BACKGROUND Inadequate bowel preparation during screening colonoscopy necessitates repeating colonoscopy. Studies suggest inadequate bowel preparation rates of 20-60%. This increases the cost of colonoscopy for our society. AIM The aim of this study is to determine the impact of inadequate bowel preparation rate on the cost effectiveness of colonoscopy compared to other screening strategies fo...

OBJECTIVES Obesity is an important risk factor for the development of colorectal cancer (CRC). Although the impact of bariatric surgery on CRC is conflicting, its impact on precursor lesions is unknown. The aim of this study was to determine whether bariatric surgery before index screening colonoscopy is associated with decreased development of colorectal adenomas. METHODS We performed a retr...

Colonoscopy is the most widely used screening modality for the detection and removal of colon polyps and for the prevention of colorectal cancer. To identify all colon lesions and reduce the risk of colorectal cancer, it is important to perform a complete colonoscopy. The success of screening colonoscopy depends upon several parameters, including bowel preparation and adenoma detection rate. In...

BACKGROUND & AIMS The sensitivity of computed tomographic (CT) virtual colonoscopy (CT colonography) for detecting polyps varies widely in recently reported large clinical trials. Our objective was to determine whether a computer program is as sensitive as optical colonoscopy for the detection of adenomatous colonic polyps on CT virtual colonoscopy. METHODS The data set was a cohort of 1186 s...

Abstract Cytomegalovirus (CMV) is a virus that can be consider as invasive infection after transplantation or chemotherapy, long-term corticosteroid users or in immunodeficient patients such as HIV. Different complications were seen in immunocompetent patients but colitis rarely occurs. The diagnosis of CMV was based on pathology by colonoscopy, positive CMV antigen and high CMV-IgM titer serum...

Colonoscopy is currently regarded as the gold standard and preferred method of screening for colorectal cancer (CRC). However, the benefit of colonoscopy screening may be blunted by low participation rates in population-based screening programs. Harmful effects of population-based colonoscopy screening may include complications induced by colonoscopy itself and by sedation, psychosocial distres...

PURPOSE The incidence of complications after colonoscopy is very low. The complications after colonoscopy that are of clinical concern are bleeding and perforation. The present study was conducted to determine the clinical outcomes and the risk factors of a colostomy or a colectomy after colonoscopic colon perforation. METHODS From March 2009 to December 2012, the records of all patients who ...
