  • A Mouse Model for Studying Pancreatic Tumor Resection and Adjuvant Therapy

A Mouse Model for Studying Pancreatic Tumor Resection and Adjuvant Therapy

Researchers have developed mice that develop focal, resectable pancreatic tumors closely resembling human pancreatic ductal adenocarcinomas (PDACs) that can be used to test adjuvant therapies, according to new research in the August issue of Gastroenterology. The authors show that administration of gemcitabine after resection of the tumors activates natural killer (NK) cell-mediated

  • Why Isn’t Radiation Therapy Effective for Pancreatic Tumors?

Why Isn’t Radiation Therapy Effective for Pancreatic Tumors?

In pancreatic tumors of mice, radiation causes infiltration by macrophages that acquire an immune-suppressive phenotype that disables T-cell–mediated anti-tumor responses, researchers report in the June issue of Gastroenterology. Blocking colony stimulating factor (CSF1 or MCSF) prevents this process, allowing radiation to slow tumor growth, they show. Most patients with pancreatic

  • Do NSAIDs Prevent PEP?

Do NSAIDs Prevent PEP?

Rectal indomethacin does not prevent pancreatitis following endoscopic retrograde cholangiopancreatography (ERCP), researchers report from a randomized controlled study published in the April issue of Gastroenterology. These findings contradict more than a decade of evidence that nonsteroidal anti-inflammatory drugs (NSAIDs) decrease the risk of post-ERCP pancreatitis (PEP). Acute pancreatitis is the

What is Causing the Increased Detection of Pancreatic Cysts?

Advances in imaging technologies over the past decades have greatly increased the numbers of pancreatic cysts detected, researchers report in the April issue of Clinical Gastroenterology and Hepatology. With further improvements in pancreatic imaging, more pancreatic cysts are likely to be discovered, so gastroenterologists, surgeons, endoscopic ultrasound specialists, and primary

  • Do Proton Pump Inhibitors Reduce the Need for Phlebotomy in Patients With Hereditary Hemochromatosis?

Do Proton Pump Inhibitors Reduce the Need for Phlebotomy in Patients With Hereditary Hemochromatosis?

In certain patients with hereditary hemochromatosis (HH), treatment with proton pump inhibitors (PPIs) for 2 or more years significantly reduced the number of phlebotomies required to maintain serum levels below 100 μg/L, researchers report in the January issue of Clinical Gastroenterology and Hepatology. HH is one of the most common

  • Finding Circulating Tumor Cells in Patients With Pancreaticobiliary Cancers

Finding Circulating Tumor Cells in Patients With Pancreaticobiliary Cancers

Circulating tumor cells (CTCs) can be isolated from portal venous blood collected during endoscopic ultrasound (EUS) of patients with pancreaticobiliary cancers, researchers report in the December issue of Gastroenterology. CTCs isolated from peripheral blood of patients with metastatic breast, colorectal, or prostate cancer can be analyzed to predict patient survival. However, blood samples from

  • Can We Use a Yeast Lipase in Enzyme Replacement Therapy for Pancreatic Exocrine Insufficiency?

Can We Use a Yeast Lipase in Enzyme Replacement Therapy for Pancreatic Exocrine Insufficiency?

An orally administered yeast lipase increases digestion of fat in a minipig model of pancreatic exocrine insufficiency (PEI), similar to that of pancreatin used in pancreatic enzyme replacement therapy, researchers report in the December issue of Gastroenterology. Patients with PEI have decreased pancreatic secretion of digestive enzymes such as lipase. This

  • Who Should Undergo Surgery for Pancreatic Cysts?

Who Should Undergo Surgery for Pancreatic Cysts?

When should a patient with a pancreatic cystic lesion undergo surgery? How can we tell if the surgery will provide relief, or prevent death from pancreatic cancer, or burden a patient with an unnecessary procedure? Two articles in the October issue of Clinical Gastroenterology and Hepatology increase our understanding of

Special Issue: Genetics, Genetic Testing, and Biomarkers of Digestive Diseases

A special issue of Gastroenterology features 14 articles discussing the genetic factors that contribute to a range of gastrointestinal (GI),  hepatobiliary, and pancreatic diseases, and how this information can be used in diagnosis and treatment of patients. An introduction to the special issue explains the value of associating diseases with specific genetic variants, which can help

Should Patients Undergo Endoscopic Sphincterotomy Before Receiving Self-expandable Metallic Stents?

Endoscopic sphincterotomy (ES) provides no benefit to patients receiving self-expandable metallic stents (SEMS) for a biliary stricture caused by pancreatic cancer, researchers report in the June issue of Clinical Gastroenterology and Hepatology. The randomized controlled trial showed that ES procedure did not affect number of adverse events, SEMS patency, or
