Question

An abdominal mass is best demonstrated in congenital hypertrophic pyloric stenosis by:

• A. In palpation over the epigastrium
• B. In left hypochondriac
• C. Right iliac fossa
• D. During feeding

Answer 1

The Correct Option is D

In the condition known as congenital hypertrophic pyloric stenosis, an abdominal mass can often be better appreciated under certain circumstances. This condition is characterized by a thickening of the pylorus, which leads to obstruction. The abdominal mass, frequently described as an "olive-like" mass, is notably best detected:

- During feeding: The act of feeding causes gastric peristalsis to become more vigorous due to the obstruction, thereby making the pyloric mass more prominent and easier to palpate. This response to feeding is a classical finding in infants with pyloric stenosis and is instrumental in aiding diagnosis.
