Abstract

Purpose

Laparoscopic percutaneous extraperitoneal closure (LPEC) is known to reduce the incidence of metachronous contralateral hernia (MCH) compared to conventional hernia repair. We herein describe the effects of insistent screening for an irregular orifice of the contralateral patent processus vaginalis (CPPV).

Methods

All patients who underwent LPEC between 2003 and 2013 were reviewed. We started insistent screening for a CPPV in July 2010. The surgically treated cases before June 2010 were assigned to the former group, while those treated after July 2010 were in the latter group. The data were retrospectively collected from medical records. The statistical analysis was performed using the Mann–Whitney U test or Chi square test. A value of P < 0.05 was considered to be significant.

Result

A total of 1113 patients (514 males and 599 females) ranging in age from 3 months old to 15 years old (median 4.6 years old), were reviewed. Of the 626 patients in the former group, a CPPV was detected in 227 patients. Of the 487 patients in the latter group, a CPPV was detected in 271 patients. The incidence of a CPPV significantly increased over time (P < 0.001). We encountered five cases of MCH, all of which belonged to the former group (P = 0.048).

Conclusions

The increased detection of a CPPV by insistent screening seemed to cause a decrease in the incidence of MCH.
