During which gestational week does malrotation with midgut volvulus form?

Explanation:
The key idea is that midgut rotation happens as the intestines return to the abdomen and complete their 270-degree counterclockwise rotation, a process centered around the 10th week of gestation. If this rotation or fixation goes awry during that return phase, malrotation can set in, creating a predisposition for midgut volvulus due to a narrow mesenteric base. That’s why this formation is linked to the 10th week. The other weeks fall outside the critical window when the midgut completes its rotation, so they’re not the typical timing for the development of malrotation with volvulus.
