Recently, the need for sedation in gastrointestinal endoscopy has been increasing. However, the National Health Insurance Drug Price list in Japan does not include any drug specifically used for the sedation. Although benzodiazepines are the main medication, their use in cases of gastrointestinal endoscopy has not been approved. ⋯ The present guidelines comprise 14 statements, five of which were judged to be valid on the highest evidence level and three on the second highest level. The guidelines are not intended to strongly recommend the use of sedation for gastrointestinal endoscopy, but rather to indicate the policy as to the choice of appropriate procedures when such sedation is deemed necessary. In clinical practice, the final decision as to the use of sedation should be made by physicians considering patient willingness and physical condition.

There are few data concerning emergency double-balloon enteroscopy (DBE) and its usefulness in the management of severe acute obscure gastrointestinal bleeding (OGIB). The aim of this retrospective study was to evaluate emergency DBE and capsule endoscopy (CE) in patients with overt OGIB, analyzing the feasibility of this combined approach. ⋯ Emergency DBE is feasible, safe and effective in acute OGIB and may avoid major surgery, diagnosing and successfully treating most patients. Combined approach with RT viewing by CE is especially useful to identify recurrent bleeding vascular lesions such as DL that may be easily misdiagnosed by non-emergency DBE.

Colonoscopy is the criterion standard for detecting colorectal adenomas and cancers. However, multiple studies have reported a significant percentage of adenomas are missed during standard, forward-viewing colonoscopy. Missed adenomas can lead to interval colorectal cancers. ⋯ Thus, there is mounting evidence supporting the need to reduce the adenoma 'miss rate' of standard forward-viewing colonoscopy by improving upon current colonoscope technology and its current visualization/optics limitations. Recently, there are a number of emerging technologies that may help revolutionize how colonoscopy is carried out and that will significantly reduce adenoma miss rates. These include the Third Eye® Retroscope® and Third Eye® Panoramic(TM) (Avantis Medical Systems, Sunnyvale, CA, USA); Fuse® Full Spectrum Endoscopy® colonoscopy platform (EndoChoice Inc., Alpharetta, GA, USA); Extra-Wide-Angle-View colonoscope (Olympus, Tokyo, Japan), and the NaviAid(TM) G-EYE(TM) balloon colonoscope (SMART Medical Systems Ltd, Ra'anana, Israel).

Review Meta Analysis
Dexmedetomidine versus midazolam for gastrointestinal endoscopy: a meta-analysis.
Patients who undergo gastrointestinal endoscopy often require sedatives such as midazolam and the more recently developed alpha-2 agonist, dexmedetomidine. To assess the efficacy and safety of dexmedetomidine sedation for gastrointestinal endoscopy, we conducted a systematic review and meta-analysis of randomized controlled trials comparing dexmedetomidine with midazolam. ⋯ This meta-analysis shows that dexmedetomidine is a safe and effective sedative agent for gastrointestinal endoscopy, especially endoscopic retrograde cholangiopancreatography and endoscopic submucosal dissection.
