Summary
This study presents two cases of duodenal tuberculosis, a rare condition. Diagnosis was confirmed through endoscopy and biopsy, highlighting the importance of these methods for identifying gastrointestinal tuberculosis.
Area of Science:
- Gastroenterology
- Infectious Diseases
- Microbiology
Background:
- Duodenal tuberculosis is a rare manifestation of Mycobacterium tuberculosis infection.
- It often presents with non-specific symptoms, making diagnosis challenging.
- Recent trends show a shift in the location of duodenal lesions and diagnostic methods.
Observation:
- Two cases of duodenal tuberculosis are presented: one in a post-gastrectomy patient with disseminated TB, and another in a patient with pulmonary TB and diabetes mellitus.
- Diagnostic methods included upper gastrointestinal endoscopy, histopathology (granulomatous inflammation, acid-fast bacilli), and Mycobacterium tuberculosis cultures.
- Case 1 showed duodenal and colonic TB, while Case 2 had isolated duodenal involvement.
Findings:
- Endoscopic and histopathological findings confirmed duodenal tuberculosis in both patients.
- Mycobacterium tuberculosis was identified through smear, culture, and PCR.
- A review of Japanese literature since 1988 indicates a shift in diagnostic approaches and lesion location.
Implications:
- Endoscopic examination is crucial for diagnosing duodenal tuberculosis, particularly in recent cases located in the descending duodenum.
- Understanding the changing patterns of duodenal TB diagnosis and location is important for clinicians.
- Early and accurate diagnosis of duodenal TB can guide appropriate treatment and improve patient outcomes.
