Which statement correctly describes a jejunostomy (J) tube?

• A. Endoscopy into the jejunum via abdominal wall
• B. Nostril into stomach
• C. Small incision into the stomach
• D. Into the colon

Answer: (A)

Jejunostomy feeding involves creating a direct access point into the jejunum through the abdominal wall, often using endoscopy to reach the jejunum and place a tract for the tube—this is the essence of a percutaneous endoscopic jejunostomy. That’s why describing endoscopy into the jejunum via the abdominal wall fits exactly: the tube delivers nutrition directly into the small intestine, bypassing the stomach.

The other descriptions point to different tubes: a tube from the nose into the stomach is a nasogastric tube, a small incision into the stomach describes a gastrostomy tube, and access into the colon would be a colostomy or similar, none of which are jejunostomy tubes.
