Abstract

Background: Esophageal diverticula have been associated with esophageal motility disorders, most commonly achalasia. We aimed to evaluate high-resolution manometry (HRM) motility diagnoses and pressurization patterns in patients with esophageal diverticula. Methods: Patients were retrospectively identified for distal esophageal diverticula and previously completed HRM. High-resolution manometries were analyzed according to the Chicago Classification, and the pressure slope of the compartmentalization phase (time between upper esophageal sphincter closure and the transition zone) of esophageal bolus transit was measured. Pressure slopes were also measured in 10 asymptomatic volunteers (controls) for comparison. Key Results: Nineteen patients (ages 31-83) were included. Eight (42%) patients had normal motility, five (26%) had esophagogastric junction outflow obstruction, and two (11%) had jackhammer esophagus; four patients had other motility diagnoses including only one patient with achalasia. A total of six patients (32%) had at least one hypercontractile swallow. Greater compartmentalization phase pressure slopes were observed in patients at the mid-esophageal body in both supine (median [interquartile range]: 1.9 mmHg/s [0.9, 3.6]) and upright (1.1 [0.1, 3.1]) positions than in controls (supine: -1.3 [-2.4, -0.11], p = 0.001; upright; -0.71 [-2.1, -0.02], p = 0.005). Conclusions & Inferences: Propagating peristalsis, often with hypercontractility, was commonly seen in our cohort of patients with esophageal diverticula. Abnormal compartmentalization phase pressurization may indicate a relationship of abnormal esophageal wall mechanics and/or compliance with diverticula; however whether these findings are causal or reactionary remains unclear.
