[Treatment of patients with acute gastrointestinal hemorrhages at a specialized center].

The work has shown that concentrating the patients with acute gastro-intestinal bleedings at surgical hospitals having qualified surgeons, auxiliary services and necessary equipment can give a considerable improvement of differential diagnosis of the source of bleeding in the acute period, higher surgical activity in the ulcer on cancer nature of the bleeding, better results of both the operative and conservative methods of treatment.

[Reutilization of the right-side approach in commissurotomy in recurrent mitral stenosis].

Based on histotopographic studies of heart specimens taken from patients died after commissurotomy with a right-side approach, and the experience with eleven mitral commissurotomies using an access via the interatrial septum repeatedly, it is concluded that a close mitral commissurotomy for reccurrent mitral stenosis with the repeat use of a right-side approach seems to be anatomically grounded and easy to be performed from the point of view of the operative technic. This intervention should be accomplished in patients with recurrent mitral stenosis, previously operated upon with a right-side access. The opportunities of reused right-side approach offer prerequisites for its wider application in primary commissurotomy.
