Subendometrial contractility in menstrual phase visualized by transvaginal sonography in patients with endometriosis
Open accessAbstract
Objective To describe the propagation direction of the subendometrial myometrial contractile wave in menstrual phase sonographically assessed in patients with and without endometriosis.Design Prospective study.Setting Patients and normal volunteers in a university hospital.Patients Sixteen women with (study group) and 21 without (control group) endometriosis.Interventions Patients were examined by transvaginal sonography (midsaggital plane of the uterus) and recorded on videotape for a 5-minute period.Main outcome measure Direction of propagation of contraction waves.Results The endometriosis group showed a predominant retrograde pattern whereas the control group showed a normal antegrade.Conclusion This abnormal cervix-to-fundus myometrial activity could well increase the amount of peritoneal shedding of endometrial menstrual debris, increasing the probabilities of its heterotopic implantation.

Women with endometriosis have higher and more frequent mean contraction pressure and more retrograde endometrial debris than controls.

Uterine function of rapid and directed sperm transport into the dominant tube is dysfunctional in women with endometriosis and is characterized by hyper- and dysperistalsis.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
