Exploring vision transformers for classifying early Barrett's dysplasia in endoscopic images: A pilot study on white-light and narrow-band imaging.

Background And Aim: Various deep learning models, based on convolutional neural network (CNN), have been shown to improve the detection of early esophageal neoplasia in Barrett's esophagus. Vision transformer (ViT), derived from natural language processing, has emerged as the new state-of-the-art for image recognition, outperforming predecessors such as CNN. This pilot study explores the use of ViT to classify the presence or absence of early esophageal neoplasia in endoscopic images of Barrett's esophagus.

Risk of bleeding after abdominal paracentesis in patients with chronic liver disease and coagulopathy: A systematic review and meta-analysis.

Abdominal paracentesis is a common procedure performed for both diagnostic and therapeutic purposes in patients with chronic liver disease and ascites. This review aims to provide an overview of the current evidence on the risk of bleeding associated with abdominal paracentesis. Electronic search was performed using PubMed, MEDLINE, and Ovid EMBASE from inception to 29 October 2023.

Spontaneous self-expulsion of an oesophageal duplication cyst.

A case report of an oesophageal duplication cyst in an adult patient with chronic cough and presenting with a "coughed out lump". This is an unusual presentation highlighting the importance of considering congenital duplication cysts in patients with chronic cough and no obvious respiratory cause.

High rates of treatment stage migration for early hepatocellular carcinoma and association with adverse outcomes: An Australian multicenter study.

Background And Aim: The rate of contraindications to percutaneous ablation (PA) for inoperable early hepatocellular carcinoma (HCC) and subsequent outcomes is not well described. We investigated the prevalence and outcomes of inoperable early HCC patients with contraindications to PA, resulting in treatment stage migration (TSM).

Methods: Barcelona Clinic Liver Cancer (BCLC) 0/A patients diagnosed between September 2013 and September 2019 across five hospitals were identified.

Dynamic functional clot formation in patients undergoing endoscopic mucosal resection.

Background And Aim: Electric burns can induce fibrinolytic activity. Endoscopic mucosal resection (EMR) is a minimally invasive technique utilizing electrocautery for resection of dysplastic lesions from the gastrointestinal tract. EMR's main complication is clinically significant postendoscopic bleeding.

Thermal Ablation of Mucosal Defect Margins Reduces Adenoma Recurrence After Colonic Endoscopic Mucosal Resection.

Background & Aims: Colorectal cancer (CRC) can be prevented by colonoscopy and polypectomy. Endoscopic mucosal resection (EMR) is performed to remove large laterally spreading colonic lesions that have a high risk of progression to CRC. Endoscopically invisible micro-adenomas at the margins of the EMR site might contribute to adenoma recurrence, which occurs in 15% to 30% of patients who undergo surveillance.
