PURPOSE
Currently, there are two laparoscopic stapling techniques to perform the gastrojejunostomy in gastric bypass surgery: the linear stapling and circular stapling techniques. The aim of the study was to compare the two techniques regarding postoperative morbidity and weight loss at an accredited bariatric reference center in Switzerland.
METHODS
We compared two consecutive cohorts at a single institution between November 2012 and June 2014 undergoing laparoscopic gastric bypass surgery. The frequency of complications and weight loss at 1 year was assessed in 109 patients with the 21-mm circular stapling technique (CSA) and 134 patients with the linear stapling technique (LSA).
RESULTS
Postoperative complications were more frequent in the CSA group with 23.9 versus 4.5% in the LSA group (p = <0.0001). The main difference was the frequency of strictures, which occurred in 15.6% in the CSA group versus 0% in the LSA group. As a result, endoscopic dilation was required at least once in 15 patients. There was no statistically significant difference in percentage of excessive weight loss (EWL) in both groups; EWL was 74% in the CSA group and 73% in the LSA group (p = 0.68).
CONCLUSION
Linear stapled laparoscopic gastric bypass had fewer stenotic strictures with similar weight loss at 1 year compared to circular stapling technique.
