Normal and anomalous pancreaticobiliary union in children and adolescents

Gastrointestinal Endoscopy
M GuelrudD Jaén


The normal length of the pancreaticobiliary union (common channel) in the pediatric population is not known, nor is the frequency of anomalous pancreaticobiliary union and the extent to which it is associated with pancreaticobiliary disease. ERCP was performed on 136 patients younger than 1 year (group 1) and 128 older than 1 year (group 2). In group 1 the average length of the common channel was 1.8 +/- 0.61 mm with a maximal length of 3 mm (mean plus 2 standard deviations). In group 2 the average length and maximal length of the common channel increased with age. In the 1 to 3 year age range the average length was 2.2 +/- 0.47 mm with a maximal length of 2.7 mm, in the 4 to 6 year range it was 2.8 +/- 0.40 mm (3.6 mm maximal), in the 7 to 9 year range it was 3.2 +/- 0.43 mm (4.1 mm maximal), in the 10 to 12 year range it was 3.9 +/- 0.5 mm (4.4 mm maximal), and in the 13 to 15 year range it was 4.0 +/- 0.51 mm (5 mm maximal). The prevalence of the anomalous pancreaticobiliary union was 25% (66/264). In group 1 the anomaly was present in 4.4% (6 of 136) of patients, 1.3% (1/76) with neonatal hepatitis, 4.6% (3/44) with biliary atresia, and 100% (2/2) with choledochal cyst. In group 2 the anomaly was present in 46.9% (60/128) o...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.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

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.


Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
