Endoscopy

The practice of sedation, including monitoring practice for digestive endoscopy, continues to evolve throughout the world. In many countries, including Switzerland, there is a trend towards increased utilization of sedation during both routine and advanced endoscopic procedures. Sedation improves patient satisfaction with endoscopy and also improves the quality of the examination. ⋯ This development between these socioeconomically very similar Western industrialized countries, however, shows some unique and surprising differences. In Germany and Switzerland, propofol use has become increasingly widespread, in Switzerland even to the extent that during the last few years propofol has overtaken benzodiazepine sedation, with an absolute majority of Swiss gastroenterologists using it without the assistance of an anesthesiologist. In addition, the change in Switzerland reflects a successful generalization of nonanesthesiologist-administered propofol (NAAP) sedation from the hospital setting to private practice.

Propofol for colonoscopy is largely administered by anesthesiologists or anesthesiology nurses in the United States (US) and Europe. Endoscopist-directed administration of propofol (EDP) by nonanesthesiologists has recently been proposed, with potential savings of anesthetist reimbursement costs. We aimed to assess potential EDP-related benefit in a screening setting. ⋯ The absolute economic benefit of EDP implementation in a screening setting is probably substantial with 10-year savings of $3.2 billion in the US and €0.8 billion in France. The impact of an eventual EDP-related mortality on EDP cost - effectiveness seems marginal. The huge economic and medical resources entailed by anesthetist-assisted colonoscopy could be more efficiently invested in other clinical fields.

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.
