Impact of a computer-based teaching module on characterization of diminutive colon polyps by using narrow-band imaging by non-experts in academic and community practice: a video-based study.

Background: Experts can accurately characterize the histology of diminutive polyps with narrow-band imaging (NBI). There are limited data on the performance of non-experts.

Objective: To assess the impact of a computer-based teaching module on the accuracy of predicting polyp histology with NBI by non-experts (in academics and community practice) by using video clips.

Defining patients at high risk for gastrointestinal hemorrhage after drug-eluting stent placement: a cost utility analysis.

Introduction: The study goal was to evaluate the cost-effectiveness of drug-eluting stent (DES) placement with consideration of gastrointestinal (GI) bleeding risk. DES reduce the need for future coronary revascularization, but require prolonged dual anti-platelet (DAT) therapy, which may increase the risk for GI bleeding. While DES have been found to be cost-effective in patients at average risk for GI bleeding, they may not be the most cost-effective strategy in higher risk patients.

The usefulness of routine small bowel biopsies in evaluation of iron deficiency anemia.

Background: Iron deficiency anemia (IDA) may be the sole manifestation of celiac disease. The role of routine small bowel biopsies obtained during endoscopy in the evaluation of IDA is unclear. This study assessed the usefulness of routine small bowel biopsies in patients presenting with IDA.

The insensitivity of endoscopic markers in celiac disease.

Objectives: Celiac disease (CD) is characterized by small intestinal inflammation and mucosal atrophy. Endoscopic markers of villous atrophy are reported to be present in 88-100% of untreated celiac patients. In patients being evaluated for iron deficiency anemia (IDA), we examined whether endoscopic markers could predict histological results consistent with CD.
