Aims Challenging perineal defects resulting from extralevator (ELAPE) and standard abdominoperineal excision (APE) have resulted in a growing multidisciplinary approach between colorectal and plastic surgery colleagues. Currently there is a paucity of evidence on best practice in this emerging field. This study aims to define and describe current national practice within the United Kingdom (UK) in perineal reconstruction following APE/ELAPE. Methods A national practice questionnaire was designed using ‘Google Forms' and circulated via email to 41 units across the UK performing perineal reconstruction following APE/ELAPE. Results Complete responses were received from 23 units (response rate 56%), representing 12 regions across the UK. All units had a dedicated APE/ELAPE service. 70% had a standardised approach to reconstruction, with the Inferior Gluteal Artery Perforator (IGAP) flap being the most common approach (n = 11). Significant variation was observed in the reconstructive approach with regards to flap choice and routine use of pelvic acellular dermal matrix or mesh. Similar differences were observed in the perceived importance of various surgical factors that guide the reconstructive decision making process. Conclusions Our national practice questionnaire responses report nationally well established local networks between colorectal and plastic surgeons. However, the variation in results reflects a lack of national consensus on the optimal reconstructive method after APE/ELAPE. Our study highlight the need for the development of collaborative evidence based national guidance on best practice.

Severe malnutrition secondary to anorexia nervosa results in deeper burns and significantly impacts wound healing, which represents a major challenge to burn management. The use of acellular dermal matrices, such as biodegradable temporizing matrix (BTM), is a valuable tool to overcome the surgical limitations. We describe a case of a 36-year-old female with a background of anorexia nervosa (body mass index of 12.3) presenting with a 30% total burns surface area (TBSA) burn. All of her burns were excised down to fascia due to the absence of subcutaneous fat. Her thin skin and depleted nutritional status significantly impacted reconstructive options. BTM was utilized to create a neodermis and provide adequate time to optimize the nutritional status before autologous skin resurfacing 3 weeks later, which yielded robust coverage with minimal donor site morbidity. Despite initial surgical and nutritional challenges, excellent outcomes were achieved in terms of wound healing, scar contractures and mobility.

Dermatofibrosarcoma protuberans (DFSP) is a rare, locally invasive dermal sarcoma. The management is generally surgical, with wide local excision (WLE) forming the mainstay of treatment. Large abdominal wall defects are most aesthetically reconstructed using pedicled or free flaps; however, these require tumour-free surgical margins, and are off-set by donor site morbidity. We describe an alternative, aesthetic and low-morbidity technique for reconstruction of a subfascial defect following WLE of DFSP in a young woman in her early 20s, using two layers of a novel synthetic dermal matrix (NovoSorbBTM). To our knowledge, a double-layer reconstruction using an artificial dermal matrix has never been described for trunk reconstruction. We found that double-layer biodegradable temporising matrix can restore the inherent thickness and pliability of skin in a partial-thickness abdominal wall defect and offers improved durability and cosmesis compared with skin grafting or indeed single layer skin substitutes alone.
