Intestinal tuberculosis: Case series of three patients

Abstract

BACKGROUND: Intestinal tuberculosis (ITB) is a fraction of extrapulmonary TB, and its diagnosis often pose a significant challenge due to nonspecific presentation. Several methods have been utilized to diagnosed ITB, including findings of specific inflammatory process on histopathological examination. We hereby report three cases of ITB that manifested as caecal and adnexal mass. CASE REPORT: First case, a 22-year-old male, presenting with abdominal pain, underwent exploratory laparotomy, biopsy, right hemicolectomy, and anastomosis end-to-side to the transverse ileocolical region due to partial ileus obstruction from caecal tumor. The second and third cases, a 27-year-old and 39-year-old females, both presenting with abdominal pain and distension, underwent exploratory laparotomy, adhesiolysis and biopsy. Histopathological examination in all three cases showed chronic granulomatous inflammation caused by TB. All three patients were diagnosed as ITB and received 6 months of anti-tuberculosis drug (ATD). DISCUSSION: Intestinal TB most commonly affected region is the ileocaecal, accounts for 64% of the incidence of gastrointestinal TB. The main reasons for the predilection of ileocaecal region are due to relatively longer faecal static, the abundant of lymphoid tissue, a neutral pH environment and absorptive transport mechanisms that allow swallowed mycobacterium to be absorbed. Intestinal TB may pose similar symptoms as those found in pulmonary TB, yet patients most commonly presenting with abdominal pain. Bacteriological signs and histopathological findings are gold standard for ITB diagnosis. Therapy for ITB includes pharmacological ATD and surgical therapy.
