Recent reports 1-6,29 indicate that diverticula of the jejunum and ileum other than Meckel's diverticulum are not as rare as has generally been thought. Forty-five patients with diverticula of the mesenteric small intestine have been studied at The New York Hospital in an effort to correlate the clinical and radiographic patterns of this condition. Twenty-one cases of jejunal diverticula were previously reported from this hospital and surgical aspects and operative procedures discussed.29 Meckel's diverticulum has been excluded from this group, since it represents a specific congenital diverticulum of the ileum as a remnant of the omphalomesenteric (vitelline) duct.
Diverticula of the jejunum and ileum have been less often recognized radiographically than at autopsy, with incidence reports varying from 0.3% to 1.3% of the hospital population. Special postmortem studies of the small intestine, including air insufflation, have yielded the higher incidence figures.7 Radiographic study of the small intestine is
