| [ Summary ] | In this study, we investigated the ninty nine rectal carcinoid tumors treated at Hiroshima University Medical Hospital and affiliated hospitals between 1977 and 2000. Eighty-six lesions were smaller than 10mm in diameter, and most of these small rectal carcinoids could be removed completely with endoscopic mucosal resection (EMR) or local surgical resection. Metastasis was recognized in six cases. All lesions were larger than 10mm in diameter, and displayed lymphatic vessel invasion. Four of these lesions, were accompanied by central depressions. It may be considered that lesions smaller than 10mm in diameter, confined to the submucosa, without vessel invasion, and without central depression can be completely cured with EMR alone. | |
