The role of duodenal erosions in the occurrence of upper gastrointestinal haemorrhage.

It is well known that gastric erosions and the so called erosive gastritis, cause about 20-30% of massive upper gastrointestinal haemorrhage. Our endoscopic material was examined in order to answer the following questions: at what ratio duodenal erosions induced massive bleeding, what their emergence can be attributed to, what connection may be found between duodenal ulcers and duodenal erosions and what is the rate of recovery of such patients. We found that: 1) duodenal erosions may occur together with gastric erosions, therefore they can jointly induce massive bleeding; 2) duodenal erosions may be associated with duodenal ulcer but haemorrhage originates from the erosion and the ulcer itself does not bleed; 3) duodenal erosion in itself might induce bleeding, 4) the intensity of bleeding, if there is no haemorrhage from other places, is not so severe, as the one originating from gastric erosions, and with the application of conservative treatment it usually stops within a short period of time; 5) the inducing factor is generally massive alcohol consumption; drug intake is rare as a cause for duodenal erosions.

Mass screening for colorectal cancer in Hungary.

Haemoccult screening for colorectal tumours was carried out in Hungary in small cities and villages around Budapest. Haemoccult slides were supplied to 17,662 individuals over 40 years of age, and 15,431 (87%) were returned. Of these, 346 (2.

Long-term results of vagotomy in the light of endoscopy.

In the period 1968 to 1973, 177 patients were vagotomized. Endoscopy had to be performed because of definite symptoms in 37 of these patients on 56 occasions between 1971 and 1979. Vagotomy had been selective in 22, truncal in 15 cases.
