True about blind loop syndrome, all EXCEPT
True about blind loop syndrome, all EXCEPT
Show Hint
If an anatomical blind loop causes the stasis, what definitive treatment may still be required?
Updated On: Jun 24, 2026
- Syndrome of bacterial overgrowth
- Steatorrhea, megaloblastic anemia and deficiency of fat soluble vitamins
- Surgery is not indicated
- 14C-xylose or 14C-cholylglycine breath tests are indirect tests for bacterial overgrowth
Show Solution
The Correct Option is C
Solution and Explanation
Step 1: We must find the single incorrect statement about blind loop syndrome.
Step 2: The condition is fundamentally bacterial overgrowth in a stagnant loop of small intestine, confirming option a as true.
Step 3: Bacterial deconjugation of bile salts and B12 capture explain the steatorrhoea, megaloblastic anaemia and fat-soluble vitamin loss in option b, while the 14C-labelled xylose and cholylglycine breath tests in option d are well-known indirect screens for overgrowth.
Step 4: Although antibiotics and replacement therapy form the mainstay, an underlying structural lesion that creates the stagnant loop often needs surgical correction. Saying surgery is never needed is therefore false.
\[\boxed{\text{Surgery is not indicated}}\]
