Summary
Arteriomesenteric duodenal occlusion can be linked to Strongyloides stercoralis infection. This curable parasitic infection should be considered in patients with this rare condition.
Area of Science:
- Gastroenterology
- Parasitology
- Vascular Surgery
Background:
- Arteriomesenteric occlusion of the distal duodenum is a rare condition often associated with anatomical changes that narrow the angle between the aorta and superior mesenteric artery.
- Clinical presentations can be diverse, necessitating a broad differential diagnosis.
Observation:
- This report describes two cases of arteriomesenteric duodenal occlusion.
- Both patients had a concurrent infection with Strongyloides stercoralis, a parasitic nematode.
Findings:
- In one patient, significant weight loss and resultant visceroptosis were identified as the primary mechanism leading to duodenal compression.
- In the second patient, engorgement of the superior mesenteric vessels was the predominant factor contributing to the occlusion.
Implications:
- Strongyloidiasis, despite being a treatable parasitic infection, should be included in the differential diagnosis for patients presenting with arteriomesenteric duodenal occlusion.
- Early diagnosis and treatment of Strongyloidiasis may prevent or resolve arteriomesenteric duodenal occlusion.
