Abstrakt: Achalasia is a rare esophageal motility disorder characterized by lack of primary peristalsis and a poorly relaxing lower esophageal sphincter. This disease process can be examined several ways and these evaluations can offer complementary information. There are three manometric subtypes of achalasia, with differing appearances on esophagram. Differentiating them is clinically important, because treatment for the subtypes varies. Timed barium esophagram (TBE) is a simple test to quantitatively evaluate esophageal emptying. TBE can be used to diagnose achalasia and assess treatment response. Considerable variation in the TBE protocol exist in the literature. We propose a standardized approach for TBE to allow for comparison across institutions.
