An endometrial polyp or uterine polyp is a mass in the inner lining of the uterus. [1] They may have a large flat base or be attached to the uterus by an elongated pedicle (pedunculated). [2] [3] Pedunculated polyps are more common than sessile ones. [4] They range in size from a few millimeters to several centimeters. [3]
A polyp is an abnormal growth of tissue projecting from a mucous membrane. If it is attached to the surface by a narrow elongated stalk, it is said to be pedunculated; if it is attached without a stalk, it is said to be sessile. Polyps are commonly found in the colon, stomach, nose, ear, sinus(es), urinary bladder, and uterus.
Treatment depends on the underlying cause. [3] [2] Options may include hormonal birth control, gonadotropin-releasing hormone (GnRH) agonists, tranexamic acid, NSAIDs, and surgery such as endometrial ablation or hysterectomy. [1] [5] Polyps, adenomyosis, and cancer are generally treated by surgery. [2] Iron supplementation may be needed. [2]
Cancer of the uterus is always a concern, specifically when the bleeding occurs after menopause. Other types of cancer include cervical cancer; bleeding in that case can sometimes be triggered by postcoital bleeding. Cancers of the vagina or fallopian tubes are rare causes of hemorrhage.
The treatment choices of those referred to hospital in the UK for heavy menstrual bleeding. [20] The first line treatment option for those with HMB and no identified pathology, fibroids less than 3 cm in diameter, and/or suspected or confirmed adenomyosis is the levonorgestrel-releasing intrauterine system (LNG-IUS). [16]
Typical procedures include endometrial ablation, submucosal fibroid resection, and endometrial polypectomy. Hysteroscopy has also been used to apply the Nd:YAG laser treatment to the inside of the uterus. [7] Methods of tissue removal now include electrocautery bipolar loop resection, and morcellation. [8]
In medicine, a polypectomy is the surgical removal of an abnormal growth of tissue called a polyp. Polypectomy can be performed by excision if the polyp is external (on the skin). [ 1 ] [ additional citation(s) needed ]
Endometrial intraepithelial neoplasia (EIN) is a premalignant lesion of the uterine lining that predisposes to endometrioid endometrial adenocarcinoma. It is composed of a collection of abnormal endometrial cells, arising from the glands that line the uterus , which have a tendency over time to progress to the most common form of uterine cancer ...
