Anastomotic leak (AL) is a serious post-operative complication in colorectal surgery. It can lead to devastating morbidity and mortality. Clinicians usually depend on a combination of clinical, biochemical and radiological findings to diagnose this problem. In our article, we tried to look if electrolyte disturbances could be indicators for intra-abdominal sepsis due to AL. Systematic review of the literature identifies a potential correlation between electrolyte alterations and AL in digestive surgery. The following databases were searched: PubMed, EMBASE and MIDLINE. The review adhered to the PRISMA statement for systematic review. Our literature search did not identify any articles linking any electrolyte disturbances-except for hyponatremia-to AL. Pathophysiology of these electrolyte disturbances does not seem to be linked to AL, except for hyponatremia which might be explained. Our review included 442 patients with intra-abdominal sepsis and 1133 controls. The mean specificity of hyponatremia being associated with intra-abdominal sepsis is 86%, whereas mean sensitivity is 28%. Hyponatremia seems to be a significant and clinically relevant marker for of intra-abdominal sepsis and AL.
