This study was survey research by retrospective study aimed to evaluate patients with dysphagia without esophageal obstruction using high-resolution esophageal motility and esophageal sphincter contraction measurements at Maharat Nakhon Ratchasima Hospital. The sample consisted of 65 patients with dysphagia without esophageal obstruction at Maharat Nakhon Ratchasima Hospital during 2023-2025. Data were collected from medical records and analyzed using descriptive and inferential statistics.
The study found that esophageal function tests to detect esophageal dysfunction were normal in 18 patients (27.7%), and 47 patients (72.3%) had esophageal dysfunction. The most common conditions in this study were esophageal sphincter insufficiency (28 patients (43.1%), esophageal dystonia (4 patients (6.2%), esophageal dystonia (5 patients (7.7%), severe esophageal dystonia (1 patient (1.5%), hypoesophageal dystonia (8 patients (12.3%), and pharyngeal dysphagia (1 patient (1.5%).
