A 42-year-old woman with changes in stool habits, nausea, and stomach aches experienced complete obstruction in the rectum. Endoscopic ultrasound demonstrated a low echoic lesion outside the rectal mucosa and endoscopic ultrasound-guided fine needle aspiration confirmed the diagnosis of bowel endometriosis. The clinical characteristics of bowel endometriosis are unspecific and this condition is sometimes misdiagnosed as a malignant tumor, irritable bowel syndrome, or any other colorectal disorder. Our aim is to show that endoscopic ultrasound-guided fine needle aspiration might be helpful for bowel endometriosis diagnosis and exclusion of other malignant disease.\nKeywords\nbowel endometriosis; bowel obstruction; endoscopic ultrasound-guided fine needle aspiration; ileus\nDOI: http://dx.doi.org/10.11152/mu-2000","source_license":"CC0","license_restricted":false}
