When are feeding G tubes not the tubes of choice?
Patients may not be candidates for feeding G tubes because of anatomic or functional reasons. Anatomic contraindications include prior gastrectomy or gastric pull-through, presence of colon adherent to the stomach, and ascites. Patients with ascites are at high risk for constantly leaking fluid through the puncture site. Functional reasons include severe gastroesophageal reflux with aspiration, gastroparesis, and gastric outlet obstruction. Decompressive G tubes may be indicated in patients with gastric outlet obstruction.
When are small bowel feeding tubes indicated?
J tubes and G-J tubes are usually reserved for patients with known severe gastroesophageal reflux with the risk of aspiration.
