With the increase in cesarean sections, the incidence of abdominal wall endometriosis has increased. Young patients with painful nodules in the abdominal wall are often seen in the outpatient clinic, often with a history of cesarean section, and nodules are found just below the scar a few months after surgery, with pain and enlargement during menstruation and relief after menstruation. With each menstrual period, the hard nodule will gradually increase in size and the pain sensation will become more pronounced. Most patients will come to the hospital and undergo surgery to remove the lesion at 1-3 cm, with a very low recurrence rate after surgery. However, there are some patients who are afraid of surgery and have been afraid to seek medical attention, or listen to charlatan doctors and delay their condition with medication. They wait until the mass is as large as 5-6 cm before coming to the clinic, at which time the surgery requires mesh repair because the lesion is too large and more fascia and muscle tissue is removed, resulting in a local defect. Surgery is preferred for endometriosis with abdominal wall scarring, with complete excision and almost no recurrence, and medication cannot be complete and is less effective. Young patients are advised not to delay their condition because of fear, making a minor surgery into a major one. Nor should they delay the best time for treatment with the mentality of operating together with the next cesarean delivery.
