Endoscopic approaches to enteral nutritional support

Area of Science:

• Gastroenterology
• Clinical Nutrition
• Medical Devices

Background:

• Enteral nutrition is physiologically superior to parenteral nutrition, offering reduced infection risks.
• Nutritional support methods range from short-term nasal tubes to long-term percutaneous access.
• Tube feeding choices depend on disease acuity, duration, and specific patient complications like aspiration.

Purpose of the Study:

• To review and compare various enteral nutrition delivery methods.
• To outline indications for different tube feeding techniques.
• To discuss endoscopic placement strategies for nutritional support.

Main Methods:

• Review of current literature on enteral feeding tube placement and utilization.
• Comparison of naso-enteric, gastrostomy, and jejunostomy tube types.
• Analysis of indications and complications associated with each method.

Main Results:

• Naso-gastric tubes suit most critically ill patients; trans-pyloric tubes are for regurgitation/aspiration.
• Deep naso-jejunal feeding is indicated for severe acute pancreatitis.
• Percutaneous endoscopic gastrostomy (PEG) is standard for long-term support; jejunal extensions can have issues, while direct percutaneous endoscopic jejunostomy may be more robust.

Conclusions:

• Enteral feeding is preferred, with tube selection guided by clinical need and duration.
• Endoscopic techniques offer various options for nutritional support.
• Careful consideration of tube type and placement is crucial for effective and safe nutritional therapy.
