[Personal experience with salpingoplasty. Apropos of 285 cases].

285 cases of salpingoplasty are reported and studied. Only 172 patients could be followed up recently. The percentage of pregnancies was 27-7, 20 per cent were intra-uterine pregnancies. The percentage of successful pregnancies was 45-93 if only those patients who were seen again were reviewed. The results are best when the operation is carried out in the most conservative and most anatomically restorative fashion. This fine surgery, which must be carried out so delicately and with such detail, which will appeal more and more to modern technicians using micro-surgery, should stay in the hands of specialists because there is no doubt that the level of success rises with the experience of the operator.

[The risk of cardiac arrest during laparoscopy. A study of 50,000 laparoscopies and animal experimentation].

In a French national enquiry into 50,000 laparoscopies it emerges that the number of cardiac arrests works out at 1 in 2,000. The percentage of reversible cardiac arrests was 1 in 2500 and of irreversible cardiac arrests 1.2 in 10,000. 25 cases were studied in great detail, both clinically and physiopathologically. This was thanks to a very full questionnaire most kindly filled up by those who had told us that this type of accident had happened in their practice. The physiopathogenesis of circulatory arrests during laparoscopy is complex. It appears however that among the different potentiating factors are changes in haemodynamics and biological changes that give rise to the greatest risks. Experimental work carried out with a long-tailed baboon was performed by the authors with the idea on the one hand of confirming that haemodynamic and biological troubles resulting from the pneumoperitoneum were important and on the other hand of analysing the changes in detail and of working out prophylactic principles for the anaesthetist and the laparoscopist.
