Abdomen Sonography: Gastrointestinal System Pathology - Video Lesson

Hey, everyone. Welcome back to our lessons in abdominal ultrasound. In today's lesson, we're going to explore the gastrointestinal system and its many potential abnormalities. We'll review how to assess the bowel sonographically, identify signs of obstruction and inflammation, and recognize both common and emergent GI pathologies across age groups. Let's get started. The gastrointestinal tract is a long, hollow, muscular tube extending from the mouth to the anus. In abdominal sonography, we typically evaluate the stomach, small intestine, and large bowel. While ultrasound has limitations due to gas and deep location, it plays a crucial role in assessing wall thickness, luminal content, peristalsis, and vascularity, especially in pediatric and emergency settings. Let's begin with a foundational concept, bowel
