Percutaneous endoscopic gastrostomy (PEG) is popular technique to adult. But it is not so popular for babies and little children because of some difficulties and hazards with PEG. We took CT images after some air filled in a stomach. OsiriX Imaging Software built 3D-CT images. The images were very useful in puncture location and depth. A thin fiberscope did not need general anesthesia. PEG was safely succeeded to one-year girl with hydrocephalus due to bacterial meningitis using thin fiberscope and 3D-CT.
