[Anal extrusion: a complication of ventriculo-peritoneal shunt for hydrocephalus (author's transl)].

The authors report a case of rectal perforation eight months after the placement of a ventriculo-peritoneal shunt. There was no peritonitis, but an "E. coli" meningitis was found. The patient died two hours after surgical removal of the shunt. At autopsy, a perforation by the tip of the catheter was found in the anterior face of the rectosigmoid.
