Endometrial polyp

Endometrial polyp

] If the polyp protrudes through the cervix into the vagina, pain (dysmenorrhea) may result.

Diagnosis

Endometrial polyps can be detected by vaginal ultrasound (sonohysterography), hysteroscopy and dilation and curettage. Detection by ultrasonography can be difficult, particularly when there is endometrial hyperplasia (excessive thickening of the endometrium). Larger polyps may be missed by curettage.cite web

Treatment

Polyps can be surgically removed using curettage or hysterescopy.cite web

] When curettage is performed, polyps may be missed. To reduce this risk, the uterus can be first explored using grasping forceps at the beginning of the curettage procedure. During hysterescopy, the polyp can be visualized and removed through the cervix. If it is a large polyp, it can be cut into sections before each section is removed. If cancerous cells are discovered, a hysterectomy may be performed. A hysterectomy would usually not be considered if cancer has been ruled out. Whichever method is used, polyps are usually treated under general anesthetic.

Prognosis and complications

Endometrial polyps are usually benign although some may be precancerous or cancerous. About 0.5% of endometrial polyps contain adenocarcinoma cells. [cite book

] Polyps can increase the risk of miscarriage in women undergoing IVF treatment. If they develop near the fallopian tubes, they may lead to difficulty in becoming pregnant. Although treatments such as hysteroscopy usually cure the polyp concerned, recurrence of endometrial polyps is frequent. Untreated, small polyps may regress on their own. [cite web

Risk factors and epidemiology

Endometrial polyps usually occur in women in their 40s and 50s. Risk factors include obesity, high blood pressure and a history of cervical polyps. Taking tamoxifen or hormone replacement therapy can also increase the risk of uterine polyps.cite book

] The use of an IntraUterine System containing levonorgestrel in women taking Tamoxifen may reduce the incidence of polyps.

It is estimated that they are present in 25% of women with abnormal vaginal bleeding.

] They are round or oval and measure between a few millimeters to several centimeters in diameter. They are usually the same red/brown color of the surrounding endometrium although large ones can appear to be a darker red. The polyps consist of dense, fibrous tissue (stroma), blood vessels and glandlike spaces lined with endometrial epithelium. If they are pedunculated, they are attached by a thin stalk (pedicle). If they are sessile, they are connected by a flat base to the uterine wall. Pedunculated polyps are more common than sessile ones.
