Colonic perforation is an extremely rare complication following ventriculoperitoneal (VP) shunting. The common treatment is to remove the perforating catheter and replace it with a new one. Here we report a case of colonic perforation from VP shunting in a 2-year, 8-month-old boy who presented with the distal end of the shunt catheter protruding out of his anus. The distal catheter was removed via the anus and the perforation repaired transanally. The patient's postoperative course was uneventful. This case reminds us that we should not make another rush to perform a new shunt operation unless there are some manifestations of hydrocephalus. Potential mechanisms of migration and its management strategy are discussed.
