Yield and impact of emergency capsule enteroscopy in severe obscure-overt gastrointestinal bleeding.
Patients with obscure-overt gastrointestinal bleeding (OOGIB) are defined by overt hemorrhage and negative upper and lower endoscopy findings. At present, the place of emergency capsule enteroscopy in patients with severe OOGIB is unknown. The aim of this study was to assess the diagnostic yield and the impact of emergency capsule enteroscopy on further management in patients with severe OOGIB. ⋯ Emergency capsule enteroscopy identified bleeding lesions in 67 % of patients with severe OOGIB. Emergency capsule enteroscopy seems to be a promising diagnostic tool with a subsequent impact on clinical management in patients with severe OOGIB.

Probe-based confocal laser endomicroscopy (pCLE) is a new imaging modality that enables histological examination of gastrointestinal mucosa during endoscopic procedures. Most studies have evaluated offline interpretation of pCLE images. In clinical practice, real-time interpretation is necessary to assist decision-making during the procedure. The aim of this pilot study was to compare the accuracy of real-time pCLE diagnosis made during the procedure with that of blinded offline interpretation to provide accuracy estimates that will aid the planning of future studies. ⋯ These results suggest that real-time and offline interpretations of pCLE images are moderately accurate. Real-time interpretation is slightly less accurate than offline diagnosis, but overall both are comparable. Additionally, there was contrasting accuracy between the two methods for small and large polyps.
