Hemorrhage

This guideline covers diagnosing and managing atrial fibrillation in adults. It aims to ensure that people receive the best management to help prevent harmful complications, in particular stroke and bleeding.  

Sorry, I kinda feel like I turned two pages at once, and at the risk of asking a blindingly dumb question...Is there anywhere in the world where it is actually standard practice to do NGT lavage as a diagnostic tool in patients presenting with upper GI haemorrhage?
