Digestive Endoscopy at Changhai Hospital Shanghai | CMCS

China's National Leader in Digestive Endoscopy

The Digestive Endoscopy Center at Changhai Hospital — affiliated with Naval Medical University (Second Military Medical University) — is widely recognized as China's premier digestive endoscopy center, with a national and international reputation for excellence in endoscopic submucosal dissection (ESD), endoscopic retrograde cholangiopancreatography (ERCP), endoscopic ultrasound (EUS), per-oral endoscopic myotomy (POEM), and the full spectrum of advanced therapeutic endoscopy. Performing among the highest volumes of advanced endoscopic procedures in China, Changhai Hospital's endoscopy center has trained generations of endoscopists across China and Asia, and its faculty have made landmark contributions to endoscopic technique and technology that have shaped the field nationally and internationally.

For international patients requiring advanced endoscopic diagnosis or treatment — whether for early gastrointestinal cancer, biliary or pancreatic disease, achalasia, subepithelial tumors, or complex endoscopic procedures that have been declined or are unavailable elsewhere — Changhai Hospital's digestive endoscopy center represents the gold standard in China. China Medical Concierge Shanghai (CMCS) provides seamless end-to-end coordination for international patients throughout their endoscopic care journey at Changhai Hospital.
