title: Risk factors for biliary complications after living-donor liver transplant: a single-center experience.
abstract: OBJECTIVE
  Biliary complications remain a major concern in living-donor liver transplant. They can lead to patient and graft loss. In this study, we retrospectively analyzed patients' records to identify factors that increase the frequency of biliary complications in living-donor liver transplant with an aim toward decreasing this frequency.
  
  
  METHODS
  We performed 53 living-donor liver transplants between November 2002 and September 2007. Five cases were excluded because of graft or patient loss within 2 weeks resulting in 48 cases available for analysis. The effect of the following variables on the frequency of biliary complications was analyzed: recipient age, liver lobe used, number of graft bile ducts, number of biliary anastomoses, type of biliary anastomosis, and bile duct diameter 4 mm or smaller.
  
  
  RESULTS
  Biliary complications were seen in 14 cases (29.1%). These included 9 biliary strictures, 3 bile leaks, and 2 bile leaks eventually healing as biliary strictures. The presence of more than 1 graft bile duct increased the frequency of biliary complications (P = .03). The other variables did not have a statistically significant effect on the frequency of biliary complications.
  
  
  CONCLUSIONS
  The rate of complications in our experience is comparable to that already published. The presence of more than 1 bile duct in the graft is a risk factor for biliary complications in living-donor liver transplant. A review of the data suggests additional risk factors.
