BACKGROUND Although colonoscopy is rarely of clinical use in irritable bowel syndrome (IBS), it is, nonetheless, frequently performed in IBS. Proponents contend that a normal colonoscopy provides reassurance and improves health-related quality of life (HRQOL). However, no previous data have measured these effects. We sought to measure the association of a normal colonoscopy with reassurance and...

PURPOSE Because colonoscopy after colorectal cancer surgery is important for detecting synchronous or metachronous colorectal neoplasms, we designed this study to investigate, by using postoperative colonoscopy, the miss rate for and the location of polyps remaining after colorectal cancer surgery. METHODS In a prospectively-collected patient database, 264 patients were shown to have undergon...

BACKGROUND In average-risk individuals aged 50 to 75 years, there is no difference in life-years gained when comparing colonoscopy every 10 years vs. annual fecal immunochemical testing (FIT) for colorectal cancer screening. Little is known about the preferences of patients when they have experienced both tests. METHODS The study was conducted with 954 patients from the University of Iowa Hos...

background: colonoscopy is used for both diagnostic as well as therapeutic purposes in patients with lower gi symptoms. the aim of this study was to assess the clinical manifestations and to determine the colonoscopic findings of children with lower gi symptoms attending a pediatric hospital in tehran. materials and methods: during a 5-year period (1996-2001), all children less than 16 years of...

OBJECTIVE Our study was a randomized, controlled trial to assess a novel strategy that provides comprehensive colorectal cancer screening in a single visit versus traditional sigmoidoscopy and, where appropriate, colonoscopy on a subsequent day. METHODS Consecutive patients referred for screening were randomized to control or so-called "conversion" groups. Patients in the control group were p...

BACKGROUND AND STUDY AIMS  Incomplete colonoscopy may occur as a result of colon angulation (adhesions or diverticulosis), endoscope looping, or both. Specialty endoscopes/devices have been shown to successfully complete prior incomplete colonoscopies, but may not be widely available. Radiographic or other image-based evaluations have been shown to be effective but may miss small or flat lesion...

During colonoscopy, air insufflation to distend the lumen and facilitate careful inspection and scope insertion can induce pain and cause discomfort. Carbon dioxide (CO2) insufflation can decrease abdominal pain and discomfort during and after colonoscopy. The advantage of CO2 insufflation is the rapid absorption of the gas across the intestine. Another painless option is water-assisted colonos...

OBJECTIVE A systematic review of the literature was conducted to characterise patients' own experience of colonoscopy in the screening context. METHODS A search strategy was applied in MEDLINE, EMBASE and PSYCHinfo (1996-2009). Thematic analysis and narrative summary techniques were used. RESULTS Fifty-six studies met eligibility criteria and were included in the analysis. Seven studies exa...

Background Adherence to colonoscopy recommendations can reduce colorectal cancer (CRC) morbidity and mortality. However, little is known about the use of colonoscopy among persons at risk for Lynch syndrome prior to clinical genetic testing (CGT) and how notification of mutation carrier status affects screening behaviors. The goal of this study was to evaluate colonoscopy use and attitudes towa...

OBJECTIVE Currently, the best method for CRC screening is colonoscopy, which ideally (where possible) is performed under partial or deep sedation. This study aims to evaluate the efficacy of the Endotics System, a new robotic device composed of a workstation and a disposable probe, in performing accurate and well-tolerated colonoscopies. This new system could also be considered a precursor of o...
