Abstract

Background: High-resolution manometry (HRM) is performed for evaluation of esophageal symptoms, but patient outcome is unclear when no actionable motor disorder is identified. We evaluated long-term symptomatic outcome of patients with nonactionable HRM findings.

Methods: Patients who underwent (HRM) studies in 2006-2008 were tracked. Patients with achalasia spectrum disorders, foregut surgery before or after HRM, and incomplete symptom documentation were excluded. Symptom questionnaires assessing dominant symptom intensity (DSI, product of symptom severity and frequency recorded on 5-point Likert scales) and global symptom severity (GSS, from 10 cm visual analog scale) were repeated. Change in symptom burden was compared against HRM motor findings using Chicago Classification 4.0 (CCv4.0), applied retroactively to 2006-2008 data.

Key results: Overall, 134 patients (median age 68 years, 64.5% female) could be contacted. The majority (73.1%) had normal motility; others had ineffective esophageal motility (8.2%), esophagogastric junction outflow obstruction (13.4%), hypercontractile esophagus (3.0%), or absent contractility (2.2%), none managed invasively. Over 15 years of follow-up, DSI decreased from 8.0 (4.0-16.0) to 1.0 (0.0-6.0) (p < 0.001) and GSS improved from 5.5 (3.3-7.7) to 2.0 (0.0-4.0) (p < 0.001); improvement was consistent across CCv4.0 diagnoses and subgroups. The majority (82.8%) reported improvement over time, and antisecretory medication was the most effective intervention (83.0% improvement). There was no difference in medication efficacy (p = 0.75) or improvement in symptoms (p = 0.20) based on CCv4 diagnosis.

Conclusions and inferences: Esophageal symptoms improve with conservative symptomatic management over long-term follow-up when no conclusive obstructive motor disorders or achalasia spectrum disorders are found on HRM.
