Background:
Wound dehiscence (WD) of the anocutaneous anastomosis or perineal body after posterior sagittal anorectoplasty (PSARP) is common. We aimed to evaluate the efficacy of a perineal vacuum-assisted closure (VAC) for prevention of WD following repair of anorectal malformations (ARM) with rectoperineal and rectovestibular fistula.
Methods:
A retrospective dual-center case-control study of children undergoing PSARP without colostomy between 2011 and 2019 was performed. The VAC group received preoperative bowel preparation (PBP), postoperative application of a VAC, loperamide (only Location A), intravenous antibiotics (IA), and total parenteral nutrition (TPN). The non-VAC group underwent PBP, loperamide (Location A), IA, and TPN without VAC. Primary outcome was WD at the anocutaneous anastomosis or reconstructed perineal body within the first 14 days after surgery.
Results:
The study population included 18 patients (VAC group) and 20 children (non-VAG group) with rectoperineal and rectovestibular fistula. The incidence of WD in the VAC group was 0% compared to 25% in the non-VAC group (0/18 vs. 5/20, p = 0.04). No VAC related complications occurred.
Conclusion:
Postoperative application of a VAC embedded in a perioperative treatment protocol has the potential to prevent wound dehiscence of the neoanus and reconstructed perineal body following PSARP.
Type Of Study:
Case-control study.
Level Of Evidence:
Level III.
