When the bile duct becomes blocked, bile cannot flow from the liver into the intestine. It backs up into the blood, turning the skin and eyes yellow (jaundice), causing intense itching, dark urine and pale stools — and, if infection sets in, it can become dangerous quickly. Biliary drainage in Delhi — percutaneous transhepatic biliary drainage (PTBD) — relieves this blockage by placing a thin drainage tube into the bile ducts through the skin, under imaging guidance. At Edge Imaging & Diagnostics in Paschim Vihar, West Delhi, this minimally invasive, image-guided procedure is used to treat obstructive jaundice.
This guide explains what biliary drainage is, when it is needed, what it achieves, and what to expect from the procedure.

What Is Percutaneous Biliary Drainage (PTBD)?
Percutaneous transhepatic biliary drainage (PTBD) is an image-guided procedure in which a fine catheter is passed through the skin and liver into the blocked bile ducts to drain the trapped bile. Guided by ultrasound and X-ray (fluoroscopy), the radiologist reaches the bile ducts through a tiny puncture — no open surgery is needed. The bile can be drained externally into a bag, internally past the blockage, or a stent can be placed to keep the duct open.
Why and When Is Biliary Drainage Needed?
Biliary drainage is needed when something blocks the bile ducts and causes obstructive jaundice. Common causes include:
- Tumours — cancer of the pancreas, bile duct (cholangiocarcinoma), gallbladder, or lymph nodes pressing on the duct
- Bile duct strictures (narrowing), sometimes after surgery
- Bile duct stones blocking the flow
- Cholangitis — an infected, blocked bile system, which is a medical emergency
Draining the bile relieves the jaundice and itching, protects the liver, and treats or prevents infection.
What Biliary Drainage Achieves
Beyond relieving distressing symptoms, PTBD serves several important purposes: it lowers dangerously high bilirubin levels and improves liver function, controls or prevents life-threatening infection (cholangitis), and prepares a patient for further treatment — such as surgery, chemotherapy or the placement of a permanent stent. In advanced cancers, it provides valuable palliation, greatly improving comfort and quality of life.
External Drainage, Internal Drainage or Stent?
Depending on the blockage, the radiologist chooses the best option: an external drain collects bile into a bag outside the body; an internal-external drain also allows bile to pass into the intestine; and in suitable cases a stent (a small tube left inside the duct) holds it open with no external bag. The choice depends on the cause, location and your overall treatment plan.
Why Image Guidance Makes It Safe
The bile ducts are deep within the liver and close to major blood vessels. Ultrasound and fluoroscopic guidance let the radiologist see the ducts and needle in real time, choosing the safest path and confirming correct placement. This precision is what makes PTBD both effective and low-risk. At Edge, it is performed as part of our interventional radiology services, supported by high-resolution ultrasound and CT such as a CECT abdomen to map the blockage beforehand.
How the Procedure Works
PTBD usually takes around 30–60 minutes:
- Imaging & planning: the level and cause of the blockage are assessed on ultrasound/CT.
- Cleaning & anaesthesia: the skin over the right upper abdomen is cleaned and numbed; sedation is usually given.
- Needle access: under live imaging, a fine needle is guided into a bile duct and contrast is used to map the ducts.
- Catheter placement: a guidewire is passed across or up to the blockage, and a drainage catheter (or stent) is positioned.
- Drainage: bile begins to drain; the catheter is secured to the skin and, if external, connected to a bag.
After the Procedure & Tube Care
Many patients notice the itching and unwell feeling ease within a few days as bilirubin falls. If you have an external or internal-external drain, simple care keeps it working: keep the tube and dressing clean and dry, do not pull on it, and watch for fever, leakage or reduced drainage. The tube is flushed and changed periodically, and your treating team plans the next steps — stenting, surgery or oncology treatment — depending on the underlying cause.
Is Biliary Drainage Painful or Risky?
The procedure is done under local anaesthesia with sedation, so most patients feel only pressure. Some soreness at the tube site afterwards is normal and easily managed. PTBD is a well-established, safe procedure; uncommon risks such as bleeding, bile leak or infection are minimised by image guidance and careful technique. For an infected, blocked bile system, the relief it provides can be life-saving.

Frequently Asked Questions
How soon does jaundice improve after biliary drainage?
Symptoms like itching often ease within a few days as bilirubin levels fall. The visible yellowing fades more gradually over one to two weeks, depending on how high the levels were.
Is the biliary drainage procedure painful?
It is done under local anaesthesia with sedation, so most people feel only pressure. Mild soreness afterwards is easily managed with simple pain relief.
Will I have to live with an external bag?
Not always. Depending on the blockage, an internal-external drain or a stent may avoid a permanent external bag. Your radiologist chooses the best option for your case.
How long does the drain stay in?
It varies with the underlying cause. It may be temporary — until surgery or stenting — or longer-term for palliation. The tube is changed periodically while in place.
Is biliary drainage a cure?
PTBD treats the blockage and its symptoms, but the underlying cause (such as a tumour or stricture) still needs its own treatment. It is often an important step that makes further treatment possible.
How much does biliary drainage (PTBD) cost in Delhi?
The cost depends on the procedure and whether a stent is placed. Edge Imaging offers transparent pricing — call 9555999960 for an estimate. PTBD is often covered by health insurance as a medically necessary procedure.
Where can I get biliary drainage in West Delhi?
Edge Imaging & Diagnostics in Paschim Vihar offers image-guided biliary drainage, serving Raghubir Nagar, Moti Nagar, Rajouri Garden and nearby areas. Call 9555999960 for prompt help with obstructive jaundice.
What is the difference between PTBD and a biliary stent?
PTBD drains bile using a catheter (external, internal-external, or internal), while a stent is a small tube left inside the duct to hold it open with no external bag. Often a drain is placed first and a stent later, depending on the cause.
