Quantitative morphometric and histopathological study in rabbit oviducts after microsurgical treatment.

The histopathological lesions remaining after microsurgical tubal reanastomosis were investigated quantitatively by light microscopy and qualitatively by transmission and scanning electron microscopy. In 23 rabbit oviducts, the influence of the suture material poly-p-dioxanon and polyglactin-910 and post-operative time interval (6 and 12-15 weeks) was evaluated and compared with non-anastomosed contralateral oviducts as well as with those of unoperated controls. Except in the controls, partial deciliation, pathological kinocilia structure, microvilli and cytoplasmic blebs were found in all tissues, demonstrating an almost complete endosalpingeal restoration.
