S16 ENDOSCOPIC ULTRASOUND / VOLUME 6 / SUPPLEMENT 1 / AUGUST 2017 for cases which require immunohistochemistry, for example, neuroendocrine tumor, lymphoma, and mediastinal tumors. (3) EUS is the most important tool for pancreatic cystic lesions. (4) EUS is an important tool for diagnosis of CBD and gallbladder masses. EUS gives accurate diagnosis in gastric submucosal lesions, infiltrative gas...

Objective(s): This study was designed to assess defect detectability in positron emission tomography (PET) imaging of abdominal lesions. Methods: A National Electrical Manufactures Association International Electrotechnical Commission phantom was used. The simulated abdominal lesion was scanned for 10 min using dynamic list-mode acquisition method. Images, acquired with scan duration of 1-10 mi...

PURPOSE The roles of intravisceral and subcutaneous fat are unknown, and the prevalence of precancerous lesions in obese patients was never evaluated. This study aims to assess the frequency and severity of pancreatic intraepithelial neoplasia (PanIN) and to correlate pathologic findings with metabolic abnormalities, type of fat, and fatty pancreatic infiltration. EXPERIMENTAL DESIGN Normal p...

BACKGROUND We postulated that the abundance of various metabolites in blood would facilitate the diagnosis of pancreatic and biliary lesions, which could potentially prevent unnecessary surgery. METHODS Serum samples from patients with benign hepatobiliary disease (n = 43) and from patients with pancreatic cancer (n = 56) were examined by ¹H NMR spectroscopy to quantify 58 unique metabolites....

PURPOSE With the advancement of laparoscopic techniques and instruments, laparoscopic approach for pancreatic lesions has become an increasingly used procedure. But, there are few and limited studies about laparoscopic enuleation (LE) for pancreatic lesions. Therefore, the purpose of this study was to present our experience and to evaluate the clinical outcome of LE for pancreatic benign or bor...

A 74-year-old male was admitted to Departments of Surgery, Toyonaka Municipal Hospital (Osaka, Japan) for treatment of a pancreatic tumor. Contrast enhanced computed tomography (CT) revealed a mass with small cystic lesions in the pancreatic head and body. Fluorodeoxyglucose-positron emission tomography/CT revealed an abnormal uptake of fluorodeoxyglucose, corresponding to the mass lesions. Upp...

Pancreatic cancer is almost invariably associated with mutations in the KRAS gene, most commonly KRASG12D, that result in a dominant-active form of the KRAS GTPase. However, how KRAS mutations promote pancreatic carcinogenesis is not fully understood, and whether oncogenic KRAS is required for the maintenance of pancreatic cancer has not been established. To address these questions, we generate...

Background: Most Pancreatic solid pseudopapillary tumors are asymptomatic and incidentally found by imaging. In some cases, patients may present with nonspecific symptoms, including abdominal discomfort, nausea, vomiting, or pain. Many of these lesions, located frequently in the body tail pancreas, require resection. Aim: My aim is to a case young female patient underwent laparoscopic subtotal ...

Pancreatic injuries include a variety of from simple contusion to complete rupture the duct and pancreatic head. Although lesions are rare in children, pseudocyst is most common posttraumatic cystic lesion pancreas localized collection containing juice peripancreatic necrotic test. The management has evolved stage exclusive surgical treatment exclusively, conservative one, respectively minimall...

Endoscopic ultrasonography (EUS) is widely used to evaluate pancreaticobiliary diseases, especially pancreatic masses. EUS has a good ability to detect pancreatic masses, but it is not sufficient for the differential diagnosis of various types of lesions. In order to address the limitations of EUS, new techniques have been developed to improve the characterization of the lesions detected by EUS...
