[The intraabdominal pressure rising as a risk factor of posttraumatic pancreatitis occurrence].

The results of experimental investigation, conducted on white Wistar rats, are adduced. The influence of intraabdominal pressure change on pancreatic parenchyma were studied in the animals. The data obtained witness the unfavourable influence of the raised intraabdominal pressure on pancreatic gland, manifesting by an acute pancreatitis occurrence.

[The diagnosis and treatment of a malignant stomach ulcer].

The results of treatment have been analyzed in 587 patients with stomach ulcer in 52 of whom ulcer was found to be malign. Methods of diagnosing of ulcer malignization are not reliable. Difficulties in differential histodiagnosis, absence of trustworthy diagnostic tests as well as advisability of additional mucus assays are underlined.

[The surgical treatment of malignant stomach ulcers].

The authors analyse the specific features of the clinical picture, diagnosis, pathomorphological changes and surgical treatment in 52 patients with gastric ulcer which underwent malignant degeneration. It is noted that malignancy occurs most frequently in close vicinity to the ulcerative defect and rarely in the mucosa beyond the ulcer. The morphostructural reorganizations are determined to a certain degree by the peculiarities of extension of the tumor along the mucosa and the organ as a whole.
