Abdominal tuberculosis: the problem of diagnostic delay

Area of Science:

• Gastroenterology
• Infectious Diseases
• Surgical Pathology

Background:

• Abdominal tuberculosis diagnosis presents significant challenges, often leading to delays.
• Current diagnostic methods like the Mantoux test and ascitic fluid cultures have limitations in early detection.

Purpose of the Study:

• To evaluate the efficacy of different diagnostic methods for abdominal tuberculosis.
• To identify the most reliable approach for timely diagnosis and minimize delays.

Main Methods:

• An audit study was conducted comparing diagnostic techniques.
• Methods assessed included Mantoux test, ascitic fluid culture, and surgical biopsy (laparoscopy/laparotomy) with Ziel-Nielson staining and tissue culture.

Main Results:

• The Mantoux test and ascitic fluid cultures did not consistently provide immediate diagnosis.
• Laparoscopy/laparotomy with Ziel-Nielson staining and tissue biopsy culture definitively confirmed abdominal tuberculosis in all cases.

Conclusions:

• Surgical biopsy, specifically laparoscopy/laparotomy with histological examination and culture, is the gold standard for diagnosing abdominal tuberculosis.
• Biopsy should be considered the primary investigation for patients with suspected abdominal tuberculosis to expedite diagnosis.
