Video: EUS Detection of Early-stage Gastric Cancer in a Patient with FAP

Endoscopic ultrasound (EUS) can detect early-stage gastric cancers developing beneath or within the mucosa that are not visualized by endoscopy in patients with familial adenomatous polyposis (FAP). Researchers report these findings along with a video in the August issue of Gastroenterology. FAP is a hereditary colorectal cancer syndrome characterized by colorectal polyps and colorectal cancer. Patients

  • Can THC Relieve Chronic Abdominal Pain?

Can THC Relieve Chronic Abdominal Pain?

In a phase 2 study, researchers found no difference between a delta-9-tetrahydrocannabinol (THC) tablet and a placebo tablet in reducing pain measures in patients with chronic abdominal pain from pancreatitis or surgery. Authors Marjan de Vries and Harry van Goor explain their findings in their video abstract: The study was

  • FISH and Mutations Best Identify Biliary Stricture Malignancies

FISH and Mutations Best Identify Biliary Stricture Malignancies

Addition of fluorescence in situ hybridization (FISH) and mutation analyses to cytology analysis significantly increases the sensitivity of detection of malignancies in biliary strictures, researchers report in the June issue of Clinical Gastroenterology and Hepatology. These techniques can be performed using standard brush samples collected during endoscopic retrograde cholangiopancreatography, with mutations detected in

  • Bioinformatic Search Identifies Tapeworm Drug for Treatment of Hepatocellular Carcinoma

Bioinformatic Search Identifies Tapeworm Drug for Treatment of Hepatocellular Carcinoma

In a bioinformatic search for agents that alter the hepatocellular carcinoma (HCC)-specific gene expression pattern, researchers identified the anthelmintic drug niclosamide as a potential anti-tumor agent, described in the June issue of Gastroenterology. Niclosamide and its ethanolamine salt (NEN), with greater bioavailability, slowed growth of genetically induced liver tumors and

FUSE Outperforms Forward-viewing Colonoscopy in Detecting Dysplasia in Patients With IBD

The panoramic views obtained with full-spectrum endoscopy (FUSE) increase the number of dysplastic lesions detected in the colon, compared with conventional forward-viewing colonoscopy, researchers report in the May issue of Gastroenterology. Inflammatory bowel diseases (IBDs) increase the risk of colorectal cancer. Surveillance colonoscopy with chromoendoscopy is recommended, but conventional forward-viewing colonoscopy

Gastroduodenal Metastases from Melanoma

Researchers describe a case of gastroduodenal metastases from cutaneous melanoma, in the May issue of Gastroenterology. Inês Pita et al present the case of a 76-year-old man who arrived at the emergency department with exertional dyspnea and melena for the past 3 weeks, and an episode of presyncope. He denied orthopnea, paroxysmal nocturnal dyspnea,

  • Hemosuccus Pancreaticus Caused by a Pancreatic Tumor

Hemosuccus Pancreaticus Caused by a Pancreatic Tumor

Researchers describe a rare cause of hemosuccus pancreaticus in a patient with pancreatic cancer. The gastrointestinal bleeding was caused by erosion of pancreatic adenocarcinoma into the colon, they show in the April issue of Clinical Gastroenterology and Hepatology. Hemosuccus pancreaticus is defined as hemorrhage from the ampulla of Vater via the pancreatic

  • What are the Different Types of Liver Cancer, and How do They Develop?

What are the Different Types of Liver Cancer, and How do They Develop?

A review article in the March issue of Gastroenterology discusses different hypotheses about the cells responsible for liver tumorigenesis. The article also reviews the different classes of liver tumors, based on the molecular features, and how these affect patient prognosis. Daniela Sia et al describe the distinct molecular and clinical features of hepatocellular

Video: Screening Breath Compounds to Identify Patients With Barrett’s Esophagus

Researchers can identify patients with Barrett’s esophagus (BE) based on profiles of exhaled volatile organic compounds measured with an electronic nose device. This tool, described in the January issue of Gastroenterology, provides a portable, accessible, and widely acceptable tool for screening and surveillance for BE in patients with gastroesophageal reflux

  • How Can We Study Genetic Heterogeneity Within Hepatocellular Carcinomas?

How Can We Study Genetic Heterogeneity Within Hepatocellular Carcinomas?

Researchers have developed a patient-derived cell line-based model to study how intratumor heterogeneity affects sensitivity of hepatocellular carcinoma (HCC) to different therapeutic agents, reported in the January issue of Gastroenterology. HCCs have a large amount of genetic heterogeneity within each tumor, making them difficult to treat. Multiple regions of tumors
