Introduction:
Intraluminal staplers for gastrojejunostomy construction during Roux-en-Y gastric bypass (RYGBP) may be associated with postoperative strictures. We analyzed outcomes of a transabdominal circular-stapled RYGBP with evaluation of short- and long-term anastomotic complications.
Methods:
All laparoscopic RYGBPs performed between January 2004 and December 2005 at an academic institution were reviewed. The gastrojejunostomy was created by using the transabdominal passage of a 21-mm intraluminal circular stapler into an antecolic, antegastric Roux limb. This retrospective chart review analyzes patient demographics, anastomotic complications, and weight loss.
Results:
Between January 2004 and December 2005, 159 patients underwent transabdominal circular-stapled RYGBP. Fifteen patients developed a stenosis at the gastrojejunostomy, all requiring endoscopic balloon dilatation. One of these patients required laparoscopic revision of the gastrojejunostomy. Eleven strictures occurred after 30 days, whereas only 4 strictures occurred within 30 days of surgery. Two marginal ulcerations were seen within 1 year of surgery.
Conclusion:
Our 9.4% stricture rate parallels what has been reported in the literature. The majority of strictures were amenable to one endoscopic treatment session. Transabdominal circular-stapled gastrojejunostomy is a reproducible construct for use in bariatric surgery.

Esophageal Strictures-I: Introduction
Etiology
The primary cause of esophageal strictures is long-standing gastroesophageal reflux disease (GERD), accounting for about 70 to 80% of adult cases. Chronic acid reflux can lead to injury and scarring of the esophageal lining, culminating in...
