CLINICOPATHOLOGICAL STUDIES OF OBSTRUCTED COLON CARCINOMAS

In recent years, the incidence of carcinoma of the colon has been increasing. Patients with advanced carcinoma or obstructed colon carcinomas are numerous. There were 156 patients operatd on for colon carcinomas in our department over the past 10 years. Of this group, 19 patients (12.2%) who had large bowel obstruction were analyzed clinicopathologically. In the obstructed group, the lesion was most frequently located in the sigmoid colon and the resection rate of the carcinomas was 84.2%, the curative resection rate, 68.4%. This was little lower than that in the non-obstructed group. There were no significant differences in the pathological findings or in the five-year survival rate of the two groups. Radical surgery in primary or second staged resection is recommended for the management of obstructed colon carcinoma.
