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.
