[Revision process and present task: evidence-based clinical practice guidelines for gastroesophageal reflux disease]
Abstract:
Japanese Society of Gastroenterology published evidence-based clinical practice guidelines for gastro-esophageal reflux disease (GERD) on 2009. Since five years have already passed, the revision of the guideline is now necessary. The revision of the guidelines has been done according to the GRADE system and 11 new clinical questions have been added. The published information concerning the diagnosis and treatment of GERD after 2008 has also been added to guidelines. The new image-intensifying endoscopy for the diagnosis of GERD and the description concerning the concept, epidemiology, and diagnosis of Barrett's esophagus has been intensively re-written. Since the information concerning newly developed acid inhibitor, potassium-competitive acid blocker(P-CAB), is not included in the present revision. Annual review will be necessary in near future to include the clinical value of P-CAB.
