A 41-year-old woman visited another hospital because she had bloody feces in 2011. A colonoscopy revealed a stenosis of sigmoid lumen and it got a follow-up examination. After a year she was diagnosed as intestinal endometriosis by a biopsy under colonoscopy, and had been treated by endocrine hormone therapy for two years. However in 2014 she had an abdominal pain and distension. An abdominal computed tomography (CT) showed the circumferentially thickened sigmoid wall and the dilatation of the proximal colon. She visited our hospital for a detailed examination. A colonoscopy showed severe stenosis in a similar way, and the transanal ileus tube insertion was performed. The symptom improved and sigmoidectomy was performed under laparoscopy. Histopathological findings revealed endometriosis affecting the sigmoid colon. The post-operative corse was non-eventful.
