Abstract
The installation of a ventricular-peritoneal (VP) shunt is a very commonly utilized surgical treatment for hydrocephalus. The literature has described the caudal end of a ventriculoperitoneal (VP) shunt migrating to a variety of locations and with migration, shunt function may be reduced. This is a report on one of the rarest complications of VP shunts: Perforation of the sigmoid colon and anal extrusion.
