Jejunal diverticulosis.

Diverticulosis of the jejunum is an uncommon condition. We found four patients with such diverticula among 40,341 hospital admissions. All four patients presented with acute volvulus of the small bowel. It is suggested that the diverticula bearing segment becomes heavier due to the diverticula and the semisolid jejunal contents consisting of roughage, millet and cereals in the staple diet of our patients. Both factors contribute to small bowel volvulus. Jejunal diverticula may be missed because they are buried between the leaves of mesentery or adherent loops of jejunum. With a patient has vague abdominal symptoms, the possibility of jejunal diverticula should be considered.
