BACKGROUND: Thickening of the esophageal wall in patients with eosinophilic esophagitis (EoE) and gastro-esophageal reflux disease (GERD) has been shown in studies using endoscopic ultrasound (EUS). We hypothesise that transmural inflammation in EoE results in prominent esophageal wall thickening compared with the mucosal inflammation in GERD. The aim of this study was to compare the relationship among dysphagia, endoscopic appearance, wall thickness, histology, and motility in EoE and GORD.
METHODS: EoE and GERD patients were prospectively studied between February 2012 and April 2021. Patients were studied on 2 separate occasions with endoscopy, EUS and mucosal biopsies, followed by high-resolution manometry. Epidemiology and dysphagia data were obtained.
RESULTS: A total of 45 patients (31 EoE, 14 GERD) were included. There were no significant differences in age, sex, duration of disease and presence of esophageal motility disorders. EoE patients had a higher dysphagia score (P < 0.001), EREFS score (P < 0.001) and peak eosinophil count (P < 0.001) compared with GERD patients. Thickness of the submucosa in the distal esophagus in EoE was significantly higher than GERD (P = 0.003) and positively correlated with duration of disease (P = 0.01, R = 0.67). Positive correlation was also found between dysphagia score and distal total esophageal wall thickness (P = 0.03, R = 0.39) in EoE patients. No correlation was found between these variables in GERD patients.
CONCLUSION: Distal esophageal wall thickness positively correlates with dysphagia score in EoE but not GERD. This appears to be related to the composition of the submucosa which can be identified using EUS.
