Triad of vomiting, abdominal distension and ”String of beads” sign on abdominal X-ray is typically suggestive of?
**Core Concept**
The triad of vomiting, abdominal distension, and a "string of beads" sign on abdominal X-ray is related to **intestinal obstruction**, which is a mechanical or functional blockage of the intestine. This condition can lead to severe complications if not promptly diagnosed and treated. The "string of beads" sign is characteristic of a specific type of intestinal obstruction.
**Why the Correct Answer is Right**
The correct answer is related to the **pathophysiology of intestinal obstruction**, where the "string of beads" sign represents multiple small air pockets in the intestine, typically seen in **partial obstruction** or in conditions where there is intermittent obstruction. This sign is often associated with **mechanical obstruction** due to conditions like **adhesions**, **hernias**, or **volvulus**.
**Why Each Wrong Option is Incorrect**
**Option A:** Incorrect because it does not typically present with the "string of beads" sign.
**Option B:** Incorrect as it usually presents with different radiological findings.
**Option C:** Incorrect because, although it can cause obstruction, the specific radiological sign mentioned is not characteristic.
**Clinical Pearl / High-Yield Fact**
The "string of beads" sign is a critical radiological finding that suggests the presence of an **intestinal obstruction**, particularly one that is partial or intermittent. Recognizing this sign can aid in the prompt diagnosis and management of intestinal obstruction.
**Correct Answer:** D. Intestinal Obstruction.
