ABSTRACT

Objective To study the surgical treatment of duodenal invasion by cancer of hepatic flexure of (colon). Methods Clinical data of 15 cases of duodenal invasion by cancer of hepatic flexure of colon were analyzed retrospectively.Results Invasion of the second or third portion of the duodenum by cancer of the hepatic flexure of colon occurred in 15 cases.The duodenum was adhered to the cancer in 6 cases,(seromuscular) invasion by the tumor in 5 cases,and duodenocolic fistula in 4 cases. All of the cases received surgical (treatment). 8 cases were mucoid adenocarcinomas, 4 were poorly differentiated adenocarcinomas, two were moderately differentiated adenocarcinomas, and one was signet-ring cell carcinoma. One patient died (after) operation, and the five-year survival rate was 46.7%(7/15). Conclusions Duodenum is the first organ easily to be invaded by cancer of hepatic flexare of colon. Radical and en bloc resection of the colonic cancer and involved organs is the best therapeutic method. The key to recovery is correct treatment of the (surgical) defect of the duodenum.
