Background: Previously we have reported variation in pre-operative clinical characteristics between women and men undergoing laparoscopic roux-en-Y gastric bypass (LRYGB). However, variation by sex in post-operative outcomes following LRYGB has not been investigated.
Methods: Pre-operative data was compared to follow-up data at 12 months after surgery on 83,059 patients from the Surgical Review Corporation's BOLD database.
