Pancreatic Neuroendocrine Tumors and Management
The growing importance of advanced endoscopy in the diagnosis and treatment of pancreatic neuroendocrine neoplasms (PanNETs) necessitates a comprehensive understanding of various biochemical markers, genetic testing methods, radiological techniques, and treatment approaches that encompass multiple disciplines within and beyond gastrointestinal oncology.

Pancreatic Walled-off Necrosis Management
Necrotizing pancreatitis is a complex clinical condition burdened with significant morbidity and mortality. In recent years, the huge progress of interventional endoscopic ultrasound (EUS) has allowed a shift in the management of pancreatic necrotic collections from surgical/percutaneous approaches to mini-invasive endoscopic internal drainage and debridement procedures. The development of lumen-apposing metal stents (LAMSs), devices specifically dedicated to transmural EUS interventions, further prompted the diffusion of such techniques.

Pancreatitis in Pregnancy
Acute and chronic pancreatitis, until observed incidentally in pregnancy. Particularly severe complications for the mother and fetus may be a consequence of acute pancreatitis. Therefore, it is important to know more about the diagnostic and therapeutic possibilities of pancreatic diseases in the course of pregnancy.

Pathogenesis of Choledochal Cyst
Choledochal cysts (CC) is characterized by extra- and/or intra-hepatic b\ile duct dilations. There are two main theories, “pancreaticobiliary maljunction” and “congenital stenosis of bile ducts” proposed for the pathogenesis of CC. Although family cases or CC associated with other anomalies have been reported, the molecular pathogenesis of CC is still poorly understood. Advances in transcriptomics and genomics analysis platforms have unveiled key expression signatures/genes/signaling pathways in the pathogenesis of human diseases including CC.

Pathogenesis of Esophageal Cancer
Esophageal cancer is rapidly increasing across the world. It is the sixth most common cause of death from cancer and is the eighth most common cancer worldwide. Esophageal cancer is a devastating malignancy which can be detected at an early stage but is more often diagnosed as an advanced process. It affects both men and women and inflicts the young and the elderly. There are multiple underlying factors involved in the pathogenesis of this cancer including inflammation.

Pathogenesis of Hepatocellular Carcinoma
Hepatocellular carcinoma (HCC) is a very complex world health problem. Approximately 905,677 new cases and 830,180 HCC-related deaths were reported in 2020. The estimation of more than 1 million deaths caused by HCC by 2030 has been predicted. The pathogenesis of hepatocellular carcinoma (HCC) is a multifactorial process that has not yet been fully investigated.

Pathogenesis of Iron Overload and Hepatocellular Carcinoma
Hepatocellular carcinoma (HCC) is one of the most common malignancies in both transfusion-dependent thalassemia (TDT) and non-transfusion-dependent thalassemia (NTDT). The mechanisms of iron-overloading-associated HCC development include the increased reactive oxygen species (ROS), inflammation cytokines, dysregulated hepcidin, and ferroportin metabolism.

Pathological Conditions with Excessive Hepatic Glycogen Accumulation
The liver is a major store of glycogen and is essential in maintaining systemic glucose homeostasis. In healthy individuals, glycogen synthesis and breakdown in the liver are tightly regulated. Abnormal glycogen metabolism results in prominent pathological changes in the liver, often manifesting as hepatic glycogenosis or glycogen inclusions. This can occur in genetic glycogen storage disease or acquired conditions with insulin dysregulation such as diabetes mellitus and non-alcoholic fatty liver disease or medication effects. Excessive glycogen accumulation within hepatocytes occurs in diseases caused or accompanied by the dysregulation of carbohydrate metabolism, as well as in conditions not primarily driven by altered carbohydrate metabolism. In these pathological conditions, the excess glycogen is distinctly visible on H&E; the hepatocytes usually exhibit cytoplasmic pallor and rarefaction or may show cytoplasmic-glycogen-filled inclusion bodies. Some hepatocytes may also demonstrate glycogen-filled nuclear vacuoles without a delimiting membrane (“glycogenated nuclei”); these are frequently seen in patients with diabetes and obesity, although they can also be seen in other liver conditions such as Wilson’s disease.

Pathophysiological Mechanisms of Anemia in Chronic Liver Disease
Hematological abnormalities are frequently linked to chronic liver disease of any etiology. About 75% of patients with advanced chronic liver disease experience anemia. The causes of anemia are complex and multifactorial, particularly in cirrhotic patients.
