BACKGROUND AND AIM Cholecystectomy and endoscopic retrograde cholangiopancreatography are the gold standard for managing acute cholecystitis and malignant biliary obstruction, respectively. Recent advances in therapeutic endoscopic ultrasound (EUS) have provided alternatives for managing patients in whom these approaches fail, namely, EUS-guided gallbladder drainage (EUS-GB) and EUS-guided bile duct drainage (EUS-BD). We aimed to assess the technical and clinical success of these techniques in t...

BACKGROUND Endoscopic surveillance for dysplasia in Barrett's esophagus with random biopsies is the primary diagnostic tool for monitoring clinical progression into esophageal adenocarcinoma. As an alternative, narrow-band imaging (NBI) endoscopy offers targeted biopsies that can improve dysplasia detection. AIM To evaluate NBI-guided targeted biopsies' diagnostic accuracy for detecting dysplasia in patients undergoing endoscopic BE surveillance compared to the widely used Seattle protocol. METH...

Background and Aim: Telehealth has become the standard of care during the COVID-19 outbreak This study aimed to assess doctor and patient satisfaction of endoscopy-related telehealth clinics with video consultations Methods: A prospective observational study of patients consecutively booked to attend two endoscopy-related telehealth clinics at an ambulatory tertiary care setting was conducted from July to October 2020 Data collected from our previously published study using phone consultations (...

In this paper, we propose and analyse a system that can automatically detect, localise and classify polyps from colonoscopy videos. The detection of frames with polyps is formulated as a few-shot anomaly classification problem, where the training set is highly imbalanced with the large majority of frames consisting of normal images and a small minority comprising frames with polyps. Colonoscopy videos may contain blurry images and frames displaying feces and water jet sprays to clean the colon -...

Esophageal cancer consistently ranks amongst the top ten cancer killers in the world and appears to be increasing in incidence. There are mainly two histology subtypes of esophageal cancer, derived either from squamous or glandular epithelium of the esophagus. Although they have different biological behaviors and contributing factors, both of these can be diagnosed by endoscopy imaging at an early stage. In order to maximize the chances for cure, a thorough and precise diagnosis of superficial n...

As in the rest of the gastrointestinal (GI) tract, Endoscopic Mucosal Resection (EMR) and Endoscopic Submucosal Dissection (ESD) techniques are used to address premalignant lesions and early cancers in the esophagus. The latter has been described as one of the most complex interventional procedures in endoscopy to date. Even though the technique of ESD shares common ground throughout the GI tract, there are some nuances to esophageal ESD based mainly on anatomical differences between different l...

Background and aim Pancreatic cancer (PC) carries a poor prognosis and is often detected at later stages. Screening programs for moderate- and high-risk people are still under debate. We present the results from a prospective study on endoscopic ultrasound (EUS) as a one-off screening tool for pancreatic cancer screening. Methods Asymptomatic patients with moderate- or high-risk of PC were invited to participate. Moderate risk consisted of one first-degree and at least one second-degree relative...

BACKGROUND AND AIM: During COVID-19 outbreak, restrictions to in-person consultations were introduced with a rise in telehealth. An indirect benefit of telehealth could be better attendance. This study aimed to assess "failure-to-attend" (FTA) rate and satisfaction for two endoscopy-related compulsory telehealth clinics during the COVID-19 outbreak. METHODS: Consecutive patients booked for endoscopy-related telehealth clinics at a tertiary hospital were prospectively assessed. In-person clinic c...

Anomaly detection methods generally target the learning of a normal image distribution (i.e., inliers showing healthy cases) and during testing, samples relatively far from the learned distribution are classified as anomalies (i.e., outliers showing disease cases). These approaches tend to be sensitive to outliers that lie relatively close to inliers (e.g., a colonoscopy image with a small polyp). In this paper, we address the inappropriate sensitivity to outliers by also learning from inliers. ...
