[Biological and synthetic prostheses in gynecologic microsurgery]. / Le protesi biologiche e sintetiche in microchirurgia ginecologica.

Biological prostheses of human umbilical vein and synthetic prostheses of ePTFE were comparatively studied in the microsurgical anastomosis of the uterine horns in twenty rats. Patency rate after 30 days was 60% for umbilical vein and 75% for the ePTFE prostheses. Gross and histological examination of umbilical vein graft specimens showed minimal alteration with a smooth intimal surface. On the contrary tissue covering the inner surface from the adjacent ends of the uterine horns was noted in ePTFE prostheses.

[Experimental study of different techniques for partial resection of the ovary]. / Studio sperimentale di differenti tecniche di resezione parziale dell' ovaio.

The effects of leaving the ovarian cortex open after wedge resection were studied in a rabbit model. Twelve animals were operated: in one ovary the ovarian cortex was reattached with microsurgical sutures and in the contralateral it was left to heal by secondary intention. No significant differences were observed in adhesion formation and tissue reactivity between the two techniques. These data support the hypothesis that reattachment of the ovarian cortex is not necessary after conservative ovarian surgery and these findings could be useful in the laparoscopic treatment of benign ovarian pathology.
