Sterilization failure with external migration of the ovum

Abstract

METHODS of tubal sterilization have varied widely from occlusion of the uterine ostium to various techniques of ligation (with and without crushing), tubal section, excision, and closure or burial of the fimbriated extremity. Few of them have stood the test of time without some failure. For a number of years we practiced the Walthard (Madlener) method until some failures were encountered. Then, after witnessing the technique used by Norman Miller of Ann Arbor, that of double tubal ligation of short loops without crushing, we tried that over a period of the past five years. We found the method entirely successful until we encountered this case which wesuspected was a failure until proved otherwise at operation, as reported below. We have had, however, one other case of failure with this technique.
