J Coll Physicians Surg Pak Jan ;10(5):173-4.
During the period of one year i.e. from January, 1996 to December, 1996, Intraoperative Ultrasonography, using a 7.5 MHz linear transducer, was carried out in a series of 46 patients undergoing open cholecystectomy at Surgical Unit 1 of Civil Hospital, Karachi, to assess common bile duct for stones. On the basis of scanning a correct diagnosis of choledocholithiasis was made in 85.7% cases while common bile duct stones were excluded correctly in 100% of the cases. Mean extra-time required was 17 minutes. There was no procedure-related increase in morbidity and overall mortality was 0%. Operative ultrasonography Is a safe and reliable screening method for common bile duct stones.
