Abstract

Objective: The aim of this study was to determine inguinal hernia recurrence rates 5 years after endoscopic totally extraperitoneal (TEP) inguinal hernia repair when either lightweight or heavyweight mesh was used. Background: Recurrence is an important complication of inguinal hernia surgery. Higher recurrence rates of Ultrapro lightweight meshes after TEP repair have been demonstrated, yet data regarding long-term follow-up are limited. Methods: From 2010 to 2012, 950 male adult patients with primary unilateral hernias were randomized to TEP hernia repair with heavyweight (Prolene) or lightweight (Ultrapro) mesh. Five years postoperatively, the validated PINQ-PHONE telephone questionnaire was carried out. Participants with a positive questionnaire reply were scheduled for a clinical visit. A recurrence was defined as a clinically detectable bulge in the operated groin on physical examination. Results: Data on development of recurrence could be obtained from 790 patients (83.2% 5-year follow-up rate). Four patients presented with a recurrence at the outpatient clinic between 2 and 5 years postoperatively. Thirty-five patients (4.6%) with a positive PINQ-PHONE reply (60.0% lightweight vs 40.0% heavyweight) were physically examined at the outpatient clinic. In 2 patients (lightweight) a recurrence was detected. The total 5-year recurrence rate after TEP hernia repair was 2.4% (3.8% lightweight, 1.1% heavyweight, P = 0.01). A significantly higher recurrence rate for lightweight mesh in primary direct hernias was found (P = 0.003). Conclusions: The overall recurrence rate 5 years after TEP repair was low. Ultrapro lightweight meshes showed higher recurrence rates than heavyweight meshes and are not recommended for endoscopic TEP inguinal hernia repair.
