Bowel herniation resolves by the 11th week; it becomes abnormal after which gestational week?

• A. 10th Week
• B. 12th Week
• C. 14th Week
• D. 16th Week

Answer: (B)

Timing of midgut development is being tested here. The midgut herniates into the umbilical cord around 6 weeks due to rapid growth and limited abdominal space, then normally returns to the abdomen by about 10–11 weeks gestation. If the bowel remains outside the abdomen after this period, it is considered abnormal. Since the return should have occurred by 11 weeks, persistence beyond that point begins at the 12th week. Therefore, 12th week is the correct choice.
