Preoperative upper endoscopy is useful before revisional bariatric surgery.
OBJECTIVE
We hypothesized that patients who have previously had bariatric surgery and are undergoing revision to laparoscopic Roux-en-Y gastric bypass would have abnormal findings detected by upper endoscopy that could potentially influence patient management. The procedures that are being revised include vertical banded gastroplasty, laparoscopic adjustable gastric bands, nonadjustable gastric bands and previous Roux-en-Y gastric bypass (open and laparoscopic).


METHODS
We conducted a retrospective chart review of patients who previously had undergone vertical banded gastroplasty or nonadjustable gastric banding. We preoperatively performed an upper endoscopy on all patients. The endoscopy reports were reviewed and the findings entered into a database.


RESULTS
Eighty-five percent of 46 patients undergoing revisional bariatric surgery had an abnormal upper endoscopy. Eleven percent had a gastrogastric fistula. Gastritis and esophagitis were noted in 65% and 37%, respectively. Eleven percent of patients had band erosion, 2 from a nonadjustable band, and 5 from vertical banded gastroplasties. Based on our findings, 65% of our patients required medical treatment.


CONCLUSIONS
Preoperative upper endoscopy provides valuable information before revisional laparoscopic bariatric surgery. In addition to identifying patients who need preoperative medications, the preoperative upper endoscopy also provided valuable information regarding pouch size and anatomy. Preoperative upper endoscopy should be performed by the operating surgeon on every patient undergoing revisional bariatric surgery.
