title: Nd:YAG laser endometrial ablation: histological aspects of uterine healing.
abstract: Laser ablation of the endometrium performed under hysteroscopic control is a novel procedure for the conservative management of menorrhagia in cases of dysfunctional uterine bleeding. The effect this has on the uterine cavity and the mechanism of reepithelialisation and endometrial regeneration have been examined by means of histological examination of endometrial biopsies and four hysterectomy specimens obtained for various indications at varying time intervals after laser endometrial ablation. During the first 3 months, fragments of necrotic and granulation tissue are found surrounded by a limited polymorph response. By 3 months, the uterine cavity appears to be completely reepithelialised. After 6 months, areas of normal-appearing endometrium may persist, but in other areas there is an attenuated cuboidal surface epithelium closely applied, to the underlying myometrium. Stromal fibrosis reminiscent of Asherman syndrome is also apparent.
