PURPOSE Transabdominal preperitoneal hernia mesh plasty (TAPP) offers significant benefits to patients undergoing bilateral inguinal hernia repair. We evaluated a novel pre-shaped, large-pored, titanium-coated, lightweight polypropylene mesh for bilateral placement as an alternative to two separate meshes. METHODS Thirty-six patients underwent elective surgical repair of bilateral inguinal hernias with the new mesh at three departments of surgery in Linz and Graz, Austria, between May 1, 2015 and June 30, 2017. RESULTS All operations were completed without intraoperative complications or conversion to open procedures. The mean operation time was 74 min. There were no postoperative procedure-related complications with the exception of one hematoseroma of the spermatic cord. Two symptomatic medial recurrences (2/36 patients = 5.6%, 2/72 hernia repairs = 2.8%, respectively) after supravesical and medial hernia repair with the bilateral mesh were seen at structured follow-up examinations 6 and 12 months postoperatively. CONCLUSION Treatment of bilateral inguinal hernias with the newly designed bilateral mesh for TAPP theoretically brings benefits in terms of resistance to forces acting on the mesh. The larger area may decrease the risk for mesh bulging and recurrence, and one large mesh might provide more stable support than two separate meshes overlapping at the midline. The results of our study do not confirm these theoretical benefits regarding a high recurrence rate (2.8%) after treatment of medial hernia defects. We recommend re-designing the mesh with only a small central slit, which would provide a broader mesh bridge with sufficient overlap for all types of inguinal and femoral hernias, including medial and supravesical defects. After the mesh has been re-designed, a new study should evaluate its real benefits before it is marketed.
