BACKGROUND: The objective of this report was to study the sensitivity of indicators used for predicting bile duct stones and their endoscopic removal before laparoscopic cholecystectomy. @entity1 AND METHODS: A retrospective study was conducted on 104 @entity1 who successfully underwent endoscopic retrograde cholangiopancreatogram (ERCP) before laparoscopic cholecystectomy at Riyadh Medical Complex between 1992 and 1994 (1412H-1414H). Six indicators  @entity1087 , @entity788 , stones in bile duct on sonography, dilated bile duct (>7 mm) on ultrasonography, dilated bile duct with deranged liver function test, and deranged liver function test without @entity1087  were used for suspecting @entity2877 and endoscopic removal before laparoscopic cholecystectomy. RESULTS: Ultrasound correctly predicted bile duct stone in 75%, followed by dilated bile duct with deranged liver function test (46%). @entity1087 and @entity788 were equally sensitive indicators (42% each). Sensitivity of only dilated bile duct on ultrasonography in predicting duct stone was 36%. @entity1578 without @entity1087 was the least sensitive (22%) of the predictors. Overall, these indicators correctly diagnosed bile duct stones in 34% of @entity1 . CONCLUSION: Until laparoscopic exploration of bile duct or a noninvasive technique, such as magnetic resonance cholangiopancreatogram (MRCP), is widely available, these predictors will help in selecting @entity1 with bile duct stones for preoperative removal. Other workers have suggested combining these indicators to improve the predictive value.
