This can help to diagnose a specific condition. When the tissue sample is examined under the microscope, abnormal cells may be identified. structural – such as swelling in a particular organ.functional – such as kidney or liver problems.When a biopsy may be neededĪ biopsy can be used to investigate abnormalities, which can be: The term 'biopsy' is often used to refer to both the act of taking the sample and the tissue sample itself. Three or four up and down passes are recommended to obtain adequate tissue and reduce the probability of an insufficient sample for diagnosis.A biopsy is a medical procedure that involves taking a small sample of body tissue so it can be examined under a microscope.Ī tissue sample can be taken from almost anywhere on or in your body, including the skin, organs and other structures. 17 To maintain the vacuum within the sample pipelle, the physician must ensure that the distal tip containing the curette opening does not exit the endometrial cavity. The catheter is then continuously rotated 360 degrees by rolling or twirling the sheath between two fingers while simultaneously moving the catheter between the uterine fundus and the internal cervical os using an in and out motion ( Figure 1).

With the sheath positioned within the uterine cavity and stabilized with the thumb and index finger of one hand, the internal piston on the catheter is rapidly and fully withdrawn the full permissible distance to create suction at the catheter tip.
Traction on the tenaculum, if used, should then be released. A pressure release may be detected after passing through the internal cervical os, and the next resistance felt will be the fundus. The physician should avoid contamination from vaginal tissue. Next, the physician should insert the endometrial biopsy catheter through the cervical canal and advance it to the uterine fundus according to the depth obtained from sounding.
Systematic review and meta-analysis of randomized controlled trials with consistent findings showing reduced biopsy-associated pain Two randomized controlled trials demonstrating more adverse effects without increased ease of biopsyĬonsider using topical lidocaine to reduce procedure-associated pain during endometrial biopsy. 3ĭo not routinely use oral misoprostol (Cytotec) before endometrial biopsy. Women with postmenopausal bleeding but no risk factors for endometrial hyperplasia or cancer may have transvaginal ultrasonography or endometrial biopsy as a first-line approach to evaluation.
4, 8Įxpert opinion and consensus guidelines in the absence of clinical trials Postmenopausal women and women with persistent or recurrent symptoms should receive further evaluation even when biopsy results are normal because blind sampling may miss focal lesions.Įndometrial biopsy should be performed for patients with abnormal uterine bleeding who are 45 years or older, and in younger patients with a significant history of unopposed estrogen exposure, persistent bleeding, or in whom medical management is ineffective. Patients should be referred for further evaluation if the procedure fails or an insufficient sample is obtained. Cramping is a common adverse effect, but serious complications are rare. A tenaculum should be applied only if required by cervical mobility or uterocervical angulation because it increases pain and lengthens procedure times. Nonsteroidal anti-inflammatory drugs can be administered orally before the procedure, and topical lidocaine can be applied to the cervix before starting the procedure to reduce procedure-associated pain. Tissue sampling occurs by rolling the catheter while moving it in and out of the uterine cavity. The catheter's piston is then drawn out to create suction. The biopsy is performed with an endometrial biopsy catheter that is inserted through the cervix into the uterine cavity. Pregnancy is the only absolute contraindication to the procedure. Endometrial biopsy is highly specific for diagnosing atypical hyperplasia and endometrial cancer in postmenopausal women. Endometrial biopsy is a safe and efficient method to evaluate the endometrium for a variety of indications, most commonly abnormal uterine bleeding and postmenopausal bleeding.
