Colonoscopy is a cancer screening method with high usage in United States clinical endoscopic operations. When proper bowel preparation is done prior to a colonoscopy procedure, there has been documented beneficial impacts with reduces successive procedures and lower cases of cancer development and resultant mortalities. However, thorough cleaning during preparation hinders effective polyp detection and recommendations include low-residue diet and combining with split-dose regimens. In context to anesthetic use in colonoscopy, studies reveal increased medical risks after operation such as stroke, hemorrhage, pain and perforation. More attributed risks of anesthetic use in coloscopy covers cardiopulmonary aspects of ventilation and oxygen concentration thus affecting patient safety.
Colonoscope insertion requires high intensive skills and technological guidance in ensuring effectiveness. When anesthetics are absent in a procedure, water-aided methods and application of carbon dioxide insufflation are used to minimize pain and associated discomfort. Adenoma detection rate (ADR) is a measure of colonoscopy success whose standards are 30% and above scores in men while women rates are recommended at 20 % or more ( Rastogi & Wani, 2017) . Withdrawal period is the determinant for ADR performance with longer times being associated with higher metric scores. Therefore, it is important to closely monitor and label in an average withdrawal period of six minutes as recommended.

Proper diagnosis of serrated polyps especially through CT scans has been associated with successful colonoscopy and cancer detection. Moreover, it is important to keep relevant to PIVI guidelines through effective training and experience in ensuring endoscopists are highly competent and possess quality knowledge in related fields. However, dynamics of the profession are changing fast due to technological advancements in diagnostic and management procedures such as push-button optical magnification which create efficiency and quality performance. Therefore, in assessing tools and methods for endoscopy, it is important to consider procedure effectiveness, cost-effectiveness and patient safety using technological tools and quality knowledge.
