Succoring the challenging acute mesenteric ischemia: Feasibility of lactate dehydrogenase for evaluation of intestinal necrosis extension and mortality
Summary
Background
Acute mesenteric ischemia is a lethal challenging pathology for surgeons in the emergency department due to its ambiguous clinical presentation and lack of early diagnostic markers. Serum lactate is considered a relevant biomarker in terms of bowel necrosis length and mortality prediction. Nevertheless, its association has been poorly studied. Hence, we evaluated the relation between serum lactate admission levels, bowel necrosis extension, and mortality in patients with acute mesenteric ischemia.
Methods
A Retrospective cross-sectional study with a prospective database was conducted, including patients over 18 years old with mesenteric ischemia that required surgical management between January 2012 and December 2018. We describe the association between serum lactate admission levels with bowel necrosis length and mortality in patients with acute mesenteric ischemia.
Results
74 patients presented with acute mesenteric ischemia, 44 males and 30 females. Mean age was 73.5 ± 10.7 years old. Significant association between serum lactate admission levels and mortality was found (ROC cut-value of 3.8 mmol/l, 81.0% sensibility and 76% specificity, LR+3.41 (95%CI 1.57, 7.40), LR- 0.25 (95%CI 0.13–0.45))(P.001). Nonetheless no statistically significant association was found between serum lactate admission levels and bowel necrosis length (ρ = 0.195,95%CI -0.046, −0.436, P > .99). As post hoc analysis, a classification and regression tree on mortality was fitted.
Conclusions
Early diagnosis, prognosis and management of mesenteric ischemia is vital given its high morbidity and mortality. Serum lactate admission levels can be considered as a useful prognostic tool in terms of mortality in patients with acute mesenteric ischemia.
