Anastomotic leak occurs independently from microbiota shifts associated with surgical bowel preparation.

ABSTRACT: Following bowel surgery, infectious complications, including anastomotic leak (AL), remain major sources of morbidity and mortality. Bowel preparation is often administered with the assumption that gut decontamination reduces post-surgical complications. In this study, we tested this hypothesis using a murine model of colon surgery. The mice were fed either regular chow or a high-fat, high-sugar Western diet. The day before surgery, the mice received one of four interventions: water (control), mechanical bowel preparation (MBP), oral antibiotics (OA), or both MBP and OA. We found no differences in the rates of AL among the experimental groups, and diet did not appear to affect the outcomes. Exploratory analyses showed changes in the gut microbiome consistent with the different treatments,
