A National Survey on Perineal Reconstruction Following Standard and Extralevator Abdominoperineal Excision: Current Practices and Trends in the UK

Background Challenging perineal defects resulting from extralevator (ELAPE) and standard abdominoperineal excision (APE) have given rise to an emerging multidisciplinary approach between colorectal and plastic surgeons. At present, there is a relative paucity of evidence on best practice. This study sought to assess current national practice concerning perineal reconstruction following APE/ELAPE in the United Kingdom (UK) and to determine the factors involved in reconstruction choice. Methodology An anonymised survey was circulated to consultant plastic surgeons at all 48 UK centres performing perineal reconstruction following APE/ELAPE. Responses were collected between October 2021 and April 2022. Results Complete responses were received from 24 units nationally. All units had a dedicated APE/ELAPE service. Overall, 70% adopted a standardised reconstructive approach, the most common being the inferior gluteal artery perforator flap (n = 11). Significant variation was identified in the reconstructive technique. Similar differences were observed in the perceived importance of surgical factors guiding the reconstructive decision-making process, the top priorities being the size of the defect and previous radiotherapy. Conclusions The variability of responses suggests a lack of national consensus on optimal reconstruction following APE/ELAPE, despite the majority of centres employing a standardised approach to reconstruction. Our study highlights important surgical decision-making factors and provides valuable insight to aid in developing national collaborative evidence-based guidelines on best practice.
