Sufficient energy and essential nutrients are vital for normal growth and development in childhood. Ideally, nutrition should be provided orally. However, if the gastrointestinal system is functional, enteral tube feeding can be used when nutritional requirements cannot be provided orally, thus providing nutritional benefits and enabling positive disease management in pediatric patients. Postoperative care in children allows monitoring of the position and functionality of the tube; performing nutrition intolerance, growth, hydration, and nutritional assessments; and performing metabolic and complication follow-ups. Tube feeding in pediatric patients is beneficial and has positive effects in controlling and managing diseases and providing appropriate nutrition in children. However, in postoperative patients, it is important to prevent potential complications, which can be classified into 5 groups: mechanical, gastrointestinal, metabolic, infectious, and pulmonary complications. Important points for managing complications include having enteral nutrition practices based on evidence-based guidelines, sharing outcomes with nurses working in clinical settings, creating enteral feeding guides in clinical settings, providing patients/patients' family with training in line with these guides, and maintaining follow-ups at home. This literature review discusses complications and practices regarding the management of complications after percutaneous endoscopic gastrostomy.
