Endoscopic meatus scoring scale versus sniff test to predict insertability before transnasal endoscopy: A prospective, randomized study.

Background And Aim: Sniff test is a common method before unsedated transnasal esophago-gastro-duodenoscopy (UT-EGD) to select a nostril insertion site. Yet there is no objective method to select a more specific meatus insertion tract for anesthesia and insertion. We devised an endoscopic meatus scoring scale by anterior meatuscopy to select the most optimal meatus insertion tract.

Levofloxacin-amoxicillin/clavulanate-rabeprazole versus a standard seven-day triple therapy for eradication of Helicobacter pylori infection.

The resistance rates of Helicobacter pylori to amoxicillin and metronidazole therapy are higher in eastern Taiwan as compared to national and worldwide rates. The high resistance rate in this territory justified a search for a better eradication regimen. We conducted an open-labeled, prospective, randomized, and controlled study in a tertiary referral hospital in eastern Taiwan.
