Pictorial Presentation

ABSTRACT High resolution manometry changed several esophageal motility paradigms. The 3.0 Chicago Classification defined manometric criteria for named esophageal motility disorders. We present a pictorial atlas of motility disorders. Achalasia types, esophagogastric junction obstruction, absent contractility, distal esophageal spasm, hypercontractile esophagus (jackhammer), ineffective esophageal motility, and fragmented peristalsis are depicted with high-resolution manometry plots.

Background: Eosinophilic esophagitis (EoE) presents with dysphagia, but data about motility patterns using high-resolution manometry (HRM) are rare. We aimed at evaluating esophageal motility patterns in EoE and their correlation to endoscopic and dysphagia scores. Methods: Twenty-six EoE patients and 23 controls were included after 4 weeks of treatment with proton pump inhibitors. Dysphagia and endoscopic scores were evaluated before performing HRM. EoE patients were classified to have fibrostenotic (FS) or inflammatory (IF) type. HRM analysis was performed according to the Chicago classification (CC) system. Results: According to the CC, the HRM findings in EoE and controls were normal in 11 (42%) and 20 (88.5%), p < 0.0001. Weak and failed peristaltic integrity was only seen in EoE patients (failed 1/2.7%, weak 7/26.9%, p = 0.004). Of the EoE patients, 17 had IF and 9 presented with FS type. HRM parameters showed no differences according to the EoE subtype. The endoscopic score in the FS subtype was significantly higher than in EoE with IF subtype (5.33 vs. 3.58, p = 0.001). No significant difference was seen in dysphagia scores in EoE subtypes. Discussion: HRM findings in EoE are often diagnostic, but they are non-specific and do not correlate with the severity of dysphagia or endoscopic appearance. The clinical impact of HRM in EoE needs further evaluation.

ABSTRACT Introduction: High resolution manometry is the current technology used to the study of esophageal motility and is replacing conventional manometry in important centers for esophageal motility with parameters used on esophageal motility, following the Chicago Classification. This classification unifies high resolution manometry interpretation and classifies esophageal disorders. Objective: This review shows, in a pictorial presentation, the new parameters established by the Chicago Classification, version 3.0, aimed to allow an easy comprehension and interpretation of high resolution manometry. Methods: Esophageal manometries performed by the authors were reviewed to select illustrative tracings representing Chicago Classification parameters. Results: The parameters are: Esophagogastric Morphology, that classifies this junction according to its physiology and anatomy; Integrated Relaxation Pressure, that measures the lower esophageal sphincter relaxation; Distal Contractile Integral, that evaluates the contraction vigor of each wave; and, Distal Latency, that measures the peristalsis velocity from the beginning of the swallow to the epiphrenic ampulla. Conclusion: Clinical applications of these new concepts is still under evaluation.
