Abstract

BACKGROUND:

To report the anatomic findings and outcomes in patients undergoing laparoscopic takedown of Nissen fundoplication with conversion to Roux-en-Y gastric bypass.

METHODS:

We reviewed the records of patients who underwent laparoscopic Nissen takedown with conversion to Roux-en-Y gastric bypass from January 2001 to April 2006 at the University of Minnesota Medical Center.

RESULTS:

Eleven patients were identified. Nine patients had gastroesophageal reflux disease preoperatively, of whom six underwent 24-hour pH monitoring. In 2 patients, the pH study findings were negative. Eight prior procedures had been performed laparoscopically. Eight patients were women. The mean age was 44 years. The average body mass index preoperatively was 44 kg/m(2) (range 35-61). The mean follow-up was 13.8 months (range 4-39). The body mass index at follow-up was 30.2 kg/m(2). The operative time was 349 minutes (range 222-624). The hospital length of stay was 3.4 days (range 2-6). No conversions to open surgery were required. No major short-term complications developed. Minor complications included wound or drain site infection in 3 patients, with abscess in 2, pressure sore of the lateral aspect of the foot in 1, pneumonia in 2, and marginal ulcer in 2 patients. No strictures were observed. One internal hernia occurred. Of the 9 patients with gastroesophageal reflux disease preoperatively, all had 100% improvement in symptoms, with complete resolution in 7 (78%). Wrap disruption was present in 5 (45%) of 11 patients. Herniation of an intact wrap had occurred in 1 patient. One patient had both herniation and wrap disruption.

CONCLUSION:

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.
