[Percutaneous extraction of pigment lithiasis of the choledochus in an infant].

The authors present the first report of a pigment gallstone of the common bile duct in a 2 month-old infant treated in a non-surgical manner. The gallstone extraction was percutaneous, by a small catheter introduced in the biliary tract under ultrasound control. The clinical and ultrasonographic follow-up (19 months) confirmed complete recovery. This new therapeutic modality might avoid surgery for primary common bile duct cholelithiasis.
