Ultrasound in choledocholithiasis.
Twenty-five patients of obstructive jaundice due to choledocholithiasis, were prospectively evaluated by ultrasonography and cholangiography. Ultrasound could demonstrate choledocholithiasis in 10 patients (40%). Choledocholithiasis in non-dilated ducts could be demonstrated only in one patient. All cases were diagnosed by cholangiography. Ultrasound, though an accepted modality of choice for diagnosing cholelithiasis, has a limited role in the diagnosis of choledocholithiasis. Ultrasonography (USG) is the screening modality of choice to distinguish obstructive from non-obstructive jaundice. It is highly accurate in the diagnosis of cholelithiasis but its role in detection of choledocholithiasis is less clear. Choledocholithiasis complicates 10% of all cases of cholecystitis and occurs in 2-4% of postcholecystectomy patients. The present study deals with the diagnostic value of USG in cases of choledocholithiasis subjected to USG prior to cholangiography and surgery.
