What Endoscopic Techniques are Available for Weight Loss?

Endoscopic techniques have been approved by the FDA for management of obesity, with many new devices and technologies in development. The pros and cons of these approaches, and the questions to be answered, are covered in a review article by Andrew C. Storm et al in the November issue of Clinical

  • Effects of Diet, Intestinal Inflammation, and the Microbiome on Risk of Colorectal Cancer

Effects of Diet, Intestinal Inflammation, and the Microbiome on Risk of Colorectal Cancer

Diets that promote intestinal inflammation can increase risk of colorectal carcinomas associated with specific bacteria in the microbiome, researchers report in the October issue of Clinical Gastroenterology and Hepatology. Diet-induced intestinal inflammation alters the gut microbiome to contribute to colorectal cancer risk, which might be reduced with dietary changes. Chronic inflammation

  • Dyspepsia and Hyperamylasemia Due to Plastic Spork Ingestion

Dyspepsia and Hyperamylasemia Due to Plastic Spork Ingestion

Researchers report a case of abdominal pain and hyperamylasemia due a duodenal foreign body in the September issue of Clinical Gastroenterology and Hepatology. Lotje Korteweg et al describe the case of a 38-year old man referred for endoscopic retrograde cholangiopancreatography. A gastroduodenoscopy had been performed for chronic dyspepsia and showed

Gastroenterology Special Issue on Endoscopy

A special issue of Gastroenterology, Advances in Endoscopic Therapy, presents the latest advances in gastrointestinal endoscopy, including endoscopic images and videos. In their introductory article, Jacques J. Bergman and Patrick S. Yachimski explain that endoscopy is central to gastroenterology clinical practice and research, allowing examination of healthy and diseased tissue from the organ level, to the

  • Model: Microfabricated Crypt Scaffolds for Studying Human Colon Stem Cells

Model: Microfabricated Crypt Scaffolds for Studying Human Colon Stem Cells

Researchers created an in vitro human colon crypt array that provides an accurate representation of human intestinal crypts, reported in the February issue of Cellular and Molecular Gastroenterology and Hepatology. This system re-creates an intestinal epithelium with a high density of polarized crypts that respond in a physiologic manner to growth factors, metabolites, or

  • What Happens in the Intestine in Patients With Wilson Disease?

What Happens in the Intestine in Patients With Wilson Disease?

ATP7B regulates vesicular storage of copper and buffers its levels in enterocytes to maintain a range necessary for formation of lipid-transporting vesicles, researchers report in the January issue of Gastroenterology. The authors show that a misbalance of copper and lipid in the intestine could account for gastrointestinal manifestations of Wilson

  • Hookworms Cause GI Bleeding

Hookworms Cause GI Bleeding

Hookworms, although uncommon, are an important cause of gastrointestinal bleeding in patients of all ages, researchers remind readers in the November issue of Clinical Gastroenterology and Hepatology. Puneet Chhabra and Deepak K. Bhasin describe the case of a 72-year-old man with Parkinson disease who presented with fatigue, dyspnea on exertion, and

  • 3-D Imaging of T-cell Localization in Inflamed Colon Tissues

3-D Imaging of T-cell Localization in Inflamed Colon Tissues

Light sheet fluorescence microscopy (LSFM) provides accurate 3-dimensional images of inflammed intestine of mice with colitis, researchers show in a Gastroenterology in Motion article and video in the October issue of Gastroenterology. The authors demonstrate use of the technology to analyze migration of human T cells in colons of mice with colitis. Improved techniques are

  • Could the Microbiota Link Metabolic Syndrome With Inflammation?

Could the Microbiota Link Metabolic Syndrome With Inflammation?

Bacterial encroachment—shrinking of the bug-free zone adjacent to the colonic epithelium—is a feature of metabolic syndrome, researchers report in the September issue of Cellular and Molecular Gastroenterology and Hepatology. The findings could explain the relationship between diabetes and inflammation. Mucoid structures that coat the epithelium keep the intestinal microbiota at

  • The Case of the Missing Acupuncture Needle – Solved by 3-D CT

The Case of the Missing Acupuncture Needle – Solved by 3-D CT

Researchers describe the loss and internal migration of an acupuncture needle, and its recovery using 3-dimensional reconstruction computed tomography (CT), in the July issue of Gastroenterology. An-qi He et al, report the case of a 62-year-old woman in China who presented with abdominal pain in the left lower quadrant. Her “needle-like abdominal
