title: Studies on experimentally induced hydrosalpinges in rabbits--experimental approach for tubo-microsurgery.
abstract: Hydrosalpinx proved macroscopically and microscopically which was quite similar to that observed in the damage human fallopian tube could be induced by ligation of the rabbit fallopian tube. Where ligatures have been placed on two places of the fallopian tube, hydrosalpinx can be induced in 100 percent of cases if ligation is done securely. About 1-2 weeks after ligation, no change of ciliated cells was observed in the mucosal fold in SEM findings, nor was there much change in the external shape of non-ciliated cells even though hydrosalpinx was induced. With the lapse of time after development of hydrosalpinx, however, both of these cells on the surface of the mucosal fold gradually changed to loose their normal shapes. After 15 weeks, ciliated cells all but disappeared to be replaced by large, filled, irregular non-ciliated cells. Accordingly, hydrosalpinx in the early stage can be cured fully by tubal salpingostomy using microsurgery. In the case of hydrosalpinx many hours after ligation, however, end-to-end anastomosis of the normal regions should be performed since no recovery can be expected.
