Successful Removal of a Stone and an Expandable Metallic Stent from the Biliary Tract of a Patient with Acute Occlusive Pyogenic Cholangitis

抄録

We removed a biliary stone and the metallic stent placed two years previously in a patient with benign biliary strictures.
An 80-year-old woman who had been inplanted with an expandable metallic stent (EMS) to prevent obstruction by a large common bile duct stone about two years before as an emergency measure in another hospital, was afficted with acute occlusive pyogenic cholangitis (AOPC) and hospitalized in our hospital. After treating the AOPC, we successfully removed the EMS with a cholangioscope and normal biopsy forceps through the percutaneous transhepatic channel under fluoroscopy.
The type of the EMS was Accufulex^® stent. To remove it was easier than expected. Once it started to unravel, it was removed from the common bile duct within a few minutes.
