Abstract: A 29-year-old young woman presented to our hospital with 3 months of incomplete menstruation and no significant increase in menstrual flow. After the polyps were removed under hysteroscopy, the patient’s menstruation gradually returned to normal, and no recurrence of the disease was found after regular review. Basic information】Female, 29 years old 【Disease type】Endometrial polyp 【Visiting hospital】Guangzhou Huadu District People’s Hospital 【Visiting time】October 2018 【Treatment plan】Surgical treatment (hysteroscopic polyp removal) + diagnostic scraping + oral medication (Yimouzuo capsule + Drospirenone ethinyl estradiol tablet (II) + Cefuroxime tablet) + vulva care 【Treatment cycle】Inpatient treatment for 3 days, postoperative 1, 2 months The patient’s menstruation gradually returned to normal and her condition did not recur. The patient reported that 3 months ago, her menstrual cycle was 28-30 days, with 4-5 days to clear each time, and her menstrual flow was medium. The patient had 2 pregnancies and 2 deliveries, and her last menstrual period was on October 12, 2018, which lasted for 9 days. The patient’s basic signs were measured, the patient’s body temperature was 36.6°C, pulse rate was 88 beats/min, respiratory rate was 20 breaths/min, blood pressure was 126/78 mmHg, general condition was good, development was normal and no anemic appearance. There was no abnormality in cardiopulmonary auscultation, soft abdomen on palpation, no palpable liver or spleen, no palpable mass, and no pressure pain in the whole abdomen. Gynecologic examination was performed, and the patient was found to have normal vulvar development, married vagina in the transitional style, cervical erosion of degree I, normal posterior uterus position, normal size and activity, smooth surface without pressure pain, no masses and no thickening in the bilateral adnexal area. To further clarify the etiology, vaginal color ultrasonography was performed. The patient’s uterus was normal in size, with uniform myometrial echogenicity and no abnormalities in the bilateral adnexal areas. However, the endometrium was 9 mm thick with uneven echogenicity and 0.9×0.9 cm superfluous organisms were seen, and the blood flow signal was not obvious. Subsequently, routine blood tests, coagulation time tests, routine laboratory tests of leukocytes and electrocardiogram were performed, and the results were normal. After seeking consent from the patient and her family, the polyp was removed by hysteroscopy under general anesthesia and sent for pathological examination. After the operation, the patient was given Yimoucao capsule orally to promote uterine contraction, which was conducive to normalization of the uterus and elimination of intrauterine stagnation. The patient was also given oral cefuroxime tablets, and the vulva was scrubbed with iodophor twice a day to reduce the possibility of infection, and rested in bed for 2-3 days. The pathology report sheet reported 7 days after surgery: the endometrium showed polypoid changes and endometrial polyps. According to the pathology report results, the patient was advised to take Drospirenone Ethinyl Estradiol Tablets (II). III. Treatment effect After 3 days of standardized postoperative treatment, the patient was discharged with no infection or blood oozing from the incision and normal vital signs were measured. On review 1 month after discharge, the patient indicated that the menstrual cycle returned to 28-30 days/time, the menstrual volume was normal, the menstrual period cleared in 4-5 days, there was no dysmenorrhea during the menstrual period, and there was no blood clot among the menstrual blood. Two months after the operation, ultrasound examination was performed 3 days after menstruation, and the thickness of endometrium was 6mm, and the echogenicity was uniform, and other abnormalities were not seen. Precautions We are glad that the patient’s condition has improved, but we also advise the patient to keep her vulva clean, change her underwear regularly, avoid heavy physical labor for 7 days, avoid sexual life for 30 days, and avoid sitting in a bath for 30 days after discharge. Also pay attention to strengthen nutrition, avoid drinking alcohol, and not to take blood-activating drugs without medical indications. Since endometrial polyps are recurrent, patients are recommended to have ultrasound examination every six months. Once there is prolonged menstruation, blood clots in menstrual blood or menstrual cycle disorder, seek medical attention in time. V. Personal insight Most of the endometrial polyps occur in the reproductive age, mainly because of the strong secretion of estrogen in women, which leads to the hyperplasia of the endometrium under the stimulation of hormone level, thus forming polyps. It is very important to follow up regularly and to seek medical attention in case of irregular vaginal bleeding and other symptoms. It is recommended that women should have a gynecological examination every year even if they do not have any discomfort.
