What is a feeding gastrostomy tube?
A feeding gastrostomy tube (also called a percutaneous
gastrostomy (PEG tube or G-tube) is a tube inserted through the
abdominal wall and into the stomach to assist with feeding and
to provide nutrition.
Why is it ordered?
A feeding tube is ordered for the patient who is unable to take
in enough food or drink through the mouth to maintain his or
her body weight. The same type of tube can also be used to
remove air or liquids from the stomach.

zero level or in the operating room
Occasionally: in Vascular Interventional Radiology or the
intensive care unit.
What is involved in placing a PEG
tube?
The procedure varies, depending on where the tube is inserted.
Your tube will be inserted in:
GI Endoscopy
Before the procedure, the staff will:
- Have you sign a consent form for the procedure,
indicating that the purpose, benefits, risks and alternative
have been explained to you. If you are unable to consent for
yourself, consent will be sought from your next-of-kin, or
court-appointed guardian or a healthcare agent appointed in
accordance with a valid health care power of attorney.
- Assess your medical history and evaluate your blood work
to make sure your clotting values are normal.
- Insert an IV and may give you a dose of antibiotics.
- Shave the left upper part of the abdomen, if needed.
During the procedure, the staff will:
- Give you medicine to make you sleepy and then numb your
throat so you will not gag with the placement of the
endoscope
- Monitor your blood pressure, heart rate, and oxygen
saturation. You will receive oxygen throughout the procedure,
if needed.
- Perform an endoscopy (a small tube with a light and
camera on the end of it is put down your esophagus and into
your stomach). The endoscopy lets the doctor look at the
stomach from the inside and determine where to place the
feeding tube.
- Clean the abdomen with an antiseptic solution and numb
the skin. A tiny incision is made and the tube is placed
through the skin, or percutaneously, with the aid of the
endoscope. The procedure lasts about 45 minutes to one
hour.
Vascular Interventional Radiology
Vascular Interventional Radiology places gastrostomy tubes only
in inpatients.
The day before the procedure, the staff will:
- Have you sign a consent form for the procedure,
indicating that the purpose, benefits, risks and alternative
have been explained to you. If you are unable to consent for
yourself, consent will be sought from your next-of-kin, or
court-appointed guardian or a healthcare agent appointed in
accordance with a valid health care power of attorney.
- Assess your medical history and check your blood work to
make sure your clotting values are normal.
- Insert a nasogastric (NG) tube. This may be used to put
in the barium liquid used to show where your stomach and
intestines are, by x-ray. It is also used to put air into the
stomach before the procedure.
The morning of the procedure:
- You will have an x-ray done of your abdomen. This may be
done in your hospital room, or in Vascular Interventional
Radiology.
Before starting the procedure, the staff will:
- Insert an IV, if you don’t have one already
- Begin monitoring your blood pressure, heart rate, and
oxygen saturation.
During the procedure, the staff will:
- Give you medicine to make you sleepy
- Continue monitoring your blood pressure, heart rate, and
oxygen saturation. You will receive oxygen throughout the
procedure, if needed.
- Shave the left upper part of the abdomen, if needed.
- Clean the abdomen with an antiseptic solution
- Numb the skin.
- Inject air into the stomach through the NG tube.
- Attach a T-fastener to hold the tube in place, using a
needle
- Make a tiny incision and place the tube through the skin
into the stomach.
The procedure lasts about 45 minutes to one hour.
Duke North Operating Room (Ambulatory
Surgery)
Before the procedure:
- You will be seen by the general surgeon in the clinic for
a pre-op evaluation. The surgeon will assess your medical
history and evaluate your blood work to make sure your
clotting values are normal. During this visit, you will sign
a consent form for the procedure, indicating that the
purpose, benefits, risks and alternative have been explained
to you. If you are unable to consent for yourself, consent
will be sought from your next-of-kin, or court-appointed
guardian or a healthcare agent appointed in accordance with a
valid health care power of attorney.
- You will also have an appointment to discuss your
anesthesia in the Pre-op Screening Unit. During this visit,
you will sign a consent form for the anesthesia.
- You may not have anything to eat or drink after midnight
the night before your procedure. During your pre-op screening
visit, you will be instructed about taking your medications
on the morning of surgery.
During the procedure, the staff will:
- Insert an IV for medicines and fluids
- Give you medicine to make you sleepy and then numb your
throat so you will not gag with the placement of the
endoscope
- Monitor your blood pressure, heart rate, and oxygen
saturation. You will receive oxygen throughout the procedure,
if needed.
- Perform an endoscopy (a small tube with a light and
camera on the end of it is put down your esophagus and into
your stomach). The endoscopy lets the doctor look at the
stomach from the inside and determine where to place the
feeding tube.
- Clean the abdomen with an antiseptic solution and numb
the skin. A tiny incision is made and the tube is placed
through the skin, or percutaneously, with the aid of the
endoscope. The actual procedure lasts only about five to 10
minutes. You will be in the operating room about 45 minutes
to one hour.
Is the procedure painful?
You will be given sedation throughout the procedure, so you
should be very comfortable. Most people do not remember
anything about the procedure when they wake up. Some may
complain of some mild discomfort during the procedure or at the
tube site. If you cannot be adequately sedated, the procedure
will be stopped. Your doctor will be notified and placement
under general anesthesia will be considered.
What are the risks of the procedure?
- An allergic reaction to the medicine.
- Bleeding
- An unplanned tiny hole (perforation).
- Infection at the tube site or a fever.
- Infection inside the abdomen (peritonitis)
- The tube must not be removed or dislodged for the
next two weeks to allow the tract to form where the
tube has been placed. Dislodgement of the tube during the
first two weeks following placement can cause leakage and
infection. If this occurs you should contact your
physician immediately. This is an emergency!
What happens after the procedure?
After the procedure, a dressing is placed over the tube.
Sometimes an abdominal binder is applied to protect the tube.
Then you will be taken to your hospital room or to the recovery
area where you'll be for at least 30 minutes.
- If you are staying in the hospital, the
nurse will give report to the nurse on the floor taking care
of you. Once recovered, you will be discharged to your room.
The nasogastric tube will usually be connected to suction for
about 24 to 48 hours. A dietitian and/or floor nurse will
discuss with you how to use your tube for feeding, how to
take care of it at home, and what feeding solution is the
best for you at that time.
- If you are going home, your driver can
come and sit with you. Discharge instructions will be given.
Your IV will be taken out. The doctor will come and talk to
you or your family before you leave.
- The doctor who ordered your tube placement will make
arrangements for your follow-up. You will need to see the
doctor within 7 days for tubes placed in the operating room
and within 14 to 21 days for tubes not
placed in the operating room. Call your doctor if you have
questions.
- You and your family may learn about taking care of the
tube and doing feedings at home in several ways. You may have
instructions in clinic before the tube is placed. Your family
may receive instructions in the recovery room immediately
after tube placement. Or, you may be taught in the clinic
after the procedure or during a visit from a home health
nurse. This teaching should be done within one to two
days from the tube insertion. Please contact the
doctor who placed your tube if you have questions about who
will teach you how to use it.
- The tube cannot be used for 24 to 48
hours after insertion.
Gastrostomy tubes often need to be replaced. If cracked,
leaking, or obstructed, it can often be replaced using the same
opening.
Do I need someone to drive me home
afterward?
If you are not staying in the hospital, then yes. You will be
given sedation and you cannot drive for 24 hours after the
procedure.
When do I need to call the doctor?
Your tube should be ready to use within 24 hours unless your
doctor says otherwise.
If you have a problem with your tube, refer to the chart
below.
