How precise is histologic dating of endometrium using the standard dating criteria
To understand developing ureteroplacental circulation, a basic knowledge of the anatomy and physiology of uterine blood flow is helpful. Blood to the uterus is from the paired uterine arteries, which are branches of the anterior division of the internal iliac artery. As each uterine artery enters the uterus at the uterocervical junction, it ascends along the lateral uterine wall and produces multiple penetrating arcuate branches.
The phase of the cycle was determined by the menstrual history and histologic dating of the endometrium. The patients were similarly divided into four groups and immunohistochemical detection of Bcl-2, p53 and Ki expression was carried out using the methods described above.
Immunohistochemistry was used to detect the expression of these proteins in endometrial polyps. One hundred and eighteen normal endometrial biopsies were used as controls. Similar findings were observed in the normal endometrium. In the cycling endometrium, proliferation and apoptosis are tightly regulated by the interplay between oestrogens and progesterone, with the latter down-regulating the expression of apoptosis-blocking proteins such as Bcl However, the observation that endometrial polyps can regress spontaneously, suggests that the post-ovulatory rise in progesterone could affect polyp growth by preventing proliferation while stimulating apoptosis in a similar way to that which occurs in the cycling endometrium.
METHODS Seventy-eight premenopausal patients with endometrial polyps diagnosed either by transvaginal sonography or sonohysterography were submitted to polypectomy using the Bettocchi hysteroscope Karl Storz, Tuttligen, Germany from March to November The procedure was carried out in different phases of the menstrual cycle and, in most cases, cervical dilatation was not required.

Aetna considers the endometrial brush Tao brush an acceptable alternative to an endometrial suction curette e. Aetna considers sentinel lymph node mapping medically necessary for pathologic evaluation and surgical staging in persons with endometrial cancer. Aetna considers the following experimental and investigational because the effectiveness of these approaches has not been established: Background The National Cancer Institute NCI, has stated that there is insufficient evidence to establish whether a decrease in mortality from endometrial cancer occurs with screening by endometrial sampling.
The NCI notes that based on solid evidence, endometrial biopsy sampling may result in discomfort, bleeding, infection, and in rare cases uterine perforation. In addition, risks associated with false-positive test results include anxiety and additional diagnostic testing and surgery. Furthermore, endometrial cancers may be missed on endometrial sampling. The Pipelle endometrial sampling device is the most popular method for sampling the endometrial lining Guido, Various types of brushes have also been used for endometrial sampling.
Is endometrial biopsy really necessary? Speed points out that in women with suspected luteal phase deficiency, ideally endometrial biopsy should be carried out 1. A defective luteal phase DLP results from a relative deficiency in secretion of progesterone by the corpus luteum. Endometrial biopsy remains the classical way to diagnose an inadequate luteal phase. A study 2 which evaluated biopsies in women showed that diagnosis of LPD in both infertile and fertile women represents only a chance event; and hence luteal phase evaluation by histological dating of the endometrium is not worthwhile.
Moreover because of the discomfort and expense associated with endometrial biopsy, attention has turned to direct measurements of plasma progesterone levels as a means to rule out an inadequate luteal phase.
However, the intra- and interobserver variability inherent in dating the product of the endometrial biopsy-the endometrium-has led to the current situation, in which, in approximately 20% of cases, variability attributed to the pathologist alone is determinant of whether a given biopsy in “in phase” or out of phase (ie, an assigned postovulatory date that is at least 2 days behind the chronologic date).
Endometrial biopsy performed for histologic dating does not distinguish fertile from infertile women.
