title: [Definitive contraception with Essure device: Single institutional experience on 517 procedures].
abstract: OBJECTIVE
  To analyse the outcomes of patients undergoing Essure sterilization in a single institution, interns of complications and technique failure.
  
  
  METHODS
  Retrospective descriptive study of 517 patients underwent definitive contraception with Essure device in outpatient hysteroscopy office without anesthesia and controlled at 3 months with abdominal radiography, ultrasonography and hysterosalpingography in selected cases.
  
  
  RESULTS
  The success rates of the insertion of Essure was 96.8%, similar to data reported in the literature with 3.7% of vagal reactions, as most prevalent complication. 7 (1.35%) unintended pregnancies were observed.
  
  
  CONCLUSIONS
  Essure is a permanent birth control device, with high rate of successful insertion and a low rate of complications. Unintended pregnancies in our study are high and we must change the protocols of placement and monitoring, considering hysterosalpingography as a routine control test.
