We report two cases of benign biliary strictures managed by metallic stent placement because the patients refused surgical repair. One patient is a 67-year-old man who had a stricture of the right hepatic duct and a bile leak following a cholecystectomy. The second patient is a 50-year-old man who had a stricture of the left hepatic duct following a right hepatic lobectomy for hepatolithiasis. For treatment of these bile duct strictures, a Gianturco-Rosch Z stent was placed in the former case and a Wallstent in the latter. Luminal patency of the stent was maintained for 7 years in the former case but in the latter, luminal stenosis of the stent was induced soon after placement. However, in the former, bile stasis in the left hepatic duct system, which emptied into the side of the stent, gradually developed without signs or symptoms of cholangitis or biliary obstruction. Therefore, the use of metallic stents for benign biliary stricture remains controversial. However, if metallic stent placement is the only therapeutic option, it is necessary to maintain bile flow not only through the stent but also in the bile ducts which flow into the side of the stent.
