| Abstract: | In this study, we describe the successful removal of a biliary nitinol metallic stent during percutaneous transhepatic cholangioscopy (PTCS) after lithotripsy of stones caused by obstruction of a metallic stent placed to alleviate stenosis of the choledochoduodenal anastomotic site in a case of benign biliary disease. Using serrated‐edge forceps, one third of the metallic stent was removed in piecemeal sections and then the remaining portion of the stent was removed in one piece through the percutaneous transhepatic fistula. The endoscope was not damaged because all stent materials were removed through the PTCS fistula, not the channel of the endoscope. There were no procedural complications excluding minor bleeding seen endoscopically and no residual stent wires on cholangiograms. In conclusion, this technique is a useful method for metal stent removal from patients in whom it is to extract metallic stent by peroral endoscopic treatment. |
