Gas jet transection of liver parenchima: experimental research.

Background: There exists a great variety of liver parenchyma transection techniques. The objective of this research is to develop a new method of liver transection, and to compare it with the traditional ones.

Methods: An original gas jet transection method of biological tissues and the apparatus "Pneumojet" to make the method practicable were developed in our institute.

[Surgical treatment of a solitary hepatic abscess].

Retrospective analysis of the treatment results of 120 patients, suffering solitary hepatic abscess (SHA), was conducted. The sanation methods, in accordance to technology, the treatment impact intensity and aggressiveness, may be divided on three lines: aspirational, draining and resectional. The method of sanation is selected on the background of morphological peculiarities of abscess--its sizes, by presence of sequesters, divisioning septs, dense rigid capsule, grade of periprocess.

Spontaneous emission of singlet oxygen near dielectric nano-objects and radiative diagnostics of bio-objects.

We investigate modifications of a spontaneous emission rate near the surface of the hemoglobin-like dielectric structure in the long-wavelength limit. We demonstrate that notwithstanding the small size of the dielectric structure, an influence of its shape cannot be neglected. Even for moderate dielectric contrasts one can expect having significant and detectable enhancement or suppression of the spontaneous emission rate near the surface of the biological macromolecule.

[Application of mini-invasive technologies in the treatment of gastrointestinal bezoars].

The data on etiology, clinical signs, diagnosis and variety of approaches to the treatment of gastrointestinal bezoars were presented, basing on the worldwide literature analysis. The results of surgical treatment of patients for bezoars, using miniinvasive methods, are presented.

[The surgical risk factors in the use of laparoscopic cholecystectomy].

The increased risk factors--gender, age of the patient, the cholelithic disease existence duration, the acuteness of inflammation, the operations performed earlier on the abdominal cavity organs, influencing the laparoscopic cholecystectomy conduction for Courvoisier's gallbladder--were analyzed. The increase of intraoperative complications occurrence (hemorrhage, perforation of gallbladder, the outhepatic biliary ducts) in patients of elder age with durable disease was noted.

[Acute biliary pancreatitis. Diagnosis and course of treatment].

The results of surgical treatment of 320 patients with an acute biliary pancreatitis are analysed. The therapeutic-tactical algorythm, using miniinvasive endoscopical interventions, is elaborated. Mortality for pancreatitis in systemic-toxical phase have constituted 10.

Tendencies in the development of gall-stone surgery with high medical technologies applied.

At present the endoscopic methods are the most acceptable in the treatment of gall-stone disease and its complications. Obstructions of terminal part of common bile duct and bile duct stones are removed by means of endoscopic sphincterotomy. Cholecystectomy is performed by means of laparoscope.

[The choice of the procedure for endoscopic decompression in obstruction of the distal choledochus].

The employment of endoscopic methods in 399 patients for preoperative decompression of the biliary system in mechanical jaundice was analyzed. Positive and negative aspects of each of the methods were established and indications for using them were determined.

[Diagnostic and therapeutic tactics in various forms of acute pancreatitis].

Course of the different forms of acute pancreatitis was studied in 234 patients. The therapeutico-tactical approach was individualized on the basis of considering the form of pancreatitis, its etiology, and four groups of the patients were distinguished. Conservative therapy with the wide use of therapeutic endoscopy permits in the majority of cases to achieve an abortive course of the disease.

[Diagnosis and treatment of obstructive jaundice of non-neoplastic origin].

The results of surgical treatment of 853 patients with obstructive jaundice of non-tumor genesis and initial bilirubin level in the blood of 100 mumol and higher are analysed. Individualization of therapeutic-tactical approach with the use of preoperative diagnosis of the level of obstruction of the bile ducts and severity of the state of a patient, and as well their preoperative decompression with the use of endoscopic methods permit to accomplish a number of measures aimed at reduction of the incidence of purulent-necrotic complications and lethality, improve the long-term results of treatment of the patients with obstructive jaundice.
