Abstract
BACKGROUND: Abdominoperineal resection is used to treat a variety of colorectal pathologies. Traditionally, the vertical rectus abdominis myocutaneous flap has been most commonly used for reconstruction. Here, we explore the role of the profunda artery perforator (PAP) flap for perineal reconstruction.METHODS: A prospectively maintained database was retrospectively analyzed to identify patients who had undergone perineal reconstruction with a pedicled PAP flap. Parameters of interest included age, sex, body mass index, primary diagnosis, comorbidities, and history of radiation, and postoperative complications.RESULTS: Fifteen patients (5 men and 10 women) with a median age of 52 years (interquartile range, 48.5-61.5 years) were included in the study. Median body mass index was 26.3 kg/m2 (interquartile range, 24.0-29.3 kg/m2). Patients underwent abdominoperineal resection for treatment of rectal cancer (n = 9, 60.0%), recurrent anal squamous cell carcinoma (n = 3, 20.0%), and Crohn's disease (n = 3, 20.0%). Twelve patients (80.0%) underwent neoadjuvant radiotherapy. Eight patients (53.3%) experienced a total of 10 complications (2 major and 8 minor). The most common complication was donor (n = 3, 20.0%)/recipient (n = 3, 20.0%) site wound dehiscence. Stable soft tissue coverage was achieved in all patients.CONCLUSIONS: The PAP flap provides stable soft tissue coverage of perineal defects with a low donor-site morbidity. This flap should be strongly considered in the reconstructive algorithm when approaching perineal defects.
