IN 1932, Crohn, Ginzburg and Oppenheimer1 first described the clinicopathologic entity which was called "terminal ileitis." Since then, many instances of the same pathologic process in all parts of the ileum and jejunum have caused modification of the term to "regional enteritis." Of the numerous cases reported, however, in only a few has the disease been limited to the jejunum. Harris, Bell and Brunn2 first described a case with the lesion wholly in the jejunum. Brown and Donald3 included in their 178 cases of regional enteritis 5 instances of primary jejunal lesions. W. R. Johnson4 reported a case with multiple diseased segments which were all confined to a few feet of jejunum and for which resection with end to side anastomosis was performed. H. N. Brewster5 also described an instance of localized obstructing jejunitis in a small section of bowel treated by resection and anastomosis.
