The lining of the inside of the uterus. The endometrium contains numerous glands and gradually increases in thickness during the menstrual cycle (see menstruation) until ovulation occurs. The surface layers are shed during menstruation if conception does not take place.
The mucous membrane which lines the interior of the UTERUS.
n. the mucous membrane lining the uterus, which is covered with columnar *epithelium. It becomes progressively thicker and more glandular and has an increased blood supply in the latter part of the menstrual cycle. This prepares the endometrium for implantation of the embryo, but if this does not occur much of the endometrium breaks down and is lost in menstruation. If pregnancy is established the endometrium becomes the *decidua, which is shed after birth. —endometrial adj.
An operation, usually done under local anaesthetic, in which the lining membrane of the UTERUS (womb) is excised using a type of LASER or DIATHERMY surgery that utilises a hysterescope (a variety of ENDOSCOPE) through which the operator can visualise the inside of the uterus. The operation is done to treat MENORRHAGIA (heavy blood loss during MENSTRUATION) and its introduction has reduced the need to perform HYSTERECTOMY for the condition.... transcervical resection of endometrium (tcre)
(TCRE) an operation, which is performed under local anaesthetic, in which the membrane lining the uterus (see endometrium) is cut away by a form of *electrosurgery using a *resectoscope, which is introduced through the cervix. Like *endometrial ablation, TCRE is used as an alternative to hysterectomy to treat abnormally heavy menstrual bleeding as it results in fewer complications and shorter stays in hospital.... transcervical resection of the endometrium
