Endometrial reconstruction after hysteroscopic incisional metroplasty.

Endometrial reconstruction after hysteroscopic metroplasty of a septate uterus was studied by light microscopy and scanning electron microscopy when the uterus was removed 13 days after metroplasty for a histologic diagnosis of leiomyosarcoma. We observed a retraction of the margins of the incised septum, which could prevent the formation of intrauterine adhesions. Reepithelialization of the cut surface seemed to proceed both centripetally, by proliferation of the surrounding normal endometrium, and centrifugally from the bottom of the glands present at the base of the septum.
