All are complications of ileal resection EXCEPT:March 2004
**Core Concept**
Ileal resection refers to the surgical removal of a portion of the ileum, the final 3-4 feet of the small intestine. This type of surgery can lead to various complications due to the altered anatomy and function of the remaining intestinal segments.
**Why the Correct Answer is Right**
The ileum plays a crucial role in the absorption of bile salts, vitamin B12, and certain minerals. After ileal resection, the remaining small intestine may not be able to adequately absorb these essential nutrients, leading to complications such as:
* Bile salt malabsorption, causing diarrhea and fat malabsorption
* Vitamin B12 deficiency, resulting in anemia and neurological symptoms
* Mineral deficiencies, including iron, calcium, and magnesium
The correct answer will be a complication not directly associated with ileal resection.
**Why Each Wrong Option is Incorrect**
**Option A:** Diarrhea is a common complication of ileal resection due to bile salt malabsorption.
**Option B:** Vitamin B12 deficiency is a well-known complication of ileal resection, as the ileum is responsible for the absorption of this essential vitamin.
**Option C:** Mineral deficiencies, including iron, calcium, and magnesium, can occur after ileal resection due to impaired absorption.
**Clinical Pearl / High-Yield Fact**
When counseling patients undergoing ileal resection, it is essential to emphasize the need for lifelong supplementation with vitamin B12 and potentially other essential nutrients to prevent deficiencies.
**Correct Answer:** D.
