Clinical Advances in Percutaneous Endoscopic Gastrostomy: A 2023 Clinical Practice Guideline-Based Review

Percutaneous endoscopic gastrostomy (PEG) has become a standard method for enteral nutrition in patients with swallowing difficulties due to various medical conditions, including neurodegenerative diseases, stroke, and malignancies. While nutrition by PEG is superior to nasogastric nutrition in terms of patient comfort, long-term use, and nutritional efficiency, it requires selection of target patients, appropriate insertion methods, and appropriate management of complications. Appropriate use of prophylactic antibiotics can reduce wound infection and proper management of tube can reduced the possibility of complications such as tube malfunction and buried bumper syndrome. Even though most complications arising from PEG are not severe, we should do careful monitoring because sometimes life-threatening events which need surgical treatment or intensive medical care can be happened. Therefore, it is necessary to understand the indications of PEG, to properly select the method of insertion, and to know about complications that may occur during or after the PEG.
