My baby brother turns 40 today! He inadvertently taught me my first surgical lesson. As a 5-6 week old infant, he began having projectile vomiting. When you have seen "projectile vomiting", you never forget it. It is not the little bit of drool with a burp. It is not just upchucking on your shirt. It is literally projected across the room.

I don't know if he had a palpable "olive" (a firm, nontender, and mobile hard pylorus that is 1-2 cm in diameter) on physical exam. He was always hungry and wanted to eat, but it all came back up almost immediately. His is a diagnosis (pyloric stenosis) and exam I was good at in medical school and residency.
He had an open pyloromyotomy (pie-lore-oh-my-ot-toe-me) and in no time began to thrive. He now has a very small scar from that surgery. He is 6'5" tall and weighs about 250 lb and other than his high blood pressure he is fairly healthy.
Happy Birthday Baby Brother! Hope you have many, many more.
