[Results of 189 Visotrast studies in the differential diagnosis of acute intestinal obstruction].

In cases of an acute abdomen, bowel obstruction cannot always be excluded. In this case the administration of oral water soluble contrast media (Visotrast) is helpful. On the basis of their experience with 189 patients who underwent gastrointestinal x-ray examination with Visotrast (157 spontaneous mechanical obstruction, 32 postoperative ileus) the authors recommend this diagnostic procedure in difficult situations.

[Pathologic-anatomic findings in 1,300 trial excisions from the female and male breast].

1 300 diagnostic biopsies of men and women suffering from breast tumours were performed. The findings are dealt with and coincidence of benign and malignant lesions, accuracy of different diagnostic methods, age of patients, diagnostic neglect, risk factors are analysed. The guiding lines indicating diagnostic biopsies are defined.

[Cholelithiasis after stomach resection?].

The prevalence of all forms of cholelithiasis in patients suffering from peptic ulceration and following partial gastric resection has been examined on the basis of analysing 28 204 autopsies from 1953 to 1979. The review of the post-mortem reports proves considerable gallstone incidence of 30,84% in the above mentioned groups of patients. There was no statistic difference with regard to the prevalence of gallstone formation in the collective as a whole, in the ulcer group or the group with partial gastric resection.
