Fast-tracking ERCP learning with the Boškoski-Costamagna Trainer: results of a multicenter randomized clinical trial
Achieving competence in endoscopic retrograde cholangiopancreatography (ERCP) requires extensive training. Recognizing the potential of simulator-based education for safe and effective skill development, we aimed to assess whether initial training with the Boškoski-Costamagna ERCP Trainer (BCT) is beneficial compared with conventional training alone (i.e. predictive validity).
Virtual scale endoscope vs snares for size measurement accuracy of smaller colorectal polyps: A randomized controlled trial
Accurate measurement of polyp size during colonoscopy is crucial for informing clinical decisions such as resection techniques and surveillance scheduling. This study aimed to compare polyp size measurement accuracy when using a virtual scale endoscope (VSE) or snare-based polyp size measurement.

Procedural outcomes of a novel underwater injection endoscopic mucosal resection technique for colorectal polyps ≥10 mm (with video)
Background and Aims It is uncertain whether underwater EMR (U-EMR) enables resection of the submucosal tissue with sufficient margins for T1 colorectal cancer (T1-CRC) because U-EMR forgoes submucosal injection. Therefore, we developed a novel 'underwater injection EMR (UI-EMR)' method that combines submucosal injection with U-EMR to obtain adequate vertical margin (VM). Patients and methods We retrospectively analyzed procedure-related outcomes of 135 consecutive lesions from patients who underwent UI-EMR for ≥10 mm, non-pedunculated colorectal polyps (median lesion size; 15 mm). The outcomes included en bloc, R0, RX, R1 resection rates and adverse events. Additionally, the VM distance of seven T1-CRCs was evaluated. Results En bloc resection was achieved in 127 lesions (94.1%). R0 and RX resection were observed in 92 (68.2%) and 42 lesions (31.1%), respectively, while R1 resection was seen in only one lesion (0.7%). We identified two lesions (1.5%) with adverse events, which were delayed bleeding. In T1-CRCs, all seven cases had free VMs, and the median VM distance was 1140 µm (range, 731-1570 µm). Conclusions UI-EMR safely demonstrated high success rates for en bloc resection, and potentially ensures sufficient VM. This technique might become an option, particularly for relatively small lesions concerning for T1-CRC and deserve further study.
