Preoperative Drip Infusion Cholangiography With Computed Tomography to Identify the Duct of Luschka in Living-Donor Hepatectomy: A Case Report.

The Duct of Luschka represents a rare form of accessory biliary ducts. There are no reported cases of the Duct of Luschka in living donor hepatectomy. We report a 36-year-old man with the Duct of Luschka who underwent living-donor hepatectomy. Preoperative drip infusion cholangiography with computed tomography (DIC-CT) identified the Duct of Luschka originating from the right hepatic duct to the cystic duct. By choosing the left and caudate lobe hepatectomy, the Duct of Luschka was left intact during the procedure. The donor recovered uneventfully posthepatectomy, and the recipient also did not experience biliary complications. This case underscores the importance of preoperative DIC-CT and surgical planning, including graft selection, to prevent postoperative bile leaks.
