Dissemination of endometrial cells at laparoscopy and chromotubation--a preliminary report.

Twenty-one patients undergoing laparoscopy and chromotubation were investigated for the dissemination of endometrial cells into the pelvic cavity. Prechromotubation fluid and postchromotubation fluid from the posterior cul-de-sac were aspirated and subjected to cytological assessment. Four patients (15.4%) showed evidence of endometrial cell dissemination into the pelvic cavity.
