Q: What is the advantage of intraduodenal feeding beside less chances of aspiration pneumonia?

Answer: Intraduodenal feeding causes

• a stronger GI response than intragastric feeding
• stimulates gallbladder contractions,
• accelerates small bowel transit time, and
• increases cholecystokinin and pancreatic polypeptide release

(In contrast, jejunal feeding does not stimulate pancreatic secretion, as is seen in intragastric or intraduodenal feeding)
