Clinical Study


Diagnostic hysteroscopy is more accurate than SIS and TVUS in assessing endometrial pathology

Grimbizis GF, Tsolakidis D, Mikos T, et al. Fertil Steril. 2010;94:2721-2725.

A study of 105 women compared diagnostic hysteroscopy (DH), saline infusion sonohysterography (SIS), and transvaginal ultrasound (TVUS) in the assessment of endometrial pathology.

  • DH was the most accurate technique in the diagnosis of all endometrial pathologies (AUC=0.953) vs SIS (AUC=0.759) and TVUS (AUC=0.725)
  • DH had superior diagnostic performance vs. SIS (P<.001) and TVUS (P<0.001)
  • DH more accurately diagnosed endometrial diseases and intracavitary masses

Additionally, diseases of the endometrium (eg, hyperplasia and cancer) cannot be distinguished by SIS or TVUS.

Average time per procedure: Less than 3 minutes Average time doctors were in the exam room per procedure: Less than 13 minutes "With Endosee, we can turn over the room in 20 minutes" – Physician feedback

  • Feedback from 106 Endosee Trials with 42 Clinicians

"Endosee allowed myself and the patient a direct assessment of the uterine cavity. We were both surprised to see the reoccurrence and extent of intrauterine pathology that I was not able to appreciate on pelvic sonogram."
