RAPID RECURRENCE OF SIGMOID COLON CANCER AFTER ENDOSCOPIC RESECTION-A CASE-REPORT-

Abstract

Criteria for endoscopic resection of early colon cancer have been established in Japan. However, some cases can not undergo additional surgical resection after endoscopic resection because of poor general condition. Sometimes there is rapid recurrence of the tumor. A man who had been hospitalized for liver failure, was diagnosed as having early sigmoid colon cancer and endoscopic mucosal resection was performed. Additional resection was recommended because pathology showed tumor invasion near the cut margin, but the poor condition of this patient prevented further surgery. Although there was no recurrence 3 months after the resection, advanced cancer was detected at the stump of the excisional site by endoscopy 15 months after resection. More frequent endoscopic surveillance after the resection should be needed for lesion with tumor invasion near the cut margin.
