Experimental hydrosalpinx and salpingostomy in rabbits.

In 137 oviducts of New Zealand white rabbits different kinds of occlusion techniques were tested to induce hydrosalpinges. In 99 oviducts ligatured or clipped both at the fimbrial end and at the ampullary-isthmic junction 67 hydrosalpinges were achieved, whilst in 34 oviducts ligatured or clipped only at the fimbrial end one hydrosalpinx occurred. Most severe histological changes were seen after double clipping. Ligation of the blood vessels to and from the ampulla of 4 oviducts caused no hydrosalpinx formation. After cuff salpingostomy a higher number of patent oviducts was found than after double-loop salpingostomy.
