The role of Intraoperative cholangiography (IOC) and methylene blue tests in reducing bile leakage after living donor hepatectomy

Abstract

Aim: Liver transplantation remains the only curative treatment in end stage liver disease. Biliary complications remain the most common major morbidity causes in hepatic resection. We aimed to determine and eliminate the bile leakage in donor hepatectomy of LDLT. Material and methods: This study was conducted retrospective and one center study. The study population included 110 consequential liver donors with major liver resection (more than three segments). The population was divided into three groups for data analyses. Primary study groups included 40 donors subjected to methylene blue test starting in April 2013 and 40 donors subjected to intraoperative cholangiography started in March 2014. Results: A total of 110 liver donors (42.7% women) were included in the study. Postoperative biliary complications were less in methylene blue and intraoperative cholangiography (IOC) groups. Bile leakage was significantly higher in control group (23.3%) compared to methylene blue (5%) and IOC groups (2%) Average duration of hospital stay and duration of operation were significantly higher in control group compared to methylene blue and IOC groups. Conclusion: In our study we conducted to establish biliary leakage in living donor hepatectomy which intraoperative cholangiography test was used to determine. Many intraoperative methods have been introduced to prevent biliary leakage and development of complications. We have showed that IOC test used in the present study could be easily applied in both living liver donor hepatectomy and other major hepatectomy cases. IOC test reduced postoperative biliary leakage incidence and did not increase incidence of other complications.
