Pretest prediction and diagnosis of metastatic lesions to the pancreas by endoscopic ultrasound-guided fine needle aspiration.
Early diagnosis of solid pancreatic lesions (SPLs) enables prompt treatment. The study aims to identify factors differentiating metastatic lesion to the pancreas (PMET) from pancreatic ductal adenocarcinoma (PDAC) and pancreatic neuroendocrine tumors (PNETs). ⋯ Among the largest numbers of neoplastic SPLs evaluated at a single center, pre-test features reliably characterize, and EUS-FNA provides a highly specific diagnosis of PMETs.

Randomized Controlled TrialComparison of clipping with and without epinephrine injection for the prevention of post-polypectomy bleeding in pedunculated colon polyps.
Post-polypectomy bleeding (PPB) is the most common adverse event of colonoscopic polypectomy, especially in cases with large pedunculated polyps. To minimize the risk of PPB, several endoscopic preventive methods have been performed. The aim of this prospective, randomized study was to compare the rates of PPB following single (clipping alone) and combined (clipping plus epinephrine-saline injection) methods in prevention of PPB in large pedunculated polyps. ⋯ The rate of IPPB is relatively high in cases with large pedunculated polyps, but these polyps can be successfully resected by snare polypectomy following use of the single prophylactic clipping method.
