Duodenal Atresia – Board-Style Questions

What this deck covers

Duodenal Atresia in 20 board-style clinical cases with worked explanations. Each case gives you a clinical vignette, four options, the correct answer, and an explanation of why each of the other three is wrong, with the guideline or textbook it follows named on the answer.

Board-style teaching questions for paediatricians and trainees preparing for paediatric board, MRCPCH and licensing examinations. Written from published guidelines and standard paediatric textbooks, with the source named on every answer.

Diagnoses and management options tested

Across the 20 cases you are asked to choose between options such as: A repeat scan at term only, The signs usually appear only later in the pregnancy, A fetus that stops growing within days, Almost all of them, No, since babies cannot make bile until a week old, The blockage is high, so little bowel fills above it, A closed-loop stomach that needs decompression now, Yes, a contrast study is always needed first of all, Because the bowel beyond is already dead, Give them back through the tube to save electrolytes, Yes, exactly as it would be offered otherwise, Joining the duodenum above and below the blockage, Divide the pancreatic ring to release the duodenum, Nothing, since it only matters in older children.

Clinical pearls from this deck

• A fetal double bubble is a reason to check the chromosomes and the heart.
• A normal twenty-week scan does not exclude duodenal atresia.
• Too much fluid, too early a delivery: watch for preterm labour.
• One in three: common enough to test for, not certain enough to assume.
• The colour of the vomit tells you where the block is, not whether it is there.
• High blockage, flat abdomen; low blockage, distended abdomen.

Work through the deck once for recognition, then again a week later to test yourself — each question gives the answer and explains why every other option fails.
