[Changing trends in percutaneous and endoscopic bile duct drainage]
Radiologia Diagnostica
|January 1, 1989
Summary
This study analyzes 1,104 non-surgical biliary drainages, finding endoscopic retrograde biliary drainage (ERCD) and percutaneous transhepatic biliary drainage (PTCD) are complementary, with PTCD used for complex cases.
Area of Science:
- Interventional Radiology
- Gastroenterology
- Biliary Interventions
Context:
- Analysis of 1,104 non-surgical biliary drainages performed between 1983 and 1988.
- Observes trends in the frequency, indications, and success rates of ERCD and PTCD.
- Notes a decrease in the proportion of PTCD procedures over the study period.
Purpose:
- To evaluate the evolving roles and outcomes of ERCD and PTCD.
- To understand the indications for each procedure, particularly in complex biliary obstructions.
- To assess the complementary nature and combined use of these drainage techniques.
Summary:
- Total non-surgical biliary drainage procedures increased, while PTCD's share decreased to 28%.
- PTCD (90.9% success) is primarily indicated for hilar benign/malignant biliary obstructions where ERCD is not feasible (85.9% success).
- Both ERCD and PTCD are increasingly utilized for combined palliative biliary drainage.
Impact:
- Highlights the complementary roles of ERCD and PTCD in managing biliary obstructions.
- Provides insights into the selection criteria and success rates for non-surgical biliary drainage.
- Informs clinical practice regarding the use of these interventional techniques for palliation.
