The goal of this observational study is to learn about the molecular characteristics of colorectal polyps in patients with metabolic dysfunction-associated steatohepatitis (MASH) compared to individuals without fatty liver, and to identify potential transcriptomic biomarkers for high-risk polyps. The main questions it aims to answer are: What are the key gene expression differences in adenomatous polyps between MASH patients and non-fatty liver individuals? Can specific high-risk transcriptional molecules in plasma and polyp tissue serve as biomarkers for MASH-related colorectal polyps? Participants already scheduled for colonoscopic polypectomy as part of their routine care will provide a small portion of their polyp tissue, residual plasma from standard blood tests, and allow use of their stored pathological slides for research; they will also be followed up every six months.
