Summary
Percutaneous transhepatic biliary drainage (PTHBD) effectively treated biliary obstruction in 93.5% of patients. While complications were minimal, late cholangitis occurred, requiring careful post-procedure catheter management.
Area of Science:
- Radiology
- Gastroenterology
- Interventional Radiology
Background:
- Biliary obstruction is a significant clinical challenge requiring effective management.
- Percutaneous transhepatic biliary drainage (PTHBD) has emerged as a less invasive alternative to surgical interventions.
Purpose of the Study:
- To evaluate the efficacy and safety of percutaneous transhepatic biliary drainage (PTHBD) in patients with biliary obstruction.
- To assess the overall success rate, complication profile, and postprocedural management requirements of PTHBD.
Main Methods:
- A consecutive series of 62 patients undergoing percutaneous transhepatic biliary drainage (PTHBD) were analyzed.
- Success was defined by achieving internal or external biliary drainage.
- Complications, bilirubin levels, and episodes of cholangitis were recorded and analyzed.
Main Results:
- An overall success rate of 93.5% (58/62) was achieved with PTHBD.
- Internal drainage was successful in 71.4% and external drainage in 19.3% of patients.
- Postprocedural complications were infrequent (3 patients), with no mortality. Late cholangitis occurred in 14.5% of cases.
Conclusions:
- Percutaneous transhepatic biliary drainage (PTHBD) is an effective radiological method for managing biliary obstruction.
- Careful postprocedural management is essential to address potential complications such as sepsis and catheter issues.
- PTHBD presents a viable alternative to surgical treatment for biliary obstruction.
