Laparoscopic Transabdominal Preperitoneal Inguinal Hernia Repair Using Memory-Ring Mesh: A Pilot Study

Purpose. To evaluate the feasibility, safety, and effectiveness of laparoscopic transabdominal preperitoneal (TAPP) inguinal hernia repair using a memory-ring patch (Polysoft™ mesh). Patients and Methods. Between April 2010 and March 2013, a total of 76 inguinal hernias underwent TAPP repair using Polysoft mesh in 67 adults under general anesthesia. Three different senior resident surgeons performed TAPP repair under the instruction of a specialist surgeon. Nine patients had bilateral hernias. The 76 hernias included 37 indirect inguinal hernias, 29 direct hernias, 1 femoral hernia, 1 pantaloon hernia (combined direct/indirect inguinal hernia), and 8 recurrent hernias after open anterior hernia repair. The immediate postoperative outcomes as well as the short-term outcomes (mainly recurrence and incidence of chronic pain) were studied. Results. There was no conversion from TAPP repair to anterior open repair. The mean operation time was 109 minutes (range, 40-132) for unilateral hernia repair. Scrotal seroma was diagnosed at the operation site in 5 patients. No patient had operation-related orchitis, testicle edema, trocar site infection, or chronic pain during follow-up. Conclusions. The use of Polysoft mesh for TAPP inguinal hernia repair does not seem to adversely affect the quality of repair. The use of this mesh is therefore feasible and safe and may reduce postoperative pain.
