Clinicopathological Study on 14 Laparotomized Cases of Carcinoid of the Colon

Clinicopathological analyses were made on 14 laparotomized cases of carcinoid of the colon. Although the diagnosis is done by the color, form, hardness and biopsy, the existence in the submucosal layer makes the jedgement of the invasiveness difficult. As the result, the method of excision is decided by the size and the location. The lesion in the right colon is apt to be delayed in the diagnosis with the result that it tends to be operatively resected. As for the lesion in the rectum, it usually is resected with a colonofiberscope when the size is less than 1 cm. When the size is over 1 cm., it has to be resected locally, by perineal resection or by laparotomy. When the size is over 2 cm., it must be definitely resected by laparotomy. However, when it is between 1 to 2 cm. and the invasion is over submucosal layer, it has to be managed carefully because the lesion has the possibility of lymphatic matestasis.
