  • Quality of Capsule Endoscopy Reporting in Patients Referred for Double Balloon Enteroscopy

    Abnormal video capsule endoscopy (VCE) findings often require intervention with double balloon enteroscopy (DBE). Accurate VCE reporting is important for procedural planning. In 2017 the American Gastroenterological Association (AGA) published a guideline that included recommended elements for VCE reporting.

  • Endoscopic Ultrasound Predicts Risk of Occult Intra-Abdominal Metastases in Localized Gastric Cancer: A Validation Study

    In gastric cancer (GC) patients without imaging evidence of distant metastasis, diagnostic staging laparoscopy (DSL) is recommended to detect radiographically occult peritoneal metastasis (M1). DSL carries a risk for morbidity and its cost-effectiveness is unclear.

  • Clinical Features and Management of Small Bowel Masses Detected During Device-Assisted Enteroscopy: A Multi-Center Experience

    Small bowel mass lesions (SBMLs) are rare, span a range of different histologies and phenotypes, and our understanding of them is limited. Some lesions occur in patients with recognized polyposis syndromes and others arise sporadically.

  • Development of a Predictive Model for Common Bile Duct Stones in Patients With Clinical Suspicion of Choledocholithiasis: A Cohort Study

    Current choledocholithiasis guidelines heavily focus on patients with low or no risk, they may be inappropriate for populations with high rates of choledocholithiasis. We aimed to develop a predictive scoring model for choledocholithiasis in patients with relevant clinical manifestations.

  • Proton Pump Inhibitors Use and Increased Risk of Spontaneous Bacterial Peritonitis in Cirrhotic Patients: A Retrospective Cohort Analysis

    Since their introduction in the early 1980s, proton pump inhibitors (PPIs) have been used worldwide for a broad range of indications. Unfortunately, however, PPIs have become overly prescribed by healthcare providers, sometimes in the absence of clear indications.




Video Capsule Endoscopy in Gastroenterology
Video capsule endoscopy (VCE) is a wireless technology used by gastroenterologists for various indications in their clinical practice. There has been significant improvement in this technology since its start about two decades ago. Specific video capsules have been made to evaluate the small bowel, colon, and esophagus.

Cytomegalovirus Infection Is Associated With Adverse Outcomes Among Hospitalized Pediatric Patients With Inflammatory Bowel Disease
Adults with inflammatory bowel disease (IBD) are at increased risk of developing cytomegalovirus (CMV) colitis, which is associated with adverse outcomes. Similar studies in pediatric IBD patients are lacking. Full Text

Key Clinical Image

Esophageal Ulcer After Intravitreal Ranibizumab Injection in a Patient With Age-Related Macular Degeneration
anibizumab is a monoclonal antibody fragment targeted against vascular endothelial growth factor (VEGF) A isoform (VEGF-A). This study aimed to report a case of esophageal ulcer that developed soon after intravitreal ranibizumab injection in a patient with age-related macular degeneration (AMD). Full Text
