Choledochocele demonstrated by computed tomographic cholangiography: report of a case.
Choledochocele is a rare cystic congenital malformation of the distal common bile duct, the precise pathogenesis of which remains unclear. It is usually diagnosed in adulthood after many examinations for unclear digestive symptoms, as in the patient whose case is described herein. Of all the diagnostic techniques available, endoscopic retrograde cholangiography (ERCP) seems to be the best; however, it is an invasive procedure associated with some morbidity. Spiral computed tomographic cholangiography with three-dimensional reconstruction is also an interesting screening technique. Malignant transformation of a choledochocele occurs very rarely, compared with other cystic malformations of the biliary tract. If a choledochocele is small and symptomatic, the lesion can be treated by endoscopic sphincterotomy, but larger cysts are more effectively removed by a surgical cystoduodenostomy. We present herein the case of a 25-year-old woman admitted to our hospital in March 1998 with upper right quadrant abdominal pain caused by a choledochocele, who was successfully treated by a cystoduodenostomy.
