Artificial Intelligence in Monitoring Inflammatory Bowel Disease
Crohn’s disease and ulcerative colitis remain debilitating disorders, characterized by progressive bowel damage and possible lethal complications. The growing number of applications for artificial intelligence in gastrointestinal endoscopy has already shown great potential, especially in the field of neoplastic and pre-neoplastic lesion detection and characterization, and is under evaluation in the field of inflammatory bowel disease management. The application of artificial intelligence in inflammatory bowel diseases can range from genomic dataset analysis and risk prediction model construction to the disease grading severity and assessment of the response to treatment using machine learning.

Intestinal Tryptophan Metabolism in Inflammatory Bowel Disease
Evidence is emerging for the role of intestinal tryptophan metabolism in the development of inflammatory bowel disease (IBD). In order to identify the role of altered intestinal tryptophan metabolism in IBD pathogenesis, a meta-analysis of the transcriptome was performed to identify differentially expressed genes involved in the tryptophan metabolism pathways in intestinal biopsies of IBD as compared to non-IBD controls.

Virally Infected Donor Grafts
The ideal management for end stage liver disease, acute liver failure, and hepatocellular carcinoma (HCC), within specific criteria, is liver transplantation (LT). Due to continuous increase in LT cases, there has been consideration to increase utilization of organs from donor livers which were previously discarded, including virally infected donor livers.

Intestinal Microbiota and miRNA in IBD
Inflammatory bowel disease (IBD) includes Crohn’s disease (CD) and ulcerative colitis (UC) and comprises a chronic gastrointestinal tract disorder characterized by hyperactive and dysregulated immune responses to environmental factors, including gut microbiota and dietary components.

Direct Endoscopic Necrosectomy
Walled-off pancreatic necrosis (WOPN) is one of the local complications of acute pancreatitis (AP). Several interventional techniques have been developed over the last few years. The purpose of this entry is to explore such methodologies, with specific focus on endoscopic drainage and direct endoscopic necrosectomy (DEN), through evaluation of their indications and timing for intervention. Findings indicated how, after the introduction of lumen-apposing metal stents (LAMS), DEN is becoming the favorite technique to treat WOPN, especially when large solid debris or infection are present. Additionally, DEN is associated with a lower adverse events rate and hospital stay, and with improved clinical outcome.

Management of Cholestatic Liver Diseases
Primary biliary cholangitis (PBC) and primary sclerosing cholangitis (PSC) are two chronic cholestatic liver diseases affecting bile ducts that may progress to biliary cirrhosis.

Epigenetic Mechanisms in the Regulating of PPARγ Function
Contrary to genetic changes in heritability, epigenetics is the study of heritable modifications in gene activity that do not involve direct alteration of the underlying DNA sequences. Epigenetics determines the architecture of chromatin in cell nucleus, and therefore affects specific genomic sequences accessible to cellular regulatory machineries. The epigenome is susceptible to dysregulation throughout life but is highly vulnerable to environmental factors during fetal life since this is a period of rapid DNA synthesis.

Influence of Gut–Liver Axis on Portal Hypertension
Clinically significant portal hypertension is associated with most complications of advanced chronic liver disease (ACLD), including variceal bleeding, ascites, spontaneous bacterial peritonitis, hepatorenal syndrome, and hepatic encephalopathy. Gut dysbiosis is a hallmark of ACLD with portal hypertension and consists of the overgrowth of potentially pathogenic bacteria and a decrease in autochthonous bacteria; additionally, congestion makes the intestinal barrier more permeable to bacteria and their products, which contributes to the development of complications through inflammatory mechanisms within the gut–liver axis. The identification of the gut–liver liver-axis-related metabolic and molecular pathways may serve as a target for new therapeutic strategies through the modulation of the intestinal environment.

Physiopathology of Crohn’s Disease
Crohn’s disease (CD) is a severe chronic inflammatory disease of the gastrointestinal tract (GIT) with relapsing–remitting behavior. It is also called regional ileitis due to its frequent involvement of the ileum, which can occur anywhere in the GIT, being typically transmural.

Gastric Mucosal Atrophy for Predicting Gastric Cancer Risk
Patients suffering from chronic gastritis and developing gastric mucosa atrophy are at increased risk of the development of gastric cancer. The diagnosis of chronic atrophic gastritis (CAG) is a complex procedure involving a detailed history taking, a thorough physical examination and the use of laboratory and instrumental diagnostic methods among which the endoscopy of the upper digestive tract is the cornerstone because it allows the assessment of the topography of gastritis and identification of erosions and areas of intestinal metaplasia with the use of narrow band imaging (NBI) endoscopy. However, the diagnosis of CAG requires morphological examination of the gastric mucosa.
