• Are Eating Competitions Dangerous?

Are Eating Competitions Dangerous?

The stomachs of competitive eaters accommodate large quantities of food by repeated rapid distension of the gastric wall during eating episodes. A Clinical Challenges and Images in GI article in the June issue of Gastroenterology presents an adverse outcome of these competitions. Tian-Zhi Lim et al describe the case of a 30-year-old, healthy man

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

  • Why do Pancreatic Tumor Cells Love the Liver?

Why do Pancreatic Tumor Cells Love the Liver?

Pancreatic ductal adenocarcinoma (PDAC) and its precursors secrete high levels of tissue inhibitor of metalloproteinases 1 (TIMP1) into the circulation, which activates hepatic stellate cells (HSCs) in liver. These cells help create a niche that promotes metastasis of pancreatic tumors to liver, researchers report in the November issue of Gastroenterology.

  • Does Pancreatectomy With Islet Autotransplantation Benefit Patients With Recurrent Acute Pancreatitis?

Does Pancreatectomy With Islet Autotransplantation Benefit Patients With Recurrent Acute Pancreatitis?

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

  • 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

  • What can we do with Gastrointestinal Organoids?

What can we do with Gastrointestinal Organoids?

Researchers review the latest discoveries from studies of tissue-derived and pluripotent stem cell–derived intestinal, gastric, esophageal, liver, and pancreatic organoids in the May issue of Gastroenterology. Studies of organoids have provided valuable information about GI development, tissue homeostasis, and disease and might be used to develop personalized medicines. In vitro organoid cultures are

  • 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

  • Distinguishing a Pancreatic Pseudocyst from a Mucinous Cystic Neoplasm

Distinguishing a Pancreatic Pseudocyst from a Mucinous Cystic Neoplasm

Researchers describe the case of a patient with what appeared to be a pancreatic pseudocyst that was found to be a benign mucinous cystic neoplasm (MCN), based on analysis of a cyst wall biopsy. In the March issue of Gastroenterology, Katie Connor et al  describe a 22-year-old woman who came

Pancreaticobiliary Maljunction and Neuroendocrine Carcinoma

Researchers describe an unusual case—a patient with a neuroendocrine carcinoma of the gallbladder accompanied by pancreaticobiliary maljunction—in the March issue of Clinical Gastroenterology and Hepatology. Tomonori Matsumoto et al examined a 58-year-old man with epigastric pain. Computed tomography (A) and fluoro-2-deoxy-d-glucose positron emission tomography (B) revealed angular diffuse thickening of the gallbladder

  • 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
