title: A continuous debate on contralateral processus vaginalis: evaluation technique and approach to patency.
abstract: We present our experience with the transinguinal diagnostic laparoscopy and discuss its efficacy in evaluating the contralateral side in unilateral inguinal hernias. The possible influence of the initial side of hernia, age and gender on recognized bilateralism were also evaluated in two study groups (diagnostic laparoscopy vs clinical diagnosis). In this retrospective study, we evaluated 36 bilateral, 158 left-sided and 303 right-sided consecutive inguinal hernia cases. A total of 211 out of 461 unilateral cases underwent hernia repair and transinguinal laparoscopic evaluation of the contralateral side. Complications and difficulties of the technique, the mean duration of laparoscopy and operative times were additionally analyzed from operation charts. In this study, bilateralism was determined by transinguinal laparoscopy in Group 1 (children with a contralateral patent processus vaginalis) and clinically in Group 2 those who had a metachronous hernia. The patients were also analyzed according to the side of the inguinal hernia, age and gender in both groups. We found an overall positive contralateral patency in 41 cases (19.4%). We failed to perform a successful diagnostic laparoscopy in six cases (2.7%). No anesthetic or surgical complications were noted. Transinguinal laparoscopy did not add any considerable time to the mean operation time. The incidence of bilateralism in Group 1 was higher in girls than boys. Clinically detected bilateralism was significantly higher in 0-6 month age group and contralateral patency detected via laparoscopy was high in all other age groups. We may conclude that transinguinal diagnostic laparoscopy is a feasible technique in children. We advocate its use as a tool with minimal complication risk even in the hands of novice.
