探讨腹腔镜袖状胃切除术（LSG）大网膜包裹残留胃的安全性、可行性、临床疗效，并总结手术经验。

回顾性收集2022年5月至2024年2月新疆巴音郭楞蒙古自治州人民医院肝胆胰外科收治的42例肥胖症患者中行LSG大网膜包裹胃的5例患者，其中男性2例，女性3例，年龄28~52岁，体质量指数范围为34.5~42.7 kg/m²，收集并分析其临床资料（如手术时间、术中出血量、住院时间等）及随访结果（如并发症）。

5例患者均顺利完成手术，无术中输血或中转开腹，手术时间为90~130 min，术中出血量为20~50 ml，术后住院时间为4~6 d。随访满12个月，无术后出血、胃漏、胃食管反流病（GERD）、胃腔狭窄与梗阻等并发症，患者均对手术减重效果及术后康复满意。

LSG大网膜包裹残留胃是安全、可行的，且临床疗效确切，大网膜自体组织包裹胃可有效防止残留胃的扩张并预防袖状胃胸腔内上移的发生，以避免术后复胖及GERD的发生。

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.
