Resection of Neoplastic Disease

Anal carcinoma - small lesions (< 2 cm) present at the anal verge are usually treated by local excision with a 2 cm margin of skin around the tumour. The resection should extend down to the perianal fat. For larger tumours, or extensive tumours of the anal canal that are unresponsive to radio-/chemotherapy, abdominoperineal resection is the procedure of choice. A 2 cm margin of perineal skin should be excised around the tumour and there should be a radical ischiorectal resection. If there is metastatic spread to superficial inguinal nodes then a radical groin dissection may be considered.
