Sedation Depth and EGJ Endoscopic Grading: A Randomized Controlled Trial

Brief Study Summary: This prospective randomized controlled trial evaluates the impact of procedural sedation depth on the American Foregut Society (AFS) endoscopic grading of esophagogastric junction (EGJ) integrity and its correlation with objective gastroesophageal reflux disease (GERD) severity. A total of 192 adult patients undergoing diagnostic upper endoscopy were randomly allocated across three active sedation arms (Mild, Moderate, and Deep Sedation). Using a dual assessment protocol, AFS grades were recorded before and after sedation to assess how suppressing neuromuscular reflex tone unmasks underlying structural EGJ incompetence, with results correlated against baseline validated GerdQ scores, Los Angeles esophagitis grades, and 24-hour ambulatory pH-impedance monitoring.
