Percutaneous transhepatic cholangiography (PTC) is a medical procedure that is used to diagnose and treat problems in the bile ducts. PTC involves the insertion of a thin, flexible tube called a catheter through the skin and into the liver to inject a contrast dye into the bile ducts.
PTC can be used to diagnose and treat a variety of conditions, including:
- Bile duct strictures: PTC can be used to widen narrowed areas in the bile ducts caused by scar tissue or inflammation.
- Bile duct blockages: PTC can be used to remove blockages in the bile ducts caused by gallstones, tumors, or other obstructions.
- Bile duct leaks: PTC can be used to identify and treat leaks in the bile ducts.
Procedure:
PTC is typically performed on an outpatient basis under local anesthesia. The procedure takes about 30 to 60 minutes to complete and involves the following steps:
- Anesthesia: The patient is given a local anesthetic to numb the area where the catheter will be inserted.
- Catheter insertion: A small incision is made in the skin and a needle is inserted through the liver and into the bile ducts. A wire is passed through the needle, and a catheter is threaded over the wire and into the bile ducts.
- Dye injection: A contrast dye is injected into the bile ducts, which helps to make them visible on X-ray.
- Imaging: X-rays are taken to visualize the bile ducts and identify any problems, such as strictures or blockages.
- Treatment: If a problem is identified, it can often be treated during the same procedure. For example, if a blockage is identified, it can be removed using a small balloon catheter or stent.
Risks:
As with any medical procedure, PTC carries some risks, including:
- Bleeding: PTC can cause bleeding in the liver or bile ducts, which may require further treatment.
- Infection: PTC can increase the risk of infection, particularly in people with underlying health conditions.
- Perforation: PTC can cause a perforation or tear in the bile ducts or liver, which may require surgery to repair.
After the Procedure:
After the PTC procedure, the patient will be monitored in a recovery area until the sedative wears off. Patients may experience some discomfort, such as bloating or cramping, for a few hours after the procedure. Most patients can resume their normal activities within a day or two.
Percutaneous transhepatic cholangiography (PTC) is a medical procedure used to diagnose and treat problems in the bile ducts. PTC involves the insertion of a catheter through the skin and into the liver to inject a contrast dye into the bile ducts. PTC can be used to diagnose and treat a variety of conditions, including bile duct strictures, bile duct blockages, and bile duct leaks. PTC is generally a safe and effective procedure, but it does carry some risks. If you have any concerns about PTC or any other medical procedures, it is important to talk to your healthcare provider.
