A Case Report of Transverse Colon Carcinoma with Jejunocolic and Colocolic Fistula

Abstract

A 70-year-old man who visited our hospital because of watery diarrhea and body weight loss he was diagnosed as having transverse colon cancer invaded the jejunum and sigmoid colon with enterocolic fistula formation. Left hemicolectomy (D3) and partial resection of the jejunum were performed. The transverse colon cancer had invaded the jejunum and the sigmoid colon to form a cancerous fistula connecting to the three different organs. Histopathological diagnosis was mucinous carcinoma with moderately differentiated tubular adenocarcinoma, classified as pSI (jejunum/sigmoid colon), pN0, sH0, sP0, cM0 Stage II. No relapse or metastasis has been detected for 5 years after the surgery. We believe that favorable prognosis can be expected in cases of colon cancer complicated by internal fistula, by performing a series of aggressive curative resections of the involved organs. We present the case a with literature review that incorporates the views shown there.
