Percutaneous Endoscopic Gastrostomy (PEG)

Percutaneous Endoscopic Gastrostomy Ernakulam

What is Percutaneous Endoscopic Gastrostomy (PEG)?

This is a medical procedure that involves the use of the endoscopic technique to provide nutrition in the form of foods & liquids and medication directly into the stomach using a PEG tube. This procedure is usually provided to patients who have trouble swallowing the food or who are sedated so that the patient receives the adequate level of nutrition. It employs the natural system of digestion artificially even though it bypasses the mouth.

The PEG tube is the small feeding tube that is inserted into the stomach through the abdominal wall. PEG tube is also used for stomach decompression in some cases like Gastric volvulus, which is the twisting of part or the whole stomach and also the bowel obstruction by a malignant mass. PEG tube could be used to provide gastric or post-surgical drainage.

PEG Procedure

The three stages of the PEG procedure are:

Pre-Procedure

  • The patient will have a consultation with the doctor where his/her medical history will be reviewed. The doctor must be informed of any previous conditions of the heart or lungs, any tendency to bleed and allergies to any medication.
  • The doctor will then discuss the procedure with the patient and will answer the questions that the patient will have.
  • Please inform the doctor of the medications and supplements, you are presently taking. You might have to stop taking Ibuprofen or aspirin, before the procedure.
  • Please refrain from eating and drinking 6-12 hours prior to procedure.

During Procedure

  • The patient will be administered a pain reliever and a sedative intravenously that will induce drowsiness and relaxation.
  • Patient will be administered an anaesthetic near the site of insertion of the PEG tube.
  • The endoscope, a thin flexible tube with a camera at one end, will be inserted through the mouth and this will be used to position the PEG tube correctly by resting it in the stomach. The endoscope will not stop the patient from breathing.
  • The doctor will then create a small incision in the abdominal wall for the allowing the PEG tube to exit.
  • This procedure usually lasts from 30 minutes to an hour.

Post-Procedure

  • The patient will be kept under observation for sometime to check for any complications.
  • The exit PEG tube will be strapped to the abdomen using tape.
  • Sterile gauze dressing will be applied around the incision area.
  • The dressing will be removed once the incision site has healed and this area will be washed.
  • The PEG tube might witness some drainage in the first couple of days.
  • The doctor with the help of a dietician will assist the patient in using the PEG tube for feeding.
  • The patient might experience mild pain or soreness in the abdomen area where the PEG tube was inserted.
  • The doctor might prescribe some pain relievers for this.
  • The PEG tube has to be taken care of properly and some PEG tubes need replacement after couple of months and others might last for years.
