[Incidence of peptic ulcer in diabetic disease: a clinic-epidemiological study].

We have investigated in 400 patients, 159 male and 241 female, mean age 58 years, with type 2 diabetes, the incidence of peptic ulcer and on 127 patients with peptic ulcer, the incidence of diabetes mellitus. In conclusion the incidence of peptic ulcer is no more than 3,9% in diabetic patients. In peptic ulcer the female to male ratio is 1:0,9. The seat of the ulcer is resulted to be in ratio of 1,4:1 more in the duodenal tract than in the gastric tract. The result are attributed to the increased secretion of the gastrointestinal hormones (Bombesin and Somatostatin) in the diabetic patients. However the neuromodulator of gastrointestinal hormones release is mediated of the Dorsal Motor nucleus of the Vagus nerve connected to the endocrine pancreas exclusively via vagal fibers and has a role in neurally mediated insulin release.
