Background And Study Aims: Piecemeal EMR of large (≥20mm) non-pedunculated colorectal polyps (LNPCPs) is succeeded by a 6-month surveillance endoscopy to evaluate the post-EMR scar for recurrence. Data from expert centers suggest that routine tattoo placement and scar biopsies can be omitted, but data from community hospitals are lacking.
Patients And Methods: In a post-hoc analysis of the STAR-LNPCP study (NTR7477), containing prospective data on 6-month post-pEMR scar assessments in 30 Dutch community hospitals (October 2019 to May 2022), the agreement between optical assessment and histological confirmation by routine biopsies was evaluated.
Background & Aims: Although primary biliary cholangitis (PBC) is considered a rare disorder, accurate determination of its incidence and prevalence remains challenging due to limited comprehensive population-based registries. We aimed to assess the incidence and prevalence of PBC in the Netherlands over time through the nationwide Dutch PBC Cohort Study (DPCS).
Methods: DPCS retrospectively included every identifiable patient with PBC in the Netherlands from 1990 onwards in all 71 Dutch hospitals.
Background: Recognition of submucosal invasive colorectal cancer (T1 CRC) is difficult, with sensitivities of 35 %-60 % in Western countries. We evaluated the real-life effects of training in the OPTICAL model, a recently developed structured and validated prediction model, in Dutch community hospitals.
Methods: In this prospective multicenter study (OPTICAL II), 383 endoscopists from 40 hospitals were invited to follow an e-learning program on the OPTICAL model, to increase sensitivity in detecting T1 CRC in nonpedunculated polyps.
A Prediction Model for Successful Increase of Adalimumab Dose Intervals in Patients with Crohn's Disease: Secondary Analysis of the Pragmatic Open-Label Randomised Controlled Non-inferiority LADI Trial.

Article Synopsis
- In the LADI trial, researchers found that extending adalimumab (ADA) dosing intervals was just as effective as standard dosing for Crohn's disease patients in remission.
- The study aimed to create a prediction model to identify patients who could successfully increase their dosing intervals based on trial data.
- Results showed that 60.6% of patients successfully extended their dosing, with certain factors (like smoking and prior surgeries) making success less likely; the model's effectiveness needs further external validation before clinical use.
Objective: Endoscopic mucosal resection (EMR) is the preferred treatment for non-invasive large (≥20 mm) non-pedunculated colorectal polyps (LNPCPs) but is associated with an early recurrence rate of up to 30%. We evaluated whether standardised EMR training could reduce recurrence rates in Dutch community hospitals.
Design: In this multicentre cluster randomised trial, 59 endoscopists from 30 hospitals were randomly assigned to the intervention group (e-learning and 2-day training including hands-on session) or control group.
