[1318 nm YAG-ND laser in surgery of lung metastases].

YAG laser with 1318 nm wave was used in the treatment of 23 patients with peripheral lesions of the lungs, 7 of them had multiple lung metastases. Advantage of YAG laser over electric knife was demonstrated. In diagnosis of lung metastases it is necessary to consider not only results of computed tomography but also ones of intraoperative palpation that requires a wide surgical approach for hand manipulation in the pleural cavity. This method permits one to detect more metastases. Lateral thoracotomy with or without rib resection creates optimal conditions for use of YAG laser in surgery of multiple lung metastases.

[Ultrasonic diagnosis of focal damages in thoracoscopic operations].

5-year experience of developed in PAMS A.V. Vishnevsky Institute of Surgery RAMS ultrasonic examination (USE) of the lung in thoracoscopic operations for focal lung lesions (FLL) is presented. Pilot experience of ultrasonic topical and differential diagnosis of FII opens a new page in diagnosis of respiratory diseases. Over 5 years 74 USE of FLL were performed. FLL were found in 91% cases. Detailed topical diagnosis of allows to design the lung resection with the best functional result. In postoperative X-ray examination neither atelectases nor zones of stable hypoventilation were detected. Normal echographic picture of lung tissue and echosemiotics of different focal lesions are descubed. The experience of diagnosis by echographic signs of FLL shows teasibility of differentiation of hamartomas from tuberculomas and focal metastatic lesions. The payential of differential diagnosis is illustrated. Differential diagnosis supported enucleation in superficial hamartomas and resection in suspected malignant tumor or tuberculosis. Use of intraoperative USE in the majority of cases of focal lesions located both in depth of lung tissue and subpleurally warrants the success of operation in thoracoscopic variant.

[Videothoracoscopy in diagnosis and treatment of small peripheral pulmonary masses].

This study was devoted to examination of efficacy of modern methods of diagnosis and surgical treatment of patients with small peripheral pulmonary masses (SPPM) with the use of videothoracoscopy. The results of examination and treatment of 126 patients with SPPM (80 patients underwent videothoracoscopy) were analysed. This study demonstrated high-quality of modern complex of clinicoradiological investigations for diagnosis of SPPM. The reliability of the complex is 91%. The necessity of immediate elective operation of the patients with SPPM is shown for verification of the process and adequate surgery. Videothoracoscopic surgery is effective method of treatment in patients with SPPM.

[Ultrasonic study in thoracoscopic operations].

Intraoperative ultrasound diagnosis (IOUSD) was made in several thoracoscopic interventions in 15 patients: diagnostic thoracoscopies (3) in patients with lymphogranulomatosis, carcinoid and peripheral lung cancer, enucleation and atypical resection of the lung (4) in patients with hamartochondromas, in excision of lung cyst (1), in removal of foreign body of the lung (1), in removal of celomic cysts (2) and in ablation of neurofibroma of the mediastinum (1), in atypical resection of the lung and enucleation of tuberculomas (2). Video thoracoscopy in combination with intraoperative ultrasound examination provides possibility for precisional diagnosis of focal disease of the lung and mediastinal organs, including local masses of small sizes, and is rather informative method of diagnosis. IOUSD allows to define the diagnosis more exactly and to determine the extent of pathological process, to prevent complications and locate intraparenchymal masses and foreign bodies in lung tissues, and thus enables to complete operation without thoracotomy.
