[Choledochal cyst. The clinical picture, diagnosis and therapy].

A 21-year-old woman who for more than one year had had epigastric pain which was unrelated to food and radiated belt-like, was found to have a marked increase in gamma-GT, slightly elevated phosphatase activity, and increased erythrocyte sedimentation rate. The diagnosis of choledochal cyst, type Ia, was confirmed by sonography, endoscopic retrograde pancreatography and intravenous cholangiography. A choledochocystojejunostomy with a Y-Roux anastomosis was constructed to stop the cholestasis and prevent complications. The patient became symptom-free after the operation.
