Clinical Features and Prognostic Impact of Pancreatic Ductal Adenocarcinoma without Dilatation of the Main Pancreatic Duct: A Single-Center Retrospective Analysis.

The presence of main pancreatic duct (MPD) dilatation is important for diagnosing pancreatic ductal adenocarcinomas (PDACs). However, we occasionally encounter PDAC cases without MPD dilatation. The objectives of this study were to compare the clinical findings and prognosis of pathologically diagnosed PDAC cases with and without MPD dilatation and to extract factors related to the prognosis of PDAC.

Complications of Non-Alcoholic Fatty Liver Disease in Extrahepatic Organs.

Non-alcoholic fatty liver disease (NAFLD) is now recognized as the most common chronic liver disease worldwide, along with the concurrent epidemics of metabolic syndrome and obesity. Patients with NAFLD have increased risks of end-stage liver disease, hepatocellular carcinoma, and liver-related mortality. However, the largest cause of death among patients with NAFLD is cardiovascular disease followed by extrahepatic malignancies, whereas liver-related mortality is only the third cause of death.

Clinical features of isolated proximal-type immunoglobulin G4-related sclerosing cholangitis.

Background And Aim: Immunoglobulin G4-related sclerosing cholangitis (IgG4-SC) presents as isolated proximal-type sclerosing cholangitis (i-SC). The present study sought to clarify the imaging differences between i-SC and Klatskin tumor. Differences between i-SC and IgG4-SC associated with autoimmune pancreatitis (AIP-SC) were also studied.

[Successful endoscopic ultrasound-guided cyst drainage (EUS-CD) of pancreatic pseudocyst in the abdominal cavity to the cervical region accompanied by spontaneous rupture into the portal vein:a case study].

A 53-year-old man was admitted to our hospital with the complaint of neck pain and dyspnea. His blood examination revealed increased C-reactive protein and amylase levels. Enhanced computed tomography (CT) images demonstrated a retropharyngeal and a mediastinal low-density area extending to the portal area.
