• 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 is the Best way to Manage Diverticulitis, and how Many People Have it?

Not all patients with multiple episodes of diverticulitis should undergo preventative surgery, shows a Markov decision model published in the January 2016 issue of Clinical Gastroenterology and Hepatology. Elective surgery after 2 episodes produces fewer quality-adjusted life-years (QALYs) than surgery after 3 episodes or conservative or medical treatments, the model found.

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

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

VIDEO: Endoscopic Management of Gastrointestinal Leaks and Fistulae

Gastrointestinal leaks and fistulae can be serious acute complications or chronic conditions caused by inflammation, malignancy, or surgery. In a Perspective article in the October issue of Clinical Gastroenterology and Hepatology, Field F. Willingham and Jonathan M. Buscaglia discuss advanced endoscopic methods for less invasive treatment of these luminal defects. They explain that the main goal of

VIDEO: Endoscopic Suturing for Ulcer Exclusion

Researchers report the use of endoscopic surgical suturing for ulcer exclusion in the July issue of Gastroenterology, and provide a video of their procedure. It is important to prevent rebleeding of peptic ulcers. A prototype endoscopic suturing device has been developed to provide hemostasis in patients with massively bleeding gastric ulcers. Philip Wai Yan Chiu et

Is Stretta an Effective Treatment for GERD?

An expensive radiofrequency ablation technique known as Stretta does not benefit patients with gastroesophageal reflux disease (GERD), researchers report in the June issue of Clinical Gastroenterology and Hepatology. In a meta-analysis of randomized controlled studies, Seth Lipka et al found no evidence that Stretta normalized esophageal pH values, augmented lower esophageal

What are the Effects of Antiviral Therapy in Patients With IBD and CMV Infection?

Cytomegalovirus (CMV) infection complicates inflammatory bowel disease (IBD), but anti-viral therapy reduces the need for bowel surgery, researchers report in the May issue of Clinical Gastroenterology and Hepatology. The benefits of anti-viral treatment are greatest for patients with high-grade disease, they show. CMV infection is more common in patients with

Is Fecal Calprotectin a Good Marker of Crohn’s Disease Recurrence?

The fecal concentration of calprotectin can be used to monitor for recurrence of Crohn’s disease, with a high enough negative predictive value that physicians can be confident they won’t miss patients with recurrent disease, researchers report in the May issue of Gastroenterology. Approximately 80% of patients with Crohn’s disease require surgery
