Role of preoperative gut microbiota on colorectal anastomotic leakage: preliminary results

The dysbiosis is defined as a disturbed symbiotic relationship between microbiota and the host and can cause a pro-inflammatory imbalance impairing the healing process at anastomotic level. The aim of this study is to detect, in fecal samples collected in the preoperative time, a peculiar microbiota composition that could predict the onset of colorectal anastomotic leakage.
