[The role of biomarkers in the diagnostics of acute mesenteric ischemia].

Acute mesenteric ischemia is a severe and challenging disease. Unspecific symptoms in the initial phase make a fast diagnosis difficult although it is of major importance to protect patients from irreversible ischemia, extended bowel resection, sepsis and death in the late phase. In contrast to troponin as an early biomarker for cardiac ischemia, a reliable biomarker for acute intestinal ischemia has not yet been identified in the current literature and clinical practice. This would allow the early identification of these critically ill patients in the initial reversible phase of acute intestinal ischemia.This review highlights the pathophysiology, epidemiology and clinical findings of acute mesenteric ischemia and gives an overview of biomarkers which have been investigated in mesenteric ischemia with a special focus on lactate, which is the only parameter routinely used in the diagnostic setting of acute mesenteric ischemia.
