Pelvic floor reconstruction with a biological mesh after extralevator abdominoperineal excision leads to few perineal hernias and acceptable wound complication rates with minor movement limitations: single-centre experience including clinical examination and interview

Abstract

Aim: The aim of the study was to describe long-term subjective and objective results of pelvic floor reconstruction using an absorbable biological mesh after extralevator abdominoperineal excision (ELAPE) for low rectal cancer.

Method: Records of 53 patients who had an ELAPE with reconstruction of the pelvic floor with a Permacol® mesh between August 2007 and August 2011 were reviewed. Thirty-one of the patients were called for interview and clinical examination.

Results: Three (6%) patients developed perineal hernia, 11 had fistulae (nine of which were treated successfully), four patients had a perineal abscess and four patients had superficial wound infections. Removal of the mesh was necessary in one case, while another patient needed implantation of a new mesh. In 13 of the 31 interviewed patients, long-term pain was present, but resolved after a median of 8 months (3-56). No major sitting or movement disabilities were encountered. Three-year survival was 82%, and no local recurrences were found.

Conclusion: Pelvic floor reconstruction with a biological mesh is a feasible solution when performing ELAPE for low rectal cancer, although long-term pain is a frequent complication.
