Abstract

Background

Compared with open herniorrhaphy, laparoscopic herniorrhaphy can yield more favorable clinical outcomes. However, previous studies failed to give definite answer for comparison between laparoscopic inguinal hernia repair approaches. This study aimed to systematically determine the differences in recurrence rate, duration of return to work, pain, surgery duration, and duration of hospital stay between transabdominal preperitoneal (TAPP) and totally extraperitoneal (TEP) approach for inguinal hernia.

Methods

PubMed, Embase, and Cochrane Library (including the Cochrane Central Register of Controlled Trials) abstracts up to September 2017 were searched for randomized controlled trials (RCTs) comparing TAPP or TEP hernia repairing. The hernia recurrence rate, time to return to work, analgesic consumption, surgery duration, hospital stay, and the pain score were recorded with subgroup analysis of the hernia type.

Results

Sixteen RCTs that randomized 1519 patients with hernia into TEP and TAPP repair groups were analyzed in this study. The results revealed that TEP repair resulted in shorter hospital stay of primary cases (MD − 0.87, 95% CI − 1.67 to − 0.07) but was associated with a longer operative duration in recurrent hernia group (MD 3.35, 95% CI 0.16 − 6.54).

Conclusions

TEP and TAPP have their own advantages. TEP repair reduces short-term postoperative pain more effectively than TAPP repair and results in shorter hospital stay of primary cases. In contrast, TAPP repair is correlated with shorter surgery duration. These findings show that shared decision-making regarding both approaches of laparoscopic hernia repair may be needed.
