Video Capsule Endoscopy for Investigation of Obscure Gastrointestinal Bleeding: Feasibility, Results, and Interobserver Agreement

Abstract

Capsule endoscopy allowed the whole small intestine to be explored in 89 % of patients, with good visualization of the mucosa, except distally. Interobserver agreement was better among the experienced endoscopists and was better for red-colored abnormalities (bleeding and angiodysplasia) than for ulcers and tumors.
