Colonoscopies Done In The Early Morning Hours Yield More Accurate Results –Study Reveals

The efficacy of a colonoscopy screening could depend on what time during the day one is undergoing it. A novel UCLA study has pointed out that colonoscopies performed in the after-dawn hours detected more polyps in each patient as compared to those that were screened during the later part of the day.

The findings that were printed in the November edition of the journal Clinical Gastroenterology and Hepatology indicated that further research on this part would be needed to probably improve the results of the colonoscopy screenings. The researchers stated that though the present study was conducted in one institution, the medical setup was alike that of any other practice environment.

Dr. Brennan M.R. Spiegel, study author and director of the UCLA/Veterans Affairs Center for Outcomes Research and Education stated that their research was carried out in an academic-affiliated facility that surpassed printed quality yardstick for colonoscopy results.

Spiegel revealed that though this is a novel scenario of research, other studies have also shown analogous results, inclusive of the latest research from the Cleveland Clinic printed in the July edition of the American Journal of Gastroenterology.

A colonoscopy is the sole test that permits the detection and eradication of the polyps from the entire colon. Studies have revealed that polyp elimination has been linked to sixty to ninety percent decrease in colorectal cancer – that is deemed the second prevalent reason behind fatalities in the United States.

Spiegel further added that successful colonoscopy screenings are dependent on varied aspects like patient, procedure provider and procedural features – with even the timing when conducted playing crucial part.

The study conducted kept track of 477 patients that underwent colonoscopies over the time span of one year in the same location – the VA hospital. Researchers detected that those cases that underwent the procedure during the early morning time, commencing at 8:30 a.m. or before, spotted 27% more number of polyps – with 0.19 more polyps detected on the whole and 0.17 more polyps that were in their premalignant stages — for each patient than those cases screened later during the day. The amount of polyps diagnosed lowered as the hours advanced. This would mean that lesser than a quarter of a polyp in each patient –hence the risk for individual patients is quite less.

However, Spiegel added that in spite of the individual patient risk being quite less, when it is multiplied by thousands of patients all through the U.S., it would translate to many polyps being missed out – some of them might imminently turn cancerous. He pointed out that colonoscopy still continues to be increasingly effectual way of colon cancer screening irrespective of what time of the day it is done and cautioned against patients rushing or being adamant about being the foremost case of the day.

He stated that impact of scheduled time for screening for any patient is quite diminutive. He added that patients must sense total confidence in the efficacy of the colonoscopy procedure, irrespective of the timing of the day and must lay more stress on the quality and the proficiency of the doctor instead of the time they are undergoing the procedure.

The study authors also observed that these findings were self-determining, subsequent to taking into account many demographical and medical aspects, inclusive of the age, sex and past occurrence of polyps or cancer, along with the proficiency of the physician.

Researchers have pointed out that colonoscopies conducted in the early mornings could yield improved outcomes partially because of better bowel preparation the past night – however this does not totally elucidate the general study outcomes.

Spiegel added that exhaustion could don a part, as it would do in other vocations with drawn out and recurrent activities such as trucking, surgical intervention and aviation.

Spiegel stated that by maintaining a limit on the length of endoscopic work shift hours or other kinds of modifications could prove beneficial.
