In which of the following conditions does the caecum lies in the midline below the stomach?
Incomplete or mixed rotation, which is more common, results in the small bowel occupying mainly the right side of the abdomen, with the cecum generally residing in the right upper quadrant. With mixed rotation, the volvulus may occur in the first few days of life.Also know: Complete failure of rotation, or non-rotation, results in a right-sided jejunum and ileum, a low mid-abdominal cecum, and colon residing in the left abdomen. Reverse rotation is the rarest type, and its occurrence follows two errors of re-entry of the bowel loops after the combined 270-degree counterclockwise rotation outside the abdominal cavity.
