title: [Value and sensitivity of abdominal ultrasound in preoperative histologic diagnosis before laparoscopic cholecystectomy].
abstract: In a retrospective study we compared the findings of our abdominal ultra-sound diagnostic of the gallbladder and the common bile duct with the results ot preoperative ERCP, intraoperative findings and the histological results. The test parameters were the size of the gallbladder, the number and the size of biliary calculi, the thickness and the constitution of the wall of the gallbladder and the consecutive grade of inflammation, the wideness of the common bile duct and the suspicion of a choledocholithiasis, respectively. In acute cholecystitis we performed laparoscopic cholecystectomy within 24 hours, in symtomatic cholecystolithiasis without cholecystitis an elective laparoscopic cholecystectomy. If there was suspicion of a choledocholithiasis we performed a preoperative ERCP. Altogether we had correct findings of the common bile duct in our ultrasound diagnostic in 133 of 136 cases (97.8%), only in 3 of 136 cases (2.2%) we had false negative ultrasound findings. With a generous indication to ERCP caused by anamnestic and/or laboratory findings the obstruction of the bile duct could be diagnosted and eliminated in 2 of these 3 cases preoperatively. In all cases of bile duct dilatation (7 mm and more) we found an obstruction of the common bile duct. Our results demonstrate that abdominal ultrasound is a high-efficiency method in the preoperative diagnostic of gallbladder and common bile duct stones.
