pyloric obstruction and dilation

pyloric obstruction and dilation

[pīlôr′ik]
Etymology: Gk, pyle, gate, ouros, guard; L, obstruere, to build against, dilatare, to widen
a reaction of the stomach to pyloric obstruction, which increases the resistance to the expulsion of partly digested food from the stomach. As a result, the stomach may become hypertrophied, then dilated. Excessive consumption of food and beverages contributes to the condition.
