- Etiology: placed in patients who require nutritional assistance
- AXR:
— a gastrojejunostomy tube tip that crosses to the right of the spine and then heads superiorly before turning back to the left of the spine is most likely still in the stomach
— a gastrojejunostomy tube tip that crosses to the right of the spine and then heads inferiorly before turning back to the left of the spine is most likely in the duodenum or jejunum
— correct position for the tip of a gastrojejunostomy tube after placement or replacement should be near the duodenal-jejunal junction, any other position is suspect
— any free air resulting from initial tube placement should resolve by several days after placement, free air in a symptomatic patient is suspect - Fluoroscopy: extravasation of contrast into peritoneum, contrast filling small bowel or colon before or at same time stomach is filled, gastric outlet obstruction, jejunal obstruction at the level of the jejunostomy tube tip
- Complications: malposition of the tube tip outside of the bowel, tube goes through bowel loop before entering the stomach, tube tip initial placement is in stomach, jejunal-jejunal intussusception caused by the tube tip, downstream small bowel obstruction from other etiologies, gastric outlet obstruction from the retention balloon, tube leak / fracture
- Treatment: replacement of gastrojejunostomy tube that is outside of bowel or causing a jejunal-jejunal intussusception
- Clinical: presentations include what is being infused though the gastrojejunostomy tube is being aspirated out of a nasogastric tube in the stomach / inability to infuse through gastrojejunostomy tube / abdominal distension, vomiting / abdominal pain, indications include patients at risk for aspiration / unable to tolerate gastric feeding / with significant gastroesophageal reflux
