Enteral Nutrition II: Nasointestinal and Gastrostomy Feeding

Nasointestinal feeding delivers nutrient-rich formulas through a tube inserted via the nose into the small intestine, bypassing the esophagus and stomach. This method is recommended for short-term use, typically under four weeks, due to discomfort and tube dislodgement risks. It suits patients needing temporary nutritional support when oral intake is not possible.

Nasoduodenal feeding places the tube in the duodenum and is used for conditions like gastroparesis or severe reflux where bypassing the stomach reduces symptoms. Nasojejunal feeding extends further into the jejunum and is ideal for pancreatitis, where limiting pancreatic stimulation is crucial. Both bypass the stomach but target different intestinal segments based on patient needs.

Gastrostomy feeding creates an abdominal opening directly to the stomach, providing a stable, comfortable solution for long-term nutritional support. It is indicated for patients with conditions like stroke-induced dysphagia who cannot swallow. Tubes can be placed surgically, radiologically, or endoscopically, making it suitable for patients requiring extended enteral nutrition.

Jejunostomy feeding places a tube directly into the jejunum and is selected when stomach feeding is contraindicated, such as in chronic aspiration risk or severe reflux. It minimizes aspiration risk and is performed surgically or endoscopically for long-term nutrition. This method is reserved for patients whose conditions preclude safe gastric feeding.

Radiographic confirmation is used to verify accurate tube placement in nasointestinal feeding, ensuring the tube reaches the intended intestinal segment. This imaging step is particularly important to confirm the tube bypasses the stomach correctly and reaches the duodenum or jejunum as planned. Proper placement verification prevents complications and ensures effective nutrient delivery.

Key complications include tube displacement, infection at insertion sites, and dietary intolerances. Careful monitoring and management are essential to ensure proper nutrition and prevent adverse outcomes. A multidisciplinary team including dietitians, pharmacists, and physicians coordinates care to tailor nutrition plans and adjust treatment as needed.

Enteral nutrition delivers nutrients directly to the gastrointestinal tract through tubes, utilizing the functioning digestive system. It includes nasointestinal, gastrostomy, and jejunostomy methods for patients who cannot eat orally. Parenteral nutrition, an alternative approach, bypasses the GI tract entirely and is used when the digestive system is non-functional.
