Shunt dysfunction and constipation: could there be a link?

A ventriculoperitoneal (VP) shunt is the treatment of choice for hydrocephalus, functioning by means of a pressure differential between the ventricular system and peritoneal cavity. Constipation is frequently a concomitant problem in children with VP shunts. A case study is reported in which signs and symptoms of shunt dysfunction appear to have developed as a result of constipation. Nurses and physicians must address the need for preventing constipation much more aggressively in the population requiring shunts.
