The use of jejunal or post pyloric feeding, where feed and fluid is delivered directly into the small intestine (jejunum) and is only indicated in certain clinical conditions (including aspiration, gastroparesis, gastric outlet obstruction or previous gastric surgery precludes gastric feeding or when early postoperative feeding after major abdominal surgery is planned).
Insertion of a jejunostomy feeding tube would take place in RHCYP Edinburgh by the specialist GI team. NHS Borders staff will be involved in the post-operative and supporting local care in collaboration with NHS Lothian.
There are different options of jejunostomy feeds available:
- Percutaneous Endoscopic Gastro-Jejunostomy (PEG-J) tube
- Gastrojejunostomy (GJ) tube (non low profile or low profile options)
- Low profile roux-en y jejunostomy tube
PEG-J, GJ and low profile roux-en y jejunostomy tube feeds should ALWAYS be given by a feed pump and never as a bolus.
- Feeds should be administered via the jejunal port of the tube
- Medications can be given via the jejunal or gastric port
- The tube should always be flushed with the recommended amount of cooled boiled water before and after feeds and before and after medications
Gastric Decompression:
Although your child/young person is not receiving feed into their stomach anymore the stomach produces juices that can build up in the stomach and cause the child/young person to retch and or vomit. A drainage bag will be attached onto the gastric port of their PEG-J or GJ tube to allow for drainage of these juices. The drainage bag is usually only required when the child/young person is receiving a feed, but some are more comfortable with the drainage bag on all the time
Percutaneous Endoscopic Gastro-Jejunostomy (PEG-J) tube?
This is a gastrostomy tube that sits in the stomach with an internal tube called an ‘intestinal tube’. The intestinal tube goes through the middle of the gastrostomy into the stomach and out of the stomach into an area of the small bowel called the jejunum. The end of the PEG-J tube has 2 ports one marked “I” through which feed and medication will be administered and the other marked “G” which will be used for gastric decompression. The gastrostomy and intestinal tube will be inserted under general anaesthetic using an endoscope.
The life span of the PEG-J tube depends on several factors: types of medications/feeds used, the acidity of the gastric fluid and tube care. The intestinal tube may require to be changed before the PEG tube.
Daily Care of the PEG-J tube
- Always wash and dry hands thoroughly before handling the tube.
- It is important that the stoma site is cleaned and dried once a day. For the first 3-4 days post PEG tube placement, sterile water or saline and gauze should be used to clean the stoma site.
- Following discharge to home, clean the stoma site with a clean cloth and unscented soap and water.
- Inspect the stoma site for signs of redness, swelling, irritation, skin breakdown and leakage. If you notice any of these signs, inform the medical team.
- Ensure the PEG-J tube stays away from the nappy/pad area.
- Do not rotate the PEG-J tube.
- It takes 2-3 weeks for the stoma to form a tract, it is important during this time not to submerge the whole area in water ~ have showers not baths. Swimming is not recommended for 6 weeks.
4-6 WEEKS AFTER THE PLACEMENT OF THE PEG TUBE
- Every week the white triangle fixator should be taken apart and the PEG tube gently pushed into the stomach by 4cm, and then pull the PEG tube back until you feel resistance. Close the white triangle fixator.
- Do not rotate the PEG-J tube.
- Do not position the fixation cover too tight as it can be uncomfortable and may damage the skin
Administering Feeds
- Feeds can be administered via the intestinal port on a PEG-J tube.
- A draining bag can be attached to the gastric port of the PEG-J tube when the feed commences.
- If the child/young person starts vomiting milk feed or you see milk in the gastric drainage bag feeds, please stop feeds and contact the medical team for advice: this may be a sign of tube migration or misplacement.
- Tube migration or misplacement should also be considered if the child or young person: is showing signs of aspiration has abdominal distension and/or has worsening diarrhoea.
Gastrojejunostomy (GJ) tube
This is a silicone feeding tube that is placed through an established gastrostomy tract, it combines a gastric and jejunal feeding tube. The tube is held in place in the stomach by an internal inflatable balloon. The decision on non-low profile or low profile will be made with you depending on your child/young person’s needs. The initial tube is placed under general anaesthetic using an endoscope. Subsequent tube changes are usually carried out in X-ray with your child/young person awake.
The life span of the GJ tube depends on several factors: types of medication/feeds used, volume of water used to inflate the balloon, the acidity of the gastric fluid and tube care.
Daily Care of the GJ Tube
- Always wash and dry hands thoroughly before handling the GJ tube.
- It is important that the stoma site is cleaned and dried at least once per day. This includes taking a bath or shower daily.
- Inspect the stoma for signs of redness, swelling, irritation, skin breakdown and leakage. If you notice any of these signs, inform the medical team.
- Clean the balloon port with cooled boiled water and cotton tipped applicator. This will help the port to function properly.
- DO NOT ROTATE THE GJ TUBE
- The water in the balloon of a GJ tube should be changed weekly (see training guidelines)
Administering Feeds
- Feeds can be administered via the jejunal port on a GJ tube.
- A drainage bag can be attached to the gastric port of the GJ tube when the feed commences.
- If the child/young person starts vomiting milk feed or you see milk in the gastric drainage bag feeds, please stop feeds and contact the medical team for advice: this may be a sign of tube migration or misplacement.
- Tube migration or misplacement should also be considered if the child or young person: is showing signs of aspiration has abdominal distension and/or has worsening diarrhoea.
Tube Blockages:
- Attempt to flush the tube with warm water using a pumping action. DO NOT USE EXCESSIVE PRESSURE WHEN FLUSHING. Leave the water for 30minutes. If this method fails, contact RHCYP for further advice.
- Do not try to administer fruit or fizzy drinks down the tube to dry and unblock it.
- If there is an extension set being used and this were to block, this can be replaced with a new extension set.
Other Information:
- If the tube comes out or becomes damaged, contact RHCYP for advice.

- For stoma infection and overgranulation see sections 3 and 8.4

Low Profile Roux-en Y Jejunostomy Tube (surgically placed)
A surgical roux-en Y jejunostomy is created via a mini-laparotomy and forms a secure means of feeding a child jejunally.
An initial REY jejunostomy tube is placed, then following the formation of the roux-en Y, this is then changed by a surgeon under general anaesthetic in theatre (around 12-18months following formation: where this is changed to a low profile jejunostomy tube
If you have had difficulty inserting the low- profile jejunostomy tube or are concerned about the position of the low- profile jejunostomy tube the child/young person should be referred to A&E where tube position should be confirmed by contrast injection under X-ray screening.
The child/young person should be observed for any signs of pain or distress with feeding. If this occurs or if feeds do not run in freely the child/young person should be referred to A&E where tube position should be confirmed by contrast injection under X-ray screening.
For more information on care for Low profile roux-en y jejunostomy tube, please see RHCYP teaching guidelines.
