Magnetic resonance elastography (MRE) is more accurate than transient elastography (TE) in identifying liver fibrosis of stage 1 or more, researchers report in the February issue of Gastroenterology, using biopsy analysis as the standard. They also show that MRI-based proton density fat fraction (MRI-PDFF) analysis is more accurate than TE-based
Read moreEndoscopy during pregnancy is associated with slight increases in risk of preterm birth and small for gestational age, but not congenital malformation or stillbirth, researchers report in a nationwide population-based cohort study published in the February issue of Gastroenterology. However, the authors believe the small increase in risk to be

Researchers can identify patients with Barrett’s esophagus (BE) based on profiles of exhaled volatile organic compounds measured with an electronic nose device. This tool, described in the January issue of Gastroenterology, provides a portable, accessible, and widely acceptable tool for screening and surveillance for BE in patients with gastroesophageal reflux

Endoscopic sleeve gastroplasty (ESG) delays gastric emptying, induces early satiation, and significantly reduces body weight, researchers report in the January issue of Clinical Gastroenterology and Hepatology. ESG could therefore be an alternative to bariatric surgery for some patients with obesity. Although bariatric surgery is the most effective therapy for obesity,

Researchers have developed a mobile health index for remote monitoring of patients with inflammatory bowel diseases (IBD) that could be incorporated into a smartphone app. These findings are reported in the December issue of Clinical Gastroenterology and Hepatology. The shift from symptom-oriented to prevention-oriented care delivery has accelerated the development of

In patients with recurrent acute pancreatitis, total pancreatectomy with islet autotransplantation (TPIAT) reduces pain and requirements for narcotic therapy, and increases quality of life, researchers report in the September issue of Clinical Gastroenterology and Hepatology. This treatment should be considered when medical and endoscopic therapies have failed. Recurrent acute pancreatitis, caused

Dysbiosis contributes to the pathogenesis of inflammatory bowel diseases (IBD) by altering colonic expression of genes that regulate inflammation and the immune response, researchers report in the July issue of Cellular and Molecular Gastroenterology and Hepatology. An altered intestinal microbiota composition has been associated with IBD. However, it is not

People have high plasma levels of interleukin-6 (IL6) and c-reactive protein years before they are diagnosed with inflammatory bowel diseases (IBD), researchers report in the June issue of Clinical Gastroenterology and Hepatology. These markers of systemic inflammation could be features of early-stage disease used to identify patients at risk. Crohn’s

Undifferentiated or crypt-like, and differentiated or villus-like, human intestinal enteroids represent distinct points along the crypt–villus axis and can be used to characterize electrolyte transport processes along the small intestine, researchers report in the March issue of Gastroenterology. Studies of their duodenal enteroid model showed that electrogenic Na+/HCO3– cotransporter 1 in the

The intestine adapts differently to Roux-en-Y gastric bypass (RYGB) than to vertical sleeve gastrectomy (VSG), researchers show in the February issue of Gastroenterology. RYGB increases intestinal glucose disposal whereas VSG delays glucose absorption, but each reduces glycemia. Bariatric surgeries such as RYGB and VSG are the most effective ways to resolve
