Non-invasive imaging techniques such as ultrasound (US) or computed tomography (CT) are widely used for the diagnosis and monitoring of many pancreatic and biliary tract diseases. However, these techniques have limitations, such as the low sensitivity of ultrasound for detecting common duct calculi, which means that the diagnosis of several common conditions including tumours (benign and malignant), calculi, sclerosing cholangitis and chronic pancreatitis may still require invasive procedures such as endoscopic retrograde cholangiopancreatography (ERCP) or percutaneous transhepatic cholangiography (PTC).
These invasive techniques also have disadvantages
for example, ERCP
requires direct cannulation of the common bile or pancreatic duct,
sedation, the use of ionising radiation and a team of trained, experienced personnel. Complications include haemorrhage, sepsis, pancreatitis, bile leakage, as well as a recognised
mortality.1 ERCP may not be technically possible and this,
along with the complication rate, has been related to operator
experience.2 In clinical practice these
complications are usually
