Abdominal Tuberculosis in Children: Challenges, Uncertainty, and Confusion

Abstract

Abstract The diagnosis of abdominal tuberculosis (TB) is challenging, and the prevalence of abdominal TB in children is likely underestimated. It may present with nonspecific abdominal symptoms and signs, but children who present with pulmonary TB may have additional abdominal subclinical involvement. Diagnosis is specifically challenging because none of the available diagnostic tools provide adequate sensitivity and specificity. In this review, we summarize the best available evidence on abdominal TB in children, covering the epidemiology, pathogenesis, clinical presentation, diagnosis, and treatment. We propose a diagnostic approach that could be followed for symptomatic children. We believe that a combination of investigations could be useful to both aid diagnosis and define the extent of the disease, and we propose that abdominal ultrasound should be used more frequently in children with possible TB and any abdominal symptoms. This neglected disease has received little attention to date, and further research is warranted.
