A 29-years old woman, who had a history of mental retardation and abnormal habit of eating tissue papers, was admitted to our hospital because of abdominal pain and vomiting. Abdominal X-ray and CT scan demonstrated much intestinal gas, and a colonoscopy revealed obstruction caused with tissue papers and large ulcers in the sigmoid colon. Therefore, we removed the tissue papers endoscopically using a grasper. After endoscopic treatment, her symptoms were immediately improved and a few longitudinal ulcer scars were seen, three month later. The endoscopic extraction was safe and effective in the colonic obstruction with tissue papers.
