Core Tip	Disturbances in esophagogastric junction (EGJ) relaxation have previously been described in extreme older age (> 80 years). The functional consequences of such observations are not known. We investigated several novel metrics of EGJ function - EGJ-contractile integral (EGJ-CI), “total” EGJ-CI during swallowing and EGJ bolus flow time - in young controls and asymptomatic healthy older volunteers (> 80 years). Our findings indicate reduced swallow-induced EGJ relaxation and decreased EGJ bolus flow in older subjects. These findings confirm functional consequences for observations such as increased IRP measurements in older subjects and that caution applies when interpreting EGJ metrics in older patients.
