Darin Lyn Dufault, MD

Assistant Professor of Medicine
Email address darin.dufault@duke.edu

My work is focused on the management of complex lesions of the GI tract, including advanced adenomas, dysplasia, and early cancers.  This is done through the use of advanced luminal endoscopic techniques such as endoscopic submucosal dissection, mucosal resection, and endoscopic suturing.  Additionally, I treat motility disorders of the esophagus and stomach through the use of per oral endoscopic myotomy, as well as gastroesophageal reflux with transoral incisionless fundoplication. 

My research interest focuses mainly in the development of novel devices and technology to make endoscopic procedures safer and more effective for patients.  

Lastly, I am the Director of the Gastroenterology Clinical Clerkship for the School of Medicine.
