Cholecysto-urachal fistula

Unusual complications of gallstones

Extrinsic compression of the bile duct from gallstone disease is associated with bilio-biliary fistulization, requiring biliary-enteric reconstruction. Biliary-enteric fistulas are associated with intestinal obstruction at various levels. The primary goal of therapy is relief of intestinal obstruction; definitive repair is performed for selected patients. Hemobilia from gallstone-related pseudoaneurysms is preferentially controlled by selective arterial embolization. Rapidly increasing jaundice with relatively normal liver enzymes is a diagnostic hallmark of bilhemia. Acquired thoraco-biliary fistulas are primarily treated by percutaneous and endoscopic interventions.
