Abstract

Abstract:

Objective To investigate the effect of laparoscopic sleeve gastrectomy (LSG) on gastroesophageal reflux disease (GERD) after surgery in obese patients with type Ⅰ hiatal hernia (HH). Methods A retrospective analysis was conducted on 63 obese patients admitted between March 2023 and December 2024. The patients were divided into two groups: group A, simple obesity (n=50), and group B, obesity with type ⅠHH (n=13). Both groups underwent SG, and no concurrent HH repair was performed in Group B. Gerd-Q scores were used to evaluate reflux symptoms preoperatively and at 3 and 6 months postoperatively, and the differences between the groups were compared. Results There was no significant difference in the Gerd-Q scores between the two groups before surgery and 3, 6 months after surgery (all P>0.05). When comparing the Gerd-Q scores of the two groups of patients at 3, 6 months after surgery with those before surgery, there were no significant differences (P>0.05). There was no significant difference in the prevalence of GERD between the two groups before surgery and 3, 6 months after surgery (all P>0.05). Conclusions For obese patients with type ⅠHH, undergoing LSG did not increase the incidence of postoperative GERD.

Key words: Laparoscopic sleeve gastrectomy(LSG), Hiatal hernia(HH), Gastroesophageal reflux disease(GERD), Gerd-Q
