Analysis of risk factors for infection in coplacement of percutaneous endoscopic gastrostomy and ventriculoperitoneal shunt.

Department of Neurosurgery, Hiroshima City Asa Hospital, Japan.


Patients with severe neurological impairment requiring tube feeding may have concomitant hydrocephalus. Coplacement of percutaneous endoscopic gastrostomy (PEG) and ventriculoperitoneal (VP) shunting is currently standard in such cases. The present study investigated the risk factors for shunt infection in such patients. The medical records of 23 patients with PEG and VP shunting were retrospectively reviewed. Correlations between shunt system infection and potential risk factors were analyzed including order of PEG and VP shunting, position of abdominal shunt catheter, diabetes mellitus, tracheostomy, and activities of daily living. Twelve patients underwent VP shunting after PEG and 11 underwent PEG after VP shunt placement. Four patients experienced shunt infection, and three required shunt revision. Three of these four patients underwent VP shunting after PEG. The period between PEG and VP shunt placement was 18, 19, and 25 days, shorter than the mean period of 29.3 days. VP shunting can be combined with PEG, but a larger study is required to clearly identify the risk factors. Administration of prophylactic antibiotics and a period of at least 1 month between the procedures are recommended, particularly if the shunt is placed after the PEG tube.
