Capsule enteroscopy is useful for the therapeutic management of Crohn's disease.

Aim: To analyze therapeutic changes in Crohn's disease (CD) patients following video capsule endoscopy (VCE) and to assess the usefulness of Lewis score and the Patency Capsule.

Methods: Patency Capsule was performed in every patient that had indication for VCE, and those with negative patency did not undergo VCE. Patients with established CD that underwent VCE between January 2011 and February 2014 were selected for this study; those with suspected CD were excluded, independent of VCE results, since our purpose was to address differences in therapeutic regimen in CD patients before and after VCE.

Despite the high functional reserve of the pancreas, it is recognized that a significant proportion of diabetic patients may also have a deficit of the exocrine function. The aim of this study was to screen patients with diabetes mellitus (DM) for pancreatic exocrine insufficiency.
