[Prolapse of the ventriculoperitoneal shunt through the rectum].

The ventriculoperitoneal shunts (VPS) are commonly used to liberate the pressure of the cerebrospinal fluid in hydrocephalus. It is a very common therapy in pediatric neurosurgery. It is also considered as a safe and efficient, well tolerated control in the hydrocephalus patient. But it may bring complications. We present a case of sigmoid perforation due to a ventriculoperitoneal shunt unnoticed and symptomless until the tube broke through the rectum. The abdominal complications of VPS, their diagnosis, and management are also commented.
