title: [A case of colonic obstruction due to post-operative stenosis of the colon and multiple enteroliths].
abstract: An 81-year-old man who had under gone two abdominal surgeries and temporary colostomy 30 years previously was admitted due to lower abdominal pain and vomiting. An abdominal X-ray film and abdominal CT scan showed intestinal distension and multiple calcareous deposits in the colon. Gastrografin enema examination revealed smooth stenosis at the sigmoid colon and many additional defects. Endoscopy could not be performed due to the stenosis. He did not agree to surgery. Seven months later, he was admitted again, due to colonic obstruction. Surgery was performed which revealed colonic obstruction as the source of post-operative stenosis of the sigmoid colon and multiple enteroliths. The stones consisted of a core and a hull and contained ammonium magnesium phosphate.
