What is the treatment of a colonic carcinoid? What is the treatment of a rectal carcinoid?

For the treatment of colonic carcinoids, most experts suggest a formal hemicolectomy with mesenteric resection as the preferred treatment. Similar to appendiceal carcinoids, the size of rectal carcinoid tumors is closely correlated with metastatic risk and long term survival rates. Rectal carcinoids < 2 cm rarely metastasize. Therefore, for these smaller lesions, local excision is sufficient. For rectal carcinoids larger than 2cm, a low anterior resection (LAR) or abdominal perineal resection (APR) should be performed provided distant metastases are absent.
