探讨复合补片与生物补片在腹腔镜腹腔内补片修补术（IPOM）治疗脐疝中的疗效并进行对比研究。

本研究为回顾性队列研究，连续纳入2018年7月至2024年9月济南市中心医院胃肠外科收治的接受腹腔镜IPOM治疗的93例脐疝患者。根据术中使用补片类型分为复合补片组（n=43）与生物补片组（n=50）。所有患者均采用腹腔镜腹腔内补片修补术（IPOM）。收集了手术时间、术后排气时间、术后住院天数、感染、复发、慢性疼痛等指标，使用SPSS 25.0软件进行数据分析。

2组患者的性别、年龄、体重指数、疝环直径比较，差异均无统计学意义（P>0.05）。2组患者的手术时间、术后住院时间，以及感染、慢性疼痛比较，差异均无统计学意义（P>0.05）。生物补片组术后排气时间早于复合补片组[（1.50±0.29）d比（2.30±0.67）d，P<0.001]。生物补片组复发2例（4.0%），复合补片组无复发，2组复发率比较差异无统计学意义（P=0.497）。

两种补片的手术效果相近，生物补片组在术后排气时间方面有一定优势，但其复发率需要引起关注。

To investigate and compare the efficacy of composite mesh and biological mesh in laparoscopic intraperitoneal onlay mesh (IPOM) repair for umbilical hernia.

This single-center retrospective cohort study consecutively enrolled 93 patients with umbilical hernia who underwent laparoscopic IPOM repair in the Department of Gastrointestinal Surgery, Jinan Central Hospital, from July 2018 to September 2024. Based on the type of mesh used intraoperatively, patients were divided into the composite mesh group (n=43) and the biological mesh group (n=50). All patients underwent laparoscopic IPOM repair. Data collected included operative time, postoperative time to first flatus, postoperative hospital stay, incidence of infection, recurrence, and chronic pain. Statistical analyses were performed using SPSS version 25.0.

There were no statistically significant differences between the two groups in terms of sex, age, body mass index, and hernia ring diameter (P>0.05). Similarly, no significant differences were observed between the two groups with respect to operative time, postoperative hospital stay, incidence of infection, or incidence of chronic pain (P>0.05). Notably, the postoperative time to first flatus was significantly shorter in the biological mesh group compared with the composite mesh group [(1.50±0.29) days vs. (2.30±0.67) days, P<0.001]. Recurrence occurred in two cases(4.0%) in the biological mesh group and in none in the composite mesh group; however, the difference in recurrence rate between the two groups was not statistically significant (P=0.497).

Both types of mesh demonstrated comparable surgical outcomes. The biological mesh group showed an advantage in terms of postoperative time to first flatus, although its recurrence rate warrants further attention.
