CHICAGO CLASSIFICATION v4.0
Achalasie de type I, II et III
La manométrie haute résolution distingue trois sous-types pouvant influencer le choix du traitement.
Brouillon éditorial · validation médicale requise avant publicationImportant distinction
Type I, II and III are not diagnosed from symptoms. Subtype is defined by high-resolution manometry (HRM).
TYPE I
Classic achalasia
Abnormal median IRP + 100% failed peristalsis, without the prominent panesophageal pressurisation of Type II.

TYPE II
Panesophageal pressurisation
Abnormal median IRP + 100% failed peristalsis + panesophageal pressurisation in ≥20% of swallows.
Full Type II guide →
TYPE III
Spastic achalasia
Abnormal median IRP + premature/spastic contractions in ≥20% of swallows; no normal peristalsis.
Full Type III guide →WHY DOES SUBTYPE MATTER FOR TREATMENT?
Subtype does not determine treatment by itself, but it is an important part of the decision.
POEM · Heller · PD
Several effective options exist; age, anatomy, reflux priorities and centre expertise guide individualisation.
POEM often stands out
Because the spastic segment may require a longer myotomy, current SAGES guidance favours POEM.
