简要总结

Background

Excess weight and obesity is the fifth leading risk factor for global death. Bariatric surgery is considered as the only effective long-term treatment for morbid obesity. Laparoscopic Roux-en-Y gastric bypass is one of the best surgical procedures, since it achieves excellent long-term results with a low complication rate. Intestinal anastomosis is a very complex and time-consuming procedure in laparoscopy, mainly due to the difficulties of knotting the suture in a limited working area. Barbed sutures may enhance this procedure by eliminating the need for knot tying.

Objective The aim of this study is to compare the safety and efficacy of knotless barbed sutures (Stratafix) and continuous sutures (Vicryl) for closing the gastrojejunal and jejunojejunal anastomosis in obese patients undergoing gastric bypass.

Study design

This is a prospective randomized study. Patients will be randomly assigned to one of two groups: traditional suture group or knotless suture group. Randomization will be realized by sealed envelopes according to a computer-generated sequence of random numbers, which will be opened for the surgeon just before starting the anastomosis. During the surgery the gastrojejunal and jejunojejunal anastomoses will be performed with a stapler (Echelon 45 Endopath) and closed with a traditional (Vicryl) or knotless (Stratafix Unidirectional) suture. The same surgeon, experienced and specialized in laparoscopic gastric bypass technique, will perform all procedures.

Study population

Two hundred patients undergoing laparoscopic Roux-en-Y gastric bypass.

Main study parameters/endpoints

The primary outcome measure will be the rate of anastomosis-related complications (leakage, bleeding, gastric fistula, anastomotic stenosis) at 4 weeks and at 6 months post-op (safety). The secondary outcome measure will be the time spent on closing the gastrojejunal and jejunojejunal anastomosis (efficacy).

  1. INTRODUCTION AND RATIONALE

Obesity

Excess weight and obesity is the fifth leading risk factor for global death (WHO 2011). It has been demonstrated that conservative treatment of obesity, such as restricting calorie intake, increasing physical activity, and medical treatment, did not succeed in achieving significant long-lasting loss of weight (Flegal 2002). Therefore, bariatric surgery is considered as the only effective long-term treatment for morbid obesity to achieve substantial and sustainable weight loss (Fisher 2002).

Gastric bypass

Gastric bypass has a two-way effect: it restricts how much food the stomach can hold (restrictive) and it affects how food and calories are absorbed into the bloodstream (malabsorptive). This combination surgery has the highest success rate for amount of weight loss. Laparoscopic Roux-en-Y gastric bypass is one of the best surgical procedures, since it achieves excellent long-term results with a low complication rate (Schauer 2003, Suter 2011, Fisher 2002). During this procedure two anastomoses - gastrojejunal and jejunojejunal -are constructed. This can be achieved with handsewn suturing or with mechanical stapling (Gonzalez 2003). If the anastomoses are stapled with a linear technique, closing of the enterotomies with sutures is still required. This is a very complex and time-consuming procedure in laparoscopy, mainly due to the difficulties of knotting the suture in a limited working area (De Blasi 2013).
