Colon Polyp Clinical Trial
Official title:
Short-term Effects of Bowel Preparation on Gut Microbiome in Patients Undergoing Endoscopic Colon Polypectomy
To investigate the role of different types of laxatives (compounded polyethylene glycol electrolyte dispersions and compounded sodium pico-sulfate) on the composition, evolution and recovery of the gut microbiome of patients with colonic polyps undergoing bowel preparation.
Good and adequate bowel preparation is essential for colonoscopy, especially in patients requiring endoscopic treatment, and the role of bowel purgatives and their safety for patients has been extensively studied. There are several laxatives available in clinical practice, the most widely used being electrolyte-supplemented polyethylene glycol (PEG) solutions, and other types of laxatives such as compound sodium picosulfate (SP) have been developed subsequently. When a large amount of laxative passes through the intestine, many microorganisms are removed from the intestine. Thus leading to significant changes in the composition of the intestinal microbiota during intestinal cleansing. There is no consensus on how gut cleansing affects the gut microbiome. There are no studies exploring whether there are differences in the effects of different types of laxatives on the human gut microbiome. In this study, focusing on patients diagnosed with colon polyps, the investigators explored the effects on the composition, evolution, recovery and functional pathways of the patients' gut microbiome after the use of different types of laxatives and endoscopic treatment. ;
