Post-procedure

The patient should fast for 6 h before commencement of enteral feeding via feeding gastrostomy.

Regular flushing following feeding to prevent blockage is recommended. If blocked, warm or carbonated water can be used to remove blockage.

Gastrojejunostomy

A gastrojejunostomy begins similar to an RIG, but the needle is angled toward the pylorus. A torquable catheter is passed through the pylorus into the duodenum, and a guidewire is advanced past the ligament of Treitz. The tract is then dilated, and a 14–18-French catheter is situated over the guidewire, lying in the proximal small intestine. Contrast medium is injected to confirm positioning by fluoroscopy.
