To explore the safety, feasibility, and clinical efficacy and summarize the surgical experience of wrapping the residual stomach with the greater omentum in laparoscopic sleeve gastrectomy (LSG).

To retrospectively analyze the clinical data and follow-up results of 5 obese patients admitted to the department of hepatobiliary and pancreatic surgery of People’s Hospital of Bayinguoleng Mongol Autonomous Prefecture from May 2022 to February 2024 with 42 cases of obesity undergoing LSG by wrapping the stomach with the greater omentum, including two male and three female patients, aged 28-52 years old, with a BMI of 34.5-42.7 kg/m².

The five patients completed the surgery without intraoperative blood transfusion or transit. Open abdomen, operation time was 90-130 min, intraoperative bleeding was 20-50 ml, and postoperative hospitalization time was 4-6 days. After 12 months of follow-up, there were no complications such as postoperative bleeding, gastric leakage, gastroesophageal reflux disease (GERD), stenosis, and obstruction, and the patients were satisfied with the weight reduction efficacy of the surgery and postoperative rehabilitation.

It is safe, feasible, and clinically effective to wrap the residual stomach with the greater omentum during LSG, and the wrapping of the stomach with the greater omentum autologous tissue can effectively prevent the dilatation of the residual stomach and the occurrence of intra-thoracic sleeve migration, thus avoiding postoperative weight regain and the occurrence of GERD.
