Artificial intelligence for the detection of pancreatic lesions.

Purpose: Pancreatic cancer is one of the most lethal neoplasms among common cancers worldwide, and PCLs are well-known precursors of this type of cancer. Artificial intelligence (AI) could help to improve and speed up the detection and classification of pancreatic lesions. The aim of this review is to summarize the articles addressing the diagnostic yield of artificial intelligence applied to medical imaging (computed tomography [CT] and/or magnetic resonance [MR]) for the detection of pancreatic cancer and pancreatic cystic lesions.

Early gastric cancer and Artificial Intelligence: Is it time for population screening?

Gastric cancer is a common cause of death worldwide and its early detection is crucial to improve its prognosis. Its incidence varies throughout countries, and screening has been found to be cost-effective at least in high-incidence regions. Identification of individuals harbouring preneoplastic lesions and their surveillance or of those with early gastric cancer are extremely important processes and endoscopy play a key role for this purpose.

Endoscopy-Related Bleeding and Thromboembolic Events in Patients on Direct Oral Anticoagulants or Vitamin K Antagonists.

Background & Aims: Few prospective studies have assessed the safety of direct oral anticoagulants (DOACs) in elective endoscopy. Our primary aim was to compare the risks of endoscopy-related gastrointestinal bleeding and thromboembolic events in patients on DOACs or vitamin K antagonists (VKAs) in this setting. Secondarily, we examined the impact of the timing of anticoagulant resumption on the risk of delayed bleeding in high-risk therapeutic procedures.

Long-term follow-up after endoscopic submucosal dissection of colorectal lesions in a Spanish cohort.

Introduction: ESD in the colon is an increasingly important technique in Western countries. There are few studies that include long term follow-up.

Aim: to analyze the long term recurrence free survival rate after ESD and to compare recurrence rates according to different variables.

Endoscopic submucosal dissection for gastric epithelial lesions: long-term results in a Spanish cohort.

Introduction: endoscopic submucosal dissection for gastric lesions (ESD-G) is a technique that allows en-bloc resection of early gastric tumors, with a cure rate similar to that of surgery but lower morbidity and mortality rates.

Objective: to assess total survival, disease-free survival and relapse rate during the course of disease in a Spanish cohort of patients undergoing ESD-G.

Material And Methods: this was a prospective observational study of patients undergoing ESD-G from 2008 to 2015, with a follow-up ranging from six to 60 months.

[Acute liver ischaemia after gastro-oesophageal variceal bleeding].

Introduction: Variceal upper gastrointestinal bleeding (UGIB) can trigger acute hypoxic hepatitis (AHH). The aim of this study was to analyse the incidence, associated risk factors and mortality of AHH after variceal UGIB.

Patients And Methods: Retrospective study of cirrhotic patients with variceal UGIB, classified into 2 groups according to the development of AHH.

[Is it possible to stop treatment with nucleos(t)ide analogs in patients with e-antigen negative chronic hepatitis B? Experience and new expectations].

Background: Treatment of HBeAg-negative chronic hepatitis B (CHB) with nucleos(t)ide analogues (NA) is usually indefinite, since the loss of HBsAg, as a criterion for its discontinuation, is a rare event. Recent evidence suggests that discontinuing NA therapy may be feasible in selected patients.

Objectives: To analyze the rate of virological relapse in patients with HBeAg-negative CHB who discontinued treatment with NAs.
