True about IHPS is all except –
**Core Concept**
IHPS (Intestinal Hernia in Premature Small Bowel) is a rare but life-threatening condition that occurs in premature infants with intestinal atresia or stenosis. It is characterized by herniation of the proximal intestine through a defect in the abdominal wall, leading to intestinal strangulation and necrosis.
**Why the Correct Answer is Right**
IHPS is often associated with intestinal atresia or stenosis, which creates a segment of intestine that is not receiving adequate blood supply. This can lead to ischemia, further compromising the viability of the intestine. The hernia occurs through a defect in the abdominal wall, which can be a congenital weakness or a weakness created by the underlying intestinal disease.
**Why Each Wrong Option is Incorrect**
**Option A:** IHPS is more common in infants with intestinal atresia.
* Incorrect because IHPS can occur in infants with intestinal stenosis, not just atresia. The underlying condition is often a combination of both.
**Option B:** IHPS is typically diagnosed on prenatal ultrasound.
* Incorrect because IHPS is often diagnosed postnatally, usually after symptoms of intestinal obstruction or ischemia become apparent.
**Option C:** IHPS requires immediate surgical intervention.
* Incorrect because while IHPS is a surgical emergency, the initial management may involve conservative measures such as bowel rest and fluid resuscitation to stabilize the infant before surgery.
**Clinical Pearl / High-Yield Fact**
IHPS is a classic example of a "closed" abdominal wall defect, where the hernia occurs through a defect in the abdominal wall that is not immediately apparent. This can be a challenging diagnosis, as the hernia may not be visible on physical examination.
**Correct Answer:** A. IHPS is more common in infants with intestinal atresia.
