title: Enterocutaneous fistula in the setting of ventriculoperitoneal shunt extrusion through the skin and perforation through the small bowel.
abstract: The authors report a case of a 2-year-old boy with postinfectious hydrocephalus, managed with a ventriculoperitoneal (VP) shunt and complicated by shunt extrusion through the cranial skin. The shunt was removed due to concern for infection, and the child was found to have an enterocutaneous fistula (ECF) communicating along the shunt track between the small bowel and a clavicular sinus. Self-closure of the ECF was anticipated. Thus, the fistula was managed expectantly with dressing changes of the clavicular sinus, while the patient's malnutrition was managed in accordance with World Health Organization protocols. The presentation, prognosis and management of ECFs, including the likelihood of self-resolution and the role of expectant management, are discussed. Additionally, proposed mechanisms of ECF formation in the setting of a VP shunt are discussed, with an emphasis on the roles of infection and malnutrition.
