Overview
Ultrasound
- Ultrasounds (US) may show dilation of the bile duct and identifies 38% of bile duct stones.[1]
- It is relatively poor at identifying stones further down the bile duct.
- An ultrasound is the primary imaging modality used to access patients with suspected acute cholangitis.[2]
- It is both sensitive and specific in detecting biliary dilatations.
- An US can show biliary dilatations with or without stones and debris material within the common bile duct.[3]
- However, biliary dilatations are not not always present at early stages of bile duct obsctructions, and the performance of an US in indicating choledocholithiasis is poor.[2]
- For patients who have previously not undergone a cholecystectomy, an US allows doctors to determine patients with high probability of having choledocholithiasis even if the stone is not directly visible on US.[2]
- A main finding of ascending cholangitis on an US is the thickening of the bile duct walls.[3]
- Ultrasound can help distinguish between cholangitis and cholecystitis (inflammation of the gallbladder), which has similar symptoms to cholangitis but appears differently on ultrasound.[1]
