Transgastrostomy jejunal intubation for enteric alimentation

Area of Science:

• Gastroenterology
• Interventional Radiology
• Nutritional Support

Background:

• Malnourished patients with adequate intestinal absorption require alternative feeding routes when oral intake is insufficient.
• Gastrostomy feeding may be contraindicated due to impaired gastric motility or aspiration risk.
• Direct jejunal feeding offers a safer alternative in specific clinical scenarios.

Purpose of the Study:

• To evaluate the utility of angiographic techniques in the placement and conversion of feeding tubes for jejunal alimentation.
• To assess the feasibility of creating combined gastrostomy-jejunostomies in patients requiring enhanced nutritional support.

Main Methods:

• Angiographic techniques were employed to convert existing gastrostomies into combined gastrostomy-jejunostomies in 14 patients.
• Combined gastrostomy-jejunal tubes were placed under local anesthesia in 17 patients.
• Fluoroscopic guidance and angiographic methods assisted in the precise placement of 11 of these tubes.

Main Results:

• The study successfully utilized angiographic techniques for both conversion and primary placement of combined gastrostomy-jejunal tubes.
• This approach provided a viable method for jejunal alimentation in patients unable to tolerate standard gastrostomy feeding.
• Successful nutritional support was achieved in all patients undergoing these procedures.

Conclusions:

• Angiographic techniques are effective in facilitating the placement and conversion of feeding tubes for jejunal alimentation.
• Combined gastrostomy-jejunostomies offer a safe and effective route for nutritional support in selected malnourished patients.
• Interventional radiology plays a key role in optimizing enteral feeding strategies.
