Abstract

High-resolution manometry (HRM) is the gold standard for diagnosing esophageal motility disorders, yet it can be poorly tolerated and technically challenging. Epiphrenic diverticula (ED) are located in the distal esophagus and are associated with underlying motility disorders. ED patients (2008–2022) were retrospectively compared to achalasia patients (2008–2022) and all other patients (2021–2022) who underwent HRM at a single center. Complete success was defined as at least 7 interpretable swallows including measurements throughout the esophagus into the stomach. HRM studies involving children, previously treated achalasia, and sedation or endoscopic-assistance were excluded. 20 ED patients (mean age 66; 60% female) were compared to 76 achalasia patients and 199 controls. HRM was completely successful in 70.0% of ED patients, 85.5% of achalasia (p = 0.106 vs ED), and 91.0% of controls (p = 0.004 vs ED). Most failures in the ED and achalasia groups were due to inability to traverse the esophagogastric junction (EGJ), while patient intolerance was the main reason in controls. Half of the ED group had motility disorders (25% achalasia, 15% hypercontractile esophagus, 10% absent contractility). Large diverticulum size was inversely associated with technical success compared to small diverticulum size (40% vs 100%, p = 0.013), while the presence of a motility disorder did not significantly affect success (60% vs 88.9%, p = 0.303). In conclusion, ED is a predictor of unsuccessful HRM. This appears to be mainly related to an inability to traverse the EGJ due to the size of the diverticulum. Consideration should be given to alternative means of evaluating motility, such as endoscopy-assisted HRM, given the high likelihood of failure with traditional HRM.
