Effect of laparoscopic sleeve gastrectomy vs laparoscopic sleeve gastrectomy with reconstruction of His angle on weight loss and de novo GERD in people with obesity: a propensity score matching analysis

Purpose To evaluate the impact of laparoscopic sleeve gastrectomy with reconstruction of His angle (LSGRH) on gastroesophageal reflux disease (GERD) after laparoscopic sleeve gastrectomy (LSG). Materials and Methods Clinical data of patients with obesity who underwent LSG or LSGRH from January 2022 and January 2024 and completed follow-up in time were retrospectively analyzed by propensity score matching (PSM) analysis. Patients were assigned to either LSG group or LSGRH group according to the surgical method. Perioperative indicators, improvement of obesity and severity of GERD were compared in these two groups. Results There were 51 comparable pairs of patients from LSG and LSGRH group enrolled in this study after PSM. There was no significant difference in operative time, volume of intraoperative blood loss, hospital stay after operation, weight loss and severity of GERD 6 months after surgery. Conclusion Under the premise of no increase in operative time, volume of intraoperative blood loss and hospital stay after operation, LSG with reconstruction of His angle cannot prevent the occurrence of de novo GERD compared with LSG.
