Abstract
Background
Roux-en-Y gastric bypass (RYGB) effectively treats obesity and gastroesophageal reflux disease (GERD). As more surgeons recommend RYGB to treat GERD in patients with obesity, there are concerns about this approach in patients with previous non-bariatric foregut surgery. This study aims to evaluate the effect of previous non-bariatric foregut surgery on subsequent RYGB.
Methods
Retrospective review of 2089 patients undergoing RYGB between January 1985 and June 2015 was conducted to identify all patients with previous non-bariatric foregut surgery. Perioperative and postoperative data was collected by retrospective chart review.
Results
A total of 11 patients with prior non-bariatric foregut surgery underwent RYGB with median time between operations of 95.6 months. Of note, 7/11 (63.6%) had previous Nissen fundoplication. Conversion to open operation was required in 3/7 (42.9%) with previous Nissen compared to 1/4 (25%) in those without previous Nissen. The average length of stay (LOS) was 3.9 ± 0.9 days, significantly longer than our institutional average for RYGB of 3.2 ± 3.2 days (p = 0.02). Mean percentage of excess body mass index loss (%EBMIL) was 64.7 ± 23.5 at 4-year median follow-up, comparable to our institution’s previously reported data. No mortalities were attributed to RYGB and the overall complication rate was 18.2%, compared to our institutional complication rate for RYGB of 8.5% (p = 0.253).
Conclusion
Despite increased technical difficulty and increase perioperative morbidity, patients undergoing RYGB with previous non-bariatric foregut surgery had long-term symptom resolution and robust weight loss. This indicates that in the right hands, RYGB after non-bariatric foregut surgery may be performed safely and effectively.
