Apple peel bowel with loss of dorsal mesentery is feature of which type of ileal atresia?
**Core Concept**
The question is testing the knowledge of a specific type of intestinal atresia, a congenital anomaly characterized by a complete or partial obstruction of the intestine. The "apple peel bowel" describes a characteristic radiographic feature of this condition, where the intestine is shaped like an apple peel due to its abnormal development.
**Why the Correct Answer is Right**
The correct answer is associated with a type of ileal atresia known as **midgut volvulus**. This condition results from an abnormal rotation of the midgut during embryonic development, leading to twisting of the intestine around its mesenteric axis. The loss of the dorsal mesentery is a hallmark of this condition, as the twisting and subsequent ischemia lead to the retraction and subsequent loss of the mesenteric attachments. The "apple peel bowel" appearance is due to the characteristic narrowing and thinning of the intestinal wall in the affected segment.
**Why Each Wrong Option is Incorrect**
* **Option A:** This option is incorrect because it does not accurately describe the characteristic features of the type of ileal atresia being tested.
* **Option B:** This option may be a distractor, but it is not the correct answer. While it may describe a similar type of intestinal anomaly, it does not specifically match the "apple peel bowel" description.
* **Option D:** This option is incorrect because it does not accurately describe the type of ileal atresia being tested.
**Clinical Pearl / High-Yield Fact**
The "apple peel bowel" sign is a classic radiographic feature of midgut volvulus, and its recognition is crucial for early diagnosis and treatment of this condition. This sign is often associated with a high risk of intestinal ischemia and necrosis, making prompt surgical intervention essential.
**Correct Answer:** C.
