[Cavernoscopy in patients with disseminated fibrous-cavernous pulmonary tuberculosis].

A technique of a dynamic cavernoscopy permitting one to conduct diagnostic and therapeutic manipulations for several months has been suggested. The given procedure was conducted in 36 patients with disseminated fibrous-cavernous pulmonary tuberculosis. An important role in defining management tactics belongs to the direct bacteriological and histological examination of the cavern contents.

[Hyalinizing intravascular bronchioloalveolar tumor--a rare form of diffuse lung lesions].

A rare, badly known diffuse pulmonary lesion--multifocal hyalinizing intravascular "bronchiolo-alveolar" tumour in a woman of 22, is described. The lesion was revealed at fluorography, diagnosed by means of mediastinopleuroscopy, in lung biopsy; there were no clinical manifestations. A hyalinized compact and branching node, poor in cells, intruding at the periphery into the alveolar septa in the form of micropolyps was found histologically.

[Parasternal mediastinopleuroscopy in the diagnosis of malignant neoplasms of the anterior mediastinum].

The authors suggest a clinical procedure of parasternal mediastinopleuroscopy which assures intercostal examination, instrumental palpation and biopsy of neoplasms of the anterior mediastinum without causing considerable trauma. The procedure makes it possible to assess operability and to determine optimal access for surgical removal of tumor. The procedure was used in clinic in 35 cases; in 23 of them, intervention was limited to biopsy, while 12 cases underwent radical surgery.

[Method of extensive mediastinoscopy in lung cancer].

The technic of extensive mediastinoscopy is described, which enables visualization of anatomical structures of the mediastinum and lung hilus inaccessible for an examination while using mediastinoscopy after the Carlens technic. An experience with the extensive mediastinoscopy performed in 116 lung cancer patients is reported. This kind of investigation does not increase the incidence of complications as compared with the Carlens mediastinoscopy.

[Indications for mediastinoscopy in lung cancer].

An experience with 371 mediastinoscopies in lung cancer patients is analysed. The enlargement of intrathoracic lymph nodes revealed roentgenologically or bronchoscopically is considered by the authors to be the basic indication to mediastinoscopy. Among 270 such patients the positive result of mediastinoscopy was noted in 128 (47.
