Gastrostomy Tube (G-tube or GJ-tube) Insertion
Gastrostomy tube placement is a procedure in which a tube is placed through the abdominal wall into the stomach. A gastrojejunostomy tube is placed through the abdominal wall into the stomach and the tip is advanced into the small bowel. If necessary to empty the stomach and feed through the small bowel, a tube with two ports can be inserted. Any of these tubes provide a route for nutrition or medication when a patient is unable to feed adequately by mouth.
How do I prepare for the exam?
Most patients are admitted through the Admissions and Testing Unit about two hours prior to test time. After you check in, Admissions and Testing staff will prep you for your exam, including checking vital signs, taking any needed laboratory tests, and starting an IV if necessary.
This exam requires an empty stomach, and an NG (naso-gastric) tube may be ordered with suction to clear the contents of the stomach.
What can I expect during the exam?
The exam is conducted by an interventional radiologist, a specially trained interventional radiology technologist and a nurse.
You will lie on the exam table, and a nurse will place you on a monitor and administer sedatives. The area where the tube will be inserted will be shaved and sterilely cleaned and draped.
The radiologist will inject air into the stomach through the existing NG tube so that it can be better visualized by X-rays. A numbing medication will be injected to numb the area of the abdomen. An incision will be made and the tube will be inserted through the abdominal wall into the stomach. The tube is then secured into position by a balloon inflated within the stomach. T-fasteners are inserted temporarily to anchor the stomach wall against the abdominal wall.
The procedure generally takes 45-90 minutes.
What can I expect after the exam?
After the procedure, you will return to the Admission and Testing unit for bed rest and monitoring for approximately two hours. Detailed discharge instructions will be provided to you at this time.
