Abdominal wall endometriosis is a special site of endometriosis, which is generally believed to be formed mostly when endometrial fragments are scattered in the abdominal wall incision and planted with the abdominal wall incision during a cesarean section. Under the influence of sex hormones, the endometrium will shed and appear regularly with the menstrual cycle to form menstruation, and the endometrial fragments planted in the abdominal wall incision will also shed and bleed with the menstrual cycle, but the blood cannot be discharged because the abdominal wall incision is closed, so hard nodes or lumps are formed at the abdominal wall incision. The vast majority of the masses are closely related to menstruation and are painful and gradually increase in size before or during menstruation and are relieved after menstruation. Surgery is preferred for abdominal wall endometriosis if the symptoms are obvious, because it is difficult to reach the abdominal wall lesions with abdominal wall endometriosis medication, and even if the medication is effective, the chances of recurrence are higher after stopping it, and the chances of malignancy increase as the disease progresses. Since the lesions are located in the abdominal wall and are clearly palpable by the patients themselves, the psychological stress caused by prolonged failure to heal after drug treatment is also greater, so surgery is generally preferred for abdominal wall endometriosis. Generally speaking, for small and shallow lesions, complete excision of the endometriosis lesion is sufficient; in the case of larger lesions or invasion of fascia, complete excision of the lesion makes the fascia break a large hole that is difficult to be sutured, and it is necessary to repair the part that cannot be sutured with the help of artificial patches, and because the lesion is too large and too deep, there is no guarantee that it will not recur completely after surgery. Therefore, it is best to seek medical treatment for patients with endometriosis in the abdominal wall.
