Dynamic esophageal scintigraphy in patients with chronic obstructive bronchopulmonary disease

The authors monitored by means of dynamic esophageal scintigraphy the rate of transport via esophagus, antiperistalsis and the retention of activity in esophagus in the group of 58 patients (37 control patients and 21 examined patients) with chronic obstructive bronchopulmonary disease. The significantly longer time of transport through esophagus compared to the control group (p〈0.05%) was observed in the patients suffering from chronic bronchopulmonary disease. A frequent occurrence of antiperistalsis was found, especially in the lower and the central sections of esophagus, the retention of activity was observed rarely. (Gastroenterol.
