Pyloric stenosis |
| Definition: |
| Pyloric stenosis is a narrowing of the outlet from the stomach to the small intestine (called the pylorus). The condition primarily occurs in infants.
|
| Alternative Names: |
| Congenital hypertrophic pyloric stenosis; Hypertrophic pyloric stenosis; Gastric outlet obstruction |
| Causes, incidence, and risk factors: |
This condition is caused by a thickening of the muscles of the pylorus. This prevents the stomach from emptying into the small intestine. The cause of the thickening is unknown, although genetic factors may play a role. It occurs more commonly in boys than in girls and is rare in patients older than 6 months. Approximately 1 in 4,000 infants is affected with this condition. |
