Background

The aims of this study were to determine the rate of gastrojejunostomy (GJ) stricture following Roux-en-Y gastric bypass (RYGBP), the independent predictors of stricture, and clinical outcomes with and without a stricture.

Methods

Univariate and multivariate analysis of peri-operative and outcomes data were prospectively collected from 379 morbidly obese patients who underwent consecutive open or laparoscopic RYGBP from January 2003 to August 2006. Predictors studied were age, gender, BMI, co-morbidities, surgical technique (hand-sewn vs linear stapler vs 21-mm vs 25-mm circular stapler; open vs laparoscopic; retrocolic retrogastric vs antecolic antegastric Roux limb course, and Roux limb length), and surgeon experience. Outcomes studied consisted of occurrence of GJ strictures, technical details and outcomes after endoscopic therapy, and excess weight loss (EWL) at 12 months.

Results

15 patients (4.1%) developed a GJ stricture. The use of a 21-mm circular stapler was identified as the only independent predictor of a GJ stricture (odds ratio 11.3; 95% CI 2.2-57.4, P = 0.004). Endoscopic dilation relieved stricture symptoms in all patients (60% one dilation only). There was no significant difference in %EWL at 12 months between the patients with a stricture (median EWL 54%, IQR 49 – 63) vs those without a stricture (median EWL 61%, IQR 49-73, P = 0.33).

Conclusion

The rate of GJ strictures is 4.1%. The use of a 21-mm circular stapler is the only independent predictor of GJ stricture. Endoscopic dilation relieved symptoms in all patients.Weight loss is independent of the anastomotic technique used and occurrence of a GJ stricture.
