At present, balloon enteroscopy-assisted endoscopic retrograde cholangiopancreatography (ERCP) is the mainstay of therapy for benign biliary diseases in patients with surgically altered anatomy (SAA). Recently interventional endoscopic ultrasonography (EUS) techniques have been used for not only drainage procedure but also treatment procedure in such patients. This review aims to discuss details about interventional EUS techniques in such patients and published clinical data. Antegrade treatment such as antegrade stone removal for bile duct stones or guidewire manipulation across the anastomotic stricture following antegrade balloon dilation and antegrade stenting for the stricture via the approach route created by EUS-bilioenterostomy, so-called EUS-guided antegrade intervention, have been developed. In difficult cases, per-oral cholangioscopy-assisted antegrade intervention has been reported as a useful technique. In addition, other novel alternative interventional EUS techniques have been also reported such as EUS-directed transgastric ERCP in patients with Roux-en-Y gastric bypass. Interventional EUS techniques appear to be feasible and safe alternative procedures for benign biliary diseases in patients with SAA after ballo...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.

Synthetic Genetic Array Analysis

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.

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.
