If a second pass is to be made, the catheter should not be contaminated when being emptied of the first specimen. The tenaculum is gently removed. Pressure can be applied with cotton swabs if the tenaculum sites bleed following removal of the tenaculum. Excess blood and povidone-iodine solution are wiped from the vagina, and the vaginal speculum is removed.

A The catheter tip is inserted into the uterus fundus or until resistance is felt. B Once the catheter is in the uterus cavity, the internal piston is fully withdrawn. C A degree twisting motion is used as the catheter is moved between the uterus fundus and the internal os. Normal endometrial tissue may be described as proliferative estrogen effect or preovulatory endometrium or secretory progesterone effect or postovulatory endometrium.

Hormone therapy can be offered to patients with abnormal vaginal bleeding who have normal endometrial tissue on biopsy. If the biopsy is normal but the patient continues to experience excessive vaginal bleeding, further diagnostic work-up should occur.

Atrophic endometrium generally yields scant or insufficient tissue for diagnosis. Hormonal therapy may be considered for patients with atrophic endometrium. Persistent vaginal bleeding should warrant further diagnostic work-up. Cystic or simple hyperplasia progresses to cancer in less than 5 percent of patients. Most individuals with simple hyperplasia without any atypia can be managed with hormonal manipulation medroxyprogesterone [Provera], 10 mg daily for five days to three months or with close follow-up.

Most authors recommend a follow-up endometrial biopsy after three to 12 months, regardless of the management strategy. Atypical complex hyperplasia is a premalignant lesion that progresses to cancer in 30 to 45 percent of women. Some physicians will treat complex hyperplasia with or without atypia with hormonal therapy medroxyprogesterone, 10 to 20 mg daily for up to three months.

Biopsy specimens that suggest the presence of endometrial carcinoma 75 percent are adenocarcinoma should prompt consideration of referral to a gynecologic oncologist for definitive surgical therapy. The internal cervical os may be very tight in perimenopausal and menopausal patients.

Because of the discomfort that can be created by instrumental cervical dilation, an alternative in older patients is to insert an osmotic laminaria seaweed 3-mm dilator in the patient that morning.

Osmotic dilators cause gentle, slow opening of the cervix. The osmotic dilator is removed in the afternoon, and then the endometrial biopsy can be easily performed. Patients Report Cramping Associated with the Procedure. Intraoperative and postoperative cramping frequently accompany instrumentation of the uterine cavity. Preprocedure oral nonsteroidal anti-inflammatory medications, such as ibuprofen Motrin , can significantly reduce the prostaglandin-induced cramping.

Spraying the cervix with a topical anesthetic, such as 20 percent benzocaine, can also help with discomfort. Endometrial biopsy should not be performed in the presence of a normal or ectopic pregnancy.

All patients with the potential for pregnancy should be considered for pregnancy testing prior to the performance of the procedure. Infection Occurs Following the Procedure. Bacteremia, sepsis and acute bacterial endocarditis have been reported following endometrial biopsy.

Because postprocedure bacteremia has been noted, some authors recommend considering antibiotics in post-menopausal women at risk for endocarditis. The risk for infection appears to be small, but some physicians recommend tetracycline, mg twice daily, for four days following the procedure. Some physicians are less vigorous in obtaining specimens, and a single pass of the catheter may not yield adequate tissue. A second pass can be made with the suction catheter if it is not contaminated when it is emptied after the first pass.

The second pass almost always prevents reporting an insufficient sample. Topical anesthesia can reduce the discomfort from the tenaculum. Placement of the tenaculum can make the procedure safer for the patient.

The tenaculum stabilizes the cervix and allows the physician to straighten the uterocervical angle. The tenaculum can reduce the chances of posterior perforation when the plastic catheter is inserted through the cervix and then through the thin-walled lower uterine segment. Endometrial biopsy is a fairly easy technique to learn.

Physicians are often comfortable performing the procedure unassisted after two to five precepted procedures. Physicians who perform other gynecologic procedures find that endometrial biopsy is a natural addition to their practice.

The American Academy of Family Physicians offers a comprehensive training course in endometrial biopsy for physicians wanting intensive training. This article is adapted with permission from Zuber TJ.

This procedure takes about an hour and may require general anesthesia where drugs are used to put you into a deep sleep or conscious sedation drugs are put into a vein to make you drowsy either with local anesthesia injected into the cervix or a spinal or epidural.

Most women have little discomfort after this procedure. If cancer is found, the lab report will state what type of endometrial cancer it is like endometrioid or clear cell and what grade it is. Endometrial cancer is graded on a scale of 1 to 3 based on how much it looks like normal endometrium. See What Is Endometrial Cancer? Women with lower grade cancers are less likely to have cancer in other part of their body and are less likely to have the cancer come back after treatment recur.

If the doctor suspects hereditary non-polyposis colon cancer HNPCC as an underlying cause of the endometrial cancer, the tumor cells can be tested for protein and gene changes. If the doctor suspects that your cancer is advanced, you'll probably have to have other tests to look for cancer spread. A plain x-ray of your chest may be done to see if cancer has spread to your lungs. The CT scan is an x-ray procedure that creates detailed, cross-sectional images of the inside of your body.

For a CT scan, you lie on a table while X-rays are done. Instead of taking one picture, like a standard x-ray, a CT scanner takes many pictures as the camera rotates around you.

A computer then combines these pictures into an image of a slice of your body. The machine will take pictures of many slices of the part of your body that's being studied. CT scans are not used to diagnose endometrial cancer. But they can help see if the cancer has spread to other organs and to see if it has come back after treatment.

MRI scans use radio waves and strong magnets instead of x-rays. The energy from the radio waves is absorbed and then released in a pattern formed by the type of tissue and by certain diseases. A computer translates the pattern of radio waves given off by the tissues into a very detailed image of the inside of the body. This creates cross sectional slices of the body like a CT scanner and it also makes slices that are parallel with the length of your body.

MRI scans are very helpful for looking at the brain and spinal cord. Some doctors also think MRI is a good way to tell whether, and how far, the endometrial cancer has grown into the body of the uterus. MRI scans may also help find enlarged lymph nodes with a special technique that uses very tiny particles of iron oxide.

These are given into a vein and settle into lymph nodes where they can be spotted by MRI. In this test radioactive glucose sugar is given to look for cancer cells. Because cancers use glucose sugar at a higher rate than normal tissues, the radioactivity will tend to collect in the cancer. A scanner can spot the radioactive deposits.
