目的 评价侧方入路单孔腹腔镜全内脏囊分离技术（L-SILTVS）在脐疝修补中的应用效果。方法 回顾性分析2023年6月至 2025年12月宁波大学附属第一医院肝胆胰疝外科、宁波市北仑区中医院普外科收治的采用L-SILTVS完成脐疝修补术的28例脐疝病人的临床资料。观察并记录术中腹膜质量、手术时间、术后疼痛及其他并发症发生情况。结果 28 例病人中27例顺利完成手术，1例术中更改入路完成，无中转开放手术。病人年龄为（54.3±15.9）岁，BMI为29.4±4.4。手术时间为64（54，93）min，出血量为（3.6±2.7）mL。观察腹膜存在完整（17例）、菲薄（10例）、脆弱（1例）3种不同类型；术中腹膜破损20例（71.4%），未破损8例（28.6%）。术后6、24、48 h视觉模拟评分分别为 （3.0±0.6）分、（2.0±0.6）分、（1.0±0.4）分，术后住院时间为（2.9±0.6）d。术后随访7（1~30）个月，无手术相关并发症发生。结论 对于符合适应证的脐疝病人，应用L-SILTVS实施手术的近期效果良好，但对技术要求高，需重视手术细节、评估腹膜质量并谨慎开展。

Objective To evaluate the clinical effectiveness of the lateral single-incision laparoscopic totally visceral sac separation technique (L-SILTVS) in the repair of umbilical hernia. Methods A retrospective analysis was conducted on 28 patients with umbilical hernia who underwent L-SILTVS between June 2023 and December 2025 at the First Affiliated Hospital of Ningbo University, Ningbo Beilun Traditional Chinese Medicine Hospital. Intraoperative peritoneal quality, operation time and postoperative pain, complications were observed and recorded. Results Among the 28 patients, the procedure was successfully completed in 27 cases, with 1 case requiring a modification in the operative approach; no conversion to open surgery occurred. The mean age was (54.3±15.9) years, and the mean body mass index was 29.4±4.4. The median operative time was 64 (54, 93) minutes, and the median blood loss was (3.6±2.7) mL. Three distinct peritoneal types were identified: intact(17 cases), attenuated(10 cases), and friable(1 cases). Intraoperative peritoneal rupture occurred in 20 cases（71.4%）, and no rupture in 8 cases（28.6%）.Postoperative visual analog scale pain scores at 6, 24, and 48 hours were (3.0±0.6), (2.0±0.6), and (1.0±0.4)points, respectively. The mean postoperative hospital stay was (2.9±0.6) days. Patients were followed up for 7 (1-30) months postoperatively, and no surgery-related complications were observed. Conclusion L-SILTVS demonstrates favorable short-term outcomes in specific umbilical hernia patients with appropriate indications. However, the procedure is technically demanding, highlighting the importance of meticulous surgical details, peritoneal status evaluation, and cautious implementation.
