Anaesthetic management of tracheal surgery using the neodymium-yttrium-aluminium-garnet laser.

A new technique for the management of tracheal or bronchial lesions (tumours or stenosis) using the NdYAG laser and bronchoscopy, was used in 55 patients without complications. The anesthetic problems are discussed. In some circumstances the procedure may be performed using sedation and topical anaesthesia. In most, general anaesthesia was used, controlled ventilation being achieved through the bronchoscope using a modification of the Sander's injector with mixture of 50% nitrogen and oxygen to avoid the risk of fire.

[Indications and results of the use of YAG laser in bronchology. Apropos of 89 cases].

A YAG Laser beam adapted to bronchial endoscopy was used in 89 patients (6 bronchial tumors, 7 tumors of reduced malignancy, 37 tracheo-bronchial cancers, 39 iatrogenic lesions including 24 stenosis and 15 granulomas). Curative indications (isolated bronchial tumors, diaphragm-like stenosis) were rare. The authors stress the interest of palliative indications: inoperable tracheal stenosis and certain forms of tracheobronchial cancers. The criteria of lesions attainable by the Laser are specified.

[Modalities and interest of preoperative staging in primary lung cancer (author's transl)].

The study of the extension of primitive lung cancer involves, on one hand, the determination of the locoregional extension concerning the tumator and adenopathies, and on the other hand, the determination of the metastatic extension. A careful clinical examination determines the need for complementary examinations providing decisive information for or against interventions. Systematic lung endoscopy should consist of staged biopsies. Mediastinoscopy estimates the locoregional extension in a more satisfactory manner than angiography or lung scintigraphies. The search for bone or cerebral metastasis is often negative in the absence of clinical symptomology in spite of the recent contribution of tomodensitometry. The detection of abdominal metastasis by biological examination, scintigraphies or contrast X-rays is liable to interpretational errors in one-third of the cases. It is for this reason that we preconize laparotomy before lung exeresis. In our series, among 175 laparotomies, 35 revealed abdominal metastasis whose discovery enables us to avoid useless, if not harmful, thoracic surgery.

[Primary sarcoma of the pulmonary artery of the hemangioendotheliosarcoma type].

A case of primary sarcoma of the pulmonary artery presenting with the symptomatology of a bronchopulmonary tumour is studied in comparison with those reported up to the present in the literature. The tumour, examined in the pneumonectomy specimen, appeared to be inserted into the trunk of the left pulmonary artery with unusual propagation in the distal arteries. It had also spread into the neighbouring bronchial lumina. Histologically, the appearance was, rarely, that of a haemangioendotheliosarcoma. The histogenesis of these neoplasms is briefly discussed.

[Surgery for carcinoma of the oesophagus. A plea for precise technique and pleuro-mediastinal drainage (author's transl)].

During surgery for carcinoma of the oesophagus, the authors emphasise the need for selective intubation using a Carlens tube, of avoiding damage to the diaphragm and the phrenic nerve at all levels, and of draining the hemithorax involved in the operation by three drains: anterior and posterior thoracic and madiastino-abdominal. These precautions reduce post-operative difficulties, justifiy excision surgery for carcinoma of the oesophagus, and to a certain extent make it possible to reduce the contraindications, in particular in the presence of tracheo-bronchial spread. Amongst 107 patients undergoing surgery, in whom there was a risk of respiratory insufficiency in one quarter, surgery (sometimes with extension of the excision: one case in four) was associated with an operative and post-operative mortality of 18%.

[Diagnostic value of closed thorax pericardial biopsy. 20 cases].

Twenty patients with sub-acute and chronic pericarditis under went closed thorax pericardial biopsy. In three cases the examination brought to light a diagnosis of tuberculosis and in one of a tumoural origin. In 16 cases in which the aetiology was that of a non-specific pericarditis, the value of this examination, integrated into the context, is discussed.
