Splenic Size and Portal Vein Diameter on Ultrasound in Predicting Esophageal Variceal Bleeding Risk
Обзор
This prospective observational study aims to evaluate the accuracy of using routine abdominal ultrasound to predict the risk of esophageal variceal bleeding in adult patients with liver cirrhosis. Esophageal variceal bleeding is a serious complication of chronic liver disease. While upper gastrointestinal endoscopy is the current standard for diagnosing and grading these varices, it is an invasive procedure. In this study, researchers will use ultrasound to measure the patient's spleen size and portal vein diameter. These non-invasive measurements will then be compared to the results of a standard upper endoscopy performed within 48 to 72 hours. The goal is to determine if these simple ultrasound measurements can reliably predict the presence, grade, and bleeding risk of esophageal varices, which could potentially reduce the need for routine invasive endoscopic screenings in the future.
Подробное описание
Background and Rationale:
Esophageal variceal bleeding is a life-threatening complication of portal hypertension in patients with chronic liver disease. While upper gastrointestinal endoscopy remains the gold standard for diagnosing and grading esophageal varices, it is an invasive procedure. Recent studies demonstrate that non-invasive parameters, specifically ultrasonographic measurements like portal vein diameter and splenic size, have emerged as independent predictors of variceal presence and bleeding risk. Despite these findings, there is limited data from Egyptian populations, particularly from Upper Egypt. This study aims to assess the diagnostic accuracy of these measurements and establish optimal cutoff values for non-invasive parameters in this population.
Study Design and Setting:
This is a prospective cross-sectional observational study conducted at the Department of Tropical Medicine and Gastroenterology and the Department of Diagnostic Radiology at AL-Rajhi University Hospital, Assiut University, Egypt. The study aims to recruit 165 adult patients with liver cirrhosis.
Study Procedures:
All enrolled participants will undergo the following assessments:
Clinical and Laboratory Assessment: Participants will undergo comprehensive history taking and physical examinations, alongside the calculation of Child-Pugh and Model for End-Stage Liver Disease (MELD) scores. Blood samples will be evaluated for complete blood count (focusing on platelets), liver and renal function tests, and prothrombin time/INR.
Abdominal Ultrasound: A high-resolution ultrasound using a 3.5-5 MHz convex transducer will be performed to measure the longest craniocaudal splenic diameter, splenic width and thickness, and portal vein diameter at the porta hepatis. Additional assessments include splenic vein diameter, ascites, liver echotexture, and the calculation of the platelet count/spleen diameter ratio.
Upper Gastrointestinal Endoscopy: Within 48-72 hours of the ultrasound, an endoscopy will be performed. Investigators will grade the varices (Grade I-III), assess for red color signs (indicating high bleeding risk), and document any gastric varices or portal hypertensive gastropathy.
