A transabdominal ultrasound is the initial test of choice in patients with suspicion of ascending<unk>  to detect common bile duct stones or dilatation. USG is both sensitive and specific in detecting bile duct dilatation yet has a lower sensitivity for detecting bile duct stones. However, bile duct dilatation is not always seen in initial stages of bile duct obstruction making it less reliable. The main finding of ascending<unk>  on an ultrasound is the thickening of the bile duct walls
