Ghrelin influences pancreatic endocrine and exocrine functions, regulates intracellular calcium [Ca2+]i levels, and has an anti-inflammatory role in acute pancreatitis. This study investigated the role of endogenous ghrelin in the expression of Cav 1.2 (L-type of Ca2+ channel) and Cav 2.2 (N-type of Ca2+ channel) in acute pancreatitis. For this purpose, acute edematous pancreatitis (AEP) and acute necrotizing pancreatitis (ANP) rat models were established. Cav 1.2 and Cav 2.2 expression was assessed by immunohistochemistry in the pancreatic tissues of rats; ghrelin, interleukin-1β (IL-1β) and tumor necrosis factor-α (TNF-α) serum levels were detected using ELISA...

The present case study documents an autopsy case of granulocyte-colony stimulating factor (G-CSF)-producing mucinous cystic neoplasm (MCN), with an associated invasive carcinoma of the pancreas. A 65-year-old woman presented to Omuta City Hospital (Omuta Japan) with a primary complaint of abdominal pain. Multiple liver nodules and a pancreatic cyst were detected upon abdominal computed tomography. Initially, liver abscess was suspected as the patient exhibited leukocytosis and elevated C-reactive protein level...

Transarterial chemoembolization (TACE) with drug-eluting beads (DC beads) may enhance drug delivery to tumours and reduce systemic toxicity. TACE with DC beads leads to significantly fewer serious side-effects compared with conventional TACE. A 66-year-old man with hepatocellular carcinoma (HCC) complained of continuous abdominal pain 1 month after TACE with DC beads. At the time of TACE, angiography revealed severe stenosis of both hepatic arteries. The diagnostic work up on admission suggested severe bile duct injury with regional bile duct dilatation, segmental liver and spleen infarction, necrotizing pancreatitis, as well as gastric and duodenal ulcers...

Pancreatic glandular necrosis is rapid inflammation of the pancreas and contributes to severe acute pancreatitis in humans. The pathogenesis of pancreatic tissue inflammation during acute pancreatitis is still largely unknown. Recent studies suggest that 5-lipoxygenase (5-LOX) is an essential mediator in modulating cell death pathways in human diseases. In this study, we aimed to evaluate the effects of a 5-LOX inhibitor, zileuton, on tissue apoptosis and neutrophils activation in pancreatic tissues during acute necrotizing pancreatitis (ANP) in a rat model...

Anaplastic carcinoma spindle cell type is an extremely rare disease and its prognosis is very poor. We herein report a case of anaplastic carcinoma spindle cell type of the pancreas. A 50-year-old man complaining of epigastralgia was found to have a pancreatic body-tail tumor by abdominal US and CT studies. Abdominal CT showed an irregular poorly-enhanced 33mm tumor containing a cystic component. ERCP revealed the main pancreatic duct was cut off at the tumor. Cytology of the pancreatic fluids did not indicate malignancy...

Necrotizing pancreatitis remains a challenging and unpredictable condition accompanied by various complications. Endoscopic ultrasound-guided transmural drainage and necrosectomy have become the standard treatment for patients with walled-off necrosis (WON). Endoscopic therapy via lumen-apposing metal stents (LAMS) with large diameters has shown success in the management of pancreatic fluid collections, but there are few data on specific complications of that therapy. We report a case of infected WON and concomitant fungemia following LAMS placement and necrosectomy...

A 70-year-old male was referred to our hospital because of weight loss and epigastric discomfort. CT showed an irregularshaped, low-density tumor, 12 cm in diameter in the tail of the pancreas. This tumor widely invaded to the left kidney and to the anterior and left lateral sides of the aorta in spite of no involvement of celiac and superior mesenteric arteries. Moreover, it closely contacted with the stomach and the spleen. EUS-fine-needle aspiration biopsy of the tumor detected adenocarcinoma. Thus, he was diagnosed with UR-LA pancreatic cancer with aortic invasion...

In the "proton pump inhibitors era", a penetrating peptic ulcer (PPU) represents an exceptional cause of abdominal pain, and was more frequently observed in the past where there was not an effective antacid treatment. Ulcer-induced pancreatitis is very rare, too, and manifests with persistent, intense pain radiating to the back. A mild to severe pancreatitis with peripancreatic fluid collection can be observed at imaging. However, only a few cases of association between PPU and emphysematous pancreatitis (EP) have been published in the literature...

RATIONALE: Cerebral aspergillosis (CA) is a rare manifestation of invasive aspergillosis. It usually affects seriously immunocompromised hosts. Pancreatic bacterial or/and fungal infection is common in patients with severe acute pancreatitis. PATIENT CONCERNS: We report the first case of an immunocompetent woman with infected necrotizing pancreatitis due to multidrug resistant Acinetobacter baumannii who, in the course of treatment, developed isolated CA. DIAGNOSES: Magnetic resonance imaging, rather than computed tomography, revealed latent homolateral sinus disease-the possible source of the Aspergillus infection...

OBJECTIVE: The most common aetiologies of acute pancreatitis (AP) are gallstones, alcohol and idiopathic. The impact of the aetiology of AP on the extent and morphology of pancreatic and extrapancreatic necrosis (EXPN) has not been clearly established. The aim of the present study was to assess the influence of aetiology on the presence and location of pancreatic necrosis in patients with AP. PATIENTS AND METHODS: We carried out a post-hoc analysis of a previously established multicentre cohort of patients with AP in whom a computed tomography was available for review...

BACKGROUND: The clinical impact of hypoxia in solid tumours is indisputable and yet questions about the sensitivity of hypoxia-PET imaging have impeded its uptake into routine clinical practice. Notably, the binding rate of hypoxia-sensitive PET tracers is slow, comparable to the rate of diffusive equilibration in some tissue types, including mucinous and necrotic tissue. This means that tracer uptake on the scale of a PET imaging voxel-large enough to include such tissue and hypoxic cells-can be as much determined by tissue transport properties as it is by hypoxia...

Most patients with acute pancreatitis will develop edematous pancreatitis with a mild course and spontaneous resolution within several days to a few weeks. However, about 20% of patients will develop necrotizing pancreatitis, which carries a high mortality. This case report focuses on a patient with infected necrosis of the pancreas, which is managed with endoscopic transluminal debridement, a safe alternative to open surgery.
