Which is the best laparoscopic approach for inguinal hernia repair: TEP or TAPP? A systematic review of the literature with a network meta-analysis

Abstract

Background

Totally extraperitoneal (TEP) repair and transabdominal preperitoneal (TAPP) repair are the most used laparoscopic techniques for inguinal hernia treatment. However, many studies have shown that laparoscopic hernia repair compared with open hernia repair (OHR) may offer less pain and shorter convalescence. Few studies compared the clinical efficacy between TEP and TAPP technique. The purpose of this study is to provide a comparison between TEP and TAPP for inguinal hernia repair to show the best approach.

Methods

We performed an indirect comparison between TEP and TAPP techniques by considering only randomized, controlled trials comparing TEP with OHR and TAPP with OHR in a network meta-analysis. We considered the following outcomes: operative time, postoperative complications, hospital stay, postoperative pain, time to return to work, and recurrences.

Results

The two techniques improved some short outcomes (such as time to return to work) with respect to OHR. In the network meta-analysis, TEP and TAPP were equivalent for operative time, postoperative complications, postoperative pain, time to return to work, and recurrences, whereas TAPP was associated with a slightly longer hospital stay compared with TEP.

Conclusions

TEP and TAPP improved clinical outcomes compared with OHR, but the network meta-analysis showed that TEP and TAPP efficacy is equivalent. TAPP was associated with a slightly longer hospital stay compared with TEP.
