Randomized Clinical Trial Comparing Laparoscopic Totally Extraperitoneal Approach with Open Mesh Repair in Inguinal Hernia

Abstract
The aim of this study was to compare laparoscopic totally extraperitoneal approach (TEP) repair with tension-free open mesh repair in inguinal hernia. One hundred thirty-four patients were allocated randomly to undergo TEP repair (n = 67) or open mesh repair (n = 67). Operative and postoperative outcomes were determined. The mean of operating time (49.67 ± 14.11 vs. 56.64 ± 12.32; P = 0.001), visual analog scale score (2.73 ± 1.69 vs. 4.61 ± 1.77; P = 0.001), hospital stay (1.8 ± 0.7 vs. 2.7 ± 1.6; P = 0.001), and duration of recovery (10.8 ± 7.4 vs. 15.2 ± 8.5; P = 0.001) was significantly less for TEP repair when compared with open mesh repair. The incidence of complications (13.4% vs. 16.4%; P = 0.631) and recurrence (2.9% vs. 5.9%; P = 0.407) was approximately equal in each group. Our results showed that laparoscopic TEP repair is superior to open mesh repair.
