Overview
Patients with infantile pyloric stenosis usually appear ill. Physical examination of patients with infantile pyloric stenosis is usually remarkable for palpation of an abdominal mass in epigastrium.This mass, which consists of the enlarged pylorus, is referred to as the olive.
Hypothermia and tachycardia with regular pulse and tachypnea may be present. In skin examination cyanosis, poor skin turgur, jaundice and pallor may be present.
Physical Examination
The presence of palpation of an abdominal mass and visible peristalsis on physical examination is diagnostic of infantile pyloric stenosis.

Vital Signs
- Hypothermia may be present[1]
- Tachycardia with regular pulse may be present due to dehydration
- Tachypnea may be present due to dehydration
Skin
- Cyanosis may be present due to dehydration
- Poor skin turgur may be present due to dehydration
- Jaundice may be present
HEENT
- Depressed fontanelles may be present due to dehydration
- Decereased tearing may be present due to dehydration
Neck
Physical examination of neck is usually normal.
Lungs
Physical examination of lungs is usually normal.
Heart
Physical examination of heart is usually normal.
Abdomen
- Palpation of the abdomen may reveal a mass in the epigastrium. This mass, which consists of the enlarged pylorus, is referred to as the olive and is sometimes evident after the infant is given formula to drink. It is an elusive diagnostic skill requiring much patience and experience.[2]
- Palpation of a hypertrophied pylorus is very diagnostic in diagnosis of hypertrophic pyloric stenosis.[3]
- There are often palpable (or even visible) peristaltic waves due to stomach trying to force its contents past the narrowed pyloric outlet.
Back
Physical examination of back is usually normal.
Genitourinary
Physical examination of genitourinary system is usually normal.
Neuromuscular
Physical examination of neuromuscular system is usually normal.
Extremities
Physical examination of extremities is usually normal.
