TUESDAY, May 22 (HealthDay News) -- Patients undergoing screeningfor colorectal cancer tend to prefer colonoscopy versus computedtomography colonography (CTC); and for those undergoingcolonoscopy, the tolerability of bowel preparation is associatedwith improved polyp and adenoma detection, according to two studiespresented at the annual Digestive Disease Week, held from May 19 to22 in San Diego. George Ou, M.D., from the University of British Columbia inVancouver, Canada, and colleagues investigated patient satisfactionfollowing tandem CTC and colonoscopy among a cohort of 90individuals with a mean age of 55 years. The researchers found thata significantly larger proportion of patients felt less anxious andexperienced less pain and discomfort during colonoscopy. Overall,colonoscopy was considered more satisfactory by 30 percent ofpatients, compared with the 4 percent who considered CTC moresatisfactory. |
Seventy-seven percent of patients preferredcolonoscopy as a repeat screening test. Edward W. Holt, M.D., from the California Pacific Medical Center inSan Francisco, and colleagues conducted a prospective study of 430patients (mean age, 60.4 years) presenting for colonoscopy toinvestigate the correlation between patient perception of bowelpreparation and the quality of preparation and yield ofcolonoscopy. The researchers found that there were significantcorrelations between the quality of bowel preparation and theself-reported percent of preparation completed, clarity of bowelmovements, and tolerability of bowel preparation. Tolerability ofbowel preparation correlated significantly with the detection ofpolyps and adenomas.
"Patients who self-reported a better experience with bowelpreparation had significantly greater rates of both adenoma andpolyp detection. Efforts to make bowel preparation more tolerablefor patients may lead to improvements in the quality of bowelpreparation and in adenoma yield," Holt and colleagues conclude. Several authors of the Ou study disclosed financial ties to thepharmaceutical industry. One author of the Holt study disclosedfinancial ties to the San Francisco Endoscopy Center.
