Professor Yang Aiming: Pancreatobiliary and Interventional Endoscopy Specialist
Professor Yang Aiming is director of the Department of Gastroenterology and its endoscopy training center at Peking Union Medical College Hospital. He is a senior physician, professor, doctoral supervisor, and a leading specialist in endoscopic ultrasound, ERCP, pancreatobiliary disease, early gastrointestinal cancer, and minimally invasive endoscopic treatment.
International patients can learn more about the hospital, multidisciplinary services, and consultation preparation in our Peking Union Medical College Hospital international patient guide.
Clinical and Academic Focus
- endoscopic ultrasound and EUS-guided biopsy;
- ERCP for bile-duct and pancreatic-duct disease;
- pancreatic cancer and pancreatic cysts;
- biliary stricture and cholangiocarcinoma;
- bile-duct stones and complex gallstone disease;
- chronic pancreatitis;
- early gastric and esophageal cancer;
- esophageal and gastric varices; and
- combined EUS and ERCP procedures.
Endoscopic Ultrasound
Endoscopic ultrasound, or EUS, combines endoscopy with high-resolution ultrasound. It can examine the pancreas, bile duct, gallbladder, digestive wall, lymph nodes, and nearby blood vessels from inside the gastrointestinal tract.
EUS-guided fine-needle biopsy can obtain tissue from pancreatic masses, lymph nodes, subepithelial lesions, and other targets. Sample quality, needle choice, pathology processing, and the question being asked all affect diagnostic yield.
ERCP
Endoscopic retrograde cholangiopancreatography, or ERCP, is mainly a treatment procedure for bile-duct and pancreatic-duct disorders. It can remove stones, drain an obstruction, place a stent, treat selected strictures, and manage some postoperative leaks.
Potential complications include pancreatitis, bleeding, infection, perforation, and sedation-related events. ERCP should be used when the expected diagnostic or therapeutic benefit justifies these risks.
Combined EUS and ERCP
Professor Yang has promoted an integrated “two-E” approach combining EUS and ERCP. EUS can clarify anatomy, identify a lesion, and obtain tissue, while ERCP can provide drainage or duct treatment.
Performing the procedures in a coordinated pathway may reduce delays for selected patients, but not everyone requires both tests or needs them during one session.
Biliary Strictures and Cholangiocarcinoma
A narrowed bile duct can result from cancer, inflammation, surgery, pancreatitis, autoimmune disease, or another benign condition. Symptoms may include jaundice, itching, fever, abdominal pain, pale stool, and dark urine.
Diagnosis can require CT, MRI with MRCP, EUS, ERCP sampling, cholangioscopy, blood tests, and pathology review. A negative brushing or biopsy does not always exclude cancer because bile-duct lesions can be difficult to sample.
Pancreatic Cancer and Pancreatic Lesions
Pancreatic masses and cysts require assessment of imaging features, symptoms, growth, duct involvement, tumor markers, and tissue when it will change management.
EUS can support staging and biopsy, while ERCP may relieve bile-duct obstruction in selected patients. Treatment planning should involve gastroenterology, pancreatic surgery, oncology, radiology, and pathology.
Chronic Pancreatitis
Chronic pancreatitis can cause recurrent pain, pancreatic-duct stones or narrowing, malabsorption, weight loss, and diabetes. Management can include lifestyle measures, enzyme replacement, pain treatment, endoscopic therapy, surgery, and nutrition support.
Repeated endoscopic procedures are not always the best long-term solution. Complex disease should be reviewed jointly by endoscopy and pancreatic surgery teams.
Early Gastrointestinal Cancer
Selected early cancers or precancerous lesions of the esophagus and stomach can be removed endoscopically through techniques such as endoscopic submucosal dissection. Suitability depends on depth, size, ulceration, pathology, and risk of lymph-node spread.
Final pathology determines whether endoscopic removal was curative or whether additional surgery should be considered.
Variceal Bleeding
Esophageal or gastric varices can cause life-threatening bleeding in patients with portal hypertension. Vomiting blood, black stool, fainting, or shock requires immediate local emergency treatment.
Endoscopic therapy may be combined with medication, radiological intervention, or liver-disease management depending on the source and severity.
Who May Consider a Consultation?
- patients with a pancreatic mass or indeterminate pancreatic cyst;
- patients with unexplained bile-duct narrowing or obstructive jaundice;
- patients needing EUS-guided biopsy or complex ERCP;
- patients with recurrent bile-duct stones;
- patients with chronic pancreatitis and duct obstruction;
- patients with suspected early gastric or esophageal cancer;
- patients with portal-hypertension-related varices; or
- patients seeking a second opinion after an inconclusive endoscopic procedure.
Medical Records to Prepare
- a concise symptom and treatment timeline;
- contrast-enhanced CT, MRI, MRCP, and PET-CT in original DICOM format;
- previous endoscopy, EUS, ERCP, and cholangioscopy reports with images;
- pathology reports, glass slides, and paraffin blocks;
- cytology, brushings, molecular, and tumor-marker results;
- operative and interventional-radiology records;
- liver, kidney, blood-count, coagulation, amylase, and lipase results;
- details of any biliary or pancreatic stents;
- a complete medication list, including anticoagulants; and
- a clear list of diagnostic and treatment questions.
Planning an International Consultation
Fever with jaundice, vomiting blood, black stool, severe abdominal pain, fainting, or shock requires immediate local hospital care.
Stable patients should confirm whether original imaging, pathology, and endoscopy data can be reviewed. Remote medical-record review requires physician authorization. Final procedure eligibility, preparation, and timing require complete specialist assessment.
How CMCS Can Assist
CMCS – China Medical Concierge Shanghai is an independent medical concierge and health management company, not a hospital. We assist international patients with organizing and translating gastroenterology records, identifying an appropriate specialist, requesting appointment availability, arranging interpretation, and planning medical travel in China.
Access to Professor Yang, remote review, EUS, ERCP, or a particular endoscopic treatment is subject to doctor and hospital approval. CMCS does not guarantee appointments, procedure eligibility, diagnosis, or clinical outcomes.
