I have read with great interest the article by Dr. Kolber and
applauded him for providing his patients with important screening
alternative. I am too a Rural physician that performs endoscopies and have
gone through a training in endoscopy to provide safe and quality service.
While current North American recommendations do not support
population screening with colonoscopy but support FOBT screening (less
expensive and less sensitive alternative), in United States patients are
being screened more often with colonoscopy then in Canada.
Although colonoscopy was available for a long time there were no
large RCTs done to compare colonoscopy to FOBTs screening. Multiple small
studies were conducted that demonstrated benefits for detections adenomas
and cancers. Current evidence show that the sensitivity for detection of cancer
by FOBT is about 50% while by colonoscopy is over 90% (1). Knowing the
information it is difficult to deny one to have colonoscopy done as an
alternative.
Recently, I was pleased to see a publication for patients on cancer
screening by Cancer Care Ontario that lists colonoscopy as one of the
options for screening. This provides patients with more educated
understanding of their options.
In Canada, one of the concerns is a cost and provider availability.
While constantly improving patients care, we should look forward and
assess our resources especially in rural areas.
I believe that we have to broaden training of rural physicians to
provide comprehensive care including endoscopies to improve health care in
rural areas. This will provide better screening for selected patients and
will shorten wait time to diagnosis of colorectal cancer that is a second
and a third cause of mortality from malignancies among males and females
in Canada, respectively.
