Abstract

Esophageal manometry represents the gold standard technique for the diagnosis of esophageal achalasia because it can detect both the lack of lower esophageal sphincter (LES) relaxation and abnormal peristalsis. From the manometric standpoint, cases of achalasia can be segregated on the grounds of three clinically relevant patterns according to the Chicago Classification v3.0. It is currently unclear whether they represent distinct entities or are part of a disease continuum with the possibility of transition from a pattern to another one. The four cases described in the present report could provide further insights on this topic because the manometric pattern changed from type III to type II in all patients-without any invasive treatment. The cases described here support the hypothesis that the different manometric patterns of achalasia represent different stages in the evolution of the same disease, type III being the early stage, type II an intermediate stage, and type I probably the end stage of achalasia.
