INTRODUCTION: Castleman disease (CD) is a rare polyclonal lymphoproliferative disorder of unknown etiology, which usually develops in the mediastinum. It can also occur in the cervical, retroperitoneal and axillary regions. Localized pancreatic CD is quite rare [1]. PRESENTATION OF CASE: The authors herein present a case of a 34 years old female that was diagnosed during a symptomatic cholelithiasis evaluation. During the evaluation, an abdominal ultrasonography revealed a tumor at the head of the pancreas, which went on to generate a dilatation of the extrahepatic bile ducts...

INTRODUCTION: The diagnosis and management of upper gastrointestinal tract submucosal tumours can be challenging due to the difficulties with adequate pre-operative characterization and tissue sampling. PRESENTATION OF THE CASE: A 61-year-old female patient underwent esophagogastroduodenoscopy because of epigastric pain and episodic vomiting. A submucosal tumour was found along the greater curvature in the antrum. On endoscopic ultrasound, the mass was suspected to be a gastrointestinal stromal tumour...

AIM: To determine whether fetal pancreatic echogenicity assessment is associated with gestational diabetes mellitus (GDM). METHODS: A prospective cross-sectional study was conducted in a cohort of 160 pregnant women with uncomplicated singleton pregnancies. Fetal ultrasonography was performed between 24 and 28 weeks of gestation for conventional fetal biometry. Based on their pancreatic sonogram results, subjects were divided into two groups ie hyperechogenic pancreas group and iso-moderate echogenic pancreas group...

Accumulated evidence has revealed that endoscopic ultrasonography (EUS) has had a great impact on the clinical evaluation of pancreatic cancers. EUS can provide high-resolution images of the pancreas with a quality regarded as far surpassing that achieved on transabdominal ultrasound (US), computed tomography (CT), or magnetic resonance imaging (MRI). EUS is particularly useful for the detection of small pancreatic lesions, while EUS and its related techniques such as contrast-enhanced EUS (CE-EUS), EUS elastography, and EUS-guided fine needle aspiration (EUS-FNA) are also useful in the differential diagnosis of solid or cystic pancreatic lesions and the staging (T-staging, N-staging, and M-staging) of pancreatic cancers...

A 37-year-old man had an asymptomatic 17-mm mass in the liver by health check with ultrasonography. Five years later, he was referred to our hospital because the mass was slightly enlarged with a peripancreatic lymph node. We performed endoscopic ultrasonography fine-needle aspiration (EUS-FNA) to evaluate a lymph node, but it showed amorphous eosinophilic material and eosinophilic infiltrate in necrotic tissue of toothpaste-like white specimen. However, we diagnosed as potentially malignant liver mass with lymph node metastasis because of 2-deoxy-2-(fluorine-18) fluorodeoxyglucose uptake...

BACKGROUND: Post-operative pancreatic fistulae (POPF) remain a major contributor to morbidity and mortality following pancreatic resection. Evidence for preoperative prediction of POPF based on cross-sectional imaging has not been systemically reviewed. This review aimed to determine whether preoperative imaging modalities can accurately predict the development of POPF. METHODS: A systematic review of major reference databases was undertaken, according to PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, up to May 2018...

Anastomotic stricture can occasionally cause repeated acute pancreatitis after partial resection of the pancreas such as pancreaticoduodenectomy or duodenum-preserving pancreatic head resection (DPPHR). Endoscopic ultrasonography-guided pancreatic duct drainage with an oblique-viewing echoendoscope has revealed feasibility and availability [1, 2], while that with a forward-viewing echoendoscope (FV-ES) has extremely been limited [3-5]. We herein describe the first case with pancreaticogastrostomy obstruction treated by direct recanalization with FV-ES...

Pancreatic Fluid Collection (PFC) develops as a result of acute pancreatitis, chronic pancreatitis, trauma, and postoperation. Although percutaneous drainage, surgery and Endoscopic Retrograde Panceatogram are used as conventional treatments in complicated PFC, the clinical course of PFC is unsatisfactory due to its clinical success rate and the risk of procedure-related complications. Endoscopic ultrasonography-guided transmural drainage of PFC is a safe and effective modality for the management of PFC, particularly in patients with pancreas necrosis...

Surgery is the only treatment method in pancreatic cancer. Unfortunately, metastatic diseases or invasion of the main vascular structures are observed in a majority of cases at the time of diagnosis; these structures originate from the body, neck, and tail of the pancreas and are considered inoperable. The first celiac artery resection for the treatment of cancer was described by Appleby in 1953. Here, we describe our hepatic artery reconstruction technique in a case with pancreatic body cancer. A 37-year-old male patient was admitted to our emergency department owing to syncope...

A 25-year-old man, with a retroperitoneal bulky mass invading the posterior pancreas head, was referred to investigate and treat his rapidly advancing disease. An endoscopic ultrasonography guided-fine needle aspiration biopsy (EUS-FNAB), performed the next day, and followed by immunostaining for human chorionic gonadotropin (hCG), led to a histological diagnosis of choriocarcinoma. An elevated level of serum hCG also supported the diagnosis. Systemic chemotherapy by etoposide and cisplatin was initiated within a week, with precautions taken to avoid tumour lysis syndrome and choriocarcinoma syndrome...

Endoscopic ultrasonography (EUS) has enabled therapeutic endoscopists to intervene on conditions that have otherwise not been accessible with conventional endoscopy. Inflammatory fluid collections of the pancreas that may benefit from drainage are often not identifiable without EUS. Furthermore, EUS may improve the safety of transmural drainage by allowing for the identification of intervening blood vessels and reducing the need for fluoroscopy, and is complemented by new devices that simplify the access and stent delivery process...

Gastrointestinal stromal tumors (GIST) typically appear as solid masses, and cystic formation is uncommon. Most stomach GISTs with cystic formation progress outside the gastric wall and are frequently misdiagnosed as epigastric cystic tumors derived from pancreas or liver. An asymptomatic 72-year-old male underwent esophagogastroduodenoscopy, which revealed a submucosal tumor (SMT), approximately 50 mm in diameter, at the anterior wall of the gastric angle. The SMT was very soft with positive cushion sign. Endoscopic ultrasonography and contrast-enhanced computed tomography revealed that the SMT was a cystic tumor with solid component...

Endoscopic methods are increasingly used in the diagnosis of cystic lesions of the pancreas. The two major endoscopic approaches are endoscopic ultrasonography (EUS) and transpapillary diagnosis. EUS-guided fine-needle aspiration cytology and EUS-guided fine needle-based confocal laser endomicroscopy have been used in the differential diagnosis of mucinous and non-mucinous pancreatic cysts. EUS is the most sensitive modality for detecting mural nodules (MN) in intraductal papillary mucinous neoplasms (IPMN)...

Choledochal cysts rarely present with acute pancreatitis. We report a patient with type I choledochal cyst(s) who had concomitant acute frank hemorrhagic pancreatitis. A 14-year-old male noted with a history of recurrent abdominal pain, fever and jaundice. Ultrasonography (US) of abdomen at the Emergency Department depicted distended gall bladder with wall thickening. Apparently dilated intrahepatic ducts (IHDs) and fusiform dilatation of the common bile duct (CBD), and mild dilatation of the pancreatic duct were also noted, suggesting a type I choledochal cyst( )...

OBJECTIVE: Fatty infiltration of the pancreas is a dominating feature in cystic fibrosis (CF). We evaluate the association between pancreatic fat content assessed by Dixon magnetic resonance imaging (MRI), pancreatic echogenicity at ultrasonography (US) and exocrine function in CF patients and healthy controls (HC). MATERIAL AND METHODS: Transabdominal US, pancreatic Dixon-MRI and diffusion-weighted imaging (DWI) were performed in 21 CF patients and 15 HCs. Exocrine function was assessed by endoscopic secretin test and fecal elastase...

BACKGROUND: Medullary carcinoma of the pancreas (MCP) is a rare malignant pancreatic tumor. The World Health Organization classification defines the tumor as a subtype of pancreatic ductal carcinomas. MCP is histologically characterized as having highly pleomorphic cells with syncytial morphology, expansive tumor growth, and necrosis. The pathogenesis and clinical course of MCP are largely unknown. Herein, we report an unusual case of MCP that was radiologically followed up for 9 years prior to surgical intervention...

Obesity, insulin resistance, and metabolic syndrome continue to increase in prevalence. Hypertriglyceridemia is commonly associated and represents a valuable marker of metabolic syndrome. An increase in subcutaneous fat deposition places patients at risk for visceral adipose deposition in sites such as the liver, heart, and pancreas. Pancreatic steatosis in the setting of metabolic syndrome is a rapidly emerging entity whose clinical spectrum remains to be defined. Hypertriglyceridemia is an accepted cause of acute pancreatitis but its role in chronic pancreatic injury remains to be explored...
