Abstract

INTRODUCTION: Scar endometriosis (SE) is a rare pathology that develops in the scar tissue formed on the anterior abdominal wall usually after a cesarean section. There have been instances of women presenting to emergency or general surgery clinics with abdominal pain due to SE. MATERIALS AND METHODS: This study retrospectively reviews 19 patients who were operated on in our clinic between January 2010 and January 2017 with a prediagnosis of SE and were reported to have SE based on their pathology results. RESULTS: The mean age of the patients was 30.8 years (range: 20-49 years). The body mass indexes of 12 (63.2%) patients were ≥ 25. All patients had a history of cesarean section and 9 (47.4%) patients had undergone cesarean section once. With the exception of one patient who had her SE localized in her inguinal region, all patients had a mass localized on their anterior abdominal wall neighboring the incision and complained about cyclic pain starting in their premenstrual periods. The complaints began 2 years after their cesarean section in 10 (52.6%) patients. Mostly abdominal ultrasonography was used for diagnostic purposes. The lesions were totally excised and the SE diagnosis was made through a histopathological examination in all patients. No postoperative complications or recurrences were seen in any of the patients. CONCLUSION: Suspicion of SE is essential in women of reproductive age who have a history of cesarean section and complaints of an anterior abdominal wall mass and a pain at the scar site that is associated with their menstrual cycle. An accurate and early diagnosis can be established in such patients through a careful history and a good physical examination and possible morbidities can be prevented with an appropriate surgical intervention.
