Abstract

Surgical gastrojejunostomy is associated with relatively high morbidity and mortality rates. However, current experimental EUS-guided gastrojejunostomy information is limited. To evaluate a novel EUS-guided gastrojejunostomy technique using a new enteric balloon and lumen-apposing metal stent. Animal experiment. Animal laboratory at a referral center. In 5 pigs, gastrojejunostomies were created under EUS guidance. Fully covered lumen-apposing stents were placed between the stomach and the jejunum. Technical success and adverse events of EUS-guided gastrojejunostomy. All stents, with 1 exception, were successfully deployed without any adverse events. The mean time to stent placement was 44.2 minutes (range 28-64 minutes). All animals showed normal eating behavior without signs of infection for 1 month after the procedure. Endoscopic imaging of the stomach site showed the stent to be patent and stable, without dislodgment, in all of the pigs. Necropsy showed complete adhesion between the stomach and the jejunum wall. Pilot study. Creation of an EUS-guided gastrojejunostomy by using a novel enteric balloon and metal stent appears to be promising as a minimally invasive treatment.

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.

Bone Marrow Neoplasms

Bone Marrow Neoplasms are cancers that occur in the bone marrow. Discover the latest research on Bone Marrow Neoplasms here.

IGA Glomerulonephritis

IgA glomerulonephritis is a chronic form of glomerulonephritis characterized by deposits of predominantly Iimmunoglobin A in the mesangial area. Discover the latest research on IgA glomerulonephritis here.

Cryogenic Electron Microscopy

Cryogenic electron microscopy (Cryo-EM) allows the determination of biological macromolecules and their assemblies at a near-atomic resolution. Here is the latest research.

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.

LRRK2 & Immunity During Infection

Mutations in the LRRK2 gene are a risk-factor for developing Parkinson’s disease. However, LRRK2 has been shown to function as a central regulator of vesicular trafficking, infection, immunity, and inflammation. Here is the latest research on the role of this kinase on immunity during infection.

Antiphospholipid Syndrome

Antiphospholipid syndrome or antiphospholipid antibody syndrome (APS or APLS), is an autoimmune, hypercoagulable state caused by the presence of antibodies directed against phospholipids.

Meningococcal Myelitis

Meningococcal myelitis is characterized by inflammation and myelin damage to the meninges and spinal cord. Discover the latest research on meningococcal myelitis here.

Alzheimer's Disease: MS4A

Variants within membrane-spanning 4-domains subfamily A (MS4A) gene cluster have recently been implicated in Alzheimer's disease by recent genome-wide association studies. Here is the latest research.
