Percutaneous Management of Benign Biliary Strictures

Area of Science:

• Gastroenterology
• Interventional Radiology
• Biliary Medicine

Background:

• Benign biliary strictures stem from diverse causes, frequently iatrogenic.
• Clinical signs range from asymptomatic elevations in liver enzymes to obstructive jaundice and recurrent cholangitis.
• Accurate diagnosis relies on imaging like ultrasound, CT, and MRCP to pinpoint stricture details and obstruction source.

Purpose of the Study:

• To review benign biliary strictures.
• To highlight percutaneous management strategies for biliary strictures.
• To provide an overview for interventional radiologists.

Main Methods:

• Review of diagnostic imaging modalities (ultrasound, MDCT, MRCP).
• Discussion of multidisciplinary management approaches (endoscopic, percutaneous, surgical).
• Focus on percutaneous transhepatic cholangiography for diagnosis and interventions.

Main Results:

• Percutaneous biliary interventions serve as a key diagnostic and therapeutic tool.
• Interventions include biliary drainage, balloon dilation, and stent placement (retrievable/biodegradable).
• Minimally invasive options are emphasized for patients unsuitable for endoscopic evaluation.

Conclusions:

• Percutaneous approaches are crucial for diagnosing and managing benign biliary strictures.
• Interventional radiologists play a vital role in offering minimally invasive treatment options.
• A multidisciplinary approach ensures optimal patient outcomes for biliary obstruction.
