Introduction

In general, a uterine scar diverticulum refers to a uterine incision diverticulum. A uterine incision diverticulum is a depression or small cavity that forms at the site of a previous cesarean section or other uterine surgery due to poor wound healing, creating a communication with the uterine cavity. Uterine incision diverticula are primarily caused by factors such as retroverted uterus, improper suturing, poor wound healing, or infection.

Generally, a uterine scar diverticulum refers to a cesarean section scar diverticulum. A cesarean section scar diverticulum refers to an indentation or small cavity formed at the incision site due to poor healing after surgeries such as cesarean section, which communicates with the uterine cavity. Detailed explanation is as follows:

A cesarean section scar diverticulum refers to poor healing of the uterine incision after cesarean section or other uterine surgeries, forming an indentation or cavity at the incision site that communicates with the uterine cavity. The main causes of cesarean section scar diverticulum include retroverted uterus, improper suturing, poor wound healing, infection, and other factors. Cesarean section scar diverticulum may affect women's health, including symptoms such as prolonged menstruation, increased menstrual flow, and persistent spotting. Severe cases may affect embryo implantation, increase the risk of pregnancy at the cesarean scar, implantation at the scar site, scar rupture, and even cause massive hemorrhage.

For patients without fertility requirements and with mild symptoms, medications such as levonorgestrel tablets, medroxyprogesterone acetate tablets, and compound norethindrone tablets can be used under medical guidance. If medication proves ineffective or if the patient desires fertility, surgical treatment can be considered, such as hysteroscopic surgery. Hysteroscopy allows direct visualization of the morphology and location of the diverticulum, followed by trimming of the diverticular margins, removal of scar tissue, electrocoagulation for hemostasis, and promotion of diverticulum repair.

How to Treat Uterine Scar Diverticulum

In general, a uterine scar diverticulum refers to a cesarean section scar diverticulum. The formation of a cesarean section scar diverticulum may be related to factors such as incomplete endometrial repair, impaired blood circulation at the incision site, intrauterine infection, improper suturing technique, and abnormal uterine anatomical structure. Treatment options include medication and surgical interventions. In daily life, regular gynecological examinations are recommended.

Is the treatment effect of cesarean scar diverticulum good?

In general, a uterine scar diverticulum refers to a cesarean section scar diverticulum. The treatment outcome for cesarean section scar diverticulum is relatively good, although specific results may vary from person to person. A cesarean section scar diverticulum is a cavity formed due to poor healing of the uterine incision after cesarean delivery, commonly caused by incision infection, poor approximation, ischemia, hemorrhage, improper surgical technique, or individual differences leading to non-absorption of sutures.

What should be done if the gestational sac is 5 mm away from the scar?

Under normal circumstances, scars refer to uterine scars. A gestational sac located 5 mm away from the scar may be caused by random implantation of the fertilized egg, abnormal uterine morphology, uterine scar diverticulum, adenomyosis, intrauterine adhesion syndrome, or other similar reasons. Treatment options include general management, medication, and surgical treatment, which should be conducted under a doctor's guidance.
