A Case of a 25mm Nodular Aggregated Type sm Carcinoma Resected en bloc by the Method of Strip Biopsy

Abstract

The Patient, a 65-year-old man, was found by a barium enema X-ray study to have type 2 advanced carcinoma of the cecum and an elevated lesion in the splenic flexure.
He was admitted to our hospital on July 1, 1992. Colonoscopic examination revealed that the cecum had a type 2 advanced lesion and the splenic flexure a nodular aggregated type lesion, both of which were classified as group V when biopsies were taken.
On July 13, colonoscopic examination was made again and the nodular aggregated type lesion was resected en bloc by the method of strip biopsy, removing a block of tissue 31mm wide including normal mucosa. The lesion measured 25mm×19mm and was classified as highly differentiated sm₁ adenocarcinoma. Typical surgery could be performed with success on a patient with a type 2 advanced carcinoma of the cecum without resort to colectomy which would have involved extensive resection.
