Cell-free deoxyribonucleic acid as a prognostic marker of bowel ischemia in patients with small bowel obstruction

Surgeons currently rely on imprecise clinical parameters, including degree of pain, abdominal tenderness, leukocytosis etc to decide when operative intervention is needed. The association of cell-free deoxyribonucleic acid with small bowel obstruction, ischemia, and recovery supports our hypothesis and suggests that this biomarker is a potential surrogate of small bowel perfusion.
