Abdominal tuberculosis: the surgical perspective.

The increasing incidence of pulmonary tuberculosis (TB) has led many to predict a corresponding increase in abdominal TB. This study reports the incidence, presentation, and outcome of abdominal TB to elucidate factors that might assist the surgeon to treat this potentially curable disease. A retrospective review of patients diagnosed with tuberculosis between 1993 and 1995 was performed at two hospitals. Diagnosis of abdominal TB was based on acid fast bacilli on tissue stains and/or culture. Seven patients were diagnosed with abdominal TB. Two patients were HIV positive; six were recent immigrants. Abdominal pain, fever, and significant weight loss were the most common symptoms. All preoperative radiologic tests failed to demonstrate findings suggestive of TB. All patients were brought to operation. Indications included perforated viscus (2), acute abdomen (1), small bowel obstruction (1), colocutaneous fistula (1), pelvic neoplasm (1), and biliary colic (1). Abdominal TB was either diagnosed or suspected intraoperatively in six patients. Postoperative anti-TB chemotherapy was promptly instituted. Although abdominal TB can be cured medically if treated early enough, the nonspecific presentation delays diagnosis in the majority of cases. Diagnosis of abdominal TB can be made or at least highly suspected intraoperatively such that anti-TB medications can be initiated promptly. Appropriate surgical therapy and prompt initiation of anti-tuberculosis medications can successfully treat abdominal TB.
