[The role of endoscopy in determining the indications for the surgical treatment of the Mallory-Weiss syndrome and of bleeding acute gastroduodenal ulcers].

The frequency of acute sources of bleeding has recently increased (47%) in the general picture of gastrointestinal bleedings which makes the improvement of diagnosing "acute" sources of hemorrhage and the development of more perfect methods of nonoperative hemostasis very actual. The authors believe that "Kaprofer" used in most of patients with bleedings from acute ulcers and ruptures of the gastro-esophageal zone mucosa (95%) allows the hemorrhage to be arrested. The treatment can be continued without operative interventions.
