About Dr. Xu Guoming
Dr. Xu Guoming (许国铭) is a Professor, Doctoral Supervisor, and one of China's most experienced and technically accomplished endoscopists in the field of endoscopic retrograde cholangiopancreatography (ERCP) and pancreatobiliary endoscopy, based at the Department of Gastroenterology, Changhai Hospital, Naval Medical University (Second Military Medical University). Working within one of China's highest-volume and most technically advanced digestive endoscopy programs — the department built by Academician Li Zhaoshen into a national center of excellence for therapeutic endoscopy and pancreatic disease — Dr. Xu has accumulated an exceptional case volume in ERCP and related pancreatobiliary endoscopic interventions, and is recognized as a leading authority on the endoscopic management of biliary and pancreatic diseases including choledocholithiasis, biliary strictures, pancreatic duct stones, chronic pancreatitis, and biliary and pancreatic malignancies.
ERCP — endoscopic retrograde cholangiopancreatography — is the cornerstone interventional technique for the diagnosis and treatment of diseases of the bile ducts and pancreatic duct. In expert hands, ERCP enables the removal of bile duct stones, the relief of biliary obstruction caused by strictures or tumors, the drainage of the pancreatic duct in chronic pancreatitis, and the tissue sampling of biliary and pancreatic lesions — all without surgery, through a flexible endoscope passed through the mouth. The safety and efficacy of ERCP are highly dependent on operator experience and case volume: at high-volume centers with experienced endoscopists, ERCP achieves high success rates with low complication rates; at lower-volume centers, complication rates — including post-ERCP pancreatitis, bleeding, and perforation — are substantially higher. Dr. Xu's case volume and technical expertise place him among China's elite ERCP endoscopists, and Changhai Hospital's pancreatobiliary endoscopy program is one of the most active and experienced in the country.
For international patients with biliary or pancreatic disease requiring endoscopic intervention — whether bile duct stones, biliary strictures, pancreatic duct stones, or biliary obstruction from malignancy — Dr. Xu and Changhai Hospital's ERCP program offer a combination of technical expertise, case volume, and institutional infrastructure that is available at only a small number of centers in China.
Hospital Affiliation: Department of Gastroenterology, Changhai Hospital
Changhai Hospital (长海医院), affiliated with Naval Medical University, is one of Shanghai's largest and most prestigious academic medical centers and a national leader in gastroenterology, digestive endoscopy, and pancreatic disease. Its Department of Gastroenterology performs one of the highest volumes of ERCP procedures in China annually, supported by a dedicated pancreatobiliary endoscopy suite equipped with the latest generation of duodenoscopes, cholangioscopes (SpyGlass digital single-operator cholangioscopy), and fluoroscopic imaging systems. The department's ERCP program is supported by a multidisciplinary pancreatobiliary team comprising gastroenterologists, hepatobiliary surgeons, interventional radiologists, and oncologists, enabling seamless integration of endoscopic, surgical, and radiological approaches to complex biliary and pancreatic disease.
The department's endoscopic ultrasound (EUS) program — closely integrated with the ERCP service — provides high-resolution imaging and tissue sampling for pancreatic masses, biliary lesions, and subepithelial tumors, and EUS-guided biliary drainage as a rescue technique when ERCP fails or is not technically feasible. The combination of high-volume ERCP, advanced cholangioscopy, and EUS-guided intervention makes Changhai Hospital one of the most comprehensively equipped pancreatobiliary endoscopy centers in China.
Clinical Specialties: What Dr. Xu Guoming Treats
- Choledocholithiasis (bile duct stones) — endoscopic sphincterotomy and stone extraction for common bile duct stones; mechanical lithotripsy, electrohydraulic lithotripsy (EHL), and laser lithotripsy via SpyGlass cholangioscopy for large or impacted stones not amenable to standard extraction; management of Mirizzi syndrome and intrahepatic duct stones
- Biliary strictures — endoscopic diagnosis and management of benign biliary strictures (post-surgical, post-inflammatory, primary sclerosing cholangitis) and malignant biliary strictures (cholangiocarcinoma, pancreatic cancer, ampullary cancer, metastatic disease); endoscopic biliary stenting with plastic or self-expanding metal stents (SEMS); SpyGlass cholangioscopy with targeted biopsy for indeterminate strictures
- Malignant biliary obstruction — endoscopic biliary drainage for jaundice caused by pancreatic cancer, cholangiocarcinoma, ampullary cancer, and metastatic biliary obstruction; placement of covered and uncovered SEMS for palliative biliary drainage; pre-operative biliary drainage for resectable tumors; coordination with hepatobiliary surgery and oncology for multidisciplinary management
- Chronic pancreatitis and pancreatic duct stones — endoscopic pancreatic sphincterotomy and pancreatic duct stone extraction; extracorporeal shock wave lithotripsy (ESWL) coordination for large pancreatic duct stones prior to endoscopic extraction; pancreatic duct stenting for dominant strictures; management of pancreatic pseudocysts via endoscopic transmural drainage
- Ampullary and periampullary disease — endoscopic ampullectomy for ampullary adenomas; diagnosis and staging of ampullary carcinoma; endoscopic management of periampullary diverticula complicating ERCP

- SpyGlass single-operator cholangioscopy — direct visual inspection of the bile duct and pancreatic duct for indeterminate strictures, intraductal papillary mucinous neoplasms (IPMNs), and difficult stone management; targeted intraductal biopsy under direct vision; EHL and laser lithotripsy under cholangioscopic guidance
- EUS-guided biliary drainage — EUS-guided choledochoduodenostomy and hepaticogastrostomy as rescue biliary drainage techniques when standard ERCP fails due to altered anatomy, duodenal obstruction, or prior surgery; EUS-guided gallbladder drainage for acute cholecystitis in high-surgical-risk patients
Why International Patients Choose Dr. Xu Guoming and Changhai Hospital
International patients seek ERCP and pancreatobiliary endoscopy services from Dr. Xu Guoming and Changhai Hospital for reasons that reflect both the technical excellence of the program and the practical advantages of accessing specialist endoscopic care in Shanghai.
For patients with bile duct stones — particularly large, multiple, or impacted stones that have failed standard ERCP at lower-volume centers — Dr. Xu's expertise in advanced lithotripsy techniques including SpyGlass-guided EHL and laser lithotripsy provides access to stone clearance options that are not widely available outside major academic endoscopy centers. The ability to clear difficult bile duct stones endoscopically — avoiding the need for surgical bile duct exploration — is a significant clinical and practical advantage for international patients who wish to avoid major surgery.
For patients with biliary strictures of uncertain etiology — where the distinction between benign and malignant stricture has not been established by standard imaging and brush cytology — SpyGlass cholangioscopy with targeted intraductal biopsy at Changhai Hospital provides a diagnostic capability that frequently resolves the diagnostic uncertainty and enables appropriate treatment planning.
For patients with malignant biliary obstruction requiring endoscopic biliary drainage as part of their oncological management, Changhai Hospital's high-volume ERCP program and multidisciplinary pancreatobiliary team provide the technical expertise and institutional infrastructure to achieve reliable biliary drainage with low complication rates, and to integrate the endoscopic management seamlessly with the overall oncological treatment plan.
The cost of ERCP and pancreatobiliary endoscopy at Changhai Hospital is substantially below that of equivalent procedures in Western healthcare systems, and access to Dr. Xu's endoscopy schedule can typically be arranged within days through CMCS.
