OLT: orthotopic liver transplantation. Bile duct expansions for UR: unknown reasons. Papillary precut: a needle-like knife was used to cut layer by layer from 11 o’clock position of the papillary uplift highest point to papillary openings, or a needle-like knife was vertically used to pierce and fenestrate via the highest point of the papillary highest bump.
