Research Description

Dr. Wang's research includes investigating the clinical effectiveness and safety of endoscopic techniques and technologies in the management of gastrointestinal diseases.

Current clinical areas of interest and investigation include: 1) advanced optical imaging endoscopy (narrow-band imaging) in the detection and diagnosis of GI neoplasia, including early GI cancers, 2) endoscopic mucosal resection (EMR) and endoscopic submucosal dissection (ESD) for the treatment of dysplasia and early GI malignancies, 3) use of photodynamic therapy (PDT) and radiofrequency ablation (RFA) for the treatment of inoperable pancreas and bile duct cancers, 4) advanced techniques and technologies in the endoscopic treatment of pancreatico-biliary disease via ERCP and EUS, 5) new techniques and technologies in GI endoscopy.
