It’s very clear that, like mammography, in order to do a good sigmoidoscopy one needs training, consistent experience to maintain proficiency, current technology and good infection control. One also really needs to do a high volume operation. There was a very nice study done by Jim Lewis a few years ago showing how many sigmoidoscopies a year one would to do to break even based on Medicare payment. They determined it was at least 60 a year, and I think that’s probably a gross underestimate. We also need to standardize our reporting and our terminology so everyone can talk to each other in an efficient way. Something that they’re starting to do with breast cancer is go back to mammography centers and see how many of the patients they called positive really had breast cancer, and how many of the negatives showed up later in the registry having breast cancer. These are the kind of things that need to be applied to sigmoidoscopy. My view of this is that the model of performing sigmoidoscopy in doctors’ offices is wrong. It should be done like mammography where patients go to a center that’s high volume, equipped, has someone who knows how to do it, and who gets people in and out and can do ten or twelve in a morning.
