Prevention of gastrointestinal bleeding in patients operated on the arteries of the lower extremities for critical ischemia

Abstract

The purpose of the study. To determine the frequency of occurrence and prevention measures of erosive and ulcerative lesions of the proximal gastrointestinal tract in patients operated for critical ischemia with a diagnosis of obliterating atherosclerosis of the arteries of the lower extremities. Materials and methods. The examination included patients with lower limb ischemia - III-IV stage of ischemia according to the Fontaine-Pokrovsky classification. The patients were divided into 2 groups: the control group, where treatment was carried out according to the recommendations: HP diagnosis (express test) was carried out only with an endoscopic picture of gastric ulcer and duodenal ulcer, as well as the main group, in which HP diagnosis was carried out totally with fibrogastroduodenoscopy and a standard three-component eradication scheme was prescribed for at least 14 days when bacterial contamination of the gastric mucosa was detected. Results. In all cases, endoscopic changes characteristic of gastritis were registered in patients of the first group. Of the eight patients (100%), two (25%) were diagnosed with single erosions in the distal parts of the stomach, one patient (12.5%) had atrophic gastritis, and the remaining 5 (62.5%) patients had hyperemia of the antral and prepiloric mucosa. In patients of the second group, there were no changes in FGDS in one patient (25%), foci of mucosal atrophy were diagnosed in two patients (50%), and single erosions in one (25%). Conclusion. Among patients with peripheral artery diseases accompanied by critical ischemia, by the time they seek specialized medical care, there are no healthy or close to such persons with unchanged mucous membrane of the proximal parts. In the high-risk groups for the occurrence of gastrointestinal bleeding, a complex effect on aggression factors is necessary
