Summary Introduction: esophageal manometry is the chosen procedure or gold standard technique for the diagnosis of esophageal motor disorders. Objectives: to assess the usefulness of esophageal manometry (EMS), to examine manometry diagnosis according to symptoms and to compare results with published data. Method: we analyzed the medical records and manometric tracings of 104 patients at the Gastroenterology Clinic of the Clinicas University Hospital, between March 2005 and October 2007, according to the symptoms that motivated the study: dysphagia (54), gastroesophageal reflux disease (GER) (43), and non-cardiac chest-pain (7). Patients with endoscopic and heart alterations were not included in the study. Results: we found manometric alterations in 75.9% of patients with dysphagia, being achalasia the most frequent disorder. In the gastroesophageal reflux disease group (GER), 69.8 % of manometries were abnormal, being ineffective peristalsis the most frequent alteration. In the chest pain group, manometric alterations added up to 71.4 %. Diagnostic usefulness of esophageal manometry was 73.1% (76/104; IC95%: 63,5-81,3). Conclusions: esophageal manomery in this series had a high diagnostic usefulness (73,1%), which may be compared to other published studies. Manometric diagnosis for each group agree with those reportes by other authors in Europe and United States, there being no studies published in Latin America to assess the three groups included in this study. Despite there being no meaningful differences, EMS had a higher diagnostic usefulness in the dysphagia group.
