[Abdominal echotomography in a pneumology department].

In the last years, echotomography has become an essential element in the diagnosis of a number of diseases. In pleuro-pulmonary pathology, echotomography is also valuable for diagnosing pleural diseases and in some pathological conditions affecting at the same time thorax and abdomen. Echotomography of the abdomen is advised in a number of cases. The diaphragm and regions above and below it should be tested when there are deformations of the cupolae and radiological images in the pulmonary bases. Liver is investigated to trace any possible hepatic localization of broncho-pulmonary cancers or any chest hydatidosis. Echographic investigation of pancreas is advisable when a tumour of glandular origin is diagnosed. For patients with mesotheliomas, it should be associated to a retro-peritoneal investigation.

[Echotomography of the liver with three-dimensional representation of the organ].

Three-dimensional representation facilitates the reading of ultrasonic seriographs of the liver. It uses a conducing wire to provide a correspondence between the xipho-umbilical line and the information collected on the seriographic polaroids. Proceeding from image to image, a more thorough interpretation is possible. This analytical study provides a synthetic representation of the organ. When present lesions are seen on these diagrams and their location and dimensions clearly defined. A precise indication of the height, breadth and thickness of the organ is given, which makes it possible to obtain an accurate approximation of the hepatic volume, taking the morphotype into consideration.

[Value of echotomography in pleuro-pulmonary pathology].

Echotomography based on the use of ultrasound as a diagnostic tool, little used until now in pleuropulmonary pathology, seems interesting and valuable and diserves to be counted amongst the various paraclinical examinations. Out of a hundred patients, we obtained the following results: -- 91.7% success in the needle biopsies done after echotomography. -- 84.4% success in exploring peripheral pulmonary tumor. -- 100% success in plotting: pleural thickening in which figures obtained with ultrasounds are very close to those obtained directly by needle. Echotomography in pleuropulmonary pathology has the following indications: -- for pleura effusions, pleural thickening and tumors; -- for pulmonary parenchyma: evolving or stable, solid or liquid masses, that are close enough to the thoracic wall; -- for mediastinum: lesions localized in the anterior mediastinum and related to the sternocostal wall. In all these cases echotomography brings valuable complementary information, sometimes allowing the location of fibrohyalin pleural plaques of asbestosis invisible on X rays. By combining a wider experience and the perfectioning of the equipment, this method could become a common practice in pleural pathology and thoracic oncology.

Staging of rectal cancer: a prospective study of digital examination and endosonography before and after preoperative radiotherapy.

Between January 1988 and January 1992, 34 patients with rectal cancer were evaluated both by clinical examination and endosonography before and after pre-operative radiotherapy. Two criteria were correlated with histologic findings: confinement to the rectal wall or spread beyond, the presence of mesorectal lymph node involvement. The 32 patients who underwent endosonography before radiotherapy were staged as: uT2: 4, uT3: 26, uT4: 2 cases. Fifteen days after irradiation, endosonography showed tumour regression in all cases; uT stage was different in 15 patients, uN stage in 4 cases. Comparison of the pre-operative local invasion beyond the rectal wall with postoperative histopathy revealed a correlation with: digital examination after radiotherapy in 20 of the 31 patients with palpable tumours; endosonography before irradiation in 18 of the 32 staged tumours; endosonography after irradiation in 25 of the 32 staged tumours. The presence of mesorectal lymph node involvement determined by histologic examination was correlated with the results of endosonography after radiotherapy for 22 of the 32 staged tumours. Endosonography provides a good assessment of the tumour stage before irradiation. Since radiotherapy alters endosonographic staging of rectal cancer, this staging should be included in survival studies.
