Clinical significance of upper gastrointestinal endoscopy before laparoscopic bariatric procedures in Japanese patients

The choice between performing routine and selective upper gastrointestinal endoscopy (UGE) before bariatric surgery remains controversial. This study aimed to evaluate the clinical significance of UGE before laparoscopic bariatric procedures.
We enrolled 155 obese Japanese patients who underwent laparoscopic bariatric procedures at our institute and evaluated their endoscopic findings, such as reflux esophagitis (RE), hiatal hernia (HH), Barrett’s esophagus, gastritis, duodenitis, gastroduodenal ulcer, gastric cancer, and polyps.
Preoperative endoscopy revealed abnormal findings in 102 patients (66%), including gastritis in 57 (37%), HH in 51 (32%), RE in 27 (17%), benign gastric polyps in 16 (10%), duodenitis in 6 (4%), and Barrett’s esophagus in 1 (0.6%). Two patients with definite HH were treated with simultaneous crural repair at the time of bariatric surgery. Duodenitis was graded as severe in three of these six patients and treated with a proton pump inhibitor before surgery. Eleven patients received therapy to eradicate Helicobacter pylori (H. pylori), either before or after the surgery. In summary, preoperative endoscopy changed the perioperative management for 16 of the 155 patients (10%).
Routine UGE may be necessary before bariatric procedures in obese Japanese patients.
