Surgical Treatment of Scar Endometriosis Following Cesarean Section, a Series of 12 Cases

It is difficult to conduct studies with larger series in rarely observed diseases. We report our experience in managing cesarean scar endometriosis (CSE) and emphasize the diagnosis and treatment options. The objective of our study is to review the clinical characteristics of CSE and to evaluate our surgical outcomes. We have collected and documented a case series of 12 patients who underwent surgical wide en bloc excision with surrounding clear margins for CSE. Patients’ demographic features, symptoms, and clinical and operative findings were evaluated. The mean age was 34.6 years. Cyclical pain was documented in seven patients, while three patients presented with noncyclical pain. Menstrually-related enlargement of the nodule was observed in four patients, and only one patient had a complaint of dark brown leakage. The mean operation time was 26 min. The endometriotic lesions ranged from a diameter of 2 to 8 cm in size. Patients recovered completely, and no recurrence was observed. To prevent iatrogenic transplantation, additional attention is needed during surgery that exposes endometrial tissue. Complete wide excision of CSE is both diagnostic and therapeutic. To avoid unnecessary referrals, awareness of its typical clinical manifestations remains the mainstay for intervention. The most important issues to be considered during surgery is nonspreading endometriosis while manipulation.
