Abstract
The purpose of this study was to compare a lightweight mesh to a standard polypropylene hernia mesh in endoscopic extraperitoneal hernioplasty in recurrent hernias. A total of 140 men with recurrent unilateral inguinal hernias were randomised to a totally extraperitoneal endoscopic hernioplasty (TEP) with Prolene or VyproII in a single-blinded multi-center trial. The randomisation and all data handling were performed through the Internet. 137 patients were operated as allocated. Follow-up was completed in 88% of the patients. The median operation times were 55 (24–125) min and 53.5 (21–123) min for the Prolene and VyproII groups, respectively. The meshes had comparable results in the surgeon’s assessment of the handling of the mesh, return to work, return to daily activities, complications, postoperative pain and quality of life during the first 8 weeks of rehabilitation, except in General Health (GH) SF-36, where the VyproII-group had a significantly better score (P=0.045). The use of Prolene and VyproII-meshes in endoscopic repair of recurrent inguinal hernia seems to result in similar short-term outcomes and quality of life.
