[Therapy of lithiasis of the main biliary passages].

On the basis of a total of 3692 surgical interventions performed on biliary pathways, of which 431 (11,6%) for lithiasis of the hepato-choledocus, the authors discuss the indications, the limitations and the results of surgical treatment in this affection. The postoperative death rate was 10,3% in the first 10 years of the period during which these interventions have been performed and decreased to 5,5% in the last 10 years. The late results were good and very good in 85% of the cases. In view of the continuing decrease in the death rate after surgery, and for improving late results, the authors stress the necessity of early interventions in the lithiasis of main biliary pathways. They also stress the correct exploration of the hepato-choledocus in the course of all surgical intervention upon the biliary pathways.

[Treatment of hernias and eventrations with alloplastic material (Mersilene type mesh)].

Between 1973 and 1979 the authors have performed 126 interventions, as follows: 27 hernias (18 of the inguinal type and 9 umbilical ones), and 99 eventration. They used alloplastic materials for consolidation or substitution of the musculo-aponevrotic wall of mediocre quality. In practice the "Mersilene" alloplastic material was used, made of dacron fibers, which provides a series of advantages: good tolerance, efficient sterilisation without undergoing degradation, possibility for use in reparation of large wall defects, high resistance. The net was applied for consolidation purposes in most of the cases (111 in all), and was placed either above the aponevrosis, or pre- or intra-peritoneally. In 15 patients it was used for substitution, when eventration resulted in a large muscular-aponevrotic defect. The results were very good, and a single recidive was noted, as well as two partial rejections, that did not however result in recidives.

The echo Doppler study of mitral and aortic prostheses function.

Doppler echography is now the most accurate noninvasive method for studying valvular prostheses, but the values considered to prove a normal function are still controversial. We studied by echo Doppler 95 valvular mechanical (M) and biological (B) prostheses, in mitral (Mi) and aortic (Ao) position in patients without clinical signs of prosthetic dysfunction. The data obtained for Ao prostheses (maximal transprosthetic gradient (MxG): M-20.47 mmHg, B-7.95 mmHg; mean transprosthetic gradient (MG): M-7.98 mmHg, B-3.9 mmHg) are in agreement or even better than literature data. For Mi prostheses the prosthetic area (PA) and pressure half time (PHT) values are in normal limits but the MG (M-5.087 mmHg, B-5.9 mmHg) is slightly superior to the data reported in the literature. Proving the value of echo Doppler for the study of valvular prostheses our results suggest to adopt larger limits of normality for mitral prostheses. They also sustain the necessity of a first Doppler examination before the patient is discharged from the hospital after valvular replacement.
