A power flush also makes for a marked improvement in visualiza-
tion, says Gregory G. Ginsberg, MD, a professor and executive direc-
tor of endoscopic services at the University of Pennsylvania Perelman
School of Medicine in Philadelphia. Most newer model scopes include
forward flush capabilities, he says. Irrigation systems that thread
through a scope's working channel are also available. Not only is irri-
gation essential for clearing residual matter, bleeding or other
obstructions, "it can also provide lubrication in the colon, decreasing
tactile resistance and easing the passage of the scope," says Dr.
Ginsberg.
Shared goal
The newest enhancements fall into 2 areas: improved optics and smooth-
ing mechanical innovations. The approaches differ, but they all aim for
the same goal — better visualization of the entire colon surface.
