Endometrial Biopsy

Engman is a fellow in reproductive endocrinology and infertility, University of Connecticut School of Medicine, Farmington, Conn. Disagreement about the cause, true incidence, and diagnostic criteria of this condition makes evaluation and management difficult. Here, 2 physicians dissect the data and offer an algorithm of assessment and treatment. Despite scanty and controversial supporting evidence, evaluation of patients with infertility or recurrent pregnancy loss for possible luteal phase deficiency LPD is firmly established in clinical practice. Although observational and retrospective studies have reported a higher incidence of LPD in women with infertility and recurrent pregnancy losses than in fertile controls, 1 – 4 no prospective study has confirmed these findings. Furthermore, studies have failed to confirm the superiority of any particular therapy. Once considered an important cause of infertility, LPD has become the subject of debate, with some experts questioning its very existence.

15 years of transcriptomic analysis on endometrial receptivity: what have we learnt?

Steven G. Arch Pathol Lab Med 1 March ; 3 : — It is well known that a number of problematic diagnostic scenarios occur relative to these specimens. Recognition of diagnostic pitfalls and practical approaches to their resolution help improve quality. Although most diagnostic pathologists encounter numerous endometrial specimens in their daily practice, many perplexing problems are still encountered when dealing with these specimens.

Additional indications include endometrial dating to define the phase of the menstrual cycle, evaluation of infertility, and evaluation of uterine.

Nevertheless, there is no consensus regarding the most suitable period of the luteal phase for performing the biopsy. OBJETIVE: This study evaluated the correlation between the histological dating of two endometrial biopsies performed in the same menstrual cycle, on luteal phase days six and ten. Dating was done according to morphometric criteria, in which an endometrium sample is considered out of phase if the minimum maturation delay is one day.

Luteal phase. Female infertility. Evaluation of the luteal phase of regularly cycling women complaining of infertility is directed towards the evaluation of corpus luteum activity and the action of progesterone on the endometrium. Endometrial maturation, whose role in human reproduction was first recognized by Jones, 1 is evaluated by the Noyes criteria.

This study evaluated the correlation between the histological dating of two endometrial samples, obtained by biopsies performed on luteal phase days 6 and 10 of the same menstrual cycle.

Raga, F. Bonilla-Musoles, E. Klein, F. The aim of the present prospective study was to obtain quantitative data on endometrial volume by three-dimensional 3D ultrasound at the time of embryo transfer in an in-vitro fertilization programme and to assess its value in predicting endometrial receptivity.

Few studies have showed the role of 3D ultrasound in the diagnosis and assessment of endometrial cancer. Three-dimensional ultrasound.

Donate Shop. If your doctor suspects you have uterine cancer, you may have some of the following tests, but you are unlikely to need all of them. The main tests for diagnosing cancer of the uterus are transvaginal ultrasound , examination of the lining of the uterus hysteroscopy and tissue sampling biopsy. A Pap test is not used to diagnose uterine cancer. The doctor will feel your abdomen to check for swelling and any masses.

To check your uterus, they will place two fingers inside your vagina while pressing on your abdomen with their other hand.

Warren Nothnick. The female reproductive system prepares the female body for conception and pregnancy through two distinct cycles, the ovarian cycle and the endometrial cycle. The human endometrium, under the influence of complex biological signals, undergoes cyclic changes in preparation for implantation and the initiation of pregnancy. An array of molecular activity, still poorly understood, gives rise to relatively consistent morphologic changes of the endometrium during each cycle. In an era of assisted reproductive technologies ART , there exists an ever-increasing demand to delineate these pathways in order to improve pregnancy rates.

Ultimately, success in the field of reproduction and fertility requires an understanding of these complex processes, from molecular to cellular to tissue, in both the healthy patient as well as in the setting of various pathologic states.

My approach to the interpretation of endometrial biopsies and curettings

Thomas Strowitzki, A. Germeyer, R. Popovici, M.

Evaluation of hyperplasias in the post treatment setting in an endometrial biopsy or curettage and avoid diagnostic are inappropriate for endometrial dating.

Endometrial thickness is a commonly measured parameter on routine gynecological ultrasound and MRI. The appearance, as well as the thickness of the endometrium, will depend on whether the patient is of reproductive age or postmenopausal and, if of reproductive age, at what point in the menstrual cycle they are examined.

The endometrium should be measured in the long axis or sagittal plane, ideally on transvaginal scanning, with the entirety of the endometrial lining through to the endocervical canal in view. Care should be taken not to include hypoechoic myometrium or intrauterine fluid in this measurement. The normal endometrium changes in appearance as well as in thickness throughout the menstrual cycle:.

The designation of normal limits of endometrial thickness rests on determining at which thickness the risk of endometrial carcinoma is significantly increased. Whilst quantitative assessment is important, endometrial morphology and the presence of risk factors for endometrial malignancy should also be taken into account when deciding whether or not endometrial sampling is indicated.

Histologic dating of the endometrium: Accuracy, reproducibility, and practical value

A major proportion of the workload in many histopathology laboratories is accounted for by endometrial biopsies, either curettage specimens or outpatient biopsy specimens. The increasing use of pipelle and other methods of biopsy not necessitating general anaesthesia has resulted in greater numbers of specimens with scant tissue, resulting in problems in assessing adequacy and in interpreting artefactual changes, some of which appear more common with outpatient biopsies.

In this review, the criteria for adequacy and common artefacts in endometrial biopsies, as well as the interpretation of endometrial biopsies in general, are discussed, concentrating on areas that cause problems for pathologists. An adequate clinical history, including knowledge of the age, menstrual history and menopausal status, and information on the use of exogenous hormones and tamoxifen, is necessary for the pathologist to critically evaluate endometrial biopsies.

Evaluation of the status of the endometrium in infertile patients, including histological dating. 3. Evacuation of products of conception, either.

Read terms. This document reflects emerging clinical and scientific advances as of the date issued and is subject to change. The information should not be construed as dictating an exclusive course of treatment or procedure to be followed. Making the distinction between hyperplasia and true precancerous lesions or true neoplasia has significant clinical effect because their differing cancer risks must be matched with an appropriate intervention to avoid undertreatment or overtreatment.

Pathologic diagnosis of premalignant lesions should use criteria and terminology that clearly distinguish between clinicopathologic entities that are managed differently. At present, the endometrial intraepithelial neoplasia schema is tailored most closely to this objective, incorporating modified pathologic criteria based upon evidence that has become available since the creation of the more widely used four-class World Health Organization schema in which atypical hyperplasia is equated with precancerous behavior.

The accuracy of dilation and curettage compared with endometrial suction curette in diagnosing precancer and excluding concurrent carcinoma is unclear. Hysteroscopy with directed biopsy is more sensitive than dilation and curettage in the diagnosis of uterine lesions. When clinically appropriate, total hysterectomy for endometrial intraepithelial neoplasia provides definitive assessment of a possible concurrent carcinoma and effectively treats premalignant lesions.
