对单孔法与双孔法腹腔镜下小儿疝囊高位结扎术的疗效进行分析，评价其临床应用效果。

选取2017年6月至2018年8月，扬州大学附属医院收治的100例的腹股沟斜疝患儿，随机分为对照组（50例）和试验组（50例）。对照组患儿行双孔法腹腔镜下疝囊高位结扎术，试验组患儿采用单孔法腹腔镜疝下囊高位结扎术。比较2组患儿手术时间、对侧未闭鞘状突发生率、切口大小、术后24 h疼痛情况、并发症发生率和复发率发生情况。

试验组中切口（7.40±1.01）mm小于对照组（9.58±1.56）mm，试验组并发症发生虑3例（6%）低于对照组10例（20%），差异有统计学意义（P<0.05）；2组手术时间、对侧未闭鞘状突发生率、复发率比较，差异无统计学意义（P>0.05）。

两种术式治疗小儿腹股沟斜疝均安全有效，单孔法操作相对困难，但并发症发生率较低，值得推广。

To analysis the clinical effect of single-port method and double-port method of laparoscopic high ligation of pediatric hernia sac.

100 children with oblique inguinal hernia admitted to affiliated hospital of Yangzhou hospital from June 2017 to August 2018 were randomly divided into the control group (n=50) and the study group (n=50). Children in the control group were treated with double-port laparoscopic high ligation of hernia sac, while children in the study group were treated with single-port laparoscopic high ligation of hernia sac. Surgical duration, CPPV incidence, incision size, pain at 24 h after surgery, complication incidence, and recurrence rate were compared.

The incision size (7.40±1.01) mm in the study group was smaller than that in the control group (9.58±1.56) mm. The complications incidence such as pain, vascular injury and subcutaneous pneumoconiosis in the study group ([3(6%)] were lower than that in the control group [10(20%)] The difference was statistically significant (P<0.05). There were no statistically significant differences in surgical duration, CPPV incidence, or recurrence rate between the two groups (P>0.05).

Both methods are safe and effective in the treatment of children with oblique inguinal hernia. Single-port method is relatively difficult for beginners to operate. But the incidence of complications is low. It is worth popularizing.
