[Comparison of the results of coronary angioplasty and stenting during one year following surgery].

The purpose of the study was to compare long-term results of angioplasty and coronary arterial stenting (CAS) depending on the initial degree of coronary arterial (CA) lesion according to morphological stenosis classification, as well as to evaluate the influence of re-stenosis on myocardial contractility dynamics, anginal recurrence rate, and exercise tolerance. The subjects, 228 men after angioplasty and 184 men after CAS with wire stents without drug coating, were included in the study between 1989 and 2005. Coronarography was repeated in 358 patients one year after surgery.

[Importance of some apudocytes in gastric ulcer bleeding prediction].

In 6 patients with uncomplicated gastric ulcer (GU) and 8 patients with GU complicated by acute bleeding morphohistochemical and ultrastructural analysis of apudocytes of gastric mucous membrane in the ulcer, periulcer and remote zone was carried out with detection of morphofunctional changes predicting ulcer bleeding. It is established that G- and ECL-apudocytes hyperplasia and hyperfunction in these zones have stable, irreversible nature in gastric ulcer bleeding, and are reliable prognostic criteria of this complication.

[Importance of the morphofunctional status of APUD cells in the prognosis of duodenal ulcer hemorrhage].

In 24 patients with uncomplicated duodenal ulcer and 40 patients with acute bleeding duodenal ulcer morphofunctional status of the local paraendocrine adjusting system of the duodenal mucous membrane in the periulcer, ulcer and remote zones was studied with histochemical and electron-microscopic techniques. It is established, that ECL- and G-apudocytes hyperplasia and hyperfunction and vice versa D-cells reduction of the number and suppression of the secretory activity are reliable prognostic criteria of duodenal ulcer bleeding.

[Results of stomach resection by Billroth II with compression gastroenteroanastomosis].

Two methods of resection of the stomach by Billroth II were developed with creation of transversal termino-lateral gastroenteroanastomosis (TTLGEA) and transversal latero-lateral gastroenteroanastomosis (TLLGEA) using compression implant from nickel-titan alloy which possessed "memory of the form" (IMF). 231 resections of the stomach by Billroth II were carried out with formation TTLGEA in 181 cases and TLLGEA in 50 cases. Complications after these operations with compression gastroenteroanastomosis were studied as well as endoscopic and roentgenologic picture of the anastomosis in early postoperative period.

[Diagnosis and treatment of complications of selective proximal vagotomy].

The authors analyse the causes of 170 (38.3%) complications which occurred after 435 interventions for selective proximal vagotomy (SPV) with or without a stomach-draining operation. Specific complications were encountered in 31.
