Core Tip
Core Tip: This systematic review and meta-analysis of thirty-six studies found no consistent differences between non-diversion and surgical fecal diversion (SFD) in mortality, intensive care unit admission or the number of surgical procedures. Hospital length of stay showed significant heterogeneity, with sensitivity analysis favoring non-diversion after exclusion of one outlier study. Overall certainty of evidence was very low, mainly due to confounding by indication and inconsistent group definitions. These findings do not demonstrate a clear overall advantage of routine SFD and support the need for standardized criteria and prospective studies in Perineal necrotizing soft tissue infections.
