Abstract

Objective To establish an experimental model for the study of deep nodular endometriosis.Design Induction of nodular endometriosis in baboons by grafting different uterine specimens to the peritoneal cavity.Setting Research and university facilities.Animal(s) Ten baboons, to develop a model of induced deep nodular endometriosis.Intervention(s) Biopsies of endometrium, and endometrium plus the junctional zone (JZ), full uterine thickness, and myometrium grafted to the peritoneum.Main outcome measure(s) Macroscopic descriptions recorded for observed induced lesions; staining with hematoxylin and eosin for histological evaluation and specific antibodies (CK22, CD10) for immunohistochemical studies; and analysis of surface area and volume of lesions, glandular density, and invasion of surrounding organs.Result(s) The incidence of induced nodular endometriosis was 100%, but the extent depended on the tissue grafted. Lesions induced after grafting specimens containing the JZ were statistically significantly larger than those not containing the JZ. Surrounding organ invasion was reported in more than 40% of lesions after grafting specimens containing the JZ.Conclusion(s) The first experimental model of nodular endometriosis allows investigation of deeper nodular lesions as well as invasion phenomena associated with nodular lesions.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Currently, the only animal DE model reported is through grafting uterine specimens, especially full uterine thickness, to the peritoneal cavity in baboons.

    “Currently, the only animal DE model that has been reported is through grafting uterine specimens, especially in full uterine thickness, to the peritoneal cavity in baboons98.”
  • The baboon model with induction of deep endometriosislike lesions by transplantation of endometrium and myometrium is difficult to interpret.

    “The baboon model with induction of deep endometriosislike lesions by transplantation of endometrium and myometrium (223) is difficult to interpret.”

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.
