Abdominal ultrasonographic findings in typhoid fever: a comparison between typhoid patients and those with non-typhoidal Salmonella and Campylobacter jejuni enterocolitis.
Typhoid fever is a major health problem in many developing countries and its clinical features are similar to other types of bacterial enterocolitis. Definitive diagnosis by blood culture requires several days and is often unfeasible to perform in developing countries. More efficient and rapid diagnostic methods for typhoid are needed. We compared the pathological changes in the bowel and adjacent tissues of patients having typhoid fever with those having bacterial enterocolitis using ultrasonography. A characteristic of patients with non-typhoidal Salmonella and Campylobacter jejuni enterocolitis was mural thickening of the terminal ileum; only mild mural swelling or no swelling was observed in patients with typhoid fever. Mesenteric lymph nodes in patients with typhoid fever were significantly more enlarged compared to patients with other types of bacterial enterocolitis. Our findings suggest typhoid fever is not fundamentally an enteric disease but rather resembles mesenteric lymphadenopathy and ultrasound is a promising modality for diagnosing typhoid fever in developing countries.
