Glossary Entry: Biliary Catheter

Overview

Definition: A medical device used to drain bile from the liver or gallbladder when the normal flow is obstructed.

Detailed Description

Types and Variations

Variations: Biliary catheters can vary in size, material, and design, depending on the specific medical scenario and patient needs.

Indications

Common Uses: Biliary catheters are commonly used in cases of biliary obstruction, such as in patients with gallstones or tumors blocking the bile ducts.

Insertion and Placement

Procedure: Biliary catheters are inserted under fluoroscopic guidance, typically using the Seldinger technique to navigate through the bile ducts and reach the desired location for drainage.

Clinical Considerations

Potential Complications

Risks: Potential complications of biliary catheter placement include infection, bleeding, bile leakage, and catheter dislodgement.

Care and Maintenance

Maintenance Requirements: Proper care and maintenance of the biliary catheter include regular flushing, monitoring for signs of infection, and ensuring secure placement to prevent complications.

Additional Information

Related Devices

Associated Terms: Related devices include biliary stents, endoscopic retrograde cholangiopancreatography (ERCP) catheters, and percutaneous transhepatic cholangiography (PTC) catheters.

Innovations and Advancements

Recent Developments: Advances in biliary catheter technology have led to the development of more flexible and durable catheters for improved patient comfort and safety.

Regulatory and Safety Notes

Regulations: Biliary catheters must comply with regulatory standards for medical devices to ensure their safety and efficacy in clinical practice.
