PEG feeding involves placing a feeding tube directly into the stomach through a small abdominal wall incision. It is an effective way to provide enteral nutrition to patients who cannot eat adequately for more than 4-6 weeks but have a healthy gastrointestinal tract. Potential benefits include preventing weight loss, correcting nutritional deficiencies, and improving quality of life. Complications can include the buried bumper syndrome, where the internal bumper migrates along the PEG tract, potentially causing pain or leakage. Serious complications like peritonitis or gastric outlet obstruction require emergency admission if they cause acute or chronic abdominal pain. The PEG procedure takes around 15-20 minutes under sedation and involves inserting an endoscope and guidewire through the abdominal wall and stomach

- 2. Introduction: PEG feeding, introduced into clinical practice in 1980, It is now an efective way of providing enteral feeding to patients who have functionally normal GIT but who cannot meet their nutritional needs because of inadequate oral intake. It is the preferred method of feeding when nutritional intake is likely to be inadequate for more than four to six weeks& when enteral feeding is likely to prevent further weight loss, correct nutritional defciencies& stop the decline in quality of life in patients caused by insufcient nutritional intake. The benefcial efects of gastrostomy feeding on morbidity& mortality have been described only in certain subgroups. RTs in stroke shown improved nutritional outcomes, higher likelihood of survival& earlier discharge. But gastrostomy tubes are increasingly being requested& inserted for indications where long term outcomes are uncertain.
- 3. The procedure: It is a procedure for placing a feeding tube directly into the stomach via a small incision through the abdominal wall. After aseptic prep of the abd wall&prophylactic antibiotics, an endoscope is passed via the oesophagus into the stomach. A powerful light source within the endoscope& insufation of air allows the position of the endoscope to be identifed through the abdominal wall. Use of a fnger invagination technique may also help identify the optimal site. After LA infltration, a needle is inserted through the abd wall into the stomach, along with a guide wire which is grasped using a snare via the endoscope The guide wire, the snare& the endoscope are then retracted. The guide wire is attached to the end of a gastrostomy tube, pulled back down through the oesophagus& stomach& brought out through the hole in the abdominal wall& end of the PEG tube is retained within the stomach cavity, by a wide internal bumper An external bumper is then fxed to the tube to prevent the internal bumper from moving distally in the alimentary canal.
- 4. The procedure: The procedure is usually performed under sedation& takes about 15-20 mins. Gastrostomy feeding tubes may also be placed using radiological or surgical methods, depending on technical considerations or local availability

- 6. Complication requiring admission: The “buried bumper” syndrome is a rare but serious complication in 1.5-1.9%. The internal bumper migrates from the gastric wall towards the skin, anywhere along the PEG tract, as a consequence of excessive tension between the internal/ external bumper. Symptoms may include pain on feeding, retrograde leakage of feed on to the skin&rarely gastric perforation. Correction is achieved through removing& re-siting the internal bumper endoscopically or by surgical intervention.
- 7. Complication requiring admission: Serious complications such as peritonitis or gastric outlet obstruction may present with symptoms of acute or chronic abdominal pain. Red fag signs that should prompt emergency admission are pain on feeding, external leakage of gastric contents, or bleeding within or around the gastrostomy tube.
