Abstract
Seventeen cases of rectal carcinoid which were experienced in our hospital were examined and discussed their surgical treatment. The sex ratio was 1: 1 and the mean age was 51.9 years. Carcinoids were located mainly in the range from 5 to 8 cm from the anal verge. Eight of them were 9 mm or less in size, 5 were 10-19 mm and 4 were 20 mm or more. All tumors smaller than 19 mm were sessile in shape and located in the submuscular layer (sm). Polypectomy was performed in 5 cases, local resection in 5 cases, and a radical operation with lymphadenectomy in 7 cases. Five patients with carcinoids smaller than 9 mm underwent polypectomy. 5 with tumors 10-19 mm underwent local resection, and all patients with tumors larger than 20 mm underwent radical surgery. Only 2 patients, with tumors of 50 mm with lymphnode metastasis, died of recurrence. The treatment of a rectal carcinoid must be selected according to its size as follows: polypectomy or local resection for tumors smaller than 9 mm and radical surgery with lymphadenectomy for those larger than 20 mm are recommended. In the case of tumors of 10-19 mm, radical surgery must be decided according to the depth of the carcinoid and invasion to vessels after local resection.
