From 1932 to 1978, 105 patients with biliary enteric fistulas are reported upon from The New York Hospital-Cornell Medical Center. During this 46 year period, 11,808 patients were operated upon for nonmalignant biliary tract disease, representing an incidence of biliary enteric fistulas of 0.9 per cent. The most common location of the fistula was cholecystoduodenal in 77 per cent and cholecystocolic in 15 per cent. Ninety-eight of the 105 patients underwent 109 surgical procedures for symptoms and complications associated with the fistula. The operative mortality was 6 per cent. The recommended definitive procedure includes cholecystectomy, excision of the fistula, common bile duct exploration and operative cholangiography. Among the 105 patients were 22 who presented with intestinal obstruction or ileus due to gallstones. The operative mortality in this group was 4.5 per cent. The recommended treatment for this condition is operative relief of the obstruction with correction of the biliary enteric fistula at an elective second stage operation.
