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 ...

background : colorectal cancer is the most common cancer and the second leading cause of cancer deaths. annually it is the cause of more than 500000 deaths worldwide. therefore, detection and treatment of these tumors could potentially enhance recovery and improve prognosis. this study determines the frequency of colorectal tumors among patients who underwent colonoscopies in imam khomeini hosp...

postpolypectomy bleeding and perforation are the major complications of colonoscopy. this report presents a rare case of colon obstruction immediately after colonoscopy. a 56-year-old man underwent colonoscopy because of 6 months lower abdominal pain. colonoscopy revealed diverticulosis and multiple small sessile polyps in sigmoid colon. biopsy samples were taken from the polyps and the procedu...

case presentation we report a case of idiopathic colonic varices, diagnosed at a routine colonoscopy performed for nespecific abdominal disturbances in a female patient without liver disease or pancreatic conditions responsible for portal hypertension development. conclusions the development of colonic varices in the absence of a certain trigger represents a major issue for practitioners due to...
