Value of preoperative upper endoscopy in patients undergoing laparoscopic gastric bypass.
BACKGROUND
Preoperative evaluation of patients undergoing laparoscopic Roux-en-Y gastric bypass (LRYGBP) has included esophagogastroduodenoscopy (EGD) with little data to substantiate its use.


METHODS
A retrospective analysis was conducted of patients from Feb 04 to Mar 05 who underwent preoperative EGD and subsequently LRYGBP.


RESULTS
169 patients underwent EGD prior to surgery. Their mean age was 41.1 years (range 14-66), mean BMI 49.7 (range 35-78), and 82% were females. There were no complications from EGD. Significant findings in patients at EGD included gastric ulceration in 3 (2%), duodenal ulcer in 1 (0.7%), Barrett's esophagus in 2 (1.3%), and a GI stromal tumor (GIST) in 1 (0.7%). EGD revealed hiatal hernias in 56 (35.2%), esophagitis in 28 (17%), Schatzki's ring in 5 (3%), gastritis in 43 (27%), gastric polyps in 8 (5%), and duodenitis in 9 (6%). 53 patients (33.3%) had a negative EGD. Ulcer and severe gastritis, esophagitis, and duodenitis diagnosed preoperatively were treated medically before surgery. 9 hiatal hernias were repaired intraoperatively. The patient with the GIST underwent laparoscopic near-total gastrectomy and gastric bypass, while 1 patient with an antral polyp underwent laparoscopic partial gastrectomy in addition to the LRYGBP.


CONCLUSIONS
EGD is essential for diagnosis of GI diseases including tumors, ulcers, and hiatal hernias that alter the medical and surgical management of patients undergoing gastric bypass.
