Endoscopic retrograde cholangiopancreatography (ERCP) is a minimally invasive procedure that combines flexible endoscopy with fluoroscopic X-ray imaging to evaluate and treat diseases affecting the bile ducts, gallbladder, and pancreatic duct. It is performed by specialist gastroenterologists or hepatobiliary surgeons with advanced endoscopy training, using a side-viewing duodenoscope—a thin flexible tube with a camera and light source—passed orally through the oesophagus and stomach to the duodenum.

At the duodenum, the Ampulla of Vater (the opening shared by the bile duct and pancreatic duct) is identified, and a fine catheter is passed through the endoscope's working channel into the ductal system. Contrast dye is injected and the ductal anatomy is visualised under real-time fluoroscopy. Depending on findings, therapeutic interventions may be performed immediately—including sphincterotomy to open the sphincter, stone extraction, stricture dilation, stent placement, or tissue sampling.

ERCP is primarily used today as a therapeutic rather than purely diagnostic tool; non-invasive imaging modalities such as MRCP and endoscopic ultrasound (EUS) have replaced diagnostic ERCP for most indications. The procedure is performed under conscious sedation with careful monitoring of oxygen saturation, heart rate, and blood pressure. It typically takes 30–90 minutes, with patients spending 2–4 hours in recovery before discharge or overnight admission for monitoring.

ERCP diagnoses and treats choledocholithiasis (stones in the common bile duct), which can cause jaundice, cholangitis (bile duct infection), and gallstone pancreatitis. Endoscopic stone extraction successfully clears the bile duct in over 90% of cases. Biliary strictures caused by primary sclerosing cholangitis, chronic pancreatitis, post-operative scarring, or malignancy (cholangiocarcinoma, pancreatic cancer) are dilated and stented to restore bile flow.

ERCP is also used to investigate and treat pancreatic duct disorders including pancreatic ductal strictures in chronic pancreatitis, pancreatic duct stones, and pancreatic leaks. Ampullary adenomas causing biliary obstruction may be diagnosed and sampled. Bile leaks following laparoscopic cholecystectomy—the most common iatrogenic biliary complication—are effectively managed with biliary stenting, which reduces the pressure gradient across the leak site and facilitates healing. Sphincter of Oddi dysfunction causing recurrent pancreatitis or biliary pain is evaluated by manometry and treated with sphincterotomy.

Candidates for ERCP are patients with confirmed biliary or pancreatic pathology on cross-sectional imaging (ultrasound, CT) or MRCP, where endoscopic intervention is expected to provide clinical benefit. Ideal candidates have standard duodenal anatomy (no prior gastric or bariatric surgery), can tolerate sedation, and have a corrected coagulation profile. Urgent ERCP within 24 hours is indicated for acute cholangitis (fever, jaundice, right upper quadrant pain—Charcot's triad), which represents a biliary emergency with significant mortality without biliary decompression.

Contraindications include uncorrected coagulopathy, duodenal obstruction, recent acute pancreatitis without cholangitis, Roux-en-Y anatomy (requiring specialised balloon enteroscopy-assisted ERCP), and patient inability to cooperate with sedation. Patients with contrast allergies require pre-medication. Pregnant patients should be positioned to minimise foetal radiation exposure, and the procedure should be performed only when strongly indicated, ideally with MRCP to guide the endoscopist and minimise fluoroscopy time.

The fundamental ERCP technique involves selective cannulation of the common bile duct or pancreatic duct using a catheter or sphincterotome. Wire-guided cannulation over a hydrophilic guidewire is the preferred technique and reduces the risk of post-ERCP pancreatitis compared to free-hand injection. Biliary sphincterotomy—incision of the sphincter of Oddi—is performed in most therapeutic ERCP cases to facilitate stone extraction and stent passage.

For stone disease, balloon sweeping using a Fogarty-type balloon catheter clears stones up to 12 mm; a Dormia wire basket is used for larger stones. Mechanical lithotripsy crushes large stones within a reinforced wire basket before extraction. Biliary stents—plastic or self-expanding metal—are placed over a guidewire for stricture management. In failed conventional ERCP, alternative access includes endoscopic ultrasound-guided biliary drainage (EUS-BD), percutaneous transhepatic cholangiography (PTC), or surgical bypass. Pre-cutting sphincterotomy, where the ampullary tissue is cut to access the bile duct when standard cannulation fails, requires particular expertise and increases procedural risk. Shared decision-making between the patient and specialist ensures the chosen modality aligns with individual anatomy, comorbidities, risk tolerance, and personal goals. A formal consultation with a board-certified specialist, review of pre-treatment imaging or investigation results, and multidisciplinary team input for complex cases are standard practice before finalising the treatment plan.

ERCP has transformed the management of bile duct disease by offering a minimally invasive alternative to open surgery for the vast majority of patients. Bile duct stone clearance is achieved in over 90% of cases, with same-day or next-day resolution of jaundice and biliary pain. Patients with cholangitis treated with urgent ERCP have significantly lower mortality than those managed conservatively or with delayed drainage. Biliary stenting in malignant obstruction achieves successful drainage in 85–90% of cases, with relief of pruritus and jaundice within 24–72 hours.

Long-term outcomes are excellent for benign indications: after successful stone clearance and subsequent cholecystectomy, patients are essentially cured of gallstone-related biliary disease. Patients with malignant biliary obstruction from unresectable cancer derive meaningful palliation from endoscopic stenting, with reduced hospitalisation compared to surgical bypass. Technical success rates exceed 90% at experienced high-volume centres, and the procedure has a well-established safety profile with mortality under 0.5% overall.

Post-ERCP pancreatitis (PEP) is the most frequent serious complication, occurring in 3–5% of patients overall and up to 15% in high-risk groups. It ranges from mild (requiring IV hydration for 2–3 days) to severe necrotising pancreatitis (less than 1%). Rectal indomethacin administered immediately before or after ERCP and pancreatic duct stenting in high-risk patients are evidence-based prophylactic measures. Post-sphincterotomy bleeding occurs in 1–2%, is usually manageable endoscopically, and rarely requires blood transfusion or surgery.

Perforation of the duodenum or bile duct occurs in 0.1–0.6% and may require surgical repair. Post-ERCP cholangitis (1–3%) results from inadequate biliary drainage and is managed with antibiotics and repeat biliary decompression. Pancreatitis, bleeding, and perforation together account for the majority of ERCP-related hospital admissions. Radiation exposure from fluoroscopy is a minor concern and is minimised by experienced endoscopists using pulse fluoroscopy and appropriate lead shielding. Cardiorespiratory complications from sedation are managed by continuous monitoring and availability of resuscitation equipment.

Most patients undergoing elective ERCP are discharged the same day after 2–4 hours of recovery monitoring. Patients may experience mild throat soreness from the endoscope, bloating, and abdominal fullness for several hours. A light diet can be resumed 2–4 hours post-procedure if there are no symptoms of complications. Patients should not drive on the day of the procedure due to sedation effects.

Liver function tests and amylase/lipase levels are checked 4–6 hours post-procedure or the following morning to screen for biliary or pancreatic complications. After bile duct stone clearance, elective cholecystectomy is scheduled within 4–6 weeks. Biliary stent patients are reviewed in 6–12 weeks with repeat liver function tests and imaging to assess stent function. Any post-procedure fever, worsening abdominal pain, or jaundice should prompt immediate medical review as these may indicate cholangitis, pancreatitis, or perforation requiring urgent assessment.

ERCP in the United States costs USD 6,000–18,000 depending on complexity, including hospital, endoscopist, anaesthesia, and fluoroscopy fees. Therapeutic interventions such as sphincterotomy, stone extraction, and stenting add incrementally to this base cost. Insurance coverage is standard when there is a documented biliary or pancreatic indication. In the UK, private ERCP costs GBP 2,500–7,000 at private hospitals.

In India at leading gastroenterology centres, ERCP costs USD 500–2,000, representing savings of 80–85% compared to US prices. Thailand and Singapore offer ERCP at USD 1,500–4,500. Turkey and Eastern Europe provide comparable procedures at USD 1,000–3,000. Patients considering medical travel should select high-volume centres with interventional endoscopy fellowship-trained gastroenterologists and adequate post-procedure monitoring facilities. Patients are advised to obtain itemised cost estimates from multiple providers and verify insurance coverage or national health system entitlements before proceeding. Medical tourism at accredited hospitals in India, Thailand, Turkey, or Mexico can reduce total procedure costs by 50–80% compared to US or UK pricing, with internationally trained specialists and comparable clinical outcomes for elective procedures.

For bile duct stones, laparoscopic common bile duct exploration (LCBDE) performed simultaneously with cholecystectomy achieves stone clearance rates comparable to ERCP without a separate procedure, and is preferred in patients with surgically altered anatomy or failed ERCP. Percutaneous transhepatic cholangiography with drainage provides an external biliary access route when ERCP is not technically feasible.

For purely diagnostic purposes, MRCP and endoscopic ultrasound (EUS) have replaced ERCP as the first-line investigations for suspected biliary and pancreatic pathology, due to their superior safety profiles. EUS-guided biliary drainage is an emerging rescue option when conventional ERCP fails. For malignant biliary obstruction in surgical candidates, hepaticojejunostomy or choledochojejunostomy provides durable surgical bypass with longer patency than endoscopic stenting.
