and health related quality of life measures.
The purpose of this study is to evaluate the effectiveness of transanual tube placement in low anterior resection (LAR) for rectal cancer in preventing anastomotic leakage.
This study will assess the effectiveness of commercially available LifeSeal® Kit as measured by the incidence of post-operative clinical anastomotic leak rates in subjects undergoing low and ultralow anterior resection with an anastomosis. All patients treated with LifeSeal® will be offered to participate
The technique the investigators propose to perform colorectal and colo-anal anastomosis in patients underwent low and ultra-low anterior resection for rectal cancer could potentially reduce the anastomotic leakage rate by better trans-anal introduction of the circular stapler, elimination of the previous suture lines and dog ears, combined with direct inspection of the anastomosis, easy performance of trans-anal air leak tests and eventually direct repair of any small anastomotic defects. Another important point in cancer surgery is the easily identification of the distal margin. In fact, this technique is simple to perform, reproducible and safe in terms of complications.
The study evaluates the feasibility and advantage of modified laparoscopic double-staple anastomosis technique which to eliminate the 'dog ears' in laparoscopic rectal anterior resection.
Anastomotic leak (AL) is a breakdown of a suture line in a surgical anastomosis with a subsequent leakage of the luminal content. Anastomotic leakage occurs commonly in rectal and esophageal anastomosis than the other parts of the alimentary tract due to technical difficulties in accessing these areas and their easily compromised blood supply. Anastomotic leakage is the most feared complication following rectal resection and anastomosis. The incidence of anastomotic leakage ranges from 2.8% to more than 15%, with mortality rate more than 30%. Subclinical anastomotic failure may occur in up to 51% of patients. Anastomotic leakage leads to increase the rate of secondary interventions, re-operations, longer postoperative hospital stay, increased cost, and major impact on the patient's quality of life. In the medium to long term, patient may be unfit for post-operative adjuvant therapy with decreased the disease survival. Furthermore anastomotic leakage itself may increase the local recurrence, a reduction in overall survival, and a large proportion of patients are left with a permanent stoma.
Gastric conduit ischemia or anastomotic breakdown after esophagectomy with cervical esophagogastrostomy often cause severe complications, such as leakage, necrotic organs, and strictures. Thus, the purpose of this study is the safety and efficacy of endoscopic evaluation about reconstructive organs after esophagectomy. The investigators evaluate endoscopic predictions using classifications in acute phase after esophagogastrostomy.
The rate of anastomotic leakage after laparoscopic anterior resection（LAR） for medium & low rectal cancer is still high. the transanal drainage tube (TDT) was thought to be useful for deduce the rate. There were several studies, but most of them were not randomized controlled trial (RCT) studies. There was only one RCT study with enough samples, but it was designed for open anterior resection, and the patients underwent diverting stoma were excluded, so there was the selection bias. LAR now is thought to been with the same effect, and it is safe and feasible. So a RCT investigation for the use of TDT for prevention of anastomotic leakage after LAR for medium & low rectal cancer is needed.
Rationale: The surgical complication of intestinal anastomotic leak remains a clear and present danger to patients despite advances in surgical technique and ever more powerful antibiotics. No surgeon is immune from this complication and leak rates have not changed in decades. The consequences of a leak (peritonitis, sepsis, death) can be so severe that in the case of rectal cancer, diverting ileostomies are routinely performed to divert the fecal stream away from the healing anastomosis. We have recently discovered that certain intestinal bacteria, with the capacity to express collagenase and cleave MMP9 (Matrix metallopeptidase 9) to its active collagen degrading form, play a key and causative role in anastomotic leak. These bacteria often escape elimination due to the failure of current antibiotic regimens and their delivery methods to remain functionally durable at anastomotic tissue sites. Purpose: This phase II clinical trial will track, in real time, the process of anastomotic healing and its associated microbiome by performing serial endoscopic surveillance (SES) following rectal cancer resection. By capturing anastomotic images and the associated microbial and inflammatory mediators from anastomotic fluids via SES performed at three time points following rectal cancer resection, we will correlate healing to microbial composition and inflammatory mediator status. Patients will be randomized and, at each time point, will receive lavage of their anastomosis with either saline or a triple antibiotic solution (ciprofloxacin, metronidazole, neomycin). An anastomotic healing score captured during SES will be compared between the two treatment arms and correlated to microbial and inflammatory mediator analyses of fluid samples to determine how intestinal microbes influence the process of anastomotic healing.
The aim of this study was to evaluate the impact of fluorescence imaging on the location of colorectal transection lines based on evaluation of perfusion with indocyanine green, how it's going to affect surgical planning and its possible benefits in reducing anastomotic leakage.
