A standard gastroscopy or colonoscopy gives you a clear view of the digestive tract lining — but there are two things it cannot reach: the pancreas and biliary system hidden outside the gut wall, and obstructions inside the bile or pancreatic ducts that need hands-on treatment. That is where two advanced endoscopy techniques come in — endoscopic ultrasound (EUS) and endoscopic retrograde cholangiopancreatography (ERCP). At China's leading endoscopy centers these procedures are routine, scheduled within days, and cost significantly less than in the West: EUS runs about 500–3,500 RMB (roughly US$70–490), and a single-session ERCP for stone removal about 8,000–15,000 RMB (roughly US$1,100–2,100).
This guide is for international patients and families considering EUS or ERCP in China. It explains what each procedure is, what conditions they suit, who performs them, what they cost, what the risks are, and how to arrange the trip.
When a standard endoscope cannot reach
Gastroscopes and colonoscopes are excellent surface viewers, but their optics stop at the lining. Some lesions sit inside or beyond the wall — submucosal tumors, pancreatic masses, stones inside the bile duct — and some problems cannot be solved by looking at all: instruments must travel through the natural openings into the bile and pancreatic ducts. That is the division of labor between EUS and ERCP:
| Procedure | In essence | Main role |
|---|---|---|
| Endoscopic ultrasound (EUS) | Endoscope plus ultrasound probe | Diagnosis and staging: sees through and beyond the wall; guides needle biopsy |
| ERCP | Endoscope plus X-ray fluoroscopy | Treatment: enters the bile and pancreatic ducts to remove stones, dilate strictures, place stents |
In short: EUS sees deeper, ERCP goes in and treats. The two are also often used in sequence — EUS first to assess, then ERCP if needed.
EUS: radar for the digestive tract
EUS mounts a miniature ultrasound probe on the tip of the endoscope. From inside the stomach or duodenum, pressed against the pancreas and bile duct, it shows layers and structures that neither a standard endoscope nor external ultrasound can resolve. Typical uses:
Characterizing pancreatic cystic or solid masses (distinguishing cysts from tumors)
Assessing the origin and size of submucosal lesions (such as GI stromal tumors)
Staging GI cancers: depth of invasion and nearby lymph nodes
Investigating bile duct dilation and biliary strictures
Evaluating pancreatic parenchymal disease such as chronic pancreatitis
If you have been told abroad that you "need further imaging" or "should have a biopsy," getting the EUS in China usually means a faster arrangement — most hospitals can schedule it within days to two weeks.
EUS-FNA: tissue without open surgery
One of EUS's biggest values is fine-needle aspiration (EUS-FNA): under ultrasound guidance, a thin needle samples the lesion, turning "imaging suspicion" into "pathological evidence." This matters especially for pancreatic masses — since open surgery is highly invasive, doctors usually want a clear pathology or a thorough functional workup before committing to an operation. Public data from Beijing hospitals put the average cost of EUS-FNA at about 3,000 RMB (roughly US$420) per case, markedly lower than other tissue-diagnosis routes. Whether a biopsy is necessary, and what its risks are, is a decision your doctor makes based on the lesion's location and your overall condition.
ERCP: a minimally invasive gateway to the bile and pancreatic ducts
ERCP sends instruments through the duodenal papilla into the bile and pancreatic ducts and, under X-ray guidance, performs a range of treatments — often described as "biliary-pancreatic surgery without the incision":
Common bile duct stone extraction (with mechanical lithotripsy, balloons, or baskets)
Dilation and stenting of malignant or benign biliary strictures (metal or plastic stents)
Drainage and decompression for cholangitis and obstructive jaundice
Management of pancreatic duct strictures and stones
For bile duct stones, ERCP usually avoids open or laparoscopic bile duct exploration; for patients whose cancer compresses the bile duct, a stent can relieve jaundice within days.
China's endoscopy centers: scale and experience
Advanced endoscopy depends heavily on operator experience, so choosing the right center matters more than anything. The Endoscopy Center of Zhongshan Hospital (Fudan University) was founded in 1993 and is among the largest and highest-volume endoscopy centers in the world; since its new facility opened fully in November 2024, it has more than 40 procedure rooms, two day-wards with 92 beds, and an annual capacity raised to 180,000 procedures. The center pioneered multiple minimally invasive endoscopic techniques in China and each year hosts physicians from Europe, the Americas, Africa and beyond for advanced training. Beyond Zhongshan, a number of national key specialty hospitals in Beijing, Shanghai, Wuhan, and Guangzhou routinely perform EUS and ERCP — compare them in our guide to top gastroenterology hospitals and endoscopy centers. Some private hospitals with international departments (such as Shanghai United Family Hospital) also offer endoscopic ultrasound, suited to patients who prefer a private-care setting.
Costs: reference ranges for 2026
The ranges below vary with city, hospital tier, and case complexity; always confirm with the hospital's quote:
| Item | Reference range (RMB) | Approx. USD |
|---|---|---|
| EUS examination (site- and depth-dependent) | approx. 500–3,500 RMB | US$70–490 |
| EUS-FNA needle biopsy | avg. approx. 3,000 RMB per case | approx. US$420 |
| ERCP bile duct stone removal (per session) | approx. 8,000–15,000 RMB | US$1,100–2,100 |
| ERCP with stents/consumables and hospitalization (total) | up to approx. 20,000 RMB | approx. US$2,800 |
For comparison, hospital bills for the same procedures in Europe or North America are typically in the thousands to tens of thousands of US dollars (varies by insurance and hospital; conservative estimate). Even with flights and accommodation included, most international patients' total spend for EUS or ERCP in China remains clearly below what they would pay out of pocket at home. Note: if biopsy results indicate malignancy requiring surgery or chemotherapy, those costs are separate — ask the hospital for an estimate in advance.
Risks and informed consent: post-ERCP pancreatitis, honestly stated
To be candid: the benefits and risks of advanced endoscopy are both higher than a standard gastroscopy. ERCP's best-known complication is post-ERCP pancreatitis (PEP): reported incidence runs about 2–15%, with 5–10% the most commonly cited figure, and the vast majority of cases are mild to moderate and resolve within days. Other risks to understand include bleeding, duodenal perforation, and biliary infection. Standard preventive measures — rectal NSAIDs, prophylactic pancreatic stents in high-risk cases, and aggressive intravenous hydration — are routine at China's large centers. EUS complication rates are considerably lower, and infection or bleeding from needle biopsy is uncommon. Before signing the consent form, it is worth asking point by point: what is the expected benefit for me? Am I in a high-risk group for complications? What is the management pathway if one occurs?
Preparation and recovery
The two procedures share some preparation and differ in others:
Fasting for 6–8 hours before the procedure is standard
If you take anticoagulants or antiplatelet drugs, adjust them in advance as instructed (possibly stopping for several days)
Tell the doctor about contrast allergy and any past anesthesia reactions
EUS is usually an outpatient or day procedure under sedation; a short observation and you can leave
ERCP generally requires admission: several hours to overnight of monitoring, and most hospitals keep patients 1–3 days to watch for abdominal pain, fever, or elevated amylase
If a nasal biliary drain or stent was placed, you will receive specific follow-up arrangements before discharge
The international patient pathway
For patients arriving with complete imaging, the process can be compressed like this:
Pre-trip teleconsultation: upload CT/MRI/ultrasound reports and prior endoscopy records; the doctor assesses the indication and provides a plan and quote
Confirm the trip: most centers can schedule within days to two weeks; eligible nationalities can use the 240-hour visa-free transit
On arrival: pre-procedure tests and anesthesia assessment
Undergo EUS or ERCP (EUS — leave same day or next day; ERCP — admitted for several days)
Discharge summary, imaging, and pathology (for FNA, usually a few working days) are provided in English or translated, so your doctor at home can continue treatment
If pathology indicates surgery or oncology follow-up, we can also help arrange referrals and second opinions.
FAQs
Will it hurt? Both procedures are done under anesthesia or deep sedation — see our painless endoscopy overview.
Can ERCP clear all stones in one session? In most cases yes; with multiple, large, or awkwardly positioned stones, staged sessions may be needed — that is normal, not a treatment failure.
When do biopsy results come back? EUS-FNA cytology/pathology usually takes a few working days; confirm with the hospital before booking your flight home.
Why is the price a range? It depends on whether a biopsy is taken, stent type, length of stay, and anesthesia; the hospital's quote will itemize the variables.
