Philosophy of Care

Dr. Shiro Urayama is focused on patient-centered clinical care and researching application of technology for developing best care for gastrointestinal diseases in the patient.

Clinical Interests

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 diagnostic and therapeutic intervention approaches in GI cancers and investigations on novel detection modalities of precancerous lesions. Specifically his research involves the application of endoscopic ultrasound and early diagnosis of gastrointestinal cancers.

Research/Academic Interests

Dr. Urayama's research forcuses on diagnostics and endoscopic therapeutics for gastrointestinal malignancies in GI tract and pancreas. He has keen interest in incorporating developing technology and translational research for development of early cancer detection schemes and therapeutics.
