title: Studies in esophageal motility: five year clinical experience in a Canadian tertiary care hospital.
abstract: A total of 661 esophageal motility studies were performed in 568 patients over a five year period in a tertiary care hospital. Patients referred for investigation generally presented with one of three symptoms: dysphagia, reflux or chest pain. Dysphagia was more closely identified with organic esophageal dysfunction than other symptoms. Normal studies were recorded in 201 instances (30%). Studies demonstrating either a major or minor non-specific motor disorder were found in 380 cases (58%). Achalasia was found in 48 patients who underwent 65 procedures (10%). Scleroderma was diagnosed in 7 patients (1%). Elderly patients were not found to have diminished esophageal function when compared to a young group.
