In recent years, a second pathway for colonic carcinogenesis, distinct from the adenomatous
pathway, has been explored. This is referred to as serrated pathway and includes three …

Background and Aims Appropriate colonoscopy withdrawal times for individual colonic
segments are not well known. The relationship between withdrawal time and adenoma …
