Strongyloides stercoralis infection presenting as a surgical diagnosis, a rare but important consideration: Case series of two patients.

INTRODUCTION

Strongyloides stercoralis (S. stercoralis), is a parasitic helminth with variable gastrointestinal symptoms that can mimic inflammatory bowel disease or malignancy. Diagnosis is often delayed due to nonspecific presentation and low test sensitivity, especially in non-endemic areas.

METHODS

We reviewed two cases of S. stercoralis infection presenting as chronic colitis. Clinical, endoscopic, and histologic findings were analyzed, and diagnosis was confirmed via serology testing.

RESULTS

Both patients presented with chronic abdominal pain and colitis on image test. Serological tests revealed immune responses consistent with S. stercoralis infection. One patient had a history of travel to an endemic area; the other had chronic alcohol use. Symptoms resolved with antiparasitic therapy.

CONCLUSION

S. stercoralis infection can produce chronic colitis and lead to misdiagnosis. Awareness of risk factors and histologic features is essential to avoid unnecessary surgical intervention.
