Conclusive Diagnosis

Ineffective esophageal motility (IEM) is a hypomotility disorder with decreased contraction vigor and normally relaxing lower esophageal sphincter. Although IEM has been associated with poor esophageal clearance and gastroesophageal reflux, it is also seen in asymptomatic subjects and is often of unclear clinical significance. The Chicago classification version 4.0 updated the diagnostic threshold to require >70% weak or fragmented swallows or ≥50% failed swallows for a conclusive diagnosis of IEM. Provocation testing are recommended in borderline cases to assess clinical relevance. Prospective trials are needed to further refine the diagnostic criteria, understand the pathophysiology, and develop an effective treatment for IEM.

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.
