Study on the Correlation Between Serum and Fecal Sialic Acid Levels and Tumor Characteristics as Well as Postoperative Anastomotic Leakage in Patients With Colorectal Tumors

Sponsor: Xiaolong Li

Summary

This is a Single-center bidirectional cohort study combined with prospective sample analysis conducted by the Department of General Surgery at the Second Affiliated Hospital of Army Medical University (Xinqiao Hospital). The purpose of this study was to retrospectively collect the preoperative serum sialic acid content and postoperative pathological data of colorectal cancer patients in our hospital's medical order system (including tumor size and stage, etc.) and anastomotic leakage, and analyze the correlation between serum sialic acid content and pathological characteristics of tumor and the correlation between anastomotic leakage; and further collect the feces of colorectal cancer patients in our hospital for 16S microbiome sequencing, and detect their sialic acid content, and observe the relationship between fecal sialic acid content and tumor size and stage; Intestinal flora composition and postoperative anastomotic leakage correlation, provide a new theoretical basis for the prevention and treatment of postoperative anastomotic malhealing.
