Definition / general
  • Biliary enteric fistulas found in 0.2 to 5.0% of patients with biliary tract surgery for nonmalignant disease (Surgeon 2010;8:67)
  • 90% due to cholelithiasis, 10% due to penetrating peptic ulcers of stomach or duodenum
  • Complications: gallstone ileus
  • Mortality: 15%
Sites
  • From gallbladder in 90%, biliary tract in 10%
  • Usually to duodenum, also colon
Pathophysiology
