Water exchange versus carbon dioxide insufflation in unsedated colonoscopy: a multicenter randomized controlled trial (FREE ACCESS)

Kjetil Garborg, Michal F. Kaminski, Wolfgang Lindenburger, Håvard Wiig, Audun Hasund, Ewa Wronska, Rolf Bruun Bie, Britta Kleist, Leif Løvdal, Øyvind Holme, Mette Kalager, Geir Hoff, Michael Bretthauer

This randomized trial compared water exchange with carbon dioxide insufflation for unsedated colonoscopy in 473 patients. No significant differences were found with respect to on-demand sedation (6% in each group) and to overall pain scores during and following colonoscopy. More patients reported no procedural pain with water exchange (44%) than with carbon dioxide insufflation (31%). The cecal intubation time was fairly long in both groups (>10 minutes), and rates of adenoma detection were comparable. Read more.

Endoscopists can sustain high performance for the optical diagnosis of colorectal polyps following standardized and continued training  (FREE ACCESS)

This study, involving a cohort of 558 patients with 445 polyps, examined whether the quality of real-time optical polyp diagnosis with narrow band imaging could be maintained over a 14-month period. Endoscopists completed an initial standardized training module, which they repeated halfway through the time period. Quality benchmarks for optical polyp diagnosis were reached and accuracy values remained similar over the entire study period. Read more.

High quality of screening colonoscopy in Austria is not dependent on endoscopist specialty or setting (FREE ACCESS)

Previous data have suggested that colonoscopy performance may differ according to operator. After assessing more than 59 000 colonoscopies, the authors found no quality differences among the participating endoscopists who were working within a regulated quality program. Read more.
