A CASE OF BENIGN TUMOR IN THE ADULT GALLBLADDER WITH CONGENITAL CYSTIC DILATATION OF THE COMMON BILE DUCT

Abstract

A 40-year-old woman was admitted to our hospital with the chief complaint of right hypochondralgia. Biochemically, there were no abnormal findings, but D. I. C, CT scan, and abdominal echography showed a tumor of the gallbladder and dilatation of the common bile duct. Then, E. R. C. P. was performed and the diagnosis was confirmed as a tumor of the gallbladder and cystic dilatation of the common bile duct with an abnormality in the union between the choledochus and the main pancreatic duct. (The main pancreatic duct 15 joined with the common bile duct just below the site of cystic dilatation and both the ducts form a long common terminal duct entered at the major papilla of Vater) . Cholecystectomy and choledochotomy were performed. Microscopically, the tumor of the gallbladder was an inflammatory polyp without evidence of malignancy, and choledochus showed no abnormal findings. The patient recovered completely after the operation. Finally, abdominal echography was assumed to be valuable in the differential diagnosis of gallbladder tumors and stones.
