Precut fistulotomy for difficult biliary cannulation: is it a risky preference in relation to the experience of an endoscopist?

Digestive Diseases and Sciences

Several studies have reported on the correlation between the experience level of an endoscopist and the outcomes of precut procedures. However, there are limited data on the early use of the precut fistulotomy in relation to the experience of an endoscopist. To evaluate the efficacy and safety of precut fistulotomy in difficult biliary cannulation after ERCP training. Two endoscopists, one at each tertiary referral center, performed the precut fistulotomy for difficult biliary cannulation between September 2008 and February 2010. The technical success, complications, and clinical outcomes in three groups were recorded prospectively over time. A total of 159 (23.1%) patients underwent precut fistulotomy. The mean procedure time was decreased as the number of procedures increased (p < 0.01). The success rates of selective biliary cannulation in the three groups were 86.8, 86.8, and 88.7% respectively, for the first attempt (p = 0.77) and 93.7% for the second attempt. Post-ERCP pancreatitis developed in nine (5.7%) patients, which was not statistically significant between the three groups. As the frequency of papillary contacts increased, post-ERCP pancreatitis tended to increase (p = 0.017). In the multivariate analysis, more tha...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.

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.
