Short-term comparison between preperitoneal and intraperitoneal onlay mesh placement in robotic ventral hernia repair.

Abstract

PURPOSE:

The aim of this study was to compare perioperative results of robotic IPOM (r-IPOM) and robotic TAPP (r-TAPP) in ventral hernia repair, and to identify risk factors associated with postoperative complications.

METHODS:

After obtaining balanced groups with propensity score matching, the comparative analysis was performed in terms of perioperative and early outcomes. All variables were also examined in a subset analysis in patients with and without complications. Multivariable regression analysis was used to identify independent risk factors associated with the development of complications.

RESULTS:

Of 305 r-IPOM and r-TAPP procedures, 104 patients were assigned to each group after propensity score matching. There was no difference in operative times between two groups. Although postoperative complications were largely minor (Clavien-Dindo grade-I and II), the rate of complications was higher in the r-IPOM group within the first 3-weeks (33.3% in r-IPOM vs. 20% in r-TAPP, p = 0.039). At the 3-month visit, outcomes between groups were not different (p = 0.413). Emergency department re-visits within 30-days and surgical site events were also higher in the IPOM group (p = 0.028, p = 0.042, respectively). In regression analysis, the development of complications was associated with incisional hernias (p = 0.040), intraperitoneal mesh position (p = 0.046) and longer procedure duration (p = 0.049).

CONCLUSION:

Our data suggest r-IPOM may be associated with increased complication rates in the immediate postoperative period when compared to r-TAPP. However, at 3 months, outcomes are comparable. More investigation is needed in this area, specifically with regards to long-term follow-up and multicenter data, to determine the true value of extra-peritoneal mesh placement.
