A woman’s menstrual cycle is once a month and lasts for about a week each time. However, we often encounter many women in the clinic who have endless menstrual dripping, which really makes these women feel bad and affects their mood and life. Especially after the cesarean section, menstrual dripping is most likely caused by the uterine scar diverticulum. The Uterine scar diverticulum causes menstrual dripping after cesarean section I. What is the Uterine scar diverticulum? Uterine scar diverticulum, also known as uterine incision scar defect. To put it more figuratively, the uterine incision has not healed properly after cesarean delivery, and the muscle layer at the uterine scar is defective, thinning and depressed, forming a crypt and a small hole, in which endometrium and menstrual blood are kept during menstruation, resulting in clinical manifestations of dripping menstrual blood, prolonged menstruation, with or without pelvic pain. Second, is the uterine scar diverticulum because the cesarean section was not done properly? Although scar diverticulum is the sequelae of poorly healed incision, it is not the result of poor surgery. The possible reasons for the formation of scar diverticulum include: 1. poor healing of incision, infection, ischemia, bleeding, suturing and other reasons formed at the weak point, so that the endometrium is vaulted and protruded; 2. ectopic endometrial incision, repeated menstrual bleeding, increased pressure to the uterine cavity rupture to form diverticulum; 3. obstructed discharge of uterine contents, increased pressure in the uterine cavity, so that the weak point of incision expands outward. make the incision weak place to expand outward, forming diverticulum. How to determine whether you have a scar diverticulum? If you have incomplete menstruation after cesarean delivery, you can be diagnosed by cathodial ultrasound, and hysteroscopy, hysterosalpingography and MRI are good diagnostic methods. What are the hazards of uterine scar diverticulum? 1.Prolonged menstrual period, vaginal bleeding for many days after normal menstruation, which affects physical and mental health. 2.Scar pregnancy may occur. 3.Serious uterine scar diverticulum may rupture the uterus when pregnant again. Tips: Experts believe that it is still possible to have another pregnancy with scar diverticulum, but close monitoring of the scar is recommended during pregnancy. V. What is the treatment for uterine scar diverticulum? 1.Observation Patients with no symptoms and no fertility requirements do not necessarily need treatment and follow-up observation. 2.Medication Oral contraceptive pills are commonly used in the treatment of scar diverticulum, which can relieve the symptoms to a certain extent, but cannot repair the uterine scar defect, and the recurrence rate is high after stopping the pills. 3.Surgical treatment According to the patient’s symptoms and the severity of the scar diverticulum defects can be considered surgical treatment, the surgical treatment can be determined according to the degree of symptoms and whether there are fertility requirements, if there is no fertility requirements, feasible hysteroscopic scar diverticulum electrosurgery, can significantly improve the symptoms of vaginal dripping bleeding. Of course, if there is a need for reproduction and the scar diverticulum is large and the local muscle layer is obviously thinning, it is better to consider local excision and repair of the scar, of course, this operation can be done vaginally or laparoscopically, and strict contraception is needed for 2 years after the operation. VI. How to prevent? The more the number of cesarean deliveries, the greater the possibility of diverticula formation. If the cesarean delivery rate is not controlled, the number of women with uterine scar diverticula will increase. Therefore, pregnant women themselves need to reduce socially-factored cesarean deliveries, and professionals need to strictly curb non-surgical indications for cesarean delivery, improve the skills and precision of surgery, pay attention to the integrity of myocardial suture alignment, and reduce post-cesarean complications.
