Liver cancer frequently requires repeated liver resections due to the high recurrence rate. The aim of this study was to clarify whether subcuticular sutures reduce wound complication rates following repeat incisions. Data from 382 repeated liver resections in 1,245 consecutive patients were assessed. Patients were divided into a Subcuticular sutures group and a Skin staples group on the basis of the wound-closure method. To avoid bias in analysing wound complications, data were matched to adjust for patient background and operation variables. After matching, 82 matched, paired patients with subcuticular sutures or skin staples were compared. Total wound complication rate was significantly lower with subcuticular sutures than with skin staples (8.5% vs. 20.7%, p = 0.027). Incisional surgical site infection was also lower with subcuticular sutures than with skin staples (6.1% vs. 17.1, p = 0.028). Univariate analysis revealed 4 factors associated with wound complications: body mass index; serum albumin concentration; wound length; and closure with skin staples. Multivariate analysis revealed closure with skin staples (odds ratio, 2.91; 95% confidence interval, 1.07-7.94; p = 0.037) as the only independent factor negatively associated with wound complications. Subcuticular sutures appear to reduce wound complications compared to skin staples following repeat incision for liver resection.
