Appendicular tuberculosis: review of 155 published cases and a report of two cases.

PURPOSE: This paper provides an overview of the literature on appendicular tuberculosis (ATB) between 1909 and 2010.

METHODS: We present two cases of primary ATB and a literature review of studies on ATB published in English and accessed via the Pubmed and Google Scholar databases.

RESULTS: One hundred fifty-five published cases of ATB were reviewed, and two patients with primary ATB, treated and followed in our clinic, were reported. The age range of the patients (62 females, 60 males and 33 with unnoted gender) was between 2 and 60 years, with a mean age of 27.1 ± 10.6 years. Of the patients who had applied to hospital, 59 had acute right lower quadrant pain, 46 had recurrent right lower quadrant pain, 19 had generalized pain, and 10 had chronic abdominal symptoms suggestive of subacute intestinal obstruction, while 47 patients were operated on with a diagnosis of acute appendicitis, 24 with recurrent appendicitis, 19 with TB peritonitis, 14 with mass in the right lower quadrant, 13 with subacute intestinal obstruction, and 7 with ATB. While appendectomy was not performed on 4 patients, one or more of the following procedures were done in the other 151 cases: appendectomy, hemicolectomy, ileocecal resection, or cecectomy. Different anti-tubercular treatment regimens with durations varying from 3 weeks to 18 months were applied to 60 patients. During the follow-up period of 3 weeks to 15 years, mortality occurred in 14 patients, sinus in five, and fistula in one patient. Secondary ATB was detected in 86 patients, primary ATB in 50, and no differential diagnosis could be made in 19 cases.

CONCLUSIONS: Tuberculosis is a systemic disease with localized manifestations; therefore, anti-TB therapy must be initiated in any patient whose pathologic specimen reveals tuberculosis.
