A 51-year-old man with no relevant medical history presents to the emergency department complaining of a recent worsening of few months upper abdominal pain with back radiation and postprandial fullness, without B symptoms. Laboratory analysis showed hyperamylasaemia, elevated lactate dehydrogenase and inflammatory parameters. Abdominal ultrasonography revealed a heterogeneous solid mass in the spleen/splenic hilum with pancreatic parenchyma continuity and no biliary tract dilation or gallstones. A mild acalculous acute pancreatitis diagnosis was made...

Double balloon enteroscopy (DBE) is an endoscopic technique broadly used to diagnose and treat small bowel diseases. Among the associated complications of the oral DBE, post-procedure pancreatitis has taken the most attention due to its gravity and the thought that it might be associated to the technique itself and anatomical features of the pancreas. However, as the etiology has not been clarified yet, this paper aims to review the published literature and adds new results from a porcine animal model. Biochemical markers, histological sections and the vascular perfusion of the pancreas were monitored in the pig during DBE practice...

BACKGROUND: Acute necrotizing pancreatitis (ANP) is complicated with segmental portal hypertension (PHT) and formation of venous collaterals. Presence of collaterals in vicinity of endoscopic transmural tract can lead to potentially catastrophic situation. Here, we report safety and outcome of EUS-guided transmural drainage of walled-off pancreatic necrosis (WOPN) in patients with PHT and intra-abdominal collaterals. METHODS: Retrospective analysis of collected database of patients (n=18; age 40...

BACKGROUND/AIMS: Glucose-stimulated insulin secretion (GSIS) of pancreatic β-cells involves glucose uptake and metabolism, closure of KATP channels and depolarization of the cell membrane potential (Vmem), activation of voltage-activated Ca2+ currents (ICav) and influx of Ca2+, which eventually triggers hormone exocytosis. Beside this classical pathway, KATP-independent mechanisms such as changes in intracellular pH (pHi) or cell volume, which also affect β-cell viability, can elicit or modify insulin release...

The pancreatic pseudocyst is a pancreatic fluid collection which classically develops due to acute or chronic pancreatitis. A 68-year-old male with the remote history of alcohol abuse presented with abdominal pain secondary to acute pancreatitis. The first computed tomography (CT) of the abdomen showed acute necrotizing pancreatitis. He was initially treated conservatively. Repeat CT of the abdomen after two weeks revealed a peripancreatic fluid collection of 20x12x10 cm. One month later, he became septic following biliary stent placement...

Pancreatic anaplastic carcinoma (PAC) is rare and has an aggressive clinical course. We report an autopsy case of PAC focusing on the cytopathological characteristics of the tumor and immunocytochemical staining for vimentin, E-cadherin, and zinc finger E-box binding homeobox 1 (ZEB1), which markers are associated with epithelial markers of epithelial-mesenchymal transition (EMT). A 50-year-old woman presented to our hospital with a chief complaint of jaundice. A pancreatic head tumor and multiple liver nodules were detected on abdominal computed tomography...

Background: Non-invasive tumor characterization and monitoring are among the key goals of medical imaging. Using hyperpolarized (13)C-labelled metabolic probes fast metabolic pathways can be probed in real-time, providing new opportunities for tumor characterization. In this in vitro study, we investigated whether measurement of apparent diffusion coefficient (ADC) measurements and magnetic resonance spectroscopy (MRS) of co-polarized (13)C-labeled pyruvic acid and fumaric acid can non-invasively detect both necrosis and changes in lactate export, which are parameters indicative of tumor aggressiveness...

Isolated internal carotid artery (ICA) thrombus in the absence of underlying atherosclerotic disease is a rare entity. We report a case of a patient presenting with right arm weakness, slurred speech, and altered mental status in the setting of acute on chronic pancreatitis. The patient was found to have scattered left cerebral hemisphere cortical infarctions, and catheter angiography confirmed the presence of intraluminal left ICA thrombus, with no evidence of atherosclerotic disease in the cervical or intracranial vasculature...

Spontaneous pancreaticoduodenal fistulization and arterial psuedoaneurysm formation are both complications of acute pancreatitis. We present a 27-year-old man with hematemesis who was found to be bleeding from a gastroduodenal artery psuedoaneurysm through a spontaneous pancreaticoduodenal fistula as a result of severe alcohol-related necrotizing pancreatitis. This is the first reported case in the literature to describe this occurrence.

Hemosuccus pancreaticus is a rare cause of gastrointestinal bleeding in which haemorrhage occurs from the ampulla of vater via the pancreatic duct, mostly from ruptured pseudoaneurysms. Our patient is a 25-year-old Filipino male who presented with intermittent epigastric pain associated with melena and decreasing haemoglobin despite multiple blood transfusions. EGD showed erythematous gastric and duodenal mucosa with no evidence of active bleeding. Whole abdominal CT scan with IV contrast showed diffusely prominent pancreas with areas of non-enhancement suggestive necrosis...

Lethal necrotizing pancreatitis postpartum due to primary hyperparathyroidism caused by a parathyroid adenoma can be considered as a rarity. Due to the unspecific clinical signs and uncommonness this disorder may be overseen very easily. The reported case illustrates the very importance of early diagnosis of this endocrine disorder in pregnancy in order to avoid a lethal course.

BACKGROUND: Type 1 diabetes is an autoimmune disease that destroys insulin-producing beta cells in the pancreas. Pancreatic islet transplantation could be an effective treatment option for type 1 diabetes once several issues are resolved, including donor shortage, prevention of islet necrosis and loss in pre- and post-transplantation, and optimization of immunosuppression. This study seeks to determine the cause of necrotic loss of isolated islets to improve transplant efficiency. METHODOLOGY: The oxygen tension inside isolated human islets of different sizes was simulated under varying oxygen environments using a computational in silico model...
