This case report describes a patient presenting with acute colonic obstruction caused by rectal endometriosis, highlighting the diagnostic challenge of distinguishing such lesions from malignancy. Despite repeat colonoscopic biopsies and imaging studies failing to differentiate the condition from cancer, segmental resection with anastomosis successfully relieved symptoms and confirmed the diagnosis through histopathology. The authors review existing literature to discuss the incidence, clinical presentation, diagnostic difficulties, and treatment options for intestinal endometriosis, while also addressing the associated risk of malignancy. This paper is centrally about endometriosis — specifically extrapelvic involvement leading to colonic obstruction and the subsequent surgical management required for diagnosis and symptom relief.

Abstract

Endometriosis is often seen in gynecology practice and is treated medically. However, intestinal involvement of endometriosis causing obstruction is relatively uncommon and is hard to differentiate from malignancy before surgery. Herein, we present a case of acute colonic obstruction caused by rectal endometriosis. Repeat colonoscopic biopsy and imaging studies could not differentiate the lesion from malignancy. Segmental resection with anastomosis was performed to relieve the symptom and confirm the diagnosis. We present this unusual disease in general surgical practice and also review the literature. The incidence, symptoms, diagnosis, treatment, and risk of malignancy of intestinal endometriosis are discussed.
