Video S1 A short-type single-balloon enteroscope (s-SBE) was inserted via the oral route and the stenotic area in the afferent loop was identified. The stenosis was confirmed with contrast medium. A guidewire was used to traverse the stricture, and contrast medium revealed the intrahepatic bile ducts. In view of elevated inflammatory markers, a nasobiliary drainage tube was placed in the afferent loop. The s-SBE was advanced to the site of the stricture via the nasobiliary drainage tube. The guidewire was exchanged via the nasobiliary drainage tube and placed in the intrahepatic bile duct. The stricture was confirmed again with contrast medium. A metal stent was inserted past the stenotic area. The stent was straightened and gradually deployed. When the stent passed the stricture, flow of contrast was confirmed and the stent was left in place.
