Philosophy of Care
Focused on patient-centered clinical care and researching application of technology for developing best care for gastrointestinal diseases in the patient.
Dr. Shiro Urayama specializes in advanced endoscopy including EUS (Endoscopic Ultrasound), ERCP (Endoscopic Retrograde Cholangiopancreatography) and various intra- and extra-luminal interventions including endoscopic mucosal resections/submucosal dissections, ablative procedures, and placement of luminal prosthesis for luminal and periluminal diseases.
He has published studies on the endoscopic approacheds in GI cancers and investigations on novel detection modalities of precancerous lesions. Specifically his research involves the application of endoscopic ultrasound, tumor markers for early diagnosis of pancreatic cancers, and the applications of optical technologies in early detections of dysplasia and cancer in esophagus.
Diagnostics and endotherapeutics for gastrointestinal malignancies specifically in upper GI tract and pancreaticobiliary organ. Translational research in pancreatic and esophageal cancer for development of early detection biomarkers.
