探讨单孔腹腔镜辅助双钩疝针在小儿腹股沟斜疝治疗的应用价值以及其可行性和安全性。

回顾性分析2016年3月至2017年3月，皖南医学院弋矶山医院应用单孔腹腔镜辅助经皮穿刺并于腹膜外行疝内环口结扎术的448例小儿腹股沟斜疝患儿的临床资料，根据术式不同分为2组，其中221例采用腹腔镜下双钩疝针内环口结扎术（双钩针组），227例腹股沟斜疝患儿采用腹腔镜下单钩疝针内环口结扎术（单钩针组）。2组腹股沟斜疝患儿手术均由同一手术者操作完成，对比2组患儿手术的临床效果以及术中、术后并发症。

双钩针组、单钩针组单侧手术平均耗时分别为（12.42±1.60）min、（18.32±2.00）min，差异有统计学意义（P<0.05）；双侧手术时间分别为（18.17±2.50）min、（24.39±4.67）min，差异有统计学意义（P<0.05）；术后住院时间分别为（2.55±0.69）d、（2.63±0.74）d，差异无统计学意义（P>0.05）。双钩针组回访至今无并发症，未见复发。单钩针组有1例患儿在术后6个月出现穿刺部位线结反应，另有1例患儿同侧腹股沟斜疝术后1年复发。

双钩疝针用于治疗儿童腹股沟斜疝不仅具有手术操作方法简单，能够注水分离腹膜组织，不会结扎腹壁组织或者遗留局部的腹膜间隙等优点，而且完全能够保证在腹膜外间隙行结扎内环口的完整性和安全性，可以在临床上推广。

To explore the application value of single-hole laparoscope-assisted double-hooked needle repair in the treatment of indirect inguinal hernia in children and its feasibility and safety.

From March 2016 to March 2017, a retrospective analysis was conducted on children who underwent hernia surgery in the YijiShan hospital. A total of 448 cases of pediatric inguinal hernia received single-hole laparoscopic-assisted percutaneous puncture and internal ring ligation of the peritoneum. According to the different methods, patients were divided into two groups: 221 cases were treated with double-hooked needle, and 227 cases were treated with single-hooked needle. The two groups of children with indirect inguinal hernia were operated by the same operator. The clinical effects, intraoperative and postoperative complications of the two groups were compared.

The average time of unilateral hernia surgery in double-hook group and single-hook group was (12.42±1.60) minutes, (18.32±2.00) minutes, respectively; the bilateral operation time were (18.17±2.50) minutes, (24.39±4.67) minutes, respectively. The postoperative hospital stay was (2.55±0.69) days and (2.63±0.74) days, respectively. No complications and no recurrence in the double-hook group in the follow-up time. In the single-hook group, there was 1 case of postoperative puncture site "knot reaction" at 6 months after operation, and 1 case of recurrence at 1 year.

Double-hook used in the treatment of indirect inguinal hernia of children is not only simple, can inject water to separate the peritoneal tissue, will not ligate the abdominal wall tissue or left the local peritoneum gap, and also can guarantee the completeness and safety of the internal ring ligation in the preperitoneal space.
