Exploring the effect of preserving the integrity of the gastric antrum and His angle during laparoscopic gastric sleeve resection on postoperative gastroesophageal reflux disease.

Retrospective analysis of 76 obese patients who underwent laparoscopic gastric sleeve resection surgery at Beijing Luhe Hospital affiliated with Capital Medical University from Jan. 2022 to Aug. 2023, and patients who completed 6 months of postoperative follow-up. Divided into Group A with 40 cases (preserving the integrity of gastric antrum and His angle surrounding tissues) and Group B with 36 cases (not preserving the integrity of gastric antrum structure and His angle surrounding tissues). Compare and analyze the differences in body mass index (BMI), percentage excess weight loss (EWL) and GERD-Q (Gastroesophageal Reflux Disease Questionnaire) scores between two groups of patients at 1, 3, and 6 months after surgery.

There was no significant difference in BMI between the two groups of patients before and 6 months after surgery (39.44 ± 6.032 kg/m² vs. 41.74±6.677 kg/m^2; 28.99±4.763 kg/m² vs. 29.82±4.651 kg/m^2, P>0.05). A. The incidence rate of GERD disease before operation was 27.5% (11 cases) and 27.8% (10 cases) respectively in group B, with no significant difference (P>0.05). The incidence rate of GERD disease (Gerd-Q score ≥ 8) in group A was 30.0% (12 cases), 27.5% (11 cases), 22.5% (9 cases) respectively at 1, 3, and 6 months after surgery, which was significantly lower than 41.7%(15 cases), 38.9% (14 cases), and 36.1% (13 cases) in group B, P<0.05.

Preserving the integrity of gastric antrum and His angle does not affect the weight loss effect, and is conducive to reducing the incidence rate of GERD after gastric sleeve resection.
