[Interdisciplinary diagnosis of choledochus cysts]

Area of Science:

• Gastroenterology
• Radiology
• Hepatology

Background:

• Cystic dilatations of the biliary tract are rare congenital anomalies.
• Diagnosis can be challenging due to non-specific symptoms.

Observation:

• Eight patients with biliary tract dilatations were evaluated using various diagnostic methods.
• Common symptoms included non-specific upper abdominal discomfort and intermittent jaundice.

Findings:

• Sonography is a primary non-invasive tool for visualizing intra- and extrahepatic biliary duct dilatations.
• Endoscopic retrograde cholangiopancreatography (ERCP) and percutaneous transhepatic cholangiography (PTC) precisely demonstrate biliary anomalies.
• Computed axial tomography (CAT) scanning complements sonography; intravenous cholegraphy is less effective.

Implications:

• Sonography was crucial in diagnosing five patients, while ERCP was definitive in all eight.
• Functional hepatobiliary scanning serves as an alternative when endoscopic procedures are not feasible.
• Accurate diagnosis of biliary tract anomalies is essential for appropriate patient management.
