Hysteroscopic tubal sterilization with Essure intratubal devices: a case-control prospective with inert local anesthesia or without anesthesia.

OBJECTIVE

The contraceptive efficacy of hysteroscopic sterilization is well documented. The objective of this study was to compare procedure success, patient tolerance, and procedure time of Essure micro-insert hysteroscopic sterilization with or without anesthesia.

STUDY DESIGN

Between February 2002 and May 2005, one operator performed 140 sterilization procedures in this prospective study: the first 70 were performed using local anesthesia and the following 70 began without administration of anesthesia. Analysis was based on intention-to-treat.

RESULTS

The groups were comparable in their demographic characteristics. Successful bilateral micro-insert placement in the first 70 cases, utilizing paracervical block, was 82.8% and did not differ significantly from the next 70 cases, without anesthesia (91.4%). A similar number of patients in each group received additional anesthesia. Report of procedure pain did not differ significantly between the groups: 87.1% reported moderate or less pain with the paracervical block, compared with 91.4% in the group without anesthesia. Duration of surgery was significantly shorter without anesthesia: 11.2+/-6.3 min vs. 25.0+/-8.0 min (p<0.001).

CONCLUSIONS

Administration of anesthesia does not appear to affect the procedure completion success rate or patient tolerance of this hysteroscopic sterilization procedure.
