Objective: To investigate the risk factors for recurrence of oblique inguinal hernias in children after laparoscopic high ligation of the hernia sac. Methods: The clinical data of 306 children with oblique inguinal hernias undergoing laparoscopic high ligation of the hernia sac from January 2013 to January 2016 were collected. The risk factors affecting the postoperative recurrence of the pediatric patients were analyzed. Results: In these 306 patients (401 sides), recurrence occurred in 13 cases, and the recurrence rate was 3.24%. Univariate analysis showed that age, diameter of the deep inguinal ring and ligation thread were significantly associated with recurrence after laparoscopic high ligation of the hernia sac (χ2=6.275, 9.145, and 11.371, P=0.043, 0.010, and 0.001); multivariate Logistic regression analysis revealed that older age, large diameter of the deep inguinal ring and use of absorbable sutures were independent risk factors for recurrence after laparoscopic high ligation of the hernia sac (OR=3.466, 95% CI=1.432–8.389; OR=1.988, 95% CI=1.237–3.194; OR=1.089, 95% CI= 1.015–1.168, all P<0.05). Conclusion: Older age, large diameter of the deep inguinal ring and use of absorbable sutures are the main risk factors for recurrence of oblique inguinal hernias in children after laparoscopic high ligation of the hernia sac. In children with risk factors, the modified laparoscopic procedure should be considered, postoperative monitoring should be enhanced, and use of absorbable suture should be avoided to reduce the recurrence rate.
