Abstract: Objective To explore the feasibility, effectiveness and safety of laparoscopic high ligation of hernial sac with a self-made suture needle (remade from epidural catheter needle) by comparing with minithoracotomy high ligation of hernial sac for children's hernia. Methods The clinical data of 56 children with inguinal hernia in our hospital between April, 2014 and April, 2016 were analyzed retrospectively.The patients were divided into two groups according to the operation methods.Twenty-eight cases of the laparoscopy group were treated with laparoscopic high ligation of hernial sac with a self-made epidural catheter needle, while other 28 cases of the open surgery group were treated with minithoracotomy high ligation of hernial sac.The intraoperative and postoperative conditions of patients in the two groups were recorded.The operation time, surgical incision, postoperative complication, postoperative recurrence rate and hospitalization time between the two groups were compared.The data was analyzed by SPSS 19.0 statistical software, setting P < 0.05 for statistically significant. Results Compared with minithoracotomy high ligation method, laparoscopic high ligation of hernial sac was with advantage in the operation time (t=5.441, 5.403, all P < 0.001) and postoperative complications (χ²=4.082, P=0.043), the difference was statistically significant (P < 0.05).The difference in recurrence rate and hospitalization time was not significant. Conclusion The laparoscopic high ligation of hernial sac with a self-made suture needle is a simple, effective and minimally invasive procedure with a shorter operative time, smaller incision, less postoperative complications, clearer intraoperative vision.The contralateral occult hernia can be found.At the same time, the abdominal cavity detection can be performed, which can provide with a new method for children's inguinal hernia treatment and get the approbation of the parents.Therefore it was worthy of clinical promotion.
