You will be asked to require one among several bowel preparations as directed by your provider. it’s been proven that split dosing (dividing the preparation medications into two separate timed doses, typically the evening before very early the day of the exam) achieves the very best success rate inadequate clearing of the colon. It can’t be over-emphasized that regardless of what prep you use; all of them are work the simplest once you drink many clear liquids.

Inexperienced endoscopists or those with poor technique or too rapid exam

More experienced endoscopists miss fewer lesions than trainees and fewer experienced endoscopists even when the time of withdrawal is equal. The accepted standard for withdrawal time is now six minutes or more. most exams report withdrawal time and lots of endoscopists have known withdrawal time averages correlated with their polyp detection rate. Subpar withdrawal times and polyp detection rates would be an indicator that an endoscopist’s technique is below that generally accepted within peers. Poor endoscopy technique is said to the training of the endoscopist also as a number of procedures performed within the past. because the number of procedures increases the skill of the endoscopist nearly always improves
