Gastric ectopic pancreas presenting as a submucosal tumour accounts for approximately 11% of all endoscopic ultrasonography (EUS) examinations. Definitive diagnosis through endoscopy is difficult, even with EUS-guided fine-needle aspiration biopsy for histological examination. For symptomatic patients or those with uncertain diagnosis, complete surgical resection is the primary strategy for treatment and diagnosis. Herein, we report a case of gastric ectopic pancreas treated using robotic surgery.

BACKGROUND: Although fat accumulation in human organs is associated with a variety of diseases, there is little evidence about the effect of a fatty pancreas on the development of subclinical chronic pancreatitis over the clinical course. METHODS: We conducted a prospective cohort study from 2008 to 2014 of patients who underwent a medical checkup consultation for fat accumulated in the pancreas. Patients included in the analysis were divided into a non-fatty pancreas group (n = 9710) and fatty pancreas group (n = 223)...

Pancreatic granular cell tumors (GCTs) are rare and making an imaging diagnosis of pancreatic GCT is difficult because it has no definite characteristics on contrast-enhanced computed tomography (CE-CT) or magnetic resonance imaging (MRI) owing to varying findings. We report about a 32-year-old woman who presented with an incidental finding of a pancreatic tumor with a past history of excision of a right forearm GCT nodule 12 years ago. CE-CT revealed a 23-mm-sized homogeneous low enhancement tumor in the arterial phase in the pancreatic body...

Type 1 diabetes mellitus (T1DM) is characterized by hyperglycemia, owing to the loss of pancreatic β cells in response to an autoimmune reaction leading to a state of absolute insulin deficiency. T1DM treatment is shifting from exogenous insulin replacement therapy toward pancreatic β-cell replacement, to restore physiologically responsive insulin secretion to variations in blood glucose levels. β-cell replacement strategies include human whole pancreas transplantation, islet transplantation with cell encapsulation and bioengineered pancreas...

Ectopic pancreas is a rare embryological abnormality apparently not in association with others. Stomach and duodenum are the most common organs involved. Symptoms are nonspecific. Patients may complain of dyspepsia, abdominal pain or intestinal obstruction. Malignant evolution of ectopic pancreatic cells has been reported. Diagnosis can be very challenging due to the rarity of the disease and the absence of specific symptoms and radiological findings. We report two cases of young-adult men admitted to the emergency department due to acute upper gastro-intestinal and pancreatic symptoms...

Anaplastic lymphoma kinase (ALK)-positive anaplastic large cell lymphoma (ALCL) is a T cell subtype of non-Hodgkin's lymphoma (NHL). Typically, lymphoma rarely infiltrates vascular structure. In this article, we present a case of retroperitoneal ALK-positive ALCL with splenic venous tumor thrombosis. A 62-year-old patient presented to our institute with the symptoms of epigastric pain, abdominal distension, and reduced bowel movement. Physical examination indicated no enlarged peripheral lymph nodes or abdominal mass...

INTRODUCTION: Primary pancreatic lymphomas are extremely rare. Clinically, primary pancreatic lymphoma mimics symptoms of carcinoma of the pancreatic head. Clinical and radiological features may overlap with other pancreatic conditions such as carcinoma, neuroendocrine tumours and autoimmune pancreatitis. CASE REPORT: We report a case of a 75-year-old man who presented with symptoms of obstructive jaundice. Ultrasonography and computed tomography (CT) showed an ill-defined lobulated soft tissue lesion at the head/uncinate process of the pancreas measuring 4...

The pancreas is easily investigated in children thanks to the relative lack of fat tissue and the large left hepatic lobe with an optimal acoustic window. The use of high frequency, even linear transducers, usually results in detailed images of all pancreatic areas. A wide spectrum of pancreatic pathologic conditions can be identified and monitored at ultrasound although they are relatively uncommon during childhood compared to the adult. In this paper we briefly review the anatomy, technique, and sonographic aspects of normal and pathological pediatric pancreas...

BACKGROUND: Acute pancreatitis in dogs is an under-diagnosed disease. Current diagnostic methods are insufficient at identifying sequelae and lack prognostic capability. Computed tomographic angiography (CTA) is accurate for diagnosis and prognostication of pancreatitis in humans. OBJECTIVES: In comparison to ultrasound (US), CTA will (1) better diagnose more severe pancreatitis and sequelae and (2) provide assessment of patient outcome by identification of pancreatic contrast enhancement patterns...

BACKGROUND: Recently, laparoscopic distal pancreatectomy (LDP) has become the standard procedure for resection of left-sided pancreatic tumors. Fluid collection (FC) at the resection margin of the pancreatic stump after LDP is a frequent radiological finding. However, there have been few treatment guidelines and the optimal management for this clinical finding is unclear. The aim of present study is to define the incidence of FC and suggest the optimal management for FC after LDP. METHODS: A total of 1227 patients who underwent LDP between March 2005 and December 2015 were collected...

Background Ectopic visceral fat is a major risk factor for obesity complications including insulin resistance and metabolic syndrome. Ultrasonography is a simple bedside screening tool used for the assessment of ectopic visceral fat including fatty pancreas. This study investigates the association between insulin resistance, metabolic syndrome and fatty pancreas detected by ultrasound in children with obesity. Methods This case-control study included 50 prepubertal obese (body mass index [BMI] ≥95th age- and sex-specific percentiles) and 30 lean children (BMI 5th-85th age- and sex-specific percentiles) as the control 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...
