A Quantitative Ultrasound Technology to Identify Patients with NAFLD and Quantify Steatohepatitis

A new quantitative ultrasound (QUS)  can accurately identify patients with non-alcoholic fatty liver disease (NAFLD) and quantify hepatic steatosis, researchers report in the July issue of Clinical Gastroenterology and Hepatology. With further validation, QUS could be an inexpensive, widely used technique to screen the general or at-risk population for NAFLD. The estimated prevalence of NAFLD

Can Capsule Colonoscopy Accurately Detect Polyps and Adenomas?

In an average-risk screening population, capsule colonoscopy identified individuals with polyps and adenomas with high levels of specificity, researchers report in the May issue of Gastroenterology. This procedure might be useful for patients who cannot undergo colonoscopy or who had incomplete colonoscopies. Capsule endoscopy, which involves an ingestible pill-sized endoscope that

What to do About Sessile Serrated Adenomas

Sessile serrated adenomas (SSAs), characterized by the saw-toothed appearance of the colonic crypts, form and progress to colorectal cancers (CRCs) via a different pathway than conventional adenomas and are thought to contribute to 20% to 35% of all cases of CRC. Although little is known about their pathogenesis, endoscopists must be aware of the unique features of SSAs to efficiently detect

Cancer Cells in Circulation

Pancreatic cancer cells can be detected in patients’ circulation before tumors are discovered, researchers report in the March issue of Gastroenterology. Cancer cells have long been believed to acquire metastatic potential after large primary tumors are established. However, many patients undergoing pancreatectomy for chronic pancreatitis are found to have disseminated pancreatic

Can We Increase Survival of Patients with Gastric Cancer?

Researchers have identified factors that affect life expectancy of patients with stomach cancer, reported in the December issue of Clinical Gastroenterology and Hepatology. Use of these factors to increase early detection of gastric adenocarcinoma could greatly increase survival times among patients. Gastric cancer is a significant cause of mortality and

What to do About Gastric Polyps

When clinicians detect a gastric polyp during endoscopy, they are faced with many questions: does the polyp need to be excised, or can a biopsy sample be collected and analyzed? Which polyps should be biopsied? Should patients then be followed, and how? In the November issue of Clinical Gastroenterology and

Why Do People Still Develop Colorectal Cancer After Colonoscopy?

Some people who receive screening colonoscopies are still at risk for colorectal cancer (CRC) because neoplastic polyps found are not completely removed, according to the January issue of Gastroenterology. While the quality of colonoscopy examinations has focused on polyp detection, better methods are needed to evaluate polyp removal. The goal
