Bottom Line: In the second case of middle bile duct stricture due to lymph node metastases from gallbladder cancer, a stent was placed in the bile duct across the stenosis.No procedure-related complications were observed.Unevenness of the outer surface and a low shortening ratio are expected to lessen the occurrence of complications characteristic of covered metal stents such as stent migration and bile duct kinking.

ABSTRACT
We herein report two patients with unresectable malignant biliary stricture who underwent stenting with a newly developed fully-covered metal stent. In the first case of lower-middle bile duct cancer, a stent was placed through the stenosis. In the second case of middle bile duct stricture due to lymph node metastases from gallbladder cancer, a stent was placed in the bile duct across the stenosis. No procedure-related complications were observed. Unevenness of the outer surface and a low shortening ratio are expected to lessen the occurrence of complications characteristic of covered metal stents such as stent migration and bile duct kinking.

Endoscopic retrograde cholangiography. ERC revealed a stricture (arrow), 1.5 cm in length, in the middle bile duct (a). A covered Zeostent (arrow), 6 cm in length and 1 cm in diameter, was placed in the bile duct  across the stricture following sphincterotomy (b).

Mentions: Based on the diagnosis of gallbladder cancer with lymph node metastases, transpapillary biliary stenting was attempted after obtaining written informed consent. ERC revealed a stricture, 1.5 cm in length, in the middle bile duct (Figure 3(a)). A covered Zeostent, 6 cm in length and 1 cm in diameter, was inserted into the bile duct across the stricture and the cystic duct up to the upper bile duct following sphincterotomy (Figure 3(b)). There were no clinical symptoms suggesting complications such as pancreatitis and cholecystitis. The placed stent was fully expanded the day after the procedure. Stent migration and other complications were not observed during the four-month followup period.
