Preoperative esophagogastroduodenoscopy findings and effects on laparoscopic Roux-en-Y gastric bypass in area with high prevalence of Helicobacter pylori infection: multi-center experience in Iran
The current study aimed to evaluate EGD findings effects on laparoscopic Roux-en-Y gastric bypass (RYGB) plan and time in areas with a high prevalence of Helicobacter pylori infection.
Esophagogastroduodenoscopy (EGD) and Helicobacter pylori testing are routine parts of preoperative assessment of bariatric surgery at many centers
This was a cross-sectional study of all patients underwent EGD and histopathological examination before laparoscopic RYGB in three gastroenterology centers in Iran between January 2018 and December 2020.
Results:
In total, 637 patients (52.4% female) were enrolled, of which 46.8% had no abnormal mucosal appearance. In 1.7%, surgery was canceled (gastric adenocarcinoma, gastric intestinal metaplasia, GIST, and esophageal varices). The prevalence of H. pylori was 61.5%, and there was no statistical difference between groups of normal and abnormal EGD; however, surgery was postponed after H. pylori eradication in both groups. Overall, 44.4% of patients with esophagitis (any grade), peptic ulcer disease, erosive and non-erosive gastritis/duodenitis, and short segment Barret’s esophagus needed medical management. Small- or medium-sized sliding hiatal hernias were seen in 18.7% of patients with no effect on surgery. Moreover, 88.8% of patients with normal mucosal appearance were asymptomatic, but 92.6% in the group with abnormal EGD were symptomatic (p=0.01). Changes in surgical plan and time occurred in 63.6%, but after eliminating H. pylori eradication, it was 15.4%.
Considering gastric cancer and the high prevalence of H. pylori in Iran, using EGD and histopathological examination as an investigation in the preoperative assessment would have a significant impact on patients undergoing RYGB surgery.
