Abstract
Following Irwin firstly reported the cancerous change of the congenital choledochal cyst in 1944, the disease has been the object of attention. Until now there are many case reports about the disease, the prognosis is still unsatisfactory because most cases are already past treatment. Then early diagnosis and treatment are eagerly desired. In this paper, we present a case report of early bile duct cancer associated with congenital choledochal cyst detected by ultrasonography and 10 case reports of early bile duct cancer in literature.
Our case underwent pancreatoduodenectomy and after 6 years and 3 months, he is safe and sound. Cases reported were among 18 to 50 years old and including our case,3 cases are male. All the cases but one complained abdominal pain, especially right hypochondralgy.4 cases were accompanied with obstructive jaundice on admission. Preoperatively,8 cases were diagnosed,4 cases were with ERCP and 4 cases were with ultrasonography. Pancreatoduodenectomy was performed in 4 cases while cystectomy were in 7 cases. And 4 cases were deceased (ave.25months after operation) while 7 cases are alive (ave.37 months after operation).7 cases were papillary adenocarcinoma,2 cases were tubullar adenocarcinoma, a case of papillotubullar adenocarcinoma and a case of adenosquamous carcinoma. In cases with congenital dilatation of biliary tracts, we must take care so as not to miss cancerous lesions in our image diagnosis. And ultrasonography is the most helpful in this purpose.
