Achalasia diagnosed despite normal integrated relaxation pressure responds favorably to therapy

Background Achalasia diagnosis requires elevated integrated relaxation pressure (IRP; manometric marker of lower esophageal sphincter [LES] relaxation). Yet, some patients exhibit clinical features of achalasia despite normal IRP and have LES dysfunction demonstrable by other means. We hypothesized these patients to exhibit equivalent therapeutic response compared to standard achalasia patients. Methods Symptomatic achalasia‐like cases, despite...
