  • 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.

  • Acute Upper Gastrointestinal Bleeding: Less Severe Bleeding in More Frail and Older Patients, Comparison Between Two Time Periods Fifteen Years Apart

    Acute upper gastrointestinal bleeding (AUGIB) remains a common medical emergency with considerable morbidity and mortality. The aim of this study was to describe the patient characteristics, diagnoses and clinical outcomes of patients presenting with AUGIB nowadays and compare these with those of patients 15 years ago.

  • The Incidence of Venous Thromboembolism and Practice of Deep Venous Thrombosis Prophylaxis Among Hospitalized Cirrhotic Patients

    Patients with liver cirrhosis have altered hepatic synthetic functions which theoretically result in reduced levels of pro-and anti-coagulant factors as well as thrombocytopenia. Initially, cirrhotic patients were thought to be at an increased risk of bleeding and a reduced risk of thrombosis.

Barriers to Hepatitis C Virus Care and How Federally Qualified Health Centers Can Improve Patient Access to Treatment

Key Clinical Image

Flood Syndrome
Flood syndrome refers to the exsanguination of ascitic fluid following the spontaneous rupture of an umbilical hernia, and is a rare complication of liver cirrhosis with ascites. In this case report, we describe a 67-year-old patient with Flood syndrome who was initially managed conservatively in a community hospital run by primary care physicians, prior to transfer to a tertiary hospital for specialist surgical review and management.
