[Jejuno-ileal volvulus, a rare cause of intestinal obstruction].

Volvulus of the small bowel without predisposing anatomical defects is a rare cause of acute intestinal obstruction in the Western world, and its incidence is decreasing in Europe and America, although it is common in others parts of the world. The causes of primary volvulus of the small bowel and the mechanism of rotation of the entire root of the mesentery remain unexplained. Several anatomical and dietary factors have been implicated. This theory requires strong peristalsis, tense, firm abdominal muscles and feeding pattern of very bulky meals taken at long intervals. In the present case, a large quantity of bulky poorly digested food consumed previously, and strong abdominal muscles are in keeping with the above theory.
