Child presents with recurrent abdominal pain and bilious vomiting. Condition was diagnosed by barium follow through. Surgery was done, mesenteric widening, appendectomy, cutting the Ladd’s mesenteric widening, appendectomy, cutting the Ladd’s band. What is the diagnosis?

**Core Concept**
The condition described involves a congenital anomaly of the intestinal tract, leading to recurrent abdominal pain and bilious vomiting. It is characterized by a specific anatomical malformation that requires surgical intervention for correction.

**Why the Correct Answer is Right**
The condition is due to a malrotation of the midgut, which leads to an obstruction caused by a band of tissue, known as Ladd's band, that constricts the intestine. The barium follow-through study helps to visualize the intestinal tract and confirms the diagnosis. The surgical procedure involves cutting the Ladd's band, which is a narrow peritoneal fold that constricts the intestine, and sometimes involves a mesenteric widening or appendectomy if the appendix is also malpositioned. The mesenteric widening is done to prevent the twisting of the intestine, which can lead to ischemia.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is not relevant to the condition described, as it does not involve a congenital anomaly of the intestinal tract.
**Option B:** While this option might seem plausible, it does not specifically address the anatomical malformation and obstruction caused by Ladd's band.
**Option C:** This option is incorrect because it does not involve the specific anatomical malformation and surgical intervention described in the correct answer.

**Clinical Pearl / High-Yield Fact**
This condition is a classic example of a congenital anomaly that requires prompt surgical intervention to prevent complications such as intestinal ischemia and necrosis.

**Correct Answer:** C. Intestinal malrotation with Ladd's bands

✓ Correct Answer: B. Malrotation
