It causes abrupt onset of non-bilious vomiting. it is known as non-bilious because it does not contain bile. Additionally, emesis observed during pyloric stenosis is forceful thus it is called Projectile vomiting.

Answer 2: Pyloromyotomy is a type of surgery for the treatment of hypertrophic pyloric stenosis in which incision is made in the wall of pylorus to open a channel from stomach to small intestine.
