Percutaneous transhepatic biliary drainage. Series with a technical note
Diagnostic Imaging in Clinical Medicine
|January 1, 1986
Summary
Simultaneous barium duodenography and percutaneous transhepatic cholangiography aids biliary drainage in challenging cases. This combined imaging approach offers benefits in developing economies lacking advanced imaging technology.
Area of Science:
- Radiology
- Gastroenterology
- Interventional Radiology
Background:
- Percutaneous transhepatic biliary drainage (PTHBD) is crucial for biliary obstruction.
- Visualizing the duodenum during PTHBD can be challenging, especially in complex cases.
- Developing economies often lack access to advanced cross-sectional imaging modalities.
Observation:
- Barium duodenography was combined with percutaneous transhepatic cholangiography in 11 patients.
- This approach was used when standard transhepatic visualization of the duodenum failed prior to PTHBD.
- No complications were reported related to the duodenography procedure.
Findings:
- The combined technique successfully visualized the duodenum in patients with prior failed attempts.
- This modification provides guidance for PTHBD.
- It also facilitates other percutaneous procedures like tumor biopsy and celiac gangliolysis.
Implications:
- This integrated imaging strategy enhances the success of PTHBD.
- It offers a valuable, accessible alternative in resource-limited settings.
- The technique supports broader interventional radiology applications in developing nations.
