Effect of real-time magnetic endoscope imaging on the teaching and acquisition of colonoscopy skills: results from a single trainee.

Background And Study Aims: Most trainees have little concept of the loops that occur during colonoscopy, and have difficulty in appreciating the combination of withdrawal and torquing manoeuvres that are essential to achieving complete colonoscopy. Real-time magnetic endoscope imaging (MEI) allows visualization of shaft looping, and so makes intuitive the manoeuvres necessary to straighten the colonoscope shaft.

Patients And Methods: Consecutive routine colonoscopies were performed by a single trainee (with previous experience of 15 colonoscopies).

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.

Patient pain during colonoscopy: an analysis using real-time magnetic endoscope imaging.

Background And Study Aims: Colonoscopy is generally perceived as being a painful procedure. Contributory factors are: stretching of the colonic wall and mesenteric attachments from looping of the instrument shaft, overinsufflation, the degree of torque or force applied to the colonoscope shaft, and patient pain threshold. The aim of this study was to determine the frequency of pain episodes experienced during diagnostic colonoscopy and the corresponding colonoscope configuration, utilizing real-time magnetic endoscope imaging (MEI).
