Abstract:
Gastrointestinal bleeding caused by a duodenocaval fistula is rare, diagnostically challenging, and associated with a high mortality rate. We describe the case of a patient with polymicrobial fungemia and fatal gastrointestinal bleeding related to a duodenocaval fistula caused by peptic ulcer. Polymicrobial fungemia, which has not previously been associated with this condition, raises the possibility of candidal endocarditis.
Insights
A rare duodenocaval fistula caused fatal gastrointestinal bleeding in a patient with polymicrobial fungemia. This association suggests a potential link to candidal endocarditis, highlighting diagnostic challenges and high mortality risks.
Area of Science:
- Gastroenterology
- Infectious Diseases
- Vascular Surgery
Background:
- Duodenocaval fistulas are rare but life-threatening complications, often stemming from peptic ulcers.
- Gastrointestinal bleeding from these fistulas presents significant diagnostic and management challenges.
- High mortality rates underscore the severity of this condition.
Observation:
- A case is presented of a patient experiencing fatal gastrointestinal bleeding due to a duodenocaval fistula.
- The patient also presented with polymicrobial fungemia, a condition not previously documented with duodenocaval fistulas.
- The fistula was attributed to an underlying peptic ulcer.
Findings:
- Polymicrobial fungemia was identified in a patient with a duodenocaval fistula and gastrointestinal bleeding.
- This represents a novel association between fungemia and duodenocaval fistula formation.
- The findings suggest a potential, previously unrecognized pathway involving fungal infections.
Implications:
- The presence of polymicrobial fungemia raises the possibility of candidal endocarditis as a contributing or causative factor.
- This case broadens the differential diagnosis for gastrointestinal bleeding in critically ill patients.
- Further investigation is warranted to understand the role of fungal infections in the development of duodenocaval fistulas.

In the antrum region, G cells secrete the gastrin hormone that binds to gastrin-cholecystokinin-B (CCK2) receptors on parietal and enterochromaffin-like (ECL) cells in the fundic glands. Simultaneously, the vagus nerve releases acetylcholine, which binds to M3...

An acute ulcer, marked by superficial erosion and minimal inflammation, swiftly resolves upon identifying and addressing the underlying cause. In contrast, a chronic ulcer persists, potentially eroding through the muscular wall and forming fibrous tissue.
