Test characteristics of computed tomographic colonography (CTC) for detecting colorectal polyps...

OBJECTIVE CT-colonography has been suggested to be less burdensome for primary colorectal cancer (CRC) screening than colonoscopy. To compare the expected and perceived burden of both in a randomised trial. DESIGN 8844 Dutch citizens aged 50-74 years were randomly invited for CRC screening with colonoscopy (n=5924) or CT-colonography (n=2920). Colonoscopy was performed after full colon lavage...

BACKGROUND Low-socioeconomic status (SES) is associated with a higher colorectal cancer (CRC) incidence and mortality. Screening with colonoscopy, the most commonly used test in the US, has been shown to reduce the risk of death from CRC. This study examined if, among insured persons receiving care in integrated healthcare delivery systems, differences exist in colonoscopy use according to neig...

OBJECTIVE To quantify the proportion of requests for colonoscopy that are performed as flexible sigmoidoscopy and documented reasons for this in ordinary UK hospital practice. To determine the effect these requests have on colonoscopy completion rate if they are included in the denominator of the calculated rate by individual endoscopist. DESIGN Retrospective study of 22 months flexible sigmo...

Colonoscopy is a procedure often experienced as uncomfortable and worrying. Music has been reported to reduce discomfort during colonoscopy; however, no study in a Swedish setting has been found. The purpose of this randomized controlled trial was to analyze the effects of sedative music on patients' experience of anxiety, pain, relaxation, and well-being during colonoscopy. Prior to colonoscop...

BACKGROUND AND STUDY AIMS Abdominal discomfort and bloating are common symptoms after colonoscopy. We aimed to compare the effects of direct rectal suction with insertion of a rectal tube on reducing abdominal symptoms after unsedated colonoscopy. PATIENTS AND METHODS Consecutive patients undergoing colonoscopy were randomized to have direct rectal suction or placement of a rectal tube immedi...

Colonoscopy has already demonstrated to reduce colorectal cancer risk and mortality by detection resection of precursor lesions. However, its role for preventing still limitations. Image enhancement techniques have been developed improve the diagnostic yield colonoscopy optimize management surveillance We aimed review basic concepts, benefits, limitations, practical applications image in averag...

background: the appropriate colon cleansing is a major determinant of quality of colonoscopy. the aim of this study was to compare the efficacy and tolerability of the morning (am) peg (polyethylene glycol) solution to previous-evening (pm) peg solution for the afternoon colonoscopy. methods: this comparative study compared the am to pm prep for afternoon outpatient colonoscopy. the subjects ra...

introduction: ulcerative colitis (uc) is a chronic colonic mucosal disease with unknown etiology. its frequency is rising in our country in recent years. with application of newer topical preparation in treatment of uc a true recognition of its colonic extension pattern is needed.  reports from iran are scarce. reports from the world are contradictory. this study, therefore, was done to determi...

The costs of computed tomographic colonography (CTC) are not yet established for screening use. In our study, we estimated the threshold costs for which CTC screening would be a cost-effective alternative to colonoscopy for colorectal cancer (CRC) screening in the general population. We used the MISCAN-colon microsimulation model to estimate the costs and life-years gained of screening persons ...
