[Instrumental dilation and transparieto-hepatic cholangioscopy for stenosis of a choledocho-duodenal anastomosis with gallstone formation].

A 94-year old woman presented with gallstone formation above a stenotic choledoco-duodenal anastomosis, responsible for episodes of cholangitis. After percutaneous biliary tract drainage, the anastomosis was dilated with an angioplasty catheter. As several stones persisted despite washing out, percutaneous cholangioscopy was performed. To introduce a small fibroscope into the biliary canals, transhepatic dilation up to 28 F was necessary. The last stones were pushed into the duodenum with the endoscope. Freedom of the biliary tract and patency of the anastomosis were ascertained.
