Bacterial shift and resistance pattern in pancreatic head resections after selective decontamination of the digestive tract - a propensity score-matched analysis.

Background: Pancreatic head resection is associated with postoperative morbidity, primarily because of infectious complications. The microbiota in these infections is crucial, and selective decontamination of the digestive tract (SDD) aims to mitigate this risk by targeting pathogenic organisms while preserving beneficial flora. This study aimed to determine the effect of SDD on bacterial shifts and resistance patterns in pancreatic head resection.
