Core Tip
Core tip: High resolution manometry is a new technology with clear advantages over conventional manometry. It is unclear; however, if new parameters created after this technology can be obtained by conventional manometry especially in achalasia cases. We found that conventional manometry is still valuable to classify achalasia according to the Chicago classification but high resolution manometry permits a better study of the lower esophageal sphincter.
