Abstract

There are many problems before dinica surgery. which can be solved and part of them is being solved successfully in present time with the use of laser spectroscopy methods. In accordance with it the following general work directions have been determined: investigations of the functional state of intracavital organs. metabolic processes. operative and conservative treatment efficiency: - diagnostics of neopiasms including the malignant tumors of intracavital organs and intravascular formations: - control to the dose of laser irradiation during the laser diagnostics, therapy and surgery. Taking into account these directions the main efforts are concentrated on the solution of the following tasks: determination of microcirculating blood hemoglobin concentration and oxygenation degree in the mucous of stomach bowel tract, trachea bronchial tree and skIn; - determination of oxygen utilization degree by the mucous of i ntracavital organs and defi n ition of tiss ue destruction degree: - diagnostics of intracavital organs malignant new growths early forms and skin cancer on the base of spectra analysis of endogen tumor organic compounds luminescence 'nder 'aser influence: laser spectroscopic control to the completeness of different organs malignant sections ectomy during the surgical operation: - investigation of the influence of laser excitation on reproducing capacity of intracavital organs mucous as in the plan of stimulation as its growing attenuation; laser therapy of stomach and duodenat ulcer; - laser photodynamic therapy of malignant new growths with the use of phototocsic medical preparations with the parallel spectrcscopic control to the dose of irradiation and therapy efficiency; - laser coagulation of malignant and non-malignant neoplasms, stopping of the bleeding; - rechannalisation of occlusive magistral vessels and obturated sections of trachea bronchial tree with the parallel soectroscopic control to the dose of laser rd type of irradiated tissue with the purpose of prevention of bronchial or vascuiar walls perforation and timely influence stopping -spectroscopic express-analyse of blood and peritonitis exudation with the purpose of prevention of sepsis and peritonitis possibie evauatiori after operation.
