Show abstract
Anastomotic leakage (AL) is a frequent and potentially life-threatening postoperative complication in patients undergoing colorectal surgery with a multifactorial yet unknown pathophysiology. In the present study, we aimed to unravel AL etiology and intestinal anastomotic healing (AH) physiology focusing on both host epithelial and gut microbial components. We make use of patients-related samples and two high throughput next generation sequencing analysis approaches, including anastomotic tissue-associated bulk RNA sequencing and preoperative fecal 16S rRNA gene sequencing. We find that in the absence of host epithelial gene expression differences, the preoperative fecal microbiota of patients who undergo colorectal resection with successful AH differs in the group of patients who develop AL in the abundance of Prevotella and suggests a potential beneficial role of Prevotella that may prove useful as predictive biomarker for AH.

"Similar papers" are the closest papers from that journal in the model's embedding space. They show what the match is built on, but the ranking comes mostly from a classifier over the whole training set, not from these examples alone.
