Discover how gastrostomy (G) and gastrojejunostomy (GJ) tubes are placed, how to prepare your child for the procedure and what to expect once the procedure is complete. The majority of this page is specific to children who are patients at SickKids.

Key points

  • At SickKids, most gastrostomy (G) or gastrojejunostomy (GJ) tubes are placed by an interventional radiologist using image guidance.
  • All children receive general anesthesia and are intubated (a breathing tube will be placed) for the procedure.
  • Possible complications of G or GJ tube insertion include bleeding, abdominal organ perforation, peritonitis, blood infection, and anaesthesia-related complications.
  • All patients and families will have a consultation with a nurse practitioner or paediatrician prior to going ahead with G or GJ tube insertion.
  • If your child becomes ill before the G or GJ tube insertion, or if they do not follow fasting guidelines for the general anaesthetic, the procedure may be cancelled.
  • Your child will need to stay in the hospital for at least 3 days and will be discharged when their vital signs are stable, they can tolerate feeds, there are no signs of complications and you have learned how to care for their tube and stoma.
