Analysis of Risk Factors for Children With Heterochronous Indirect Hernia

Summary

Laparoscopic contralateral patent processus vaginalis (CPPV) repair in infancy and childhood is still debatable, due to the high CPPV rate but low contralateral metachronous hernia (MCIH) rate. In order to found risk factors for MH, we conducted this prospective study.

This is an multi-center investigator-initiated observational prospective trial. After informed all the benefits and risks of repair CPPV simultaneously, those patients with unilateral inguinal hernia whose parents preferred not to repair CPPV simultaneously will be assigned in the study. All information about demographic data, hernia side, CPPV type and CPPV diameter will be recorded. The subjects will be followed up until MCIH developing or to 24 months postoperatively. Patients will be analyzed to identify the risk factors for MH.
