Abstract
A 58-year-old woman complaining of hematochezia was diagnosed with rectal cancer (RS, 2, cSS, N1, H0, P0). A laparo-scopic-assisted anterior resection was performed. The hard adhesion between the rectal wall and the uterus indicated that the rectal tumor directly invaded the uterus. After proximal lymph node dissection, open surgery was performed. By intraoperative enteroscopy, we recognized that the main tumor was located distal from the adhesion. Intraoperative histological examination revealed no malignancy, and the ad-hesion was diagnosed as endometriosis. We therefore report a case of rectal endometriosis for which intraoperative histo-logical examination and enteroscopy allowed for the preser-vation of the uterus. We also include a literature review.
