nasoduodenaaljejunale

Nasoduodenaaljejunale, often referred to in English as nasoduodenojejunal feeding, is a type of enteral feeding tube that is inserted through the nose and extended beyond the stomach into the duodenum or jejunum. It is used to deliver nutrition directly into the small intestine, typically in patients who cannot receive adequate nutrition through the stomach or who have a high risk of aspiration.

Indications for nasoduodenaaljejunale feeding include conditions where gastric feeding is unsafe or poorly tolerated, such as severe gastroesophageal reflux, gastroparesis, ongoing vomiting, intolerance to gastric feeds, or after certain upper gastrointestinal surgeries. It is commonly chosen for post-pyloric feeding in critically ill patients or when rapid initiation of nutrient delivery is needed and decompression of the stomach is undesirable.

Placement and verification require care. The tube is advanced from the nasal cavity through the esophagus and stomach and into the duodenum or proximal jejunum. Some tubes are guided by endoscopy, fluoroscopy, or externally assisted techniques, and many use a weighted or specially designed tip to aid passage beyond the pylorus. Placement is typically confirmed radiographically, though visual or pH testing of aspirate can aid assessment. Feeding is usually continuous, using pumps, with gradual rate adjustments and regular flushing to prevent occlusion.

Common complications include tube dislodgement or occlusion, nasal mucosal irritation or sinusitis, irritation of the pharynx, abdominal discomfort, and the risk of misplacement with potential aspiration or intestinal injury. Nasoduodenaaljejanale feeding is generally intended for short-term use and is chosen to minimize aspiration risk when gastric feeding is not suitable.
