Hemobilia after percutaneous transhepatic biliary drainage
Archives of Surgery (Chicago, Ill. : 1960)
|February 1, 1980
Summary
Hemobilia, a rare complication of percutaneous transhepatic biliary drainage (PTBD), is often caused by intrahepatic vessel injury. Maintaining catheter patency is key for managing this condition.
Area of Science:
- Interventional Radiology
- Gastroenterology
- Hepatology
Background:
- Hemobilia is a known complication of percutaneous transhepatic biliary drainage (PTBD).
- Its incidence, causes, and management require further elucidation.
Purpose of the Study:
- To investigate the incidence, pathogenesis, and management of hemobilia in patients undergoing PTBD.
- To identify risk factors and effective treatment strategies for hemobilia.
Main Methods:
- Retrospective analysis of 94 patients who underwent PTBD.
- Evaluation of hemobilia incidence, severity, and patient outcomes.
- Correlation with hemostatic and hepatic function.
- Angiographic assessment in 47 patients.
Main Results:
- A total of 13.8% of patients experienced hemobilia (7.4% transient, 6.4% severe).
- One patient (1.1%) with severe hemobilia died.
- Hemobilia showed no correlation with hemostatic or hepatic insufficiency.
- Angiographic abnormalities, primarily arterial changes, were observed in 19.1% of patients and were associated with hemobilia.
Conclusions:
- Hemobilia after PTBD occurs more frequently than previously suspected.
- Intrahepatic vessel injury is the likely cause, not hemorrhagic diathesis or hepatic insufficiency.
- Maintaining continuous patency of the drainage catheter is the primary management strategy.
