[Surgery of giant bullae of emphysema in adults].

Over a 20 years period 50 patients with giant emphysematous bullae (bilateral in 20 cases) were operated upon. Fifteen had been exposed to an occupational risk (coal mining, steel milling, chemicals); all were, or had been, tobacco smokers; 11 were in acute respiratory distress at the time of surgery. Respiratory function tests showed mixed restrictive and obstructive impairment. Ten patients had chronic cor pulmonale. There were 8 post-operative deaths, 4 of them with right-sided heart failure. Mortality was highest in patients with bilateral lesions and in emergency situations. Late complications involved the lungs in 10 cases and the heart in 2 cases. The results of pre- and post-operative lung function tests could be compared in 13 patients.

[Gastroesophageal reflux. Anatomical, physiological and surgical aspects. Apropos of 61 consecutive cases of peptic esophagitis surgically treated with the same procedure].

Based on a literature review and a personal series of cases treated, it is considered that gastroesophageal reflux results mainly from a mechanical process. The importance of the gastric musculature is emphasized, particularly the oblique fibers which form a thick belt encircling the esophagogastric function. Reflux is assumed to be almost exclusively due to loss of fixation of the point of attachment of this belt which, because of its particular texture, allows gastric dilatation to be propagated to the esophagogastric junction. The principal cause is the angular movement of the mobilized cardia. The same result is observed after iatrogenic destruction of this so-called muscular belt. Ulcerated reflux esophagitis is considered to be a serious disease comparable to duodenal ulcer, and the operative technique used aims both at reducing gastric acidity (vagotomy) and the construction of an anti-reflux assembly based on Hill's method. Results of the application of these principles in 61 consecutive cases are discussed.

[Intrathoracic chemodectomas. A report on four observations (author's transl)].

Intrathoracic chemodectomas are extremely rare tumours, the number, published up to the present time being less than 50. We wish to report here four personal cases, all resected. The diagnosis was never made before surgery but solely by histopathology. The course was benign in two cases and malignant with slow progression in one case and malignant with rapid progression in the other. On the basis of these four cases, a general review is undertaken of this particular site on the basis of publications in the literature.
