Hysteroscopic procedures in 257 patients.

Two hundred and fifty-seven hysteroscopic examinations were performed on patients who complained primarily of infertility and abnormal uterine bleeding. Organic intrauterine lesions were identified, and correlations were made with preoperative hysterograms and the tissue obtained for pathologic evaluation. The technique proved of special value for the location and resection of intrauterine devices. Failure to observe the cavity adequately and to complete the examination occurred in 20 (8%) of the patients. The most serious complication, uterine perforation, occurred in five instances but did not require additional treatment.
