摘要：COMMON BILE DUCT LITHIASIS OCCURS IN 10-15% OF THE PATIENTS HAVING GALLSTONES. POSITIVE PREOPERATIVE DIAGNOSIS OF COMMON BILE DUCT LITHIASIS CAN ONLY BE DONE BY IMAGING INVESTIGATIONS.POSITIVE FINDINGS USING ANY OF THE ESTABLISHED METHODS SHOULD LEAD TO THE REFERRAL OF THE PATIENT FOR THERAPEUTIC INTERVENTION.NEGATIVE RESULTS IN TRANSABDOMINAL ULTRASOUND OR CT SCANS SHOULD BE FURTHER INVESTIGATED BY MAGNETIC RESONANCE CHOLANGIOGRAPHY OR ENDOSCOPIC ULTRASONOGRAPHY.DUE TO ITS MORE INVASIVE NATURE AND ITS ASSOCIATED MORBIDITY AND MORTALITY RISKS, ENDOSCOPIC RETROGRADE CHOLANGYOPANCREATOGRAPHY SHOULD ONLY BE USED FOR DIAGNOSIS PURPOSES IN SELECTED CASES OR WHEN MAGNETIC RESONANCE CHOLANGIOGRAPHY OR ENDOSCOPIC ULTRASONOGRAPHY ARE NOT AVAILABLE.
