[Cerebral metastases manifesting as bronchopulmonary carcinoma (small-cell cancers excluded). The surgeon's viewpoint].

Within the last 20 years, 16 patients have undergone surgery for solitary intracerebral tumours revealing asymptomatic broncho-pulmonary cancer for which they all underwent subsequent operations without operative mortality or morbidity. One patient who was operated upon at the age of 39 is still alive without recurrence 11 years after removal of an intracranial metastasis, and 9 years after successful lobectomy for a mixed bronchopulmonary carcinoma (adenocarcinoma and a squamous cell carcinoma). This patient received no adjuvant treatment. The other 15 patients had survivals varying from 2 to 18 months. The treatment of bronchial carcinoma and its metastases is a complex problem, in particular as regards the indication for surgery, which for most patients is the only means of improving survival and, in exceptional cases, securing prolonged remission.

[Ischemic damage of the distal digestive tract after angioplastic surgery of the infrarenal aorta for aneurysm or aorto-ilio-femoral obstruction (Leriche's syndrome)].

Ischemic damage to the distal part of the digestive tract is rare after elective surgery for aorto-ilio-femoral aneurysm or Leriche's syndrome, but is frequent after resection of a ruptured aneurysm in older patients, who are operated on in a state of hypovolemic shock. During the past 20 years, we observed 25 ischemic manifestations of the distal digestive tract from a total of 916 surgical patients. Of these patients, 180 had an aneurysm which was ruptured in 73 cases, and 736 underwent surgery for an aorto-ilio-femoral stenosis or obstruction. Transient ischemia, which affects in a majority of cases the left colon, usually heals without leaving any sequellae. Irreversible damage which progresses to gangrenous necrosis of all or part of the colon holds an important share of the postoperative death rate. To avoid these accidents, it is important to reestablish in a correct manner all vascular axes, to avoid states of hypovolemic shock which, through a "small output syndrome", result in vascular thromboses, and finally to monitor aneurysmal patients in intensive care units so as to rapidly detect and treat ischemic complications to the digestive tract.

[Aneurysms of the abdominal aorta].

Over the last 20 years, 170 patients have been operated on for infrarenal aortic aneurysm. Ninety-six were operated on electively. Seventy-four underwent emergency surgery, of whom 62 had a ruptured aneurysm. In elective surgery mortality was low, falling in recent years from 10.5 to 2.7%, due to systematic postoperative resuscitation in intensive care and growing experience in the field of aneurysm surgery. Emergency surgery for ruptured aneurysms is associated with a mortality of up to 56%, which is even higher for patients operated on at the hypovolemic shock stage. Presently, the most important aspect of abdominal aortic surgery is lowering of the number of ruptured aneurysms, since at this stage aneurysm resection is inevitably associated with high mortality. Improvement of prognosis requires early diagnosis, effective resuscitation in the intensive care unit, knowledge and prevention of postoperative complications, and teamwork between surgeons, physicians, anesthesiologists, hematologists and nephrologists.

[Transthoracic approach to dorsal disc hernias].

Three cases of thoracic disc protrusions, treated by the transthoracic surgical approach, are reported. The signs and symptoms of the patients were not essentially different from findings encountered in other types of space-occupying thoracic intra-spinal lesions. The diagnosis by high resolution computed axial tomography provides more information and may eliminate future use of myelography. In their median localisation, the thoracic disc protrusions are equally accessible by either a right or a left transthoracic approach. Yet, the right lateral approach was preferred because of the overlapping aorta on the left. If, for some reason, a left lateral approach is considered, the level of entry of Adamkiewicz artery should be identified by preoperative spinal angiography. The postoperative results are excellent in all three cases as opposed to a fourth operated by laminectomy.

[Oral contraceptives and liver tumors].

That oral contraceptives have repercussions on the liver and bile ducts can no longer be denied. The role of oral contraceptives in inducing malignant or benign hepatic tumours is not universally admitted. From 1968 to 1979 the authors enumerated 29 hepatic tumours (18 benign, 11 malignant). In 13 cases the benign tumour was associated with the use of oral contraceptives and the tumour was diagnosed during or after the course of contraceptives. The signs and symptoms leading to the discovery of the benign hepatic tumour were an abdominal mass or enlarged liver in 3 cases and intraabdominal hemorrhage in one. In 9 cases the tumour was discovered at surgery. The contraceptive used was a preparation containing ethinyl-oestradiol, mestranol and a progesterone. The number of benign hepatic tumours has increased relatively in recent years, and this would seem to coincide with the utilization of oral contraceptives. For the moment definite proof is lacking, as the period during which the authors have studied this problem is still too short.

[Granulomatous tumors of a pseudo-Hodgkin type of the thymus gland (thymus gland lymphogranulosarcomas)].

The group of thymic lymphogranulosarcomas are losing their pathologic individuality as autonomous thymic tumors with particular histological and special evolutive characters. Experience shows that a good number of alleged "pseudo-hodgkinian thymomas" have evoluted in the hodgkinian mode. From a total of 56 apparently autonomous thymic tumors operated on in the Department of Surgery A at this hospital, 9 thymic lymphogranulosarcomas have been identified. Our observations confirm that "pseudo-hodgkinian" tumors of the thymic lodge are rather Hodgkin's disease or a primitive-ganglion Hodgkin's disease localized in the thymic lodge. In practice, the discovery of granulomatous tissue in a thymic lodge tumor, even in the absence of typical Sternberg cells, requires a search for other localizations to determine the evolutive stage of the disease. Experience shows that partial or total surgical excision, followed by combined chemotherapy, exploratory laparotomy and radiotherapy, offer the best chances of long term survival at present.

[Intralobal pulmonary sequestration and tuberculosis superinfection].

Among 16 pulmonary sequestrations observed in 23 years, 3 were associated with pulmonary tuberculosis. A detailed report is given on a 37-year-old man who was found by serendipity to have a right lower sequestration after 6 years treatment for tuberculosis; middle and upper lobe function had already been lost. Two and half years after pneumonectomy, the patient is in good health. Discussion centers on the diagnosis and potential complications of pulmonary sequestrations.
