Background Endoscopic ultrasonography (EUS) and high-resolution manometry (HRM) can be used in the evaluation of eosinophilic esophagitis (EoE) for frequent symptoms such as dysphagia. However, the role of these examinations is not clear. Aims The aim of this study was to objectively evaluate the subjective symptoms of EoE patients with EUS and HRM. Methods Patients who had endoscopic findings indicative of EoE and matched the number of eosinophil infiltrates used as diagnostic criteria were recruited between September 2018 and August 2019. Evaluable subjects underwent EUS and HRM and completed the Gastrointestinal Symptom Rating Scale (GSRS) questionnaire. The esophageal wall thickness (evaluated with EUS) and HRM parameters between patients with and without symptoms were retrospectively compared. Symptomatic patients were re-examined using EUS and HRM 6 months after treatment. Results A total of 35 patients (29 males, median age of 49 years) were divided into symptomatic (20 patients) and asymptomatic groups (15 patients). The esophageal wall was thicker, and the distal contractile integral (DCI) values were higher in the symptomatic group (P < 0.001). In addition, DCI values were positively correlated with esophageal wall thickness. After treatment, the GSRS scores showed an improving trend for each item. Esophageal wall thickness and DCI values were significantly decreased (Ps < 0.001). Conclusions Esophageal wall thickening and increased esophageal body pressure may be involved in subjective symptoms. In addition, treatment may reduce esophageal thickness and pressure along with improvement of subjective symptoms.

<b><i>Introduction:</i></b> Dysphagia is a common symptom that occurs in patients with diabetes mellitus (DM). There have been few prospective observational studies on esophageal motility disorders in DM using high-resolution manometry (HRM). This study aimed to clarify the characteristics of esophageal motility disorders using HRM in patients with dysphagia and compare them between DM and non-DM patients. <b><i>Methods:</i></b> Patients with dysphagia were prospectively recruited between October 2018 and July 2019. Patients (<i>n</i> = 89) underwent esophagogastroduodenoscopy and HRM and completed the Gastrointestinal Symptom Rating Scale (GSRS) questionnaire. Manometry parameters and motility disorder classifications were compared between DM and non-DM patients. We also investigated the differences in clinical backgrounds and questionnaire scores among DM patients with normal and abnormal manometry results. <b><i>Results:</i></b> A higher prevalence of esophageal motility disorder was observed in DM patients (60%, 21/35) compared to non-DM patients (29.6%, 16/54) (<i>p</i> = 0.001). The prevalence of minor disorders such as ineffective esophageal motor disorder and fragmented peristalsis was significantly higher (45 vs. 11%), and the distal contractile integral, integrated relaxation pressure, and contractile front velocity values were lower in the DM group. Among DM patients, those with abnormal esophageal motility had a significantly higher prevalence of neuropathy, retinopathy, and nephropathy, as well as higher reflux or constipation scores on the GSRS, than those with normal results. <b><i>Conclusions:</i></b> Among patients with dysphagia, the frequency of minor esophageal motility disorders was higher in DM patients than in non-DM patients. Abnormal esophageal motility related to poor esophageal clearance was associated with higher prevalence of diabetic complications.

A 65-year-old woman with a history of treatment for splenic marginal zone B-cell lymphoma and gastric mucosa-associated lymphoid tissue (MALT) lymphoma underwent esophagogastroduodenoscopy. A reddish elevated lesion was found in the fundus of the stomach. On image-enhanced endoscopy, several findings, such as glandular structures of varying sizes suggesting well-differentiated adenocarcinoma, pruned blood vessels, and dilated blood vessels in deeper mucosa suggesting MALT lymphoma, were observed. The final pathological diagnosis after surgical resection was collision tumors of well-differentiated adenocarcinoma and MALT lymphoma. The features of both tumors could be observed simultaneously with image-enhanced endoscopy.
