Sutureless Lichtenstein: First results of a prospective randomised clinical trial

Inguinal hernia repair, according to Lichtenstein, is very popular due to its minimal invasiveness (local anaesthesia), easy and reproducible technique, low recurrence rate, and low morbidity. However, recent publications demonstrate an elevated rate of chronic irritations and pain, probably due to tension or nerve compression by the fixing sutures. We, therefore, established a concept to avoid these sutures by attaching the prosthesis with glue. After a pilot study, a randomised prospective trial was started. The aim of our study was to compare the results of the classical Lichtenstein repair (group 1) vs the "Sutureless Lichtenstein" (group 2) in terms of postoperative complications and recurrences. Operative access and management of the hernial sac was equal to Lichtenstein for both groups. In group 1, we sutured the mesh with PDS 2/0; in group 2, the mesh was glued with n-butyl-cyanoacrylate. In both groups, the operation was then completed according to Lichtenstein, and unrestricted activity was allowed after 2 weeks. A total of 46 patients have been operated on. The follow-up results at 3 weeks and {3 months}were: group 1 (n=24) vs group 2 (n=22): recurrences 0 {0} vs 0 {0}, minor pain 8 {4} vs 4 {1}, local numbness 14 {10} vs 10 {6}. No adhesive-related complications were seen. Patients will be followed for 2 years. The results in group 2 were excellent, and there was no difference vs group 1. Furthermore, there was a tendency for better results in group 2. These results are very promising and justify a continuation of the study.
