Enteral nutrition via gastric tube insertion with an endoscopic guide is a very efficient method for patients who are unable to swallow food. The use of percutaneous endoscopic gastrostomy (PEG) has been found to be useful in many situations. Common indications for PEG are neurological disorders (dysphagia after stroke, multiple sclerosis, Guillain-Barré syndrome, Parkinson’s disease, cranial trauma, amyotrophic lateral sclerosis, poliomyelitis, and others), oncologic disorders (such as head and neck cancer), and other clinical conditions that result in impaired or diminished swallowing ability, although the patients have a functional digestive system. However, the decision about whether to use PEG tube placement should be individualized to minimize complications. Identifying risk factors for PEG tube insertion and an early decision regarding the use of gastric tube system for feeding are very important for achieving marked improvement in a patient’s nutritional status, general well-being, and prognosis. Early major PEG procedure-related complications include gastrostomy puncture-related hemorrhage, peritonitis, wound infections, injury to adjacent organs (particularly the colon), and aspiration. To avoid these early complications, first, positioning a safe gastric puncture point is very important. A colo-cutaneous fistula is a rare complication, and it occurs when the colon is accidentally punctured during guided needle puncture for initial gastrostomy placement. It seldom occurs due to internal bump-induced erosion into the adjacent colon over time. Second, the entire procedure should be performed under aseptic conditions. A skin incision of the proper length should be made on the abdominal wall with a knife for easy passage of the gastric tube into the stomach cavity. Aspiration can be prevented by frequent intra-procedural suction of the oral cavity, placing the patient in the left lateral position, and avoiding excessive air insufflation. The tube site should be kept clean, and the external bolster should be carefully secured to avoid inadvertent tube removal. The stoma tract usually matures within 7–14 days after initial gastrostomy. To avoid inadvertent removal of the gastric tube, physicians should be particularly careful in patients with arm movement and mental confusion. Fluids and medications are usually started 4 hours after the procedure. Although early feeding does not increase the risk of complications, feeding can be delayed due to the fear of wound infection. Daily review of the stoma site following PEG tube insertion should be performed. Positioning the external bolster approximately 1–2 cm from the abdominal wall is important for minimizing late complications, such as internal bolster-induced gastric ulcers, granulomas (proliferation of granulation tissue through the stoma), and others. Generally, loose positioning is recommended because it prevents pressure necrosis and buried bumper syndrome.
