Can ventral TAPP achieve favorable outcomes in minimally invasive ventral hernia repair? A systematic review and meta-analysis.

ABSTRACT

PURPOSE: The concept of the transabdominal preperitoneal (TAPP) was transferred from the inguinal hernia repair to be adopted in minimally invasive ventral hernia repair (VHR) and since then it has been gaining popularity. However, there are minimal data supporting the ventral TAPP (vTAPP) technique which may lead to reticence in the adoption of this approach. The aim of this meta-analysis was to evaluate the outcomes of patients who received minimally invasive vTAPP for VHR. STUDY DESIGN: A systematic search was performed of PubMed, Science Direct, Google Scholar and Cochrane Library until July 2022. We selected studies that compared the vTAPP technique with any of other minimally invasive techniques. A meta-analysis was done for the outcomes of perioperative characteristics and postoperative parameters. RESULTS: A total of 9 studies (1429 patients) were identified. vTAPP was associated with considerable benefit when compared to IPOM. vTAPP was less painful (MD = - 1.01; 95% CI [- 1.39, - 0.64], p < 0.00001), of reduced average cost (MD = - 457.10; 95% CI [- 457.27, - 456.92], p < 0.00001) and decreased SSI (OR = 0.29; 95% [0.09, 0.96], p = 0.04). On the other hand, the vTAPP approach consumed less operative time (MD - 31.01, 95% CI [- 33.50, - 28.51]), p < 0.00001) and shorter hospital stay than the e-TEP approach. CONCLUSION: vTAPP appears to be safe and effective procedure for VHR, superior or similar to other minimally invasive techniques for perioperative characteristics and short-term outcomes.
