[A case of complete absence of the left pericardium coexisting with straight back syndrome].

A case of complete absence of the left pericardium coexisting with straight back syndrome in a 30-year-old female is presented. She had been asymptomatic, but was referred to our hospital because of an abnormal finding on a chest X-ray obtained during a routine physical examination. The posteroanterior view of the chest X-ray showed displacement of the right and left cardiac border to the left and bulging of the left cardiac border. The lateral view showed loss of normal thoracic curvature and also demonstrated the straight back syndrome. Echocardiography showed paradoxical movement of the ventricle septum, hyperkinetic movement of the free wall of the left ventricle and enlargement of the right ventricle. Computed tomography and magnetic resonance imaging with an artificial pneumomediastinum clearly showed rotation of the heart into the left hemithorax, prominence of the pulmonary trunk and pneumopericardium. Hence the diagnosis of the complete absence of the left pericardium coexisting with straight back syndrome was made. Congenital defect or absence of the pericardium are rarely reported. Only about 120 cases have been described in Japan. Only a few cases have been diagnosed antemortem. Most of them were found by chance during operations or on installation of an artificial pneumothorax. We suggest that an artificial pneumomediastinum as well as a pneumothorax is useful for the diagnosis of the absence of the pericardium. This is the first reported case of a complete absence of the left pericardium coexisting with straight back syndrome.

Tumor invasion of the chest wall and mediastinum in lung cancer: evaluation with pneumothorax CT.

For preoperative evaluation of chest wall and mediastinal invasion by lung cancer, computed tomography (CT), combined with artificial pneumothorax (pneumothorax CT), was performed in 43 patients with lung cancer in whom conventional CT scans showed that the mass was contiguous to the chest wall (n = 30) and/or mediastinum (n = 25) but without evidence of definite tumor invasion. Invasion was diagnosed on the basis of whether an air space existed between the mass and the adjacent structures. In three patients pneumothorax was not produced. After the procedure, four patients developed symptomatic pneumothorax, and one, subcutaneous emphysema. Comparison of diagnoses based on findings at pneumothorax CT, surgery, and pathologic examination showed that pneumothorax CT is 100% accurate for chest wall invasion and 76% accurate for mediastinal invasion. The authors conclude that this procedure is helpful in accurate evaluation of the T criterion in lung cancer, especially for patients in whom findings at conventional CT suggest tumor invasion of the chest wall and mediastinum.

The history of thoracoscopic surgery.

The necessity for thoracoscopy became apparent with the adhesions that limited the success of Forlanini's introduction in 1882 of artificial pneumothorax in the treatment of pulmonary tuberculosis. The first thoracoscopy, using a modified cystoscope, was performed by H. C. Jacobaeus, a professor of medicine, not surgery, in Stockholm, publishing in 1910. Thoracoscopy and division of adhesions (intrapleural pneumonolysis) then spread all over the world, with reports of series of 1,000 or more cases in spite of a significant incidence of complications. Its use declined rapidly after the introduction of streptomycin in 1945, becoming then confined to relatively minor diagnostic procedures except in a few European centers. The advent of video-assisted thoracoscopes and the development of ancillary instruments has allowed a new explosion of thoracoscopic surgery. Surgeons, in whose hands the procedure now rests, should nevertheless be aware of the five unacceptable thoracoscopic disasters--wrong side, kebab lung, "clotted hemothorax," artificial lunchothorax, and aorto-pleuro-cutaneous fistula.

Samuel Robinson, pioneer thoracic surgeon (1875-1947).

Sam Robinson was born in Augusta, ME, in 1875. A graduate of Harvard Medical School, and of the Massachusetts General Hospital (MGH), he worked in the laboratory of Walter Cannon. While a junior at MGH he spent four months abroad with Ferdinand Sauerbruch. He returned to Boston and remained there until 1912, performing his first successful lobectomy for bronchiectasis in 1909. He made important contributions to the management of pneumothorax during operation, notably Sam Robinson's box. In 1912 he moved to Clifton Springs, NY. From 1915 to 1917 he was the first Chief of Thoracic Surgery at the Mayo Clinic. Illness, probably bronchiectasis, led him to abandon academic thoracic surgery in 1918 and retire to Santa Barbara, CA, where he practiced general surgery until 1947. He was President of the Association for Thoracic Surgery in 1922. In addition to the use of positive pressure and early resections, his contributions include artificial pneumothorax for tuberculosis and management of acute and chronic empyema. His colorful writings provide a vivid picture of the early days of our specialty.
