  • Pre- and Post-Implant Endoscopy in Left Ventricular Assist Device Recipients: A Single-Center Experience

    Gastrointestinal bleeding (GIB) is common in left ventricular assist devices (LVADs) patients, but the optimal screening approach before LVAD implantation is still unclear. The aim of the study was to describe our experience with pre- and post-LVAD implantation endoscopic screening and subsequent GI bleeding in this cohort.

  • Timing and Outcomes of Percutaneous Endoscopic Gastrostomy After Ischemic Stroke

    Guidelines recommend using percutaneous endoscopic gastrostomy (PEG) for dysphagia after 2 weeks of stroke onset. We aimed to study the impact of PEG timing on outcomes in patients with ischemic stroke.

  • Takotsubo Cardiomyopathy Associated With Acute Pancreatitis

    akotsubo cardiomyopathy is classically associated with emotional stress in middle-aged women. In clinical practice, physical stressors are a more common cause of Takotsubo cardiomyopathy.

  • 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.
