Summary
Nonocclusive mesenteric ischemia (NOMI) presents with vague symptoms, delaying diagnosis and leading to poor outcomes. Early detection is crucial, as delayed diagnosis necessitates extensive bowel resection, increasing morbidity and mortality.
Area of Science:
- Gastroenterology
- Vascular Surgery
- Critical Care Medicine
Background:
- Nonocclusive mesenteric ischemia (NOMI) is often reported with favorable outcomes.
- However, clinical experience suggests NOMI may have higher morbidity and mortality.
- This study examines institutional experience with NOMI.
Purpose of the Study:
- To analyze the clinical course and outcomes of patients diagnosed with NOMI.
- To identify factors associated with delayed diagnosis and poor prognosis in NOMI.
Main Methods:
- Retrospective chart review of patients with acute mesenteric ischemia between 1979 and 1992.
- Identification of patients meeting NOMI criteria.
- Classification of patients into early and late presenters based on diagnosis timing.
Main Results:
- 13 patients (12%) met NOMI criteria.
- Early presenters (n=5) were younger women with vague symptoms and delayed diagnosis.
- Late presenters (n=7) were older, had risk factors, and presented with established bowel infarction.
Conclusions:
- Early diagnosis of NOMI is challenging due to vague symptoms and diverse patient risk factors.
- Delayed diagnosis significantly increases the likelihood of bowel resection.
- Bowel resection in advanced NOMI is associated with high morbidity and mortality.
