Therapeutic endoscopic retrograde cholangiopancreatography (ERCP) is a specialised endoscopic procedure that combines upper gastrointestinal endoscopy with fluoroscopic X-ray imaging to diagnose and treat diseases of the bile ducts, gallbladder, and pancreatic duct. Unlike purely diagnostic ERCP—which has largely been replaced by magnetic resonance cholangiopancreatography (MRCP) and endoscopic ultrasound—therapeutic ERCP provides direct intervention in the biliary and pancreatic systems, avoiding more invasive open surgery in the majority of patients.

During the procedure, a flexible side-viewing duodenoscope is advanced through the mouth, oesophagus, stomach, and into the second part of the duodenum, where the major duodenal papilla (Ampulla of Vater) is identified. A thin catheter is inserted through the papilla into the common bile duct or pancreatic duct, and contrast dye is injected to visualise the ductal system under fluoroscopy. Therapeutic manoeuvres—including sphincterotomy, stone extraction, stricture dilation, and stent placement—are performed through the working channel of the endoscope using specialised accessories.

Therapeutic ERCP is performed by highly trained interventional endoscopists with significant expertise in the technique. The procedure requires intravenous sedation (midazolam, fentanyl, propofol) or general anaesthesia depending on patient complexity. Patients are positioned in the left lateral or prone position, and the procedure typically takes 30–90 minutes. Patients are monitored for 2–4 hours post-procedure before discharge home, or admitted for overnight observation if complications are anticipated or the patient has significant comorbidities.

Therapeutic ERCP is the treatment of choice for choledocholithiasis (bile duct stones), which cause obstructive jaundice, biliary colic, cholangitis, and gallstone pancreatitis. Endoscopic sphincterotomy followed by balloon or basket stone extraction removes the stones from the common bile duct with a success rate exceeding 90% for standard stones. Biliary strictures—whether benign (post-surgical, primary sclerosing cholangitis, chronic pancreatitis) or malignant (cholangiocarcinoma, pancreatic cancer, ampullary cancer)—are dilated and stented using plastic or self-expanding metal stents to restore bile flow and relieve jaundice.

Other indications include management of bile leaks following laparoscopic cholecystectomy (treated with biliary stenting to reduce the pressure gradient), sphincter of Oddi dysfunction, pancreatic duct strictures in chronic pancreatitis, and removal of pancreatic duct stones with or without extracorporeal shock wave lithotripsy (ESWL). ERCP-guided photodynamic therapy and radiofrequency ablation (RFA) are emerging endoscopic treatments for unresectable cholangiocarcinoma, providing palliation of biliary obstruction.

Therapeutic ERCP is indicated for patients with confirmed biliary or pancreatic duct pathology that is amenable to endoscopic intervention, as confirmed by imaging (ultrasound, CT, MRCP). Ideal candidates are those in whom the expected therapeutic benefit outweighs procedural risk—for example, a patient with choledocholithiasis and ascending cholangitis requiring urgent bile duct clearance, or a patient with malignant biliary obstruction requiring stenting for palliation. Patients must be able to tolerate sedation or general anaesthesia and should hold anticoagulants pre-procedure where safe to do so.

Contraindications include severe coagulopathy (INR >1.5 or platelets <50,000 uncorrected), Billroth II or Roux-en-Y anatomy (which complicates access—specialised enteroscopy-assisted ERCP or surgical bypass may be required), known duodenal obstruction precluding scope passage, and patient refusal or inability to consent. Patients with active pancreatitis are not routinely offered ERCP unless there is concurrent cholangitis; biliary ERCP within 24–48 hours is appropriate for gallstone pancreatitis with cholangitis. Previous gastrectomy or bariatric surgery significantly alters anatomy and requires specialised endoscopic approaches.

Endoscopic biliary sphincterotomy (EST)—incision of the sphincter of Oddi using a specialised papillotome—is the fundamental manoeuvre that provides access to the bile duct and facilitates stone extraction and stent placement. Stone removal employs a Fogarty balloon catheter or Dormia wire basket to sweep or capture stones from the bile duct. Large or impacted stones may require mechanical lithotripsy (crushing within a wire basket), intraductal lithotripsy using laser or electrohydraulic energy, or pre-treatment with ESWL.

Biliary stenting uses plastic (polyethylene) stents for benign conditions requiring temporary drainage, or self-expanding metal stents (covered or uncovered) for malignant obstruction, where longer patency is required. Nasobiliary drainage tubes provide temporary external bile drainage and are particularly useful when stent placement is technically difficult or when bile sampling is needed. Pancreatic duct interventions include pancreatic sphincterotomy, pancreatic duct stenting for strictures or leaks, and stone extraction. In cases with surgically altered anatomy, device-assisted ERCP using balloon enteroscopes allows access to the papilla in Roux-en-Y gastric bypass and bilioenteric anastomosis configurations. 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.

Therapeutic ERCP achieves complete bile duct stone clearance in over 90% of cases with standard stone size and anatomy. It avoids open or laparoscopic common bile duct exploration surgery in the vast majority of patients, providing a minimally invasive solution with faster recovery. Relief of biliary obstruction with stenting reduces jaundice, improves liver function, and alleviates pruritus within 24–72 hours. In cholangitis, urgent biliary decompression via ERCP has been shown to reduce mortality compared to delayed intervention.

For malignant biliary obstruction, self-expanding metal stents remain patent for a median of 6–12 months, providing effective palliation. Studies demonstrate that endoscopic stenting achieves similar rates of successful biliary drainage to surgical bypass in unresectable malignancy, with lower morbidity and shorter hospitalisation. Technical success rates of ERCP are 90–95% in expert centres; in difficult cases such as surgically altered anatomy, success rates of 75–85% are achieved with device-assisted techniques.

Post-ERCP pancreatitis (PEP) is the most common serious complication, occurring in approximately 3–5% of standard procedures and up to 15% in high-risk patients (young women, suspected sphincter of Oddi dysfunction, difficult cannulation). PEP ranges from mild (managed with IV fluids and analgesics) to severe (necrotising pancreatitis requiring ICU admission, occurring in less than 1% of cases). Pre-procedure rectal indomethacin and pancreatic duct stenting in high-risk cases significantly reduce PEP incidence.

Bleeding following sphincterotomy occurs in 1–2% of cases and is usually manageable endoscopically with injection, coagulation, or clipping. Perforation of the duodenum or bile duct is rare (0.1–0.5%) but can require surgical repair. Cholangitis (infection of the biliary system) occurs in 1–3%, particularly when drainage is incomplete, and is treated with antibiotics and repeat biliary decompression. Stent occlusion requiring elective stent exchange occurs predictably with plastic stents (median 3–4 months). Contrast dye reactions are rare with modern non-ionic contrast agents.

After therapeutic ERCP, patients are monitored for 2–6 hours in a recovery area for signs of complications including abdominal pain, fever, and bleeding. A light diet can be resumed 2–4 hours post-procedure if the patient is comfortable. Patients are advised to rest for 24 hours after the procedure and avoid driving on the day of sedation. Most patients return to normal activities within 1–2 days.

Follow-up depends on the indication. After bile duct stone clearance, cholecystectomy is scheduled within 4–6 weeks if the gallbladder is still in situ, to prevent recurrent stone formation. Stented patients require follow-up imaging and elective stent exchange every 3 months for plastic stents, or at first signs of stent dysfunction for metal stents. Liver function tests are monitored post-procedure to confirm improved biliary drainage. Patients with underlying malignancy require oncology follow-up with CT or MRCP to monitor disease progression and stent function.

In the United States, a therapeutic ERCP with sphincterotomy and stone extraction costs USD 8,000–18,000 including hospital, endoscopist, and anaesthesia fees. Biliary stenting procedures cost USD 6,000–15,000. These costs are generally covered by health insurance with appropriate diagnostic indication. In the United Kingdom under private healthcare, ERCP costs GBP 3,000–8,000 depending on complexity.

In India at JCI-accredited tertiary hospitals such as Apollo, Fortis, or Medanta, therapeutic ERCP costs USD 800–2,500, representing savings of 70–85% compared to US prices. Thailand and Singapore offer ERCP at USD 2,000–5,000 at leading gastroenterology centres. Turkey and Poland provide comparable procedures at USD 1,500–4,000. The technical quality and safety standards at high-volume Asian centres match those of Western tertiary centres, with equivalent success and complication rates reported in peer-reviewed literature.

For bile duct stones in patients where ERCP is technically not feasible or has failed, laparoscopic common bile duct exploration (LCBDE) performed at the time of cholecystectomy provides an effective surgical alternative with comparable stone clearance rates. Percutaneous transhepatic cholangiography (PTC) with biliary drainage provides an external drainage alternative for biliary obstruction when ERCP cannot be performed due to surgically altered anatomy or failed access. Endoscopic ultrasound-guided biliary drainage (EUS-BD) is an emerging alternative for failed ERCP, providing transgastric or transduodenal access to the biliary system.

For malignant biliary obstruction, surgical bypass (hepaticojejunostomy or choledochojejunostomy) provides definitive palliation in patients fit for surgery, with longer stent-free intervals but higher short-term morbidity. In resectable biliary or pancreatic cancers, surgical resection (Whipple procedure for pancreatic head malignancy) remains the only curative option. ERCP stenting serves as a bridge to surgery by relieving pre-operative jaundice in selected cases.
