Needle Entry And Contrast Injection

The site for the first T-fastener is selected. The location should be a reasonable distance from the G tube site (2-3cm if possible). The needle (with T fastener inside) is placed through the skin under fluoro and directed to the gastric wall. As the needle pushes on the wall the indentation will be seen on fluoro if the c-arm is RAO 20-30 degrees. The needle is then advanced into the lumen of the stomach with a short controlled burst of pressure. Once the tip is in the lumen contrast is dripped through the needle under fluoro. The contrast should normally be seen to drip to the stomach wall and the rugal folds will be appreciated.
