The cholangiogram showed that multiple filling defects at the left hepatic duct and the distal bile ducts were dilated (Figure 2). After direct visualization of the cholangioscopy confirming complete damage of the lesions (Figure 4 and Supplementary Video 2), the necrotic tissue was extracted using a basket.
SpyGlass cholangioscopy revealing multiple reddish villous lesions with fine vascular cores on the surface in the left hepatic duct lumen.

Direct visualization revealed multiple reddish villous lesions with fine vascular cores on the surface in the left hepatic duct lumen (Figure 3).
Repeat SpyGlass cholangioscopy confirming no residual villous lesions.
