[Application of contact laser scalpel in thoracic surgery].

The authors have carried out 296 transthoracic and endoscopic YAG-laser operations in various diseases of bronchopulmonary system. Sapphire and quartz applicator-tips were used as a contact scalpel. The procedures of laser operations with the use of the contact mode are described in detail and comparative evaluation of both types of thermal applicator-tips is given. The combination of cutting and coagulation properties of the contact laser scalpel enables its use in various operations on the lung and pleura including thoracoplastic interventions as well as accomplishment of an endoscopic photoresection of endobronchial tumors.

[The use of laser radiation in the treatment of complicated chest trauma].

The results of treatment of 84 sufferers with a complicated thoracic trauma, using irradiation of the YAG-neodymium, argon, helium-neon and arsenide-gallium lasers, are presented. The techniques for the use of lasers for photocoagulation of defects of the lung and thoracic wall through a thoracoscope, endobronchial laser therapy and laser puncture is described. The expediency to use laser irradiation in the complex of treatment of a complicated thoracic trauma is shown.

[The diagnostic and therapeutic potentials of thoracoscopy in thoracic surgery].

Within a decade, the authors performed 484 thoracoscopies in patients with spontaneous pneumothorax, open and closed thoracic trauma, pleuritis, pleural empyema. High diagnostic possibilities of the method permitted to choose a rational therapeutic tactics. In 228 cases, different endothoracic interventions under the guidance of a thoracoscope were performed. With the use of thoracoscopy, diathermocoagulation, laser and ultrasound irradiation were performed, medical glue was introduced. This permitted in most cases to eliminate intrapleural injuries and achieve stable smoothing of a lung.

[Combined laser therapy of diabetic gangrene of the lower limbs].

Results of treatment of 130 patients with diabetic gangrene, whom the lower limb amputation on various levels was conducted, are adduced. In 58 patients the surgical treatment together with combined use of laser was conducted: intravascular irradiation of blood, high-powered laser Application while amputation performance and after it--percutaneous irradiation of amputation stump. Laser use promotes the improvement of immediate results of treatment and decrease of its duration.

[Diagnosis and treatment of complex closed chest injuries].

The results of treatment of 256 patients with complicated closed chest injury are discussed. Multiple fractures of the ribs were found in 178, closed pneumothorax in 127, pneumohemothorax in 71, isolated hemothorax in 55, and rupture of the diaphragm in 3 patients. Most patients received nonoperative treatment, 5 patients (6.1%) needed emergency thoracotomy. Early drainage of the pleural cavity, endoscopic (thoracoscopy, bronchoscopy) methods of treatment, mechanical stabilization of floating rib fractures made it possible to improve the results and reduce the terms of treatment. Two (0.8%) persons died from shock and cardiopulmonary insufficiency.

[The use of the neodymium-YAG laser in thoracic surgery].

The technique of use of a neodymium YAG-laser for surgical treatment of diseases of the lungs and pleura in 25 patients is described. The experience accumulated is indicative of good aero- and hemostatic properties of the laser, which permit to reduce the incidence of postoperative complications.

[Emergency thoracoscopy in the diagnosis and treatment of complicated chest injury ].

Emergency thoracoscopy was undertaken in 111 patients with complicated closed chest trauma and in 67 persons with penetrating knife wounds of the chest. Thoracoscopy in patients with closed chest trauma revealed pneumohemothorax in 53, pneumothorax in 42, and hemothorax in 10 cases, in 4 patients the hemothorax was coagulated. Penetrating injuries were complicated by pneumohemothorax in 30, by pneumothorax in 21, and by hemothorax in 16 cases. From the results of thoracoscopy, emergency thoracotomy was found to be indicated in 11 patients with penetrating chest wounds. Endoscopic electrocoagulation of the wounds of the lung and thoracic wall was conducted in 28 patients with a closed trauma and in 26 persons with penetrating injuries, laser coagulation was performed in 10 cases with closed trauma and in 8 patient with knife wounds, medical glue was applied for occlusion of surface ruptures of the lung in 11 cases. No complications of thoracoscopy occurred. The therapeutic methods of thoracoscopy with the use of high frequency electric current, NIAH-laser radiation are described. It is concluded that the inclusion of thoracoscopy in the complex of therapeutic and diagnostic measures in patients with complicated chest trauma is expedient.

[Use of laser irradiation in the treatment of lung tumors].

Endobronchial laser therapy was employed in the complex of treatment of 90 patients with tumorous pulmonary diseases. An LG-75 helium-neon laser with the output power of 20 mW was used. A pronounced therapeutic effect was noted in 75 patients. Preoperative recanalization of the bronchi was performed in 25 patients. The YAG-laser based plant "Raduga-1" was used as a source of radiation. No complications after the operation were noted. An antineoplastic effect of the high-energy laser radiation was noted.
