T. Boryssowicz. Stale rozszerzenie ujscia zewnetrirnego macicy, zapomoca przewiazania bocznych scian dolnego odcinka czesc pochwowej (Medycyna, 1893, no. 9). Persistent expansion of the external uterine opening by ligation of the lateral walls of the lower branch of the vaginal part (Dilatatio ostii externi uteri ope ligaturae)

Persistent expansion of the canal of the uterine cervix in order to cure infertility or painful months began to be applied even from the beginning of the past century. But all the methods of discisionis portionis vaginalis proposed so far leave a lot to be desired and, according to Schroeder, produce either too little or excessive enlargement of the external opening, always disfiguring the vaginal part.
