ABSTRACT
Examination of the lower gastrointestinal tract has evolved in the past 50 years with the advent of fiber-optic colonoscopy that allows for accurate and safe visualization of mucosal lesions to become the optimal method for both the diagnosis and treatment of the rectum, colon, and distal aspect of the terminal ileum. With guidelines endorsing colonoscopy as a screening option for colorectal cancer, the demand and need for colonoscopy will increase with the aging population. Furthermore, it highlights the importance of quality and standardization of colonoscopy as a screening procedure, which has been developed by the joint American Society of Gastrointestinal Endoscopy and American College of Gastroenterology Taskforce on Quality in Endoscopy.22
