Summary
Gastrointestinal tuberculosis can mimic other digestive issues. This study highlights four cases of isolated duodenal tuberculosis, emphasizing the diagnostic challenges and the importance of surgical biopsy for accurate identification.
Area of Science:
- Gastroenterology
- Infectious Diseases
- Surgical Pathology
Background:
- Gastrointestinal tuberculosis (GITB) remains a significant health concern, particularly in developing nations.
- GITB often presents with non-specific symptoms, mimicking common gastrointestinal (GI) disorders.
- Isolated proximal duodenal tuberculosis is rare, posing diagnostic challenges.
Purpose of the Study:
- To report four cases of isolated proximal duodenal tuberculosis.
- To illustrate the diverse clinical presentations that can obscure diagnosis.
- To emphasize the limitations of conventional diagnostic methods and highlight the utility of surgical biopsy.
Main Methods:
- Retrospective case series analysis of four patients with isolated proximal duodenal tuberculosis.
- Review of clinical presentations, diagnostic investigations (including radiology and endoscopy), and treatment outcomes.
- Emphasis on histopathological findings from surgical biopsies.
Main Results:
- All four cases presented with symptoms mimicking peptic ulcer disease or gastric outlet obstruction.
- One patient exhibited a pyeloduodenal fistula, a rare complication.
- Clinical evaluation, radiology, and endoscopy showed limitations in definitively diagnosing duodenal tuberculosis.
- Surgical biopsy provided the definitive diagnosis in all cases.
Conclusions:
- Isolated proximal duodenal tuberculosis can present insidiously, mimicking other GI conditions.
- Diagnostic modalities like endoscopy and radiology have limitations in detecting this specific form of GITB.
- Surgical biopsy remains a crucial tool for the accurate diagnosis of duodenal tuberculosis, especially in endemic areas.
