IntroductionIn the update of the guidelines of the European Hernia Society, open Lichtenstein and endoscopic techniques continue to be recommended as the surgical technique of choice for repair of unilateral primary inguinal hernias in men despite the fact that a meta-analysis had identified a higher recurrence rate for TEP compared with Lichtenstein operation. The Guidelines Group had taken that decision because one surgeon in one of the randomized controlled trials included in the meta-analysis had had a very high recurrence rate. Therefore, this study based on registry data now compares the outcome of TEP versus Lichtenstein repair.Patients And MethodsThe analysis of the Herniamed Registry compares the prospective data collected for male patients undergoing primary unilateral inguinal hernia repair using either TEP or open Lichtenstein repair. Inclusion criteria were minimum age of 16 years, male patient, primary unilateral inguinal hernia, elective operation, and availability of data on 1-year follow-up. In total, 17,388 patients were enrolled between September 1, 2009, and August 31, 2013. Of these patients, 10,555 (60.70 %) had a Lichtenstein repair and 6833 (39.30 %) a TEP repair.ResultsOn multivariable analysis, the surgical technique was not found to have had any significant effect on the recurrence rate (p = 0.146) or on the chronic pain rate (p = 0.560). Nor did the complication-related reoperation rates differ significantly between the two techniques (p = 0.084). But TEP was found to have benefits as regards the postoperative complication rate (p < 0.001), pain at rest rate (p = 0.011), and pain on exertion rate (p < 0.001). In the present registry study, no significant difference was identified in the recurrence rates between the TEP and Lichtenstein technique. TEP was found to have benefits compared with Lichtenstein repair as regards the postoperative complication rates, pain at rest, and pain on exertion.
