Gastrojejunal strictures after Roux-en-Y gastric bypass with a 21-MM circular stapler

Area of Science:

• Bariatric surgery outcomes
• Surgical technique analysis
• Gastrointestinal surgery complications

Background:

• Postoperative strictures are a known risk of intraluminal staplers used in gastrojejunostomy during Roux-en-Y gastric bypass (RYGBP).
• This study evaluates the outcomes of transabdominal circular-stapled RYGBP, focusing on anastomotic complications.

Purpose of the Study:

• To analyze the short- and long-term anastomotic complications associated with transabdominal circular-stapled gastrojejunostomy in RYGBP.
• To assess the efficacy of endoscopic treatment for resulting strictures.

Main Methods:

• Retrospective review of 159 laparoscopic RYGBPs performed between January 2004 and December 2005.
• Gastrojejunostomy created using a 21-mm intraluminal circular stapler via transabdominal passage.
• Analysis of patient demographics, anastomotic complications, and weight loss.

Main Results:

• Fifteen patients (9.4%) developed gastrojejunostomy stenosis, all requiring endoscopic balloon dilatation.
• Eleven strictures occurred post-30 days, and 4 occurred within 30 days.
• Two marginal ulcerations were observed within one year; one patient needed laparoscopic revision.

Conclusions:

• The 9.4% stricture rate is consistent with existing literature on RYGBP.
• Transabdominal circular-stapled gastrojejunostomy is a reproducible and effective technique in bariatric surgery.
• Endoscopic balloon dilatation is a successful primary treatment for most strictures.
