Abstract

The purpose of this study is to investigate the technical and clinical efficacy of percutaneous bilateral stent-in-stent deployment using open cell-design stents and to compare the clinical outcomes of bilateral stent placement using T and Y configurations. From January 2006 to December 2010, 106 patients with malignant hilar biliary obstruction (Bismuth type II or higher) were included in this retrospective study. All patients were treated with percutaneous bilateral stent-in-stent deployment using open cell-design stents (64 in a T configuration and 42 in a Y configuration). Bilateral stent-in-stent deployment was technically successful in all patients. Seven patients (6.6%) had major complications, including one with severe hemobilia, two with acute cholecystitis, and four with cholangitis; seven (6.6%) patients had minor complications, including self-limiting hemobilia. Successful internal drainage was achieved in 94 patients (88.7%). Stent occlusion by tumor ingrowth, with or without overgrowth, occurred in 37 patients (34.9%). The median survival and stent patency times were 192 days (95% CI, 153.6-230.4 days) and 319 days (95% CI, 148.5-489.5 days), respectively. Stent configuration did not significantly affect technical...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Synthetic genetic arrays allow the systematic examination of genetic interactions. Here is the latest research focusing on synthetic genetic arrays and their analyses.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.
