How Can Olympus Technology Help?
For a long time, ScopeGuide has been considered as a training tool for inexperienced endoscopists. In a RCT, trainees achieved a much higher cecal intubation rate and required less help from seniors compared with trainees who did colonoscopies with on-demand fluoroscopy.
Not only trainees benefit from ScopeGuide: ScopeGuide increases the cecal intubation rate for both inexperienced and experienced gastroenterologists
(30,31) and improves cecal intubation times and patient pain scores.
The latest EVIS EXERA III colonoscopes may even increase this effect: CF-HQ190 and PCF-H190D with in-built ScopeGuide functionality are additionally equipped with Responsive Insertion Technology, reducing the cecal insertion time by approximately 20%. (32)
Cecal intubation rate is a quality indicator for colonoscopy. The literature suggests that a gastroenterologist should reach the cecum in at least 90% of the exams to ensure high quality clinical service.
Expertise in colonoscopy (e.g. cecal intubation rate > 90%) is usually reached after 200-250 examinations.
(27) But aside from expertise, risk factors such as patient age, gender, BMI, previous surgery, or preparation quality may influence the success rate of cecal intubation.
Colonic insertion may cause patient pain with the sigmoid colon being the predominant location causing pain during colonoscopy. (28)
