The abdominoperineal resection is a surgical procedure which implies the removal of rectum, anal canal and the creation of a terminal colostomy. The most frequent complications of this type of surgery are haemorrhage, surgical wound complications, persistent perineal sinus and perineal hernia. Intraoperative haemorrhage or contamination and neoadjuvant radiotherapy are risk factors for the development of perineal complications. Perineal wound infection, with subsequent healing delay, has multifactorial aetiology and its incidence can reach up to 66% according to literature. The prevention of these complications requires adequate surgical technique to avoid or minimise the known risk factors. The treatment of a perineal wound complication depends on the clinical and radiographic findings. When there is no wound resolution in 6 months, it is considered a persistent sinus and treatment will probably require a flap. Several options of surgical treatment are available however, there are no randomised studies to determine which one is the best.
