Interventional EUS-guided cholangiography: evaluation of a technique in evolution

Gastrointestinal Endoscopy
Michel KahalehPaul Yeaton


Interventional EUS-guided cholangiography (IEUC) has been increasingly used as an alternative to percutaneous transhepatic cholangiography (PTC) in cases of biliary obstruction when ERCP is unsuccessful. We reviewed our experience and technique used for this procedure. Over a 3-year period, ending July 2005, patients with a failed ERCP were offered an IEUC. Tertiary care center offering ERCP and interventional EUS. Twenty-eight patients were candidates for IEUC. Two patients had bleeding masses and were referred to interventional radiology, 1 patient had a large mass occupying the duodenal lumen, and 2 patients refused IEUC. EUS was used to access the biliary system after which a guidewire was advanced antegrade across the obstruction. Either rendezvous with retrograde or antegrade drainage was then accomplished. Efficacy and safety of IEUC for biliary decompression. IEUC was successfully performed in 23 patients, with a transgastric-transhepatic (intrahepatic) approach in 13 cases and transenteric-transcholedochal (extrahepatic) approach in 10 cases. Therapeutic benefit was achieved in 21 patients: 18 underwent successful stent deployment across the stricture, whereas 3 patients required a choledochoenteric fistula formation. ...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.
