About

This observational study is conducted to determine how the duodenal layer thicknesses (mucosa, submucosa, and muscularis) vary with several factors in patients with and without type 2 diabetes.

Full description

Study Objectives

To assess duodenal layer (mucosa, submucosa and muscularis) thickness differences between patients with and without type 2 diabetes using endoscopic ultrasound (EUS) and optical coherence tomography (OCT). To assess duodenal layer thickness differences between patients with type 2 diabetes. To assess duodenal layer thickness differences as a function of measurement location along the length of the duodenum. To compare measurements obtained by endoscopic ultrasound, to those obtained by optical coherence tomography.
