What is a PEG?
• Definition: Percutaneous Endoscopic
Gastrostomy Tube
• Medical device used to provide nutrition and
medications
• Temporary or permanent
• Patients unable to obtain nutrition by mouth,
swallow safely or need supplementation
Composition
• Made of polyurethane or silicone
• Diameter is measured in French units (each
French unit = 0.33 millimeters). Most
common for adults is 20 Fr.
• Classified by site of insertion and intended
use
History of Feeding Tubes
• 3500 years ago to Greek and Egyptian
civilizations
• Papyrus writings: Egyptian physicians used
reed and animal bladders to rectally feed
patients things like milk, broth, wine, whey to
treat different complaints
• Rectal feeding – method of choice
for thousands of years
History – cont’d
• Difficulty accessing upper GI tract without killing
the patient. Some things remain important to
this day: not killing the patient
• 1598: Capivacceus used a hollow tube with a
bladder attached to one end, filled with nutrient
solution, down as far as patient’s esophagus
• 1617: Aquapendente (Italian professor of
anatomy and surgery) used silver tube as a
nasopharyngeal tube
History – cont’d
• 1646: Von Helmont devised flexible leather
tube for feeding into the top of esophagus
• 1710: Tubing might be used to reach all the
way to the stomach
• 1790: Oro-gastric feeding developed by John
Hunter, used a whale bone covered by eel
skin attached to a bladder pump.
History – cont’d
• 18th and 19th centuries: difficult and
uncomfortable to keep tube down a person’s
throat – rectal feeding was more accepted.
(you thought colonoscopies were messy)
• 1870: Tube was placed in mouth back toward
pharynx and mixtures of thick custards,
mashed mutton, warm milk, beef broth, eggs
and medications were given.
History – 1881
• US President James Garfield was shot and
kept alive 79 days by being rectally fed a
blend of beef broth and whisky.
• Rectal feeding (nutrient enemas) was popular
in the early 1900’s – gone out of fashion
(thankfully).
• Some medical students have re-discovered
that colonic absorption is a very fast way to
get drunk. Not a very clean method. . .

PEG
• Patient: 4 ½ month old child with inadequate
oral intake
• Technique was first published in 1980 – gold
gold standard for PEG placement
Uses
Naso-pharyngeal feeding
• ‘Fasting girls and spoilt children who refused
food’
• Device that looked like a tea pot with a very
long spout were used to force-feed patients
in mental institutions – mixtures of egg, milk,
beef tea and wine thickened with arrowroot
Delivery of enteral nutrition
•
•
•
•
Dysphagia due to stroke
Pre-op - for oral/esophageal cancer surgery
ALS
Anatomical: cleft lip and palate during the
process of correction
• Failure to thrive: premies to adults
• Persistent N/V during pregnancy
Decompression
• Gastric decompression – major trauma or
intestinal obstruction
• Provide gastric or post-surgical drainage
Delivery of Medication
• Liquid form of medication (elixir)
• Carafate slurry
• Administer medications as per guidelines

for drainage)
Relative Contraindications
• Gastric mucosal abnormalities: large gastric
varicies, portal hypertensive gastropathy

height (cm)
Pre-op
• Patient assessment

Procedure Room
• Explain procedure to patient
• Take patient to room
• Insert bite block

In the Room

• Mark
• Medicate
• Trocar
Procedure - 2
• Stylet
• Snare
• Retrieve
• Insert guidewire
Procedure - 3

• Scope withdrawn
• Guidewire threaded into insertion tube
Procedure - 4

comes through skin
• MD pulls insertion tube
• MD positions PEG in place
Procedure - 5
• GI tech places external bumper and clamp on
tube
• MD confirms placement of PEG
• GI tech inserts adapter on tube
• Measurement of tube given to RN for record
Procedure - 6
• Assess patient – abdominal binder?

COMPLICATIONS
Complications of procedure
•
•
•
•
•
•
•
Hemorrhage
Cellulitis
Gastric ulcer
Perforation of bowel
Puncture of left lobe of liver
Gastrocolic fistula
Diarrhea
Clogged tube
• Flush PEG tube
• Use brush to create opening in clogged tube
• Instill grapefruit juice or lemon-lime soda and
let sit 10 minutes
• Much easier to keep the lumen flushed
Infection
• SKIP
• Wash PEG site with soap and water as part of
daily cleansing routine
• Check VS – temperature
• Check labs - WBC
Infection, cont’d
• Turn the PEG tube – 360 with feedings/flush
• Check for PEG tube measurement
“Buried Bumper Syndrome”
• Occurs
– when the gastric bumper migrates into the
gastric wall
– when the external bumper is too tight on the
outside, causing pressure on the gastric bumper,
eroding into the stomach wall at site of stoma
• Abdominal pain, crepitus around stoma,
purulent drainage
REMOVAL OF PEG
Indications
• PEG tube no longer needed
• Persistent infection at the PEG site
• “Buried Bumper Syndrome”
• Failure, breakage or deterioration of PEG
tube
Procedure – removal of PEG: 1
• PEG tubes with rigid, fixed internal bumpers
are to be removed endoscopically.
• Bumper removed
• Cut tube pushed into stoma
• Insert snare
Procedure – Removal of PEG: 2
• Pull snare with scope
• Place endoclip
• Dress skin
NEW USES
ASPIRE
• Low risk method of weight loss
• Developed by 3 physicians:
– Dr. Sam Klein – Director of the Center for Human
Nutrition at Washington University School of
Medicine in St. Louis, Missouri
- Dr. Moshe Shike – Attending Physician and
Director of Clinical Nutrition at Memorial Sloan
Kettering Cancer Center in New York
- Dr. Stephen Solomon – Attending Physician and
Chief of IR at Memorial Sloan Kettering
Aspire Bariatrics founded in 2005 by
Drs. Klein, Shike and Solomon
• These 3 physicians combined their expertise
in the areas of nutrition, obesity,
gastroenterology, interventional radiology,
percutaneous endoscopic gastrostomy (PEG)
tubes and medical device discovery
• Modified and adapted the PEG tube to help
patients lose weight
New Approach to Weight Loss
•
•
•
•
•
Minimally invasive
Reversible
‘AspireAssist’ available in Europe
Clinical trials in the United States
Dramatic results – patients have lost an
average of 46 pounds during the first year
Procedure
• During an outpatient procedure in an
endoscopy center or surgi-center, the patient
would meet all the requirements for an
endoscopy: NPO for 8 hours, labs and EKG,
sleep study if needed, heart and blood
pressure medications taken with a sip of
water prior to arrival, ride home verified
before procedure
Procedure – cont’d
• Consent obtained by anesthesia and
endoscopist
• Procedure explained to patient with possible
complications
• Discharge instructions reviewed with patient
so he/she able to care for the fresh PEG
• Diet – normal food, drink and amounts
• Follow up visit scheduled for 10 days
Procedure – cont’d
• No diet change needed to begin
• Patient to learn healthier eating habits over
time
• Relatively inexpensive – cost of AspireAssist
device, PEG tube insertion with anesthesia
• Bariatric surgery very expensive
Aspire Assist
• After a meal, the patient can attach the
Aspire Assist device to the skin port on the
outside of the abdomen. The valve on the
skin port is opened to remove 30% of
stomach contents into the toilet
Aspire Assist - 2
• This ‘aspiration’ takes place 20 minutes after
consumption of a meal.
• Time needed to perform procedure – 5 to 10
minutes
• Weight loss is attained because 30% of
stomach contents removed 3 times/day (with
each meal), resulting in less caloric intake in
small intestines
ASPIRE
• New way to reduce portion size
• Vitamins will be prescribed to keep healthy
• Counseling sessions
• Important to drink plenty of fluids to assist
with aspiration
Caring for skin-port
• Care is similar to PEG care –
• Activity is encouraged, no deep-water diving
Removal of Skin-Port
• Reversible if not needed or wanted
Weight loss achieved
Changed mind
Removal is same as for PEG removal
Procedure under sedation to remove device
Clip the opening on the inside of the stomach
Steristrips on the outside of the opening
Closes within 2-3 days.
