We correlated endo-vaginal ultrasound (EVUS) results with laparoscopic
findings in 16 patients with operatively confirmed acute pelvic
inflammatory disease to evaluate the sensitivity and accuracy of EVUS for
identification of uterine and adnexal pathology. Laparoscopy confirmed
prospective sonographic abnormalities in 25 of 27 inflamed fallopian tubes
(sensitivity, 93%) and in 19 of 21 ovaries with peri-ovarian inflammation
(sensitivity, 90%). Overall accuracy for EVUS prediction of peri-ovarian or
tubal disease was 91% and 93%, respectively. However, EVUS was less
sensitive to uterine abnormalities and detected inflammatory changes in
only three of 12 confirmed cases (25%). EVUS also failed to demonstrate
small quantities of purulent fluid (less than 20 cc) in the pelvic
cul-de-sac in six of nine cases.
