RESUMO
Complex study of the frequency and intensity of the duodenogastric reflux in 468 patients with peptic ulcer is analysed; 372 had duodenal ulcer and 96 had gastric ulcer. The authors give the characteristics of the diagnostic possibilities of X-ray, endoscopic, ionomanometric, and aspiration (radionuclide and biochemical) methods of examination of duodenal regurgitation. They proved the relation of the frequency and intensity of the duodenal regurgitation to the type of the ulcer and the phase of its course (exacerbation or remission), the condition of the pyloric closure function, and disorders of duodenal motor activity. The sequelae of long-term duodenogastric reflux are analysed; it is shown that patients must be examined in the preoperative period in the phase of remission so as to gain the true values of intensity of the reflux for its subsequent correction.
