Abstract

In order to relieve mechanical obstruction caused by rectal carcinoma, a bare rectal stent was inserted in the sigmoid colon of a 70-year-old female. The proce-dure was successful, and for one month the patient made good progress. She then complained of abdominal pain, however, and plain radiographs of the chest and abdomen revealed the presence of free gas in the ubdiaphragmatic area. Surgical findings showed that a spur at the proximal end of the bare rectal stent had penetrated the rectal mucosal wall. After placing a bare rectal stent for the palliative treatment of colorectal carcinoma, close follow-up to detect possible perforation of the bowel wall is necessary.

  Fig. 1 70-year-old woman with delayed colonic perforation after insertion of bare stent for rectal carcinoma. A. Radiograph obtained before insertion of the stent shows opacified colon proximal to cancerous narrowing. B. Radiograph obtained immediately after the insertion of the stent shows distal migration of contrast material (long arrow) through the stent (short arrow). C. Simple radiograph of the abdomen obtained 1 month after stent placement shows a well-shaped rectal stent (long arrow) and subdiaphragmatic free gas (short arrow) due to rectal perforation. Note too the findings of paralytic ileus.
