1Department of Internal Medicine, Gifu Red Cross Hospital.
Summary
Severe amebic colitis can lead to rare complications like colonic strictures, even after successful treatment with metronidazole. Prompt diagnosis is crucial for managing this parasitic infection and preventing severe outcomes.
Area of Science:
- Gastroenterology
- Infectious Diseases
- Parasitology
Background:
- Amebic colitis, caused by Entamoeba histolytica, is a significant cause of infectious diarrhea worldwide.
- Complications of amebic colitis can include toxic megacolon, perforation, and hemorrhage, necessitating prompt medical intervention.
Observation:
- A 53-year-old male presented with acute diarrhea, abdominal pain, and fever.
- Abdominal imaging revealed colonic dilatation, while sigmoidoscopy showed aphthoid erosions and ulcers.
- Biopsies confirmed Entamoeba histolytica trophozoites.
Findings:
- The patient received oral metronidazole, leading to rapid clinical improvement.
- Post-treatment investigations identified multiple cicatricial strictures in the colon.
- These strictures represent a rare but significant long-term complication of amebic colitis.
Implications:
- Severe amebic colitis should be considered in the differential diagnosis of patients presenting with severe diarrhea and fever.
- Cicatricial strictures, though rare, can occur even with timely medical intervention.
- Understanding these potential complications is vital for comprehensive patient management and follow-up.
