ABSTRACT
INTRODUCTION: Diagnosing peritoneal tuberculosis is challenging due to unspecific clinical manifestations, particularly in immunocompromised patients with HIV/AIDS and tuberculosis infections. PRESENTATION OF CASE: An Indonesian man, 26-years-old, complained of mid-abdominal colic and constipation. The patient's present state exhibited symptoms of weakness and paleness, oral candidiasis, a bloated abdomen, palpable discomfort, and shifting dullness. The ascitic fluid analysis showed increased ADA (709 U/L), and detected Mycobacterium tuberculosis using GeneXpert MTB/RIF. Radiographic examination from abdominal x-ray and CT scan revealed a small bowel obstruction. He received intestinal decompression, pain control, intravenous fluid resuscitation, and correction of electrolyte imbalance for small bowel obstruction without any indication for surgical intervention. He also receive first-line ATD for 2 months during intensive phase and 4 months for continuous phase. After a period of 2 weeks following the ATD administration, the patient began taking ARV medication on a daily basis. He showed a good prognosis 6 months following. DISCUSSION: The diagnosis of peritoneal tuberculosis is challenging due to its unspecific manifestation and some cases are identified when complications such as small bowel obstruction appear. The ADA test and GenExpert MTB/RIF are useful instruments for promptly diagnosing tuberculosis. It is suggested to use ARV treatment in individuals with HIV/AIDS who have peritoneal tuberculosis, starting 2 weeks following ATD treatments. CONCLUSION: Peritoneal tuberculosis with small bowel obstruction and HIV/AIDS infection is a rare case in which early diagnosis and monitoring play an important role in successful treatment.
