ERCP & Bile Duct Stone Removal in Chennai: Procedure & Cost

A stone trapped in the bile duct blocks bile from draining, and that blockage causes the jaundice, infection or pancreatitis that usually brings patients in. ERCP clears it without opening the abdomen. Dr. Babu Elangovan is an M.Ch surgical gastroenterologist experienced in therapeutic endoscopy and HPB surgery — which matters here, because the same clinician can plan both the endoscopic clearance and the gallbladder surgery that usually follows.

This page covers the ERCP procedure itself. For the wider service — pancreatitis, pancreatic cysts, bile-duct strictures and injuries — see the pancreatic and biliary care speciality page.

What ERCP is

Endoscopic retrograde cholangiopancreatography combines upper GI endoscopy with real-time X-ray to reach and treat the bile and pancreatic ducts. A flexible side-viewing duodenoscope passes through the mouth, oesophagus and stomach to the duodenum, where the bile duct drains. Because access is through the mouth, there are no abdominal incisions — which is why recovery is measured in days rather than weeks.

It is a treatment, not a scan. ERCP was once used to diagnose duct problems, but non-invasive imaging — MRCP and endoscopic ultrasound — now does that job with none of the procedural risk. Modern practice reserves ERCP for cases where something needs to be done: clearing a stone, opening a stricture, placing a stent, sealing a leak. Diagnostic endoscopy of the stomach and bowel is a different, lower-risk procedure, covered under GI endoscopy.

When it is needed

The main indication is choledocholithiasis — a stone that has migrated out of the gallbladder and lodged in the common bile duct. Because the duct is narrow, a stone there stops bile draining into the intestine, and bile backs up into the liver and bloodstream.

That backup causes the presentations that need treatment:

• Obstructive jaundice — yellow eyes and skin, dark urine, pale stools. The causes are set out in our guide to what causes jaundice in adults.
• Acute cholangitis — bacterial infection of stagnant bile behind the blockage. Fever and chills with jaundice is an emergency requiring urgent drainage.
• Gallstone pancreatitis — inflammation when a stone obstructs where the bile and pancreatic ducts join. The distinction between acute and chronic disease is covered in acute vs chronic pancreatitis explained.
• Strictures, bile leak, or problems after gallbladder surgery, where the duct needs stenting or repair.

How these stones form and what else can be done about them is covered in bile duct stones: symptoms, causes and treatment.

The procedure, step by step

ERCP is done in an endoscopy suite with fluoroscopy, under sedation or general anaesthesia given and monitored by an anaesthetist. You will be asked not to eat or drink for roughly 6 to 8 hours beforehand.

1. Access. The duodenoscope is passed to the duodenum and the ampulla of Vater — the small opening where the bile and pancreatic ducts drain — is identified.
2. Cannulation and cholangiogram. A fine catheter is guided into the bile duct and contrast is injected, so X-ray imaging shows the number, size and position of the stones.
3. Sphincterotomy. A small, precise cut is made in the sphincter muscle at the duct opening using diathermy, widening it enough to pass instruments.
4. Stone extraction. A retrieval balloon or wire basket sweeps the stones out of the duct into the intestine, from where they pass naturally. Large stones may first need breaking up (mechanical lithotripsy).
5. Stenting if needed. If the duct cannot be fully cleared in one session, a temporary plastic or metal stent keeps bile draining while a further session is planned.

Most procedures take under an hour, though complex clearances take longer.

ERCP and gallbladder surgery: the two-stage pathway

This is the part patients most often misunderstand, and it matters.

Stones do not usually form in the bile duct. They form in the gallbladder and migrate. So clearing the duct treats the emergency, not the source.

The standard pathway is therefore sequential:

• Stage 1 — ERCP. Clear the duct, relieving the jaundice, infection or pancreatitis.
• Stage 2 — laparoscopic cholecystectomy. Once you have recovered and liver function has settled, the gallbladder is removed, usually within a few weeks.

Both halves matter. Operating on the gallbladder while a stone still obstructs the duct risks continued obstruction; clearing the duct and leaving the gallbladder leaves the source of future stones in place. The operation itself is covered in the gallbladder stone surgery guide, and whether every gallstone needs surgery is discussed in do all gallstones need surgery.

Risks, honestly

ERCP is effective, but it carries more risk than a routine diagnostic endoscopy. That is precisely why it is no longer used just to look.

Post-ERCP pancreatitis is the most important complication — inflammation of the pancreas from irritation or contrast near the pancreatic duct. It is the reason you are observed afterwards rather than sent straight home in every case. Risk varies with your anatomy, why the procedure is being done and how difficult cannulation proves, so it is a conversation to have about your own case rather than a single number.

Also recognised, and less common:

• Bleeding at the sphincterotomy site, usually controllable endoscopically during the same procedure.
• Infection (cholangitis) if the duct is not fully drained.
• Perforation — a rare tear of the duodenum or duct, which may need surgical repair.

Being treated by a unit that performs both therapeutic endoscopy and biliary surgery means that if a complication does occur, the team that manages it already knows your case.

Recovery

You are monitored in recovery until sedation wears off. ERCP is often day-care, though an overnight stay is common after a complex clearance or where pancreatitis risk warrants observation.

Eating restarts gradually — clear fluids once your swallow reflex has returned, then soft food, then a normal low-fat diet over the following days. Mild throat soreness and some bloating are expected and settle within a day.

Seek urgent review if you develop: severe or worsening abdominal pain radiating to the back, persistent vomiting, fever or chills, black tarry stools or vomiting blood, or deepening jaundice.

Cost in Chennai

Cost depends on what the procedure actually involves, so a written estimate follows assessment. Published ranges for therapeutic ERCP in Chennai fall broadly around INR 50,000 to INR 1,20,000, and the variables are:

• Therapeutic complexity — a straightforward single-session clearance versus one needing lithotripsy for large stones.
• Stenting — whether a stent is required, and whether plastic or self-expanding metal.
• Stone burden — and therefore whether more than one session is needed.
• Anaesthesia — sedation versus general anaesthesia with monitoring.
• Consumables — sphincterotomes, guidewires, balloons and baskets used.
• Day-care versus inpatient stay, and room category.

Insurance. Therapeutic ERCP for biliary obstruction is medically necessary and widely covered by private health insurance and corporate policies; the team coordinates pre-authorisation for cashless treatment. Eligible patients may be covered under the Tamil Nadu Chief Minister's Comprehensive Health Insurance Scheme (CMCHIS) at empanelled hospitals — confirm eligibility before admission.

Consult Dr. Babu Elangovan

Dr. Babu Elangovan is a surgical gastroenterologist with M.Ch super-specialty training and over 20 years of experience, practising both therapeutic GI endoscopy and HPB surgery. For biliary stone disease that combination is the point: the endoscopic clearance and the gallbladder operation are planned together rather than handed between teams.

Send your ultrasound, MRCP or LFT reports through the booking form or WhatsApp; Dr. Babu reviews them, usually the same day, and the team confirms a slot.

This page is general information, not medical advice. Whether ERCP is appropriate for you is decided only after individual clinical assessment by a qualified specialist, and outcomes vary between patients. If you have fever with jaundice, go to an emergency department now — an infected obstructed bile duct needs urgent drainage.
