Which condition is identified by a triad of colicky abdominal pain, bloody "currant jelly" stool, and a sausage-shaped abdominal mass?

• A. Meckel diverticulum
• B. Hirschsprung disease
• C. Intussusception
• D. Midgut volvulus

Answer: (C)

Intussusception is characterized by the triad of colicky abdominal pain, bloody "currant jelly" stools, and a palpable abdominal mass often described as sausage-shaped. In this condition, a part of the intestine telescopes into an adjacent segment, leading to obstruction and compromised blood supply. The intense abdominal pain occurs because of the intermittent obstruction and ischemia. As the blood supply is further compromised, the ingested blood mixes with mucus, resulting in the characteristic "currant jelly" stool appearance. The abdominal mass is palpable in many cases, providing another hallmark sign of this condition.

Understanding the specific symptoms and the mechanism of intussusception helps differentiate it from other gastrointestinal conditions. Meckel diverticulum, for instance, can lead to pain and gastrointestinal bleeding, but it doesn't typically present with the same acute symptoms or the distinct presentation of "currant jelly" stools. Hirschsprung disease primarily manifests with constipation and abdominal distention rather than colicky pain and bloody stools, while midgut volvulus presents with severe pain and bilious vomiting but lacks the specific stool appearance associated with intussusception. Thus, recognizing the combination of colicky pain, the appearance of stools, and the abdominal mass is crucial for diagnosing intuss
