[Erosion of the gastroduodenal zone: an independent nosological form or an ulcer phase?].

We examined 215 patients, 98 of them being with gastric and duodenal erosions, 52 being with erosions of the gastroduodenal zone combined with duodenal ulcers, and 65 being with duodenal ulcers. Endoscopic, radiological, biochemical, pH measurement studies and abdominal gastroduodenal manometry were used for the evaluation of the functional state of the gastroduodenal system. It was established that impaired pyloric and cardiac functions, duodenogastric reflux, dyskinesia of the stomach and duodenum, stomach deformation and gastroduodenoptosis are observed more frequently in cases of erosive lesions as compared to ulcers. The obtained data allow us to assume that gastric and duodenal erosions are an independent nosological form with their own pathogenic mechanisms, clinical presentation and complications including ulcers.
