Diverticula found 6 years after cesarean section will basically not heal on its own. If there is a desire to have children again, timely surgical treatment may be needed to prevent problems such as uterine rupture when preparing for pregnancy again. Those who do not have a desire to have children and do not have significant menstrual irregularities may be considered for regular review. Uterine scar diverticula are usually detected by vaginal ultrasound and most of them have no clinical symptoms and may present with prolonged menstrual periods. There may also be a tendency to accumulate blood and infection due to menstrual flow, which may result in a small amount of irregular vaginal bleeding even after menstruation. In patients with diverticula 6 years after cesarean section, the surgical management depends on the needs of the patient. For patients without fertility requirements, the diverticulum can be reviewed periodically or repaired with local excision depending on the patient’s condition. For patients with fertility requirements, the scar diverticulum, if relatively small, usually does not affect re-birth; for larger scar diverticula, combined hysterolaparoscopic surgery is required to repair the scar. After the cesarean section is done, attention should be paid to recuperation, reasonable diet and avoid straining to prevent the occurrence of uterine diverticulum.
