title: [Hernia hiatal. Detection of gastroesophageal reflux with the telemetric Heidelberg capsule].
abstract: 120 patients with upper gastrointestinal symptoms were studied and submitted to gastric secretory tests, upper gastrointestinal X-rays and endoscopy. Gastroesophageal reflux was assessed by means of a Heidelberg telemetric capsule. 60 patients had hiatal hernia. Gastroesophageal reflux was present in 63.33%. 76% of the patients with hiatal hernia had gastroesophageal reflux, especially on those with small hernias and on the 5th and 6th decade of life. Gastric hiperacidity facilitates the incidence and presence of reflux. X-rays and endoscopy allowed us to diagnose diseases at the gastroesophageal junction. The correlation between these 2 methods and the presence or not of reflux, allowed differentiation between patients with organic diseases and patients with "functional" symptoms.
