Study to Assess Outcomes in Women Undergoing Either Hysteroscopic Sterilization (Essure®) or Laparoscopic Tubal Sterilization

Proportion of Subjects Reporting AEs of Chronic Lower Abdominal and/or Pelvic Pain After Insertion of Essure System or After Laparoscopic Tubal Sterilization

The proportion of subjects reporting AEs of chronic lower abdominal and / or pelvic pain after insertion of Essure System compared to the proportion of subjects reporting AEs of chronic lower abdominal and / or pelvic pain after laparoscopic tubal sterilization. Statistical analyses were exploratory and descriptive in nature and no confirmatory hypothesis testing was intended to be performed; p-values were to be interpreted as a metric for uncertainty (note: no analysis included in this final analysis provides p-values). Therefore, no adjustment for multiplicity was necessary. All endpoints and variables were analyzed by descriptive statistical methods.

Time frame: Up to 60 months

Bleeding: The Proportion of Subjects Reporting AEs of Abnormal Uterine Bleeding (AUB) After Insertion of Essure System Compared to the Proportion of Subjects Reporting AEs of AUB After Laparoscopic Tubal Sterilization

Incidence of new onset or worsening abnormal bleeding events was based on AE reporting. If a potential bleeding AE was reported at a scheduled visit or if the subject spontaneously reports such an event to the site at some other time, the event was to be evaluated per standard AE assessment. If during the course of a scheduled PRO administration the subject indicated that she experienced abnormal bleeding that reached a preset threshold on the questionnaire, the investigator was alerted and instructed to investigate this finding in order to determine whether or not an AE occurred.

Time frame: Up to 60 months

Proportion of Subjects With Reported Allergic/Hypersensitivity Reactions

For potential allergic/hypersensitivity reactions, investigators were instructed that an evaluation was to be performed in subjects who presented with symptoms that could have possibly been related to an inflammatory reaction. After the evaluation of the subject was complete, regardless of the investigator's assessment as to whether or not a hypersensitivity/allergic reaction had occurred, all information was to be forwarded to the Adjudication Committee in a blinded fashion. Final determination of whether or not a hypersensitivity/allergic event had occurred was based on the determination of this committee.
