| [ Summary ] |
To clarify the therapeutic courses of rectal carcinoid, clinico-pathological characteristics of 80 rectal carcinoids resected by endoscopic resection or surgery between 1989 and 2000 were retrospectively evaluated. The results were as follows: 1) The tumors were 10mm or less in 74 lesions (92.5%), 11-15mm in 4 lesions (5.0%), and 21mm or more in 2 lesions (2.5%). 2) The depth of tumor invasion was submucosa in all lesions of 10mm or less in size. 3) Lymph node metastasis was detected in the case of one 15-mm lesion with, tumor invasion of the muscularis propria and lymph vessels.
Endoscopic resection should be considered for tumors 10mm or less in size, and additional surgical therapy should be determined based on histological findings. |
