Abstract
Carcinoid tumors arise from enterochromaffin cells that are located predominatly in the gastrointestinal mucosa. The vast majority of rectal carcinoid tumors are benign and can be safely treated by local excision. Lesions larger than 2 cm and invading the museular wall of the rectum should be considered malignancy and treated by more radical surgery such as abominoperined resection. We report 6 cases of rectal carcinoid tumor, three cases of them were less than 1 cm in size without metastasis. Two of these, small carcinoid tumor were treated with endoacopic polypectomy and one was treated with segmental resection. The others were 2.0 cm or larger in size with regional or liver mestasis. They were treated with segmental resection or electrical fugalization for tumor and transcatheter arterial embilization for liver metastasis or none.
