What is the Impact of the Proportion of Solid Necrotic Content on the Number of Necrosectomies during EUS-Guided Drainage using Lumen-Apposing Metallic Stents of Pancreatic Walled-off Necrosis ?

Background And Aims: The fully-covered, lumen apposing metal stents are designed for one step placement, facilitating the direct endoscopic necrosectomy into the walled-off pancreatic necrosis. However, the prediction of the number of necrosectomy sessions in these patients is not known. This study evaluated the association between the proportion of solid necrotic material inside walled-off necrosis, as assessed during the endosonography placement of a lumen apposing metal stent, and the number of necrosectomies subsequently required.

Are plasma lipid levels related to ABCG5/ABCG8 polymorphisms? A preliminary study in siblings with gallstones.

Background: The role of ABCG5 and ABCG8 genes in the determination of plasma lipid levels is currently under intensive investigation. The aim of this study was to evaluate plasma lipid levels in sibling pairs with gallstones and to assess their correlation with common gene polymorphisms in the ABCG5/ABCG8 genes.

Methods: Plasma levels of cholesterol, HDL-cholesterol, and triglycerides were measured in 68 patients belonging to 34 sibling pairs with gallstones (affected sibling pairs, mean age 56.
