If you’re at the beginning of your career as an endoscopist, here’s a must read article about how to perform colonoscopy, published jointly in Gastrointestinal Endoscopy and Endoscopy with the occasion of Colorectal Cancer Awareness Month in March 2018: How I do colonoscopy, by Jerome D. Waye and Siwan Thomas-Gibson. The article features a graphic with recommended position changes during colonoscopy which may aid intubation of different colon segments.
Also here’s some good videos on this topic: Basic techniques of Colonoscope insertion, a 13 videos playlist by Olympus.
We wish you high cecal intubation rates!
