Endoscopists consistently underestimated polyp size. Fixation had no effect on polyp size. Pathologists' measurement of polyp size on fixed specimens should determine the need for further colonoscopic follow-up.
This pilot study has confirmed that aerobic EDD is feasible and well accepted by patients on hospital haemodialysis. EDD reduced anxiety scores and showed a trend for an improved level of aerobic fitness.
Colonoscopic lesion localisation was found to be inaccurate in 79.3% cases, and with pre-operative CT unable to detect all lesions, this study confirms that accurate lesion localisation in the modern era is increasingly reliant on colonoscopy. Incomplete colonoscopy was the only significant factor that influenced inaccurate lesion localisation at colonoscopy.
Half the FOB screen-positive patients had bowel symptoms. Symptoms in these patients had no correlation with an increased rate of neoplasia. The PPV for neoplasia is superior in symptomatic and asymptomatic screen-positive patients when compared to conventional urgent symptom-based referral.
Colonoscopic lesion localisation is inaccurate in 19.0% of cases and occurred throughout the colon with a change in on-table surgical management in 6.3%. With CT unable to visualise lesions in just under a quarter of cases, particularly in the screening population, preoperative localisation is heavily reliant on colonoscopy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
