Background During the natural course of eosinophilic esophagitis (EoE), the risk for esophageal stricture formation increases. It remains unknown whether motility abnormalities in EoE also develop over time. We aimed to determine the relationship between disease duration, clinical characteristics, and manometric pattern of EoE patients. Methods We compared esophageal high‐resolution manometry (HRM) measurements of 31 adult EoE patients with HRM data from 31 GERD controls and 31 healthy controls. Subsequently, we assessed differences in disease duration and clinical characteristics between EoE patients with normal and those with abnormal esophageal motility. Key Results In EoE patients, peristaltic integrity was more frequently failed (12 vs 6%) or weak (27 vs 15%; p < 0.001) compared with healthy controls; however, this pattern was also seen in GERD controls (failed 14%, weak 27%). We found no differences regarding symptoms and signs of EoE between EoE patients with normal (42%) and abnormal motility (58%). However, disease duration was longer in EoE patients with abnormal motility than in those with normal motility (13 (6–18) years vs 4 (1–11) years; p < 0.05). In EoE, but not GERD, disease duration was identified as a risk factor for abnormal motility (OR for each year 1.142; 95% CI 1.004–1.299), and with longer disease duration, the prevalence of abnormal motility increased from 36% (duration 0–5 years) to 83% (duration ≥16 years; p < 0.05). Conclusions & Inferences Weak and failed peristaltic integrity are more often present in adult EoE patients than in healthy controls. The prevalence of manometric abnormalities in EoE patients increases with longer disease duration. The aim of this study was to determine the relationships between disease duration, manometric patterns, and clinical characteristics in 31 adult EoE patients. Disease duration was much longer in EoE patients with abnormal motility than in those with normal motility (13 (6–18) years vs 4 (1–11) years; p < 0.05). Disease duration was identified as a risk factor for abnormal motility (OR for each year 1.142; 95% CI 1.004–1.299), and with longer disease duration, the prevalence of abnormal motility increased from 36% (disease duration 0–5 years) to 83% (disease duration ≥16 years; p < 0.05).
