7 papers tracking new advances in colonoscopy screening.
In recent weeks, a large number of studies on advances in colonoscopy have been published in the gastrointestinal society community and in gastrointestinal-related journals, including new regulatory issues, the latest validated data on cancer prevention, and meta-analyses on bowel preparation protocols. Medical Pulse has compiled the key points of this literature below for the benefit of our readers.
1. CMS proposes to reduce reimbursement for colonoscopy; ASGE, ACG, AGA oppose this
On July 8, CMS proposed to significantly reduce reimbursement for colonoscopy and other lower gastrointestinal endoscopy methods. In response, ASGE, ACG, and AGA issued a joint statement expressing their opposition.
Such a drastic reduction is a compromise to the national public health effort to reduce input on rectal colon cancer, the statement reads.
Screening colonoscopy prolongs survival of patients with rectal cancer compared to diagnostic colonoscopy
Recent study data show that patients with colorectal cancer detected by screening colonoscopy survive longer than patients with rectal cancer detected by diagnostic colonoscopy.
”Although CRC screening methods vary from country to country, our main conclusion that cancer diagnoses made by screening colonoscopy prolong survival may be applicable to other countries.” Kilian Friedrich, MD, of the Department of Gastroenterology at Heidelberg University Hospital, and his colleagues wrote.
3. Health care workers need longer operating hours to ensure the safety of using screening colonoscopy
Trained endoscopy nurses are able to use screening endoscopes safely and reasonably, it just takes them longer to make adenoma detection rates comparable to those of internal medicine endoscopists.
The investigators wrote: We believe that no more direct assistance is needed in the operation of the colonoscope by the health care provider; it is sufficient to ensure that the endoscopist is next door with adequate supervision.
4. Higher-quality screening colonoscopy reduces the incidence and mortality of rectal colon cancer without requiring high costs
Screening colonoscopy with higher adenoma detection rates was found to be associated with up to a 50-60% reduction in the risk of survival due to colorectal cancer incidence and mortality, without the higher costs associated with this technology.
Our results demonstrate that adenoma detection rates may be an important indicator of the quality of colonoscopy, says Reinier G.S. Meester of Erasmus MC University Medical Center.
5. Split bowel cleansing protocol superior to a full day of preparation before colonoscopy
A recent meta-analysis found that a split bowel cleansing protocol was superior in terms of bowel cleansing quality and patient preference compared with a full day of preparation prior to the procedure.
In the article, the researchers concluded, “Split bowel cleansing protocols have the highest bowel cleansing quality of all types of bowel preparations.”
6. first-degree relatives of young colorectal cancer patients rarely receive colonoscopy
Colonoscopy screening rates have increased fivefold over the past 10 years, but first-degree relatives of patients with colorectal cancer who are younger than 50 years old are less likely to receive colonoscopy screening than the general population who are older than or equal to 50 years old.
Dr. SudhaXirasagar and colleagues write, “Our study suggests that colorectal cancer screening rates should be increased in this subgroup of the population, particularly among first-degree relatives of colorectal cancer patients aged less than 50 years. This is because of the increased incidence of colorectal cancer in this age group in the United States.”
7. colonoscopic surveillance reduces colorectal cancer risk and the need for ulcerative colitis-related colectomy
A 40-year analysis of a colonoscopy surveillance program for ulcerative colitis-associated neoplasms found that colonoscopy surveillance plays an important role in reducing the risk of colorectal cancer and reducing the need for colectomy.
The investigators said, “In recent years, the use of pigmented endoscopy has increased the detection rate of heterogeneous growths. This has not led to a reduction in the overall risk of colorectal cancer, but it can identify high-risk patients at an early stage and has important implications for reducing the risk of advanced and interstage cancers.”
