Esophageal manometry examines the pressure profiles of the tubular esophagus and of the esophageal sphincters during resting conditions and in response to swallowing. It is regarded as the reference method for detection of esophageal motility disturbances but, up to date, performance of the procedure is not standardized among centers. This review depicts the recommendations of the German Societies for Neurogastroenterology and Motility, for Digestive and Metabolic Disturbances and for General and Visceral Surgery on indications, performance and analysis of conventional esophageal manometry. In addition to concise recommendations we give detailed background information so that the article can serve as a practical guideline for inexperienced investigators as well as an exensive review for the experienced one. Moreover, recommendations on the use of newer and/or supplementary diagnostic techniques, that is long-term and high resolution manometry as well as esophageal impedance measurements are also given.
