子宫内膜息肉 中国就医指南

Endometrial polyps are benign, localized overgrowths of endometrial glands and stroma that project into the uterine cavity. They arise from the functional layer of the endometrium and are typically attached by a stalk (pedunculated) or broad base (sessile). Though histologically benign in >95% of cases, atypical hyperplasia or malignancy—particularly in postmenopausal women or those with risk factors—must be ruled out. Pathogenesis involves dysregulated estrogen stimulation without adequate progesterone opposition, leading to abnormal endometrial proliferation. Localized alterations in sex hormone receptor expression (especially estrogen receptor alpha), angiogenic factors (e.g., VEGF), and inflammatory mediators further promote polyp formation and persistence. Epidemiologically, endometrial polyps affect approximately 10–25% of reproductive-age women and up to 35% of postmenopausal women undergoing evaluation for abnormal uterine bleeding. Prevalence rises with age, obesity, hypertension, and use of tamoxifen. Key modifiable risk factors include chronic anovulation (e.g., PCOS), unopposed estrogen exposure (exogenous or endogenous), obesity (adipose tissue aromatization increases bioavailable estradiol), hypertension, and diabetes mellitus. Non-modifiable risks include advancing age, prior pelvic infection, and history of infertility. Clinically, many polyps are asymptomatic and discovered incidentally during fertility workups or routine ultrasound. Symptomatic presentations include intermenstrual bleeding, menorrhagia, postmenopausal bleeding, and infertility—polyps impair embryo implantation by disrupting endometrial receptivity, altering local cytokine profiles, and causing mechanical interference. Recurrent pregnancy loss is also associated with untreated polyps. Quality of life impact is substantial: chronic bleeding causes fatigue and iron-deficiency anemia; anxiety around cancer risk and fertility uncertainty contributes to psychological distress; sexual discomfort due to spotting may strain relationships; and repeated diagnostic procedures (e.g., saline infusion sonography, hysteroscopy) add physical and emotional burden. In reproductive-aged patients, polyps significantly reduce natural conception rates and IVF success—studies show up to 50% improvement in live birth rates after hysteroscopic polypectomy. Early diagnosis via transvaginal ultrasound (with or without saline infusion) and definitive management through office-based or operative hysteroscopy remain cornerstones of care in reproductive medicine.
