What is This Liver Tumor?

Researchers describe a rare liver tumor of vascular origin in the May issue of Clinical Gastroenterology and Hepatology. Laisa Socorro Briongos-Figuero and Tomás Zamora-Martínez describe the case of a 59-year-old man with chronic pancreatitis who was was admitted to the hospital with vomiting and jaundice, without fever or diarrhea. He had a previous history of

Liver Metastases, or Syphilis?

Researchers report initially mistaking late-stage syphilis for liver metastases in the November issue of Clinical Gastroenterology and Hepatology. Irphan Gaslightwala et al describe a 59-year-old man with a history of chronic lymphocytic leukemia; 6 months of persistent fevers, chills, and night sweats; and loss of 50 pounds. A positron emission tomography–computed tomography

  • Using High-resolution Microendoscopy to Detect Gastrointestinal Neoplasia

Using High-resolution Microendoscopy to Detect Gastrointestinal Neoplasia

The high-resolution microendoscope (HRME) allows for real-time imaging of the esophageal and gastric epithelium with subcellular resolution. In an Advances in Translational Science article in the November issue of Clinical Gastroenterology and Hepatology, Justin S. Louie et al discuss the performance of this portable, low cost, optical biopsy technology in screening and surveillance of gastrointestinal

Bone Tumors, Abdominal Pain, and Aspirin

Physicians report an unusual case of a man with abdominal pain that responded to aspirin therapy, in the October issue of Gastroenterology. It turns out that the pain was caused by a prostaglandin-producing benign bone tumor. Harpal S. Dhaliwal et al. describe examination of a 33-year-old man with an 18-month history

Video: Which Patients with Crohn’s Disease Need a CT Scan?

Researchers have developed a system to identify patients with Crohn’s disease who do not require computed tomography (CT) evaluation, described by Shail M. Govani et al  in the October issue of Clinical Gastroenterology and Hepatology. The system uses laboratory test results to avoid CT analysis, and thereby unnecessary exposure to radiation and increased cancer risk. People who come to the emergency department with

Can we Increase Detection of Duct Abnormalities by MRCP?

Administration of secretin improves noninvasive imaging of pancreatic duct abnormalities with higher levels of sensitivity than magnetic resonance cholangiopancreatography (MRCP), researchers report in the September issue of Gastroenterology. Pancreatic imaging is an essential element in evaluation of patients with abdominal pain or suspected pancreatitis. MRCP allows physicians to visualize fluid

Real-Time Views of Gastrointestinal Motility

Bioengineers have found a way to visualize the action of the gastrointestinal tract in real-time, developing a non-invasive means to observe the wave-like muscle contractions that occur during peristalsis. According to the NIH Director’s blog, new technologies are needed to aid in diagnosis and treatment of the wide range of

  • Cancer Cells in Circulation

Cancer Cells in Circulation

Pancreatic cancer cells can be detected in patients’ circulation before tumors are discovered, researchers report in the March issue of Gastroenterology. Cancer cells have long been believed to acquire metastatic potential after large primary tumors are established. However, many patients undergoing pancreatectomy for chronic pancreatitis are found to have disseminated pancreatic

What is the Best Way to Assess Bile Duct Strictures?

Researchers describe new methods to collect and process bile duct biopsies for evaluation of strictures, in the September issue of Clinical Gastroenterology and Hepatology. These approaches should provide a greater quantity of material for analysis and increase the accuracy of diagnosis. A biliary stricture is an abnormal narrowing of the

Tracking Pancreatic Cancer Cells

Tumors spread to other parts of the body when cancer cells can escape into the bloodstream, although it is not exactly clear how they enter the circulation or decide where to form new tumors. Andrew Rhim and colleagues at the University of Pennsylvania have developed a technology to label tumor
