A 30 mm sized gastrojejunostomy may lead to a lower rate of therapy failure in comparison to a 45 mm sized gastrojejunostomy following laparoscopic Roux-en-Y gastric bypass.

ABSTRACT:

Background

In bariatric surgery the laparoscopic Roux-en-Y gastric bypass (LRYGB) has been proven to be a safe and effective approach. Currently the optimal size of the linear-stapled gastrojejunostomy (GJ) and its impact on weight loss are not known due to a lack of clinical trials on that topic. We aimed to provide evidence on the impact of the GJ size in terms of gastric bypass weight loss.

Methods

Patients who underwent LRYGB due to morbid obesity were retrospectively analyzed from January 2013 to January 2016. While the procedure was completely standardized, one surgeon continued using the 45 mm sized linear stapler to perform GJ while the other switched to using a 30 mm cartridge.

Results

277 patients were female (78%) and 77 males. The average age was 41.7 ± 12
