Comparison of the open tension-free mesh-plug, transabdominal preperitoneal (TAPP), and totally extraperitoneal (TEP) laparoscopic techniques for primary unilateral inguinal hernia repair: a prospective randomized controlled trial.
BACKGROUND
The open tension-free mesh-plug hernia technique, transabdominal preperitoneal (TAPP) technique, and totally extraperitoneal (TEP) laparoscopic technique all are common surgical procedures for primary unilateral inguinal hernia repair. However, the choice of the right surgical procedure still is controversial in China. This study aimed to compare open tension-free hernioplasty with two laparoscopic hernia repairs.


METHODS
In this study, 164 male patients with primary unilateral inguinal hernia were randomized to undergo an open operation with mesh-plug and patch, TAPP, or TEP.


RESULTS
Completion of the study required 3 years, from February 2006 to February 2009. Of the 164 patients, 62 underwent open repair, 50 had TAPP, and 52 had TEP. The patients then were followed up for 15.6 ± 8.5 months. The average operating time for the open repair group was significantly shorter than for the other two groups (p < 0.001). The cost for the open repair group also was significantly less than for the other two groups (p < 0.001). By contrast, the pain scores in the open mesh group were significantly higher than in the other two groups (p < 0.001). The hospital stay and the recovery time both were significantly longer in open repair group than in the other two groups (p < 0.001). No major complications or recurrence was found in any of the groups.


CONCLUSIONS
The findings show that open tension-free mesh-plug hernia repair, TAPP, and TEP are safe and effective for patients with primary unilateral inguinal hernia. Both TAPP and TEP are superior to open repair in terms of less postoperative pain and faster recovery time. The authors therefore recommend laparoscopic repair techniques as the preferable choice of surgical procedure. However, they think open repair will remain a practical solution in China because of its lower cost, short learning period, and need for no special equipment.
