Article Synopsis
- Digital single-operator cholangioscopy (DSOC) is a technique for diagnosing and treating biliary duct disorders, but traditional systems faced issues like cost and image quality.
- A new system called eyeMAX was developed to improve these limitations; the study assessed its diagnostic accuracy and safety across 80 patients from two cohorts—diagnostic and therapeutic.
- Results showed high sensitivity (91.6%) and specificity (87.5%) for diagnosing neoplasms, with successful stone removal for 71% of patients who required treatment, and no adverse events reported during the procedures.
Background And Aims: EUS-guided radiofrequency ablation (EUS-RFA) has emerged as an alternative for the local treatment of unresectable pancreatic ductal adenocarcinoma (PDAC). We assessed the feasibility and safety of EUS-RFA in patients with unresectable PDAC.
Methods: This study followed an historic cohort compounded by locally advanced (LA-) and metastatic (m)PDAC-naïve patients who underwent EUS-RFA between October 2019 and March 2022.
Background: We aimed to develop a convolutional neural network (CNN) model for detecting neoplastic lesions during real-time digital single-operator cholangioscopy (DSOC) and to clinically validate the model through comparisons with DSOC expert and nonexpert endoscopists.
Methods: In this two-stage study, we first developed and validated CNN1. Then, we performed a multicenter diagnostic trial to compare four DSOC experts and nonexperts against an improved model (CNN2).
Introduction: deep cannulation of the common bile duct is essential in endoscopic retrograde cholangiopancreatography (ERCP). However, cannulation is not possible in approximately 20 % of the cases with the usual techniques. Pre-cutting is an alternative that allows cannulation in difficult cases although its success is not guaranteed.
