“…HRM was carried out using Starlet® (Star Medical Co., Ltd. Tokyo, Japan). The Starlet HRM system has a catheter with 36-channel solid-state sensors spaced at 1-cm intervals (Unisensor AG, Attikon, Switzerland) [15]. The outer diameter of the thinnest part of the catheter was 3.8 by 5.4 mm of each transducer site.…”

Background/Aims: Endoscopic submucosal dissection (ESD) for superficial esophageal cancer is sometimes extensive, and in our experience, patients not infrequently present with dysphagia after ESD even in the absence of esophageal stricture. The aim of this study was to evaluate esophageal motility using high-resolution manometry (HRM) in patients with and without dysphagia after extensive circumferential ESD. Methods: HRM was performed in a total of 52 patients who had undergone ESD for superficial esophageal cancer and a mucosal defect after ESD exceeded more than two-thirds of the esophageal circumference. The frequency and type of esophageal dysmotility and the relationship between esophageal motility and dysphagia were evaluated. Results: Esophageal dysmotility was observed in 13 patients (25%): jackhammer esophagus in 4, esophagogastric junction outflow obstruction in 4, absent contractility in 2, and distal esophageal spasm, ineffective esophageal motility, and fragmented peristalsis in 1 patient each. Of the 22 patients with dysphagia after ESD, 9 (41%) had esophageal dysmotility. Of the 30 patients without dysphagia after ESD, 4 (13%) had esophageal dysmotility. The relationship between dysmotility and dysphagia was significant (p = 0.025). Conclusions: Esophageal dysmotility exists in approximately one-quarter of patients after extensive circumferential ESD, which is associated with dysphagia in the absence of esophageal stricture.

“…pHRM has the advantage of a more durable probe. Of late, 36-channel perfusion catheters have been developed, which obtain pressure profiles with improved quality and accuracy (37). However, perfusion catheter accuracy is inferior to that of sHRM in the study of the UES.…”

Eosinophilic esophagitis is a chronic immunoallergic inflammatory disease of the esophagus that represents a major cause of digestive morbidity among the pediatric and young adult populations. Despite the fact that key symptoms in adults include dysphagia and food impaction, many patients lack structural changes in the esophagus to account for their complaints, which suggests the presence of underlying motor disorders and esophageal distensibility impairment. In the last few years the esophageal motility of these patients has been studied using various approaches, most particularly high-resolution manometry, ambulatory manometry, and impedance planimetry. This review focuses on the most relevant findings and scientific evidence regarding esophageal motor disorders in eosinophilic esophagitis.
