The renaissance of abdominal tuberculosis

During the last decade, abdominal tuberculosis (TB) has experienced a renaissance. The number of cases diagnosed in Western European and North American countries has dramatically increased. The reasons for this are multiple and include the appearance of AIDS as a significant disorder and the increased morbidity of peoples across the world with the migration of many people from areas of high incidence of TB to the West. Recent epidemiological work is reviewed, and its relationship to these changes considered. The distribution of disease along the gastrointestinal tract and in the mesentery is discussed. The frequency of involvement at various sites and the clinical symptoms caused by the disease are reviewed. The need to diagnose abdominal TB in the 1990s is considered in detail in areas where the disease had previously been thought rare.
