Abstract:【Objective】 To retrospectively analyze the various factors affecting laparoscopic percutaneous extraperitoneal closure (LPEC) for pediatric inguinal hernia (PIH), and to explore the measures. 【Methods】 A retrospective analysis was carried out for 218 cases which were treated with transumbilical laparoscopic LPEC using 3 different techniques between March 2011 and March 2013. The adverse factors of the LPEC procedures, the measures and postoperative complications were collected. 【Results】 212 LPEC were completed and the other 6 were converted to conventional surgery. There were no recurrences. Some adverse factors were encountered during the procedures and solved properly including unclear visualization of vas deferens (82), peritoneum gauffer (69), old age or huge hernias (32), full bladders (5), full colons (2), tear of peritoneum (2), Extraperitoneal emphysema (4), epiploon conglutinated to the sac (2). 【Conclusion】 The majority of children with PIH can be cured by LPEC, but some various adverse factors would be encountered which must be solved with some techniques and principles.
