Fig 1.
A case of bilateral metal stenting for malignant hilar obstruction.
a. Fluoroscopic view with bilateral nasobiliary drainage; b. After biliary cannulation, two 0.025-inch guidewires were placed in the left and right hepatic duct; c. The first stent was deployed in the left duct, and the remaining guidewire was inserted through the cell of the left stent with the guidewire in the right duct as the reference; d. A catheter was introduced to confirm resistance and to evaluate the right duct again; e. The second stent was then deployed as the stent-in-stent method.
