What is a scar diverticulum?

Generally, a scar diverticulum refers to a uterine incision diverticulum. A uterine incision diverticulum is a pouch-like pathological structure formed due to poor healing of the surgical wound after uterine surgery, causing discontinuity in the endometrium and muscular layer at the incision site, which protrudes outward from the uterine cavity. Detailed analysis is as follows:

A uterine incision diverticulum is a cavity formed by poor healing of the uterine incision following cesarean section. It is commonly caused by various factors such as wound infection, improper wound alignment, ischemia, bleeding, improper surgical technique, and non-absorption of sutures due to individual differences. Symptoms of a uterine incision diverticulum mainly include prolonged menstruation, heavy menstrual bleeding, extended bleeding duration, and difficulty in complete clearance of menstrual blood. In addition, some patients may experience chronic lower abdominal pain or menstrual cramps. In some cases, it may lead to uterine rupture during pregnancy or childbirth, endangering the lives of both mother and baby.

For patients with asymptomatic or mildly symptomatic uterine incision diverticula, where the diverticulum is small and located in a relatively safe position, regular follow-up observation may be chosen without special treatment. For patients experiencing symptoms such as prolonged menstruation and increased menstrual flow, medications such as compound norethisterone tablets, dydrogesterone tablets, and levonorgestrel tablets may be taken under medical guidance to alleviate symptoms. Patients with larger diverticula or those who do not respond to medication may require surgical removal of the diverticulum.

If a uterine incision diverticulum is detected, it is recommended to seek timely medical consultation at a hospital, complete relevant auxiliary examinations, and determine whether treatment is necessary under the guidance of a physician.
