(a, b) Endoscopic retrograde cholangiography; (c) duodenoscopy; (d) fluoroscopy. ERC revealed strictures (arrows), 4 cm in length, in the lower-middle bile duct (a). A fully-covered metal stent (arrows) (covered Zeostent), 8 cm in length and 1 cm in diameter, was placed through the papilla of Vater and the stricture (b, c). The stent was fully expanded the day after the procedure (d).

 Endoscopic retrograde cholangiography (ERC) revealed a strictures, 5 cm in length, in the lower-middle bile duct (Figure 1(a)). Tokyo, Japan) (Figure 2), 8 cm in length and 1 cm in diameter, was placed through the stricture (Figures 1(b) and 1(c)). There were no clinical symptoms suggesting development of pancreatitis. The placed stent was fully expanded the day after the procedure (Figure 1(d)).

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).

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)).
