Predictors of success of conventional ERCP for bile duct stones and need for single-operator cholangioscopy.

The characteristics of difficult stones requiring cholangioscopy-assisted lithotripsy are poorly defined. We sought to determine clinician perception of these characteristics and decision-making in biliary endoscopy. One hundred twenty-four delegates attending an online course were invited to assess 20 clinical stone cases.

UK and Ireland Joint Advisory Group (JAG) consensus statements for training and certification in diagnostic endoscopic ultrasound (EUS).

Background And Aims: International endoscopy societies vary in their approach for credentialing individuals in endoscopic ultrasound (EUS) to enable independent practice; however, there is no consensus in this or its implementation. In 2019, the Joint Advisory Group on GI Endoscopy (JAG) commissioned a working group to examine the evidence relating to this process for EUS. The aim of this was to develop evidence-based recommendations for EUS training and certification in the UK.

Immune checkpoint inhibitor-related cholangiopathy: Novel clinicopathological description of a multi-centre cohort.

Background And Aims: Cholestatic liver dysfunction is common in immune-related hepatitis (irH) during treatment with immune checkpoint inhibitors (CPI) for malignancy. We investigated the spectrum of bile duct injury and associated natural history in this cohort.

Method: Clinical, laboratory, radiological and histopathological data in patients with evidence of bile duct injury during CPI treatment from 2018 to 2020 was collected in three tertiary hospitals.

Endoscopic biliary therapy in the era of bariatric surgery.

There is an increasing demand and availability of bariatric surgery, with a range of procedures performed, some leading to altered upper gastrointestinal anatomy. The patient population undergoing bariatric surgery is also at increased risk of gallstones and biliary stone disease. Endoscopy (ie, endoscopic retrograde cholangiopancreatography) is the cornerstone of management of biliary stone disease, but may be challenging after bariatric surgery.

Near-focus narrow-band imaging classification of villous atrophy in suspected celiac disease: development and international validation.

Background And Aims: There are no agreed-on endoscopic signs for the diagnosis of villous atrophy (VA) in celiac disease (CD), necessitating biopsy sampling for diagnosis. Here we evaluated the role of near-focus narrow-band imaging (NF-NBI) for the assessment of villous architecture in suspected CD with the development and further validation of a novel NF-NBI classification.

Methods: Patients with a clinical indication for duodenal biopsy sampling were prospectively recruited.

Live endoscopy events (LEEs): European Society of Gastrointestinal Endoscopy Position Statement - Update 2021.

The European Society of Gastrointestinal Endoscopy (ESGE) is dedicated to improving the quality of gastrointestinal endoscopy, including through educational activities such as live endoscopy events (LEEs). The primary goal of LEEs should be to facilitate the improvement of endoscopic patient care through the acquisition of best endoscopic practice. Patients should not expect additional benefit from being treated during a LEE compared to a routine setting.
