With comprehensive specialty training, Dr. Otaki provides care for patients with a myriad of gastrointestinal symptoms and disease. His clinical interest and research projects are focused on the care of patients with a variety of esophageal diseases.  This has included Barrett’s esophagus, esophageal cancer, eosinophilic esophagitis, gastroesophageal reflux, achalasia and other esophageal motility abnormalities. 

He also performs several specialized procedures in his subspecialty: endoscopic mucosal resection, esophageal dilation, ablative therapies of the foregut (radiofrequency ablation, spray cryotherapy, balloon cryotherapy, argon plasma coagulation), reflux testing (including wireless testing), and high resolution esophageal manometry.

His training includes the use of novel diagnostic tools (confocal laser endomicroscopy, optical coherence tomography, impedance planimetry), and minimally invasive diagnostic tools (transnasal endoscopy, cytosponge).

Dr. Otaki’s ongoing research activities include the role of endoscopic therapy in the management of early esophageal cancer, systemic side effects of steroid based therapy in allergy mediated esophageal diseases, and optimal ablation strategies in the care of dysplastic Barrett’s esophagus.
