Donor Postoperative Biliary Complications After Living-Donor Liver Transplant

摘要

Objectives: Although the main factors responsible for donor deaths after living-donor liver transplant are liver failure and sepsis, the most common donor complications are associated with the biliary tract. Materials and Methods: Between April 2006 and May 2012, five hundred ninety-three donors underwent living-donor hepatectomy procedures for living-donor liver transplants. The mean age of donors was 31.0 ± 9.9 years and the ratio of men to women was 341:252. Of all donors, 533 (89.9%) underwent a right lobe hepatectomy, 45 (7.6%) underwent a left lateral segmentectomy, and 15 (2.5%) underwent a left hepatectomy. Results: Biliary complications were observed in 51 liver donors (8.6%). Based on the Clavien-Dindo classification, grade I and grade II complications were 3.2% and 0%, while grade IIIa and grade IIIb complications were observed in 3.5% and 1.85% of cases. Right lobe donor biliary complications occurred at the rate of 8.2% in 44 donors. Grade IV and grade V complications were not observed. Grade IIIa complications necessitating radiologic and endoscopic procedures were observed in 21 liver donors (3.5%). Bile leakage unresponsive to medical therapy was detected in 19 donors (3.2%). Nasobiliary catheters were placed in 3 of 19 donors and internal stents were placed in 1. Two sessions of balloon dilatation were performed in the 2 grade IIIb donors (0.33%). Biliary strictures observed in 2 right lobe donors and 1 left lobe donor was treated by hepaticojejunostomy an average of 14 months after surgery. Conclusions: Avoidance of intraoperative issues and early recognition of bile leakage are fundamental in preventing complications in living-donor liver transplant donors.
