Article Synopsis
- The study aims to investigate how modern treatments for inflammatory bowel disease (IBD) might alter its natural course through a new population-based cohort called IBSEN III.
- This ongoing study includes both adults and children from South-Eastern Norway (2.95 million residents) diagnosed with suspected IBD between 2017 and 2019, with comprehensive data collection at diagnosis and follow-ups.
- The cohort consists of 2168 patients, primarily with Crohn's disease and ulcerative colitis, and includes a unique biobank of biological samples, which will contribute valuable insights into IBD research in the future.
Gradual stiffness versus magnetic imaging-guided variable stiffness colonoscopes: A randomized noninferiority trial.
United European Gastroenterol J
February 2017
Background: Colonoscopes with gradual stiffness have recently been developed to enhance cecal intubation.
Objective: We aimed to determine if the performance of gradual stiffness colonoscopes is noninferior to that of magnetic endoscopic imaging (MEI)-guided variable stiffness colonoscopes.
Methods: Consecutive patients were randomized to screening colonoscopy with Fujifilm gradual stiffness or Olympus MEI-guided variable stiffness colonoscopes.
Background And Study Aims: Colonoscopy is frequently performed with opioid analgesia, but the impact of drug delivery timing has not been studied in detail. Low-dose opioids administered before the procedure may provide better pain control than on-demand administration when the patient experiences pain.
Patients And Methods: A total of 119 outpatients were randomized to receive 50 μg of fentanyl either before colonoscopy (routine group) or on demand if needed during the colonoscopy (on-demand group).
Background And Study Aims: Compared with air insufflation, water exchange and carbon dioxide (CO2) insufflation have been shown to reduce colonoscopy discomfort; however, head-to-head studies of the two methods are lacking. We aimed to compare water exchange and CO2 insufflation directly with regard to pain during primary unsedated colonoscopy.
Methods: Patients willing to undergo unsedated colonoscopy at three centers in Norway and Poland were randomized 1:1 to water exchange or CO2 insufflation during colonoscope insertion.
Background: Knowing the position of the endoscope within the abdomen is important for performing a high-quality, painless colonoscopy. The recently introduced magnetic endoscopic imaging (MEI) system provides a continuous, real-time image of the endoscope during the entire procedure.
Objective: To compare MEI versus standard colonoscopy with on-demand fluoroscopy on unsedated patients, as performed by experienced and inexperienced endoscopists.
