High Progression Risk in Low-Grade Dysplasia Barrett's
MedScape Multispeciality online
This was "a great presentation on a very confusing topic," said Nicholas Shaheen, MD, from the University of North Carolina at Chapel Hill.
He noted, however, there is substantial variability in reported rates of progression from low-grade dysplasia to esophageal adenocarcinoma. In a Dutch study, for example, rates were as high as 13.4% (Am J Gastroenterol. 2010;105:1523-1530).
Dr Shaheen asked Dr Krishnamoorthi if he could explain why the annual incidence rate in this study is so much lower...
Are PPIs Enough? Controlling Acid After Ablation of Barrett’s Esophagus
General Surgery News online
“If the endoscopy shows erosive disease or the biopsies show lots of inflammation, we intensify therapy,” explained Nicholas Shaheen, MD, chief of the Division of Gastroenterology & Hepatology at the University of North Carolina School of Medicine, in Chapel Hill. Although intensifying therapy means improving acid control, Dr. Shaheen reported, “I do not routinely monitor pH.”...
Case Volume Tied To Recurrence Rates After RFA for Barrett’s
Gastroenterology & Endoscopy News online
After three years of follow-up, the recurrence rate at low-volume centers was about 20% greater than that for high-volume centers, according to the researchers, from the University of North Carolina (UNC) at Chapel Hill. Nicholas Shaheen, MD, chief of the Division of Gastroenterology and Hepatology at UNC, said the differences were both clinically and statistically significant.
Cary Cotton, a medical student working under Dr. Shaheen, presented the findings at the 2014 annual meeting of the American College of Gastroenterology (abstract 38)...
Endoscopy Overused in Heartburn Patients
Doctors use endoscopy in GERD patients mainly to check for a condition called Barrett's esophagus, which affects about 10% of people who’ve had chronic heartburn for at least five years, says Nicholas Shaheen, MD, MPH, an author of the new advice paper. Barrett’s occurs when stomach acids damage the lining of the esophagus...
UNC Researchers Test New Treatment for Acid Reflux
Paul Bailey, 60, complained of heartburn and acid reflux for more than 15 years. UNC gastroenterologist Dr. Nicholas Shaheen included him in a study to test a new out-patient treatment for Barrett's Esophagus.
The Halo 360 is an endoscopic treatment developed by Barrx Medical. It uses precisely controlled heat that burns the surface layer of tissue.
"The idea here is that we're burning up that tissue in the hopes that regular tissue is going to repopulate this area," Shaheen said while pointing to a photograph of the burned treatment area of Bailey's esophagus...

BACKGROUND & AIMS: The published risk of adenocarcinoma in the setting of Barrett's esophagus (BE) varies. Publication bias, the selective reporting of studies featuring positive or extreme results, may result in overestimation of this cancer risk in the literature. The aim ...
