Duct of Luschka Bile Leak Following Deceased Donor Liver Transplant

Patient: Female, 41-year-old Final Diagnosis: Primary sclerosing cholangitis Symptoms: Abdominal pain Medication:— Clinical Procedure: — Specialty: Transplantology OBJECTIVE: Unusual or unexpected effect of treatment BACKGROUND: Biliary leak is a relatively uncommon but potentially severe complication of liver transplantation. Duct of Luschka (also known as subvesical bile ducts) is a term that refers to a number of accessory biliary ducts. While leaks from Ducts of Luschka are well-described in the field of hepatobiliary surgery, only 2 case reports of such leaks exist in the setting of liver transplant. CASE REPORT: We report the first case of a Duct of Luschka biliary leak seen after DCD liver transplant in a 41-year-old woman with cirrhosis secondary to primary sclerosing cholangitis. The patient underwent surgical re-exploration in the immediate postoperative period due to bilious output from a surgical drain. A Duct of Luschka was found intraoperatively at the gallbladder fossa and was oversewn. Apart from immunosuppression-related neutropenia, the patient recovered uneventfully. CONCLUSIONS: Given the variability in preoperative detection of subvesical bile ducts, accessory bile duct leak remains an important consideration in the liver transplant perioperative period. The prevalence of Ducts of Luschka and the relative risk of leakage from such subvesical bile ducts in liver transplants compared to cholecystectomies are unclear. Further research into anatomical accessory bile duct variants and preoperative techniques for detecting such ducts is warranted.
