Background:
Bowel perforation is a serious but rare complication after a ventriculoperitoneal shunt (VPS) procedure. Prior studies have reported spontaneous bowel perforation after VPS placement in adults of up to 0.07%. Transanal catheter protrusion is a potential presentation of VPS bowel perforation and places a patient at risk for both peritonitis and ventriculitis/meningitis via retrograde migration of bacteria. This delayed complication can be fatal if unrecognized, with a 15% risk of mortality secondary to ventriculitis, peritonitis, or sepsis.
Case description:
We describe a unique case of a patient with distal VPS catheter protrusion from the anus whose bowel perforation did not cause clinical sequelae of infection. We were able to manage the patient without laparotomy.
Conclusions:
A subset of patients can be managed without laparotomy and only with externalization of the ventricular shunt with antibiotics until the cerebrospinal fluid cultures finalize without growth.
