Abstract

Background

Scar endometriosis (EM) is defined by the presence of endometrial-like tissue outside the uterine cavity within the scar region after abdominal or pelvic surgery. It is a form of abdominal wall EM.

This systematic review addresses the question of whether women after cesarean delivery (CD) are more frequently affected by scar EM than women after other pelvic surgical procedures. The primary aim is to analyze the distribution of previous operations in patients with scar EM. Secondarily, symptoms, diagnosis, and treatment are described.

Methods

A systematic literature search in MEDLINE (Pubmed) was performed. Twelve studies were included.

Results

The terminology of scar EM is unspecific and the descriptions are, therefore, of limited comparability among authors. In 64–96%, patients with scar EM had a history of CD, followed by laparoscopy, laparotomy, and episiotomy. The main symptoms were pain, often cyclical, and the presence of local swelling. For diagnosis ultrasound, CT scan and MR imaging were used. All patients had undergone surgical resection and the diagnosis was confirmed.

Conclusion

Most often scar EM develops after CD. Diagnosis and treatment are often delayed. As an objective classifications system is missing, we propose a simple objective descriptive tool for abdominal wall EM.
