Use of video and magnetic endoscope imaging for rating competence at colonoscopy: validation of a measurement tool.

Background: Counting the number of procedures performed provides at best a crude measure of technical competence in colonoscopy. The aim of this study was to develop and validate a qualitative and a quantitative score for measuring technical competency in colonoscopy using videotape evaluation.

Methods: Eighteen endoscopists with varying levels of experience were prospectively videotaped during colonoscope insertion.

Total colonic dye-spray increases the detection of diminutive adenomas during routine colonoscopy: a randomized controlled trial.

Background: Small adenomas may be missed during colonoscopy, but chromoscopy has been reported to enhance detection. The aim of this randomized-controlled trial was to determine the effect of total colonic dye spray on adenoma detection during routine colonoscopy.

Methods: Consecutive outpatients undergoing routine colonoscopy were randomized to a dye-spray group (0.

The variable stiffness colonoscope: assessment of efficacy by magnetic endoscope imaging.

Background: Variable-stiffness colonoscopes combine the flexibility of pediatric instruments for negotiation of the sigmoid colon with the ability to stiffen the insertion tube to prevent or control looping after straightening. Previous studies have found wide variation in the efficacy of the stiffening mechanism. Thus, two studies were conducted to assess the potential benefit of the stiffening device and its optimal use.

Effect of magnetic endoscope imaging on patient tolerance and sedation requirements during colonoscopy: a randomized controlled trial.

Background: Pain during colonoscopy is primarily related to mesenteric stretching from looping of the colonoscope insertion tube. Prompt recognition and removal of loops reduces patient discomfort and may lessen sedation requirements. Magnetic endoscope imaging allows real-time visualization of the colonoscope during insertion.

Colonoscopy at a combined district general hospital and specialist endoscopy unit: lessons from 505 consecutive examinations.

Provisional reports from the Intercollegiate British Society of Gastroenterology National Colonoscopy audit show completion rates of 57-77% for the procedure and poor levels of training and supervision. We prospectively audited all aspects of colonoscopy performed at a combined district general hospital and specialist endoscopy unit. Details of referral, examination, endoscopist, complications and follow-up were recorded and patients were sent questionnaires for long-term follow-up.

Treatment with argon plasma coagulation reduces recurrence after piecemeal resection of large sessile colonic polyps: a randomized trial and recommendations.

Background: Recurrence is frequent after piecemeal snare resection of large sessile colorectal polyps. The aim of this study was to evaluate the safety and efficacy of argon plasma coagulation (APC) in preventing recurrence when applied to the edge and base of the polypectomy site after apparently complete piecemeal resection.

Methods: Patients with large (>1.
