PURPOSE: Porcine acellular dermal matrix (PADM) has been promoted as a suitable material for the reinforcement of the abdominal wall in Ventral Hernia Working Group (VHWG) Grade 3/4 wounds by Ventral Hernia Working Group et al. (Surgery 148(3):544-548). We describe our experience of, and assess the mechanisms for the failure of PADM (PermacolTM) in intestinal and abdominal wall reconstruction (AWR) for enterocutaneous fistulation (ECF).
METHODS: All patients referred to our unit who had PADM used for AWR and ECF were studied from a prospectively maintained database. Follow-up data until 31/12/2018 were analysed. PADM was explanted at further surgery and examined histologically.
RESULTS: 13 patients, (median age-58.5 years) underwent AWR with PADM reinforcement. Twelve of these (92%) patients had developed abdominal wall defects (AWD) and ECF following complications of previous surgery. Six patients underwent fistula takedown and AWR with PADM, of which 5(83%) refistulated. Seven patients referred to us had already undergone similar procedures in their referring hospitals and had also refistulated. Median (range) time to fistulation after AWR with PADM was 17 (7-240) days. In all cases, PADM had been used to bridge the defect and placed in direct contact with bowel. At reconstructive surgery for refistulation, PADM was inseparable from multiple segments of small intestine, necessitating extensive bowel resection. Histological examination confirmed that the PADM almost completely integrated with the seromuscular layer of the small intestine.
CONCLUSION: PADM may become inseparable from serosa of the human small intestinal serosa when it is left in the abdomen during reconstructive surgery. This technique is associated with recurrent intestinal fistulation and intestinal failure and should be avoided if at all possible.
