Brief Summary

Observational study The aim of this observational study is to investigate the effect of water temperature used during pre-colonoscopy bowel preparation on the quality of bowel cleansing. The primary research question to be addressed is as follows: Which water temperature results in better bowel cleansing quality? For this purpose, patients will be divided into two groups based on the use of warm water or cold water, and the quality of bowel preparation will be compared between the groups.
