Out of 1,300 cases of gynecologic laparoscopic procedures reviewed, three incidences of preperitoneal emphysema and several incidences of subcutaneous emphysema were noted. There were a few significant differences in the diagnosis and management of these two types of emphysema. In the medical literature reviewed by the author, preperitoneal emphysema has not been discussed while subcutaneous emphysema has received quite a lot of attention. Preperitoneal emphysema is defined as a collection of air or other gas which occurs in the tissue spaces between the abdominal fascia and the ventral peritoneum.

A unilateral dilatation of the parotid duct of Stenon (parotis emphysema, pneumatocele) was observed in a 73-year-old patient. The possible course of development - inflammatory or other known factors excluded - for example by means of leucoceratosis nicotina palati are discussed.

A clinicopathological study of 21 patients who died as a result of chronic airways obstruction was carried out. Thirteen patients had been in right ventricular failure for at least one year before death and the other eight patients did not have right ventricular failure. The patients with long-standing right ventricular failure died at a younger age, on average, than those without failure. There were no significant quantitative differences between the two groups in the length of history of chest disease, blood gas estimations, respiratory function tests or degree of polycythaemia. The group with right ventricular failure had significantly larger mean right and left ventricular weights than the group without failure, but there were no significant differences in amounts of emphysema, size of bronchial mucous glands, proportion of small airways lumen in the lung or number of thick-walled peripheral lung vessels between the two groups. The findings did not support the division of this series of patients, with fatal chronic airways obstruction, into two distinct groups broadly defined as 'emphysematous' and 'bronchitic', either clinically or pathologically. A history of right ventricular failure correlated well with the finding of right ventricular hypertrophy at necropsy. Electrocardiographic evidence of right ventricular hypertrophy was found to correspond with the size of the right ventricle at necropsy in 66% of cases. The radiographic diagnosis of emphysema proved an accurate assessment when compared to the necropsy findings, and radiographic estimations of right ventricular enlargement were accurate in 65% of cases. Histological evidence of acute bronchitis was present in 20 of the 21 patients (95%), and five patients showed histological evidence of minor pulmonary thromboembolism. Ten patients in the series showed an increase in the weight of the left ventricular as well as the right ventricle.

The authors make an analysis of 455 cases of spontaneous pneumothorax hospitalized and treated in the Clinic for Thoracic Surgery from Bucharest between 1952 and 1974. The therapeutic attitude recommended in such cases is the aspiration drainage through minimal pleurotomy (aspiration being carried out in relation with the parenchymal aerial losses). Introduction through the drainage tube of irritating substances will enhance pleural symphisis. The drainage will be maintained for 7--8 days. In the recidivating pneumothorax, or in cases where recovery is not achieved by aspiration drainage, thoracotomy becomes necessary for performing total pleurectomy and atypical resection of emphysema bubbles from the pulmonary cortical, since these are at the origin of the aerorrhagies (the Coman procedure). With the aid of these surgical techniques very good results have been obtained in all cases of spontaneous pneumothorax.

The accuracy of interobserver variability of roentgenographic analysis for cardiac size in patients dying with chronic bronchitis and pulmonary emphysema were correlated with pathologic data derived from special studies. Three trained observers were able to accurately and consistently diagnose chronic bronchitis and pulmonary emphysema and to detect cardiomegaly on the chest x-ray film. The best criteria for chronic bronchitis and pulmonary emphysema were those of overinflation; however, none of the roentgenographic criteria usually suggested for the specific diagnosis of right ventricular or left ventricular hypertrophy were found to be reliable. The inaccuracy and interobserver variability in the detection of enlargement of specific chambers make it evident that the usual criteria are not valid and that roentgenographic appraisal of cardiac size in these patients in limited to findings of normalcy or cardiomegaly.

Congenital lobar emphysema is reported occurring in a 10 day old, low birth weight infant. Following resection, gross examination of the affected lobe revealed collapsed but unobstructed bronchi, suggesting a cartilaginous defect. The specimen was insufflated with formalin and the bronchial tree dissected out. Histological study including comparison with a normal pulmonary lobe, confirms that abnormalities of cartilage may be important in the pathogenesis of congenital lobar emphysema.

As previously reported, most complications of laparoscopy occur during the induction of pneumoperitoneum. In addition to the known complications of emphysema, embolism, and pneumocolon, the insufflating needle may occasionally cause bleeding by entering inadvertently into a vessel which may in rare situations be a mesenteric artery. Luckily, this complication is rare enough not to necessitate typing, cross-matching, and preparation of blood for every laparoscopic procedure. Injury to the iliac mesentery, with mesenteric artery perforation and a resulting hematoma, occurred during laparoscopy for tubal sterilization. This report describes the operative finding of a Meckel's cord attaching the ileum to the umbilicus, leading to this unusual and serious complication necessitating an immediate laparotomy and ileal resection.

Radiology is the basic factor in diagnosis of emphysema. Further differentiation is possible by assessment of the concomitant cardio-vascular changes. By these means, the type of emphysema (accompanying emphysema in chronic bronchitis, or primary emphysema) can be established.

The cardiovascular and lung lesions in 23 centenarians (7 males and 16 females) were examined pathologically. The heart showed varied degrees of hypertrophy, and myocardial fibrosis was present in 15 of the 23 patients. Coronary arteriosclerosis was noted coincidentally. In addition to these findings, amyloid deposition was seen in the hearts of 8 patients. Generalized atherosclerosis of the arterial tree was severe to moderate in all cases. Bronchopneumonia was present in 15 of the 23 patients, and fresh or old thromboembolism in 8. There was a tendency toward emphysema and chronic bronchitis in the structure of the lung. The frequent occurrence of myocardial fibrosis and bronchopneumonia was characteristic in the series. It was significant that cardiac amyloid deposition was noted in these cases.

Left ventricular function was evaluated prospectively during 1 year in a controlled clinical study of 73 patients with chronic obstructive lung disease. The control group comprised 68 patients matched for age and sex and with no evidence of airways obstruction. Left ventricular hypertrophy was found in 52% and systemic hypertension in 58% of patients in the study group compared with 6% and 15% respectively in the controls. Left ventricular hypertrophy was diagnosed in 70% of patients with chronic bronchitis and in 19% of those with chronic emphysema. Systemic hypertension was observed in 45% of the bronchitic type patients and in 81% of those with emphysema. The incidence of myocardial infarction in the study group was not lower than in the controls. The high frequency of left ventricular hypertrophy in patients with chronic obstructive lung disease can probably be related to a similar high frequency of systemic hypertension. Hypertension per se does not explain left ventricular hypertrophy in all patients with chronic bronchitis, but hypoxemia and acidosis seem to be of pathogenetic importance in these cases.
