Comparison of the Jcerity endoscoper airway and the endotracheal tube in endoscopic esophageal variceal ligation: a prospective randomized controlled trial

Abstract

AbstractVarious airway techniques have been used in endoscopic esophageal variceal ligation (EVL). In this respect, Jcerity endoscoper airway (JEA) is a novel laryngeal mask airway that is designed for use in gastrointestinal endoscopy. In the present study, 164 patients who underwent EVL were randomly divided into JEA group or endotracheal tube (ETT) group (ratio: 1:1). Success rate of endoscopic procedure, endoscope insertion time, procedure duration, recovery time, airway technique extubation time, anesthesia costs, hospital stay duration, complications, and hemodynamic parameters were recorded. The success rate of EVL in the JEA group was noninferior to that in the ETT group (98.8% vs. 100.0%). The airway insertion time, anesthesia duration, and recovery time were significantly shorter in the JEA group than in the ETT group (p < 0.001). Furthermore, the blood pressure during extubation was more stable in the JEA group (p < 0.001). Moreover, there were less heart rate variations during intubation (p < 0.005) and extubation (p < 0.05) in the JEA group. Nonetheless, the endoscopists’ satisfaction scores were comparable between the two groups. Overall, our findings suggest that JEA is efficient and safe for clinical use in EVL.Trial registration: Chinese Clinical Trial Registry, ChiCTR2000031892, Registered April 13, 2020, https://www.chictr.org.cn/searchproj.html.
