What relaxes the pyloric sphincter?
Pyloric sphincter relaxation synchronized with antral contractions, allows the smaller food particles and chyme to pass out of the stomach into the duodenum [5]. Pyloric relaxation is mediated through release of inhibitory nerves, especially nitric oxide and possibly vasoactive intestinal polypeptide (VIP) [28].
What is the most commonly occurring small intestinal obstruction?

Can you live a long life without a stomach?
