Perioperative antibiotic prophylaxis in robotic-assisted ventral hernia repair: a propensity score-matched analysis.

Of the 260 patients included in the study, 258 met the inclusion criteria, of whom 174 (67.4%) received antibiotic prophylaxis and 84 (32.6%) did not.

Propensity score matching yielded 78 well-balanced pairs (all post-match SMDs ≤ 0.13, propensity score SMD 0.007).

The median length of stay (LOS) was two days in both groups (Wilcoxon p = 0.507).

In the subgroup analyses, no stratum could be identified in which prophylaxis significantly reduced SSOs.
