The PENTAX Medical Quality in Colonoscopy-App provides the unique combination of the scientific background of Quality in Colonoscopy metrics and how PENTAX Medical supports this metrics with the latest technologies in colonoscopy.Colonoscopy is a commonly performed procedure for the diagnosis and treatment of a wide range of conditions and symptoms and for the screening and surveillance of colorectal diseases. Many studies demonstrate that colonoscopy offers substantial protection against colorectal cancer (CRC). Nevertheless several other studies have raised warnings about the limited effectiveness of colonoscopy for the prevention of CRC, especially of the proximal colon (larger surface, bowel preparation more difficult, more flat lesions/adenomas and serrated lesions are detected in the right side of the colon). The pillars of Quality in Colonoscopy (adenoma detection rates, caecal intubation rates, withdrawal time, patient comfort and lowest rate of complications) are quality metrics for objective evaluation and feedback. They contribute to the continuous monitoring of the Quality in Colonoscopy, and ultimately might reduce the number of interval CRCs. The targets of every medical intervention are safety and effectiveness of the procedure. The wide range of technologies and HD+ colonoscopes from PENTAX Medical sustain each of the five pillars of Quality in Colonoscopy as supported by the clinical content of this app.The target group for this app is physicians and practitioners.
