PRIMARY tuberculous enteritis is rare, but a significant number of patients with pulmonary tuberculosis develop secondary intestinal involvement. Blumberg found that 5 to 8% of patients with early pulmonary tuberculosis have roentgenographic evidence of involvement of the gastrointestinal tract, while in advanced cases the incidence is 70 to 80%.14 In cases studied at necropsy, the incidence reported by different authors ranges from 65 to 90%.4 The commonest site of involvement is the cecum, as 87% of patients with tuberculous enteritis have lesions in this area. The next commonest site is the ileum. The remainder of the colon, the jejunum, the appendix, sigmoid and rectum, duodenum, and stomach are involved in a decreasing order of frequency.13 These figures were obtained prior to the advent of the antituberculosis drugs, and no comparable figures are available at the present time for comparison. However, in all probability, the incidence is decreasing
