ABSTRACT
As a result of selective biopsy of gastric polyps 77 hyperplastic, 36 hyperplasiogenous and 11 adenomas were found. By the introduction of endoscopic polypectomy 42 polyps were resected in toto and 39 could be removed. The histological result of the whole polyp showed that the most frequent form is the hyperplastiougenous type with 42.5%. Comparisons of the histological results of the whole polyp with the particles of the biopsy (selective biopsy) differ in 40%. The combination of the results of antral polyposis (type II) with those of an adenocarcinoma in the material affirmed our thesis that the hyperplasiogenous polyp is an indicator for a higher tendency of the gastric mucosa for developing a carcinoma. Follow-up observations of pseudopolypoid folts showed a spontaneous regression of about 50% after one year and of about 75% after four years. In this article tendencies regarding the relation between the patients age, the growth speed and the histological structure of the gastric polyps are discussed.

By anamnestic inquiry and investigation for HBsAg and anti-HBs (RIA) of 120 staff members from 18 endoscopic centers, we found reference to remarkable spread of hepatitis B. Its incidence in endoscopic staff is unambiguously higher than in personal of internal wards. So, 8.3 per cent of endoscopic workers were positive for HBsAg, and anti-HBs was found in 29.7 per cent of them. This study accentuates the high danger by gastro-enterologic patients, who not rarely are HBsAg-positive and infectious. Preventive measures are recommended.

Important experiences are reported from an analysis of 500 examinations. The ERCP gives eminent possibilities for the improvement of the pre- and postoperative diagnostics of the bile ducts, particularly in unclear cholestasis and in conditions after operations of the bile ducts. The ERCP is little suited for the early diagnosis of the carcinoma of the pancreas and for the ascertainment of the diagnosis in easy and moderate forms of chronic pancreatitis. Of particular value is the possibility to clear the causes of recidivations of pancreatitis as well as of complications of the severe chronic pancreatitis with regard to operative consequences.

The establishment of the motor activity of the gastrointestinal tract is difficult to be performed. The method of electrogastroenterography gives an evidence through an indirect registration of the summation vectors of the action potential. In patients with ventricular ulcer a statistically certain retardation of the changes of the potential/min. in comparison to a control group is to be proved. In patients with duodenal ulcer in the same way a trend is to be observed. It is especially referred to the importance of these examination methods in the sense of examinations of the course of the disease.
