[Hysteroscopic sterilization using Ovabloc].
The authors give an account on 29 sterilizations made by the hysteroscopic route, using the preparation OVABLOC. It is a reversible block of the oviducts by occlusive material. Under hysteroscopic control into the inner orifice of the oviduct by means of a special injecting device under pressure a two-component mixture of silicone and a catalyst is instilled which causes within 5 min. hardening of the mass and the formation of an elastic relief filling of the entire oviduct. In 25 of the women (86.2%) the procedure was accomplished without complication, in the 3 (10.3%) the procedure failed on account of technical difficulties and in one case (3.5%) during hysteroscopy the uterine wall was perforated. On X-ray check-up after three months of 25 successfully operated women in 24 the position of the tubal occlusion was unaltered (the material is due to dispersed silver particles contrasting on X-ray); in one case it was loosened. The advantages of the method are that it is sparing, well tolerated and easily reversible, the disadvantage is that it is relatively laborious and expensive.
