Sigmoidoscopy News and Research

RSS

Sigmoidoscopy is the examination of the lower colon using a sigmoidoscope, inserted into the rectum. A sigmoidoscope is a thin, tube-like instrument with a light and a lens for viewing. It may also have a tool to remove tissue to be checked under a microscope for signs of disease. Also called proctosigmoidoscopy.

Colorectal cancer screening disparities in certain regions

Individuals from certain areas of the United States are more likely to get screened for colorectal cancer than those from other areas, particularly when comparing non-whites living in different parts of the country. That is the conclusion of a new study published early online in Cancer, a peer-reviewed journal of the American Cancer Society. Additional research is needed to better understand how colorectal cancer screening disparities develop in some regions and not in others.

Cancers detected late leading to unnecessary deaths: Report

A new report released Wednesday by the U.S. Centers for Disease Control and Prevention (CDC) says that in spite of the widely available screening tests many cancers are not diagnosed until the disease is well-advanced and, therefore, less treatable and more fatal. The report says that half of colorectal cancers and cervical cancers and one-third of breast cancers in the United States are detected at a late stage.

Screening colonoscopy rates for women do not increase when offered to be done by female endoscopists: Study

A new study from researchers in Colorado shows that women offered a female endoscopist were not more likely to undergo a screening colonoscopy than those who were not offered this choice. Past surveys have shown preferences for female endoscopists seem to be common among women. In this study, a patient outreach program failed to support the notion that rates of screening colonoscopy can be increased by offering women the option of a screening colonoscopy performed by a female endoscopist.

Study highlights need to address overuse, underuse of colorectal cancer screening tests

Only one-fifth of primary care physicians in the US follow practice guidelines for colorectal cancer screening for all the tests they recommend, according to Dr. Robin Yabroff from the National Cancer Institute and her colleagues. About 40 percent followed guidelines for some of the tests they recommended and the remaining 40 percent did not follow guidelines for any of the screening tests they recommended.

Combined technologies offer promise for detecting colon cancer in women

A team led by a Northwestern University biomedical engineer has found that combining novel optical technologies with a common colon cancer screening test may allow doctors to more accurately detect the presence of colon cancer, particularly in women.

Current screening methods for FOBT are often not appropriate

More than 75 percent of primary care physicians in the United States who order or perform the fecal occult blood test as a screening option for colorectal cancer perform an in-office test rather than relying on the home-based test, even though the home-based test is more accurate, a study by the Centers for Disease Control and Prevention has found.

Colonoscopies performed by non-gastroenterologists may increase risk of developing subsequent CRC

Following a negative complete colonoscopy, those who had their colonoscopies at a hospital and had their procedures performed by a non-gastroenterologist may be at a significantly increased risk of developing subsequent colorectal cancer (CRC), according to a new study in Clinical Gastroenterology and Hepatology, the official journal of the American Gastroenterological Association (AGA) Institute.

CT colonography remains an effective colorectal cancer screening tool for older individual

Computed tomographic colonography (CTC), also known as virtual colonoscopy, remains effective in screening older patients for colorectal cancer (CRC), produces low referral for colonoscopy rates similar to other screening exams now covered by Medicare, and does not result in unreasonable levels of additional testing resulting from extracolonic findings, according to a study published in the February issue of Radiology.

New blood test to identify changes in DNA linked with colorectal cancer now available in the U.S.

A new blood test that identifies changes in DNA associated with colorectal cancer is now available in the U.S. through Quest Diagnostics Incorporated, the world's leading cancer diagnostics company. The test is designed to aid the detection of colorectal cancer, the third leading cause of cancer-related deaths.

National survey reveals many Canadians understand risk of colon cancer, but are not taking action

A new national survey reveals that while almost all Canadians understand the importance of getting checked for colon cancer, most have not had a screening test and are confused about how and when it should happen.

Studies highlight race- and gender-specific disparities in gastrointestinal disease

Three studies presented this week at the American College of Gastroenterology's 74th Annual Scientific meeting in San Diego underscore the growing disparities in gastrointestinal disease, particularly colon cancer and Barrett's Esophagus, among certain ethnic and gender populations, including African Americans, Latinos and women. These race- and gender-specific disparities underscore the need for education and vigilance among these populations and perhaps more aggressive screening tactics than the population in general.

Colonoscopy recommended as primary screening method for colorectal cancer, researchers report

Researchers from Taiwan report in a new study that unsedated colonoscopy for primary colorectal cancer screening is well accepted in a majority of patients. Sedation is typically used for colonoscopy to make the patient feel comfortable during the procedure.
