Simultaneous repair of bilateral inguinal hernias: a prospective, randomized study of single versus double mesh laparoscopic totally extraperitoneal repair.

The aim of this study was to compare the double and the single mesh techniques, both used in the laparoscopic totally extra peritoneal (TEP) repair of bilateral inguinal hernia. Sixty-five patients with bilateral inguinal hernia were enrolled in a prospective, randomized trial comparing the single and the double mesh techniques. The single and the double mesh techniques compared favorably in terms of operating time, long-term morbidity, hospital stay, time for return to work, postoperative quality of life and recurrence rate. However, the cost of a single, large prosthesis was 38% to 40% lower than that of 2 small ones. The laparoscopic TEP repair of bilateral inguinal hernia with a large, single prosthetic mesh is a technically simple and safe procedure, which offers clear cost savings and a potentially shorter operating time over the double mesh repair. It is strongly recommended for the routine, laparoscopic TEP repair of bilateral inguinal hernias.
