Endoscopic ultrasound (EUS)-guided biliary drainage (EUSBD) with plastic stents has been introduced as an alternative to percutaneous transhepatic biliary drainage (PTBD) in cases of biliary obstruction when endoscopic retrograde cholangiopancreatography (ERCP) is unsuccessful. Although self-expandable metallic stents with a larger diameter might offer long-lasting patency compared with plastic stents, to date, EUSBD with one-step placement of a fully covered self-expandable metal stent (FCSEMS) has not been evaluated. We conducted this study to determine the feasibility and usefulness of EUSBD with one-step placement of FCSEMS. A prospective feasibility study on EUSBD with one-step placement of FCSEMS was carried out in 14 patients with malignant biliary obstruction who were candidates for alternative techniques for biliary decompression because of unsuccessful ERCP. The technical and functional success rate was 100% (14/14). Nine patients were treated using the intrahepatic approach. The remaining five patients were treated using the extrahepatic approach. With the intrahepatic approach, two patients showed self-limited pneumoperitoneum. With the extrahepatic approach, no patients had pneumoperitoneum. No bile peritonitis or ...Continue Reading

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.

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.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.
