Filter by:The primary aim of this trial is to rigorously evaluate the comparative benefits and potential risks associated with Billroth II reconstruction with Braun anastomosis versus Billroth II reconstruction alone following distal gastrectomy with D2 lymphadenectomy in patients diagnosed with gastric cancer. This assessment focuses on delineating the therapeutic efficacy, safety profile, and overall clinical outcomes of these two surgical approaches in treating this condition.
The efficacy of three different reconstruction methods after proximal gastrectomy will be investigated in this study through a prospective, multicenter, randomized controlled trial.
Obesity has become an important medical and social problem in western countries today. Roux-en-Y gastric bypass (LRYGB) is the most commonly performed surgery for the treatment of morbid obesity in the United States. Recently, there has been a steady increase in the number of surgeons performing bariatric surgery. In 2008, approximately 344,000 bariatric procedures were performed worldwide, of which 220,000 were performed in the United States and Canada. Most of these surgeries were laparoscopic gastric bypass procedures. There are many technical variations in the performance of the Roux-en-Y gastric bypass, especially when the approach is laparoscopic. Three techniques are commonly used when creating a gastrojejunostomy (GJ): hand-sewn, linear-staple, and circular-staple approaches. The effect of larger-caliber gastrojejunostomy on long-term weight loss is worrisome. Numerous recent reports describe the relationship between gastrojejunostomy enlargement and weight gain after gastric bypass, suggesting that this is a potentially valid concern. In this study, we aim to determine the effect of this potential GJ enlargement on weight loss.
A leak from a colorectal anastomosis is a post-operative complication surgeons fear the most, following colonic resection. Over the years, there have been multiple suggestions for intraoperative tests for the integrity of the colorectal anastomosis. Two of the most common tests that are performed routinely are: 1. Air tight leak test - filling the pelvis with saline and insufflating air trans anal - looking for air bubbles in the saline filled pelvis. 2. Injecting diluted dye (methylene blue) trans anal, and looking for blue dye stains on gauze pads covering the outer side of anastomosis. The aim of the study is to compare the two methods, and to assess if there is a superior method. A secondary aim is to establish standards to perform the test, mainly to assess the appropriate pressure to apply on the anastomosis. In this prospective study patients scheduled to undergo colonic resection of their distal part of the colon/ rectum with colorectal anastomosis, will have both testing methods performed sequentially and will be followed post-operative to assess the yield and sensitivity of the testing methods.
