Anatomic findings and outcomes after antireflux procedures in morbidly obese patients undergoing laparoscopic conversion to Roux-en-Y gastric bypass

Laparoscopic conversion of Nissen fundoplication to Roux-en-Y gastric bypass is a feasible salvage operation for recurrent gastroesophageal reflux disease in the morbidly obese. The incidence of wrap disruption appears to be relatively high and the incidence of intact wrap herniation low in obese patients after failed Nissen fundoplication, suggesting that the mechanism of failure after primary antireflux surgery in obese patients may be different than that in normal-weight patients.
