title: [Perforation of the intestine by a peritoneal tube 10 years after a ventriculo-peritoneal shunt].
abstract: A case is reported of intestinal perforation by a ventriculoperitoneal shunt (V-P shunt) tube 10 years after V-P shunt. A 49-year-old male received V-P shunt for normal pressure hydrocephalus following subarachnoid hemorrhage. Ten years later he was admitted to our department with an abscess on the anterior chest and on the abdominal wall along the shunt tube. When CT scan revealed that the peritoneal tube had perforated the bowel, the shunt was removed. During the operation it was found that the peritoneal tube was wrapped with fibrous tissue and that it had perforated the intestine. The subcutaneous abscess healed after the patient received systemic antibiotics. He was discharged and returned to work. We discussed the mechanism of bowel perforation in this case. It is assumed that bowel perforation occurred because of continuous friction at the same site of the bowel wall after the peritoneal tube received fibrous encasement in the abdominal cavity. Bowel perforation was diagnosed ten years after the V-P shunt in this case. To our knowledge, this is the longest period amongst reported cases.
