How I do colonoscopy

Anatomy is the single most important and challenging aspect of colonoscopic intubation. The rectum lies in the hollow of the sacrum. The sigmoid is a spiral structure that continues over the bladder anteriorly just above the symphysis pubis and then continues its twist to become the descending colon (posterior). This spiral concept is important in every phase of the colonoscopic examination.
