Summary
Percutaneous transhepatic cholangiography using the CHIBA needle visualized the biliary system in most patients. This minimally invasive technique proved effective and accurate for diagnosing various biliary tract conditions.
Area of Science:
- Medical Imaging
- Gastroenterology
- Interventional Radiology
Background:
- Biliary system visualization is crucial for diagnosing various hepatobiliary diseases.
- Percutaneous transhepatic cholangiography (PTC) offers a direct approach to the biliary tree.
Purpose of the Study:
- To evaluate the diagnostic utility and safety of percutaneous transhepatic cholangiography using the CHIBA needle method.
- To assess the accuracy of PTC in diagnosing biliary tract pathologies.
Main Methods:
- The CHIBA needle method for percutaneous transhepatic cholangiography was performed on 15 patients.
- Radiological assessment of the biliary system was conducted post-procedure.
Main Results:
- Successful visualization of the biliary system was achieved in 93.3% of cases.
- Diagnoses included Klatskin tumors, papillary carcinoma, terminal choledochus carcinoma, intrahepatic neoplasia, and post-traumatic stenosis.
- Minor complications such as biliary colic, transient bacteremia, and small hepatic contrast leakage were observed.
Conclusions:
- Percutaneous transhepatic cholangiography with the CHIBA needle is a simple, cost-effective, and accurate diagnostic tool.
- The technique is highly useful for evaluating complex biliary system pathologies.
