TAPP versus lichtenstein techniques for bilateral inguinal hernia repair: A systematic review and meta-analysis.

Inguinal hernia repair is one of the most common surgical procedures performed worldwide. However, very few studies report data on the laparoscopic advantages of bilateral inguinal hernia (BIH) repair over the open approach. Therefore, this meta-analysis was conducted to compare the effectiveness of the laparoscopic trans-abdominal pre-peritoneal (TAPP) technique with the open Lichtenstein repair technique (OLR) for the repair of BIH.
