Wound healing after surgery for soft tissue sarcomas, and the effect of primary plastic reconstruction - A...

Immediate vascularized reconstruction after sarcoma resection may reduce wound complications common in primary closure, but previous research is conflicting. The present study analysed wound complication rates and compared wound-related outcomes among immediate vascularized reconstruction with primary closure.

Patient- and tumour characteristics were collected from patients who received primary surgery with curative intent between 2010 and 2020 at the Stockholm Sarcoma Centre. Clinical outcomes were sought in free text in medical records. The primary outcome measures were early (<30 days) wound complications. Secondary outcome measures included late (30-day to 2-year) wound complications, time to wound healing, 30-day postoperative complications according to Clavien Dindo, and health care consumption.

A total of 482 patients were included, of whom 69 had immediate vascularized reconstruction. Comparison of early complications for reconstructive surgery with primary closure revealed a significantly higher complication rate for the first group (59.4 % vs 29.8 %, p < 0.01). The groups had comparable health care consumption the first and second postoperative years. In-depth analyses identified BMI >25, smoking and high-grade lesions as factors with adverse effects on wound healing.

Sarcoma patients experience high rates of wound complications and consume considerable health care resources. Reconstructed individuals were more susceptible to such complications than were subjects with primary closure.
