Abdominal wall endometriosis: A challenging iatrogenic disease

Introduction and importance: Abdominal wall endometriosis is a rare clinical condition associated with abdominal pain and psychologic disorders. It's pathophysiology remains unclear. Clinical history and imaging findings are necessary for the diagnosis. Its management is challenging, and requires close collaboration between gynaecologists and visceral surgeons specially in complex procedures. The aims of our study are to present risk factors, clinical presentation, imaging findings and management features. It was a retrospective descriptive study including fifteen patients presenting abdominal wall endometriosis. Data about age, medical history, imaging findings, surgical procedures and outcome are reported. Cases presentation: Fifteen women were included in our study. The most common symptom was cyclic abdominal pain. Twelve of them had history of caesarean section, and three had history of myomectomy. All patients underwent ultrasound and MRI. We performed surgical excision to all cases. One patient needed large excision with abdominoplasty procedure. Clinical discussion: Abdominal wall endometriosis is a rare clinical condition with unclear pathophysiology. It occurs frequently after gynaecologic or obstetric surgery. Most reported complaint was catamenial abdominal pain with abdominal wall mass. Ultrasonography, computed tomography and MRI are useful for diagnosis, specially to eliminate differential diagnoses. Abdominal wall endometriosis management is based on surgery. Excision goals are to remove the mass and to confirm histological diagnosis of parietal endometriosis. Conclusion: Parietal endometriosis is a rare and challenging condition with unclear pathophysiology. It requires specific management. This pathology will be encountered more frequently considering the increasing rate of caesarean section.
