title: [Diagnosis and surgical treatment of internal biliary fistula].
abstract: Results of examination and surgical treatment of 172 patients with internal biliary fistula (IBF) are analyzed. IBF was revealed in 0.22% of hospitalized patients with cholelithiasis. There were 4 variants of fistula formation. Combined spontaneous multiple fistula were described for the first time in 8 patients. Based on assessment of IBF's clinical symptoms formula for prediction of IBF development was proposed. Diagnostic potential of instrumental, X-ray, endoscopic and ultrasonic examinations was assessed. Differential surgical policy depending on IBF variant is described.
