Operation and RecoveryNominal variables are reported as counts and percentages (in parentheses); continuous variables are reported as means and standard deviations.At the 30-day follow-up, SSI occurred in one patient in the SM group (2%) and two patients in the BM group (4%) (difference − 2, 95% confidence interval − 12 to 8, p > 0.90). In the SM group, one patient had Clavien-Dindo 4 anastomotic leakage with re-operation and mesh removal. In the BM group, one complication was a Clavien-Dindo 2 superficial wound infection treated with oral antibiotics. The other was a Clavien-Dindo 3b abscess requiring re-operation and mesh removal. A total of 38 patients (86%) in the SM group and 43 patients (90%) in the BM group had a completely healed surgical wound by the 30-day follow-up (Table
