AbstractBackground: Perineal wound complications are common after abdominoperineal resection (APR) for rectal adenocarcinoma. Delayed wound healing may postpone postoperative adjuvant therapy and, therefore, lead to a worse survival rate. Negative-pressure wound therapy (NPWT) has been suggested to improve healing, but research on this subject is limited. Methods: The aim of this study was to assess whether NPWT reduces surgical site infections (SSI) after APR for rectal adenocarcinoma when the closure is performed with a biological mesh and a local flap. A total of 21 consecutive patients had an NPWT device (Avelle, Convatec™) applied to the perineal wound. The study patients were compared to a historical cohort in a case–control setting in relation to age, body mass index, tumor stage, and length of neoadjuvant radiotherapy. The primary outcome was the surgical site infection rate. The secondary outcomes were the wound complication rate, the severity of wound complications measured by the Clavien–Dindo classification, length of hospital stay, and surgical revision rate. Results: The SSI rate was 33% (7/21) in the NPWT group and 48% (10/21) in the control group, p = 0.55. The overall wound complication rate was 62% (13/21) in NPWT patients and 67% (14/21) in the control group, p > 0.90. The length of hospital stay was 15 days in the NPWT group and 13 in the control group, p = 0.34. The wound severity according to the Clavien–Dindo classification was 3b in 29% (6/21) of the NPWT group and in 38% (8/21) of the control group. A surgical revision had to be performed in 29% (6/21) of the cases in the NPWT group and 38% (8/21) in the control group, p = 0.73. Conclusion: NPWT did not statistically decrease surgical site infections or reduce wound complication severity in perineal wounds after APR in this case–control study. The results may be explained by technical difficulties in applying NPWT in the perineum, especially in female patients. NPWT devices should be further developed to suit the perineal anatomy before their full effect can be assessed. see all
