Intra-operative pneumothorax complicating laparoscopic Roux-en-Y gastric bypass.

Background: Intra-operative pneumothorax (PTX) is an infrequent complication of laparoscopic surgery. Most cases are attributed to CO(2) diffusion across congenital diaphragmatic defects and resolve spontaneously. We report a case of PTX during a laparoscopic Roux-en-Y gastric bypass (LRYGBP).
