Yield of repeat forward-view examination of the right side of the colon in screening and surveillance colonoscopy

Gastrointestinal Endoscopy

Abstract

Colonoscopy is less protective for cancers of the right side of the colon than for distal colon cancers. Repeat examination of the right side of the colon has been suggested to increase adenoma detection and potentially provide greater protection against the development of cancers of the right side of the colon. Our prospective study assessed the yield of a second forward-view examination of the right side of the colon done immediately after the initial examination. All men 50 to 75 years of age undergoing screening or surveillance colonoscopy at the West Haven Veterans Affairs Medical Center were invited to participate. A second forward-view examination was performed if the Boston Bowel Preparation Scale score was 8 to 9 (scale = 0-9) with right a side of the colon segment score of 2 to 3 (scale = 0-3). The primary outcome was the per-patient adenoma detection rate (including sessile serrated polyps) on a repeated examination of the right side of the colon, defined as the number of patients with ≥1 adenoma on the second examination of the right side of the colon divided by total number of patients. An increase in the adenoma detection rate (ADR) was a secondary outcome. Repeated examination of the right side of the colon, perf...Continue Reading

COVID-19

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.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

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.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

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.

Microbicide

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.
