Background: Achalasia is classified by high-resolution manometry into three subtypes, which are proposed to predict
clinical outcome.
Goals: The aim of this prospective study was to evaluate the clinical outcomes of achalasia subtypes after pneumatic
dilation, their manometric and radiologic features.
Results: Of the 53 patients, 07 (13%) were classified as subtype I, 44 (83%) as subtype II, and 2 (4%) as subtype III.
Clinical response among the subtypes were similar: 7/7 (100%) subtype I, 39/44 (88,64%) subtype II and 2/2 (100%)
subtype III. Forty-four patients were submitted to pre- and post-treatmenthigh-resolution manometry. The integrated
relaxation pressure and the basal respiratory pressure of the lower esophageal sphincter were significantly lower after
the treatment (p<0,001), with a similar d.. View More»
