What are the classic symptoms of midgut volvulus?

• A. Intermittent pain and bloating
• B. Constant abdominal pain and bilious vomiting
• C. Painless hematochezia
• D. Colicky abdominal pain and diarrhea

Answer: (B)

The classic symptoms of midgut volvulus include constant abdominal pain and bilious vomiting. This condition typically occurs due to a twisting of the intestine, which can obstruct blood flow and cause the intestine to become distended. The constant nature of the abdominal pain is indicative of significant distress in the gastrointestinal tract, while bilious vomiting occurs when the obstruction prevents normal passage of intestinal contents, leading to the accumulation of bile that is then vomited.

Intermittent pain and bloating, while they may occur in other gastrointestinal conditions, do not align with the acute presentation of midgut volvulus, which is characterized by more severe and persistent symptoms. Painless hematochezia is not associated with volvulus, as bleeding usually indicates a different pathology, potentially involving mucosal injury or malignancy. Colicky abdominal pain and diarrhea are also not classic symptoms of this condition, as they suggest a different type of gastrointestinal issue, typically associated with motility disorders or infections rather than a mechanical obstruction like volvulus.
