Abstract

BACKGROUND:

To establish whether the ultrasound findings of minimal endometriosis are confirmed at laparoscopy and that a correlation can be established as to the anatomical sites in this mild form of the disease.

AIMS:

Patients with pain and suspicion of endometriosis had an ultrasound scan by a sonologist with expertise in endometriosis as part of their pre-operative workup.

MEASUREMENTS AND MAIN RESULTS:

The clinical histories of 53 patients who had laparoscopy to investigate pelvic pain were reviewed. Ultrasounds were performed between 2012 and 2015 by a single sonologist with expertise in endometriosis assessments. The ultrasound findings were divided into subgroups as follows - presence of uterosacral ligament thickness, thickened pericolic fat, ovarian mobility and focal tenderness. These were compared with operative findings of those patients with superficial endometriosis. Evidence Level 3 - observational studies with controls and health services research that includes adjustment for likely confounding factors.

RESULTS:

Seventy-nine percent (42/53) of the patients had laparoscopic findings consistent with their ultrasound findings (95% CI 68-90%, P < 0.0001). Of the subgroups that we reviewed, uterosacral thickening (P < 0.05) and thickened pericolic fat (P < 0.05) were the most associated with superficial endometriosis at the time of laparoscopy.

CONCLUSION:

Markers on ultrasound that reliably demonstrated inflammation (thickened uterosacral ligaments and thickened pericolic fat) were shown to be significantly associated with the disease.
