hyperkinetic cecum syndrome

Under physiological conditions, all sides of the cecum are covered with peritoneum, but 5% of people have no peritoneum behind the upper segment of the cecum and have underdeveloped mesangium, so they have a certain degree of activity, but the range of activity should not exceed 6cm. However, if the right colonic mesangium fails to fuse with the lateral peritoneum in the embryonic stage, the activity of the cecum and ascending colon can be greatly enhanced, even if they are still in the normal lower right anatomical position, However, it can twist and shift due to abnormal activities, sometimes even beyond the midline to the left, resulting in a series of symptoms of partial intestinal obstruction, which is called hyperkinetic cecum syndrome.
