Colorectal Polypectomy Upon Insertion And Withdrawal Or Upon Withdrawal Only?

"Endoscopic procedures:~All polypectomies in the study groups were performed using the same techniques as in the standard care of non-study patients, using snare loops, hot biopsy forceps, with and without submucosal injection of saline/epinephrine. Polyps larger than 3 mm were removed by snare, polyps smaller than 4 mm were removed by cold biopsy. There were no differences upon insertion or withdrawal.~The endoscopist removed all visible polyps instantly regardless whether advancing the instrument to the cecum or pulling back."

There were no differences upon insertion or withdrawal.~The endoscopist advanced the endoscope to the cecum without removing polyps. Upon withdrawal, all visible polyps were removed successively by standard techniques."
