Brief Summary

Staple-line leak is the most frequent and incapacitating complication after laparoscopic sleeve gastrectomy (LSG). The aim of this prospective randomized trial is to compare the staple-line leak rate after LSG according to the use of a standard bougie calibre (34, 36 or 38 Fr) or 48-Fr, assuming that a higher diameter is correlated with a lower risk of leak, without lowering long-term weight loss.
