The purpose of this article is to compare the technical success and guidance of percutaneous transhepatic biliary drainage (PTBD) in patients with nondilated and dilated bile duct systems using different techniques to supplement the conventional approach. Between 2006 and 2008, 71 patients (mean age, 66.6 years) underwent PTBD with 97 interventions. According to sonographic evaluation of bile duct morphology, patients were divided into two groups: 50 patients with dilated and 21 patients with nondilated bile ducts. In a retrospective analysis, both groups were compared for technical success, fluoroscopy time, complications, and medical indications. The use of interventional guidance (deviations from the standard protocol) in patients with nondilated bile ducts was recorded. The technical success rate was 90% in patients with dilated bile ducts versus 81% in patients with nondilated ducts, with no significant difference (p = 0.36). The greater complexity of the intervention in patients with nondilated bile ducts resulted in longer fluoroscopy times (p = 0.04). Complication rates were not different between the two groups. The main indication for PTBD was relief of a compressed biliary system in patients with dilated ducts and pos...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.

Head And Neck Squamous Cell Carcinoma

Squamous cell carcinomas account for >90% of all tumors in the head and neck region. Head and neck squamous cell carcinoma incidence has increased dramatically recently with little improvement in patient outcomes. Here is the latest research on this aggressive malignancy.

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.
