Pyloric stenosis, while it can also cause vomiting and abdominal discomfort, typically presents with a different type of mass, often described as an "olive" shape in the right upper quadrant, rather than the elongated "sausage" configuration seen in intussusception.

Hirschsprung's disease primarily impacts the rectum and distal colon, leading to obstruction or constipation due to lack of peristals
