Routine esophagogastroduodenoscopy (EGD) before bariatric surgery remains controversial. This study was undertaken to determine the feasibility, safety, and effectiveness of routine intraoperative esophagogastroduodenoscopy (EGD) before bariatric surgery, the incidence of pathological EGD findings in patients undergoing bariatric surgery, the incidence of altered surgical plans because of the EGD findings, and to correlate patient symptoms with the EGD findings.


This is a Prospective ongoing, interventional study that was started on March 1st, 2018 with this preliminary report covering the cases up to September 30th, 2019. Routine intraoperative pre-bariatric procedure EGD was done and findings recorded. Patients consented for the endoscopy and the possibility of altering the planned operation was discussed with the patient.


Routine intraoperative EGD was done on 1727 patients. Nine hundred twenty-two (53.4%) were female. Three hundred fifty-one (20.3%) patients had preoperative history of or symptoms of gastroesophageal reflux disease out of which 84(29%) had positive findings on endoscopy. One hundred twenty (6.9%) had esophagitis and only 22(18.3%) had symptoms of gastroesophageal reflux disease (GERD) preoperatively. Two hundred ninety (16.7%) had gastritis, 392(22.3%) had bile in stomach, 105(6.07%) had duodenitis and 50 (2.9%) had a hiatus hernia. Our primary plan of surgery was changed based on endoscopic findings in 47(2.7%) of patients.


Intraoperative EGD is do-able, cost-effective, safe and convenient for both the patient and surgeon. We found asymptomatic significant upper gastrointestinal (UGI) pathologies that altered the planned procedure in 2.7% of the patients.
