Tuberculosis in the belly: A review of forty-six cases involving the gastrointestinal tract and peritoneum

Background: Abdominal tuberculosis has varied presentation and can be confused with other conditions. Methods: We report our experience with 46 patients. Charts of patients managed during 1984-97 were reviewed. Results: Fifty-two percent were women and mean age was 46 years. Presenting symptoms were as follows: fever 70%; abdominal pain 70%: weight loss 68%: abdominal swelling 67%: change in bowel habit 39%: anorexia 30%: and sweating 30%. Common physical signs were as follows: fever 73%; ascites 61%; abdominal mass 13%. and doughy abdomen 9%. Thirty percent of patients either gave past history of TB or presented with active TB of other sites. TB skin test was positive in only 27% of patients. CT scans of abdomen were abnormal in 80%. showing ascites. peritoneal lesions or enlarged nodes. Ascitic fluid was diagnostic for TB on smear/culture in 33%. Peritoneal biopsy was performed by laparoscopy or laparotomy in 61%. It was positive for ganulomas in 97% and for smear/culture in 68%, Forty-two patients recovered after receiving anti-TB therapy for 9-12 months. Four patients died. One died within 1 month of initiation of therapy due to extensive TB, and death in the other 3 was due to unrelated causes. Conclusion: Abdominal TB should be suspected in patients with fever, abdominal pain and ascites. This condition carries good prognosis if promptly diagnosed and treated.
