Summary
This study highlights Campylobacter enterocolitis as a cause of melena without typical infectious symptoms. Early diagnosis using stool microscopy, culture, and endoscopy is crucial for effective treatment and patient recovery.
Area of Science:
- Gastroenterology
- Infectious Diseases
- Microbiology
Background:
- Melena, or the passage of dark blood per rectum, can present without typical infectious enterocolitis symptoms.
- Campylobacter enterocolitis is a common bacterial infection that can affect the gastrointestinal tract.
Observation:
- A 38-year-old male presented with recurrent melena, initially showing no abnormalities on upper endoscopy.
- Proctoscopy revealed significant rectal blood, and colonoscopy identified inflammation and coagulation from the splenic flexure to the rectum.
- Stool microscopy suggested Campylobacter enterocolitis, leading to erythromycin treatment.
Findings:
- The patient's condition improved following antibiotic treatment, confirmed by a repeat colonoscopy showing reduced mucosal changes.
- Final diagnosis of Campylobacter enterocolitis was established through stool culture.
- Bacteriological stool examination combined with endoscopy proved effective in diagnosing melena in this case.
Implications:
- This case underscores the importance of considering infectious etiologies like Campylobacter enterocolitis in patients presenting with melena, even without overt signs of infectious enterocolitis.
- The diagnostic utility of combining stool analysis with endoscopic findings is highlighted for managing such cases.
- Prompt diagnosis and treatment are essential for favorable outcomes in Campylobacter enterocolitis presenting with melena.
