Pyloric Stenosis in Early Infancy
A vomiting infant can look deceptively well between feeds.
A vomiting infant can look deceptively well between feeds. The diagnostic task is to connect a changing feeding history with evolving gastric outlet obstruction, while the safety task is to identify dehydration, acid-base disturbance, or bilious emesis before focusing on the pylorus. Pyloric stenosis is treatable, but pyloromyotomy follows—not precedes—physiological resuscitation. The clinical sequence is pattern recognition, severity assessment, ultrasound confirmation, correction of the infant’s physiology, and timely surgical treatment.
