Advanced Endoscopy Gastroenterologists routinely perform complex procedures such as endoscopic ultrasound (EUS), endoscopic retrograde cholangiopancreatography (ERCP), endoscopic mucosal resection (EMR), and endoscopic submucosal dissection (ESD). These techniques allow for minimally invasive diagnosis and treatment of gastrointestinal cancers, strictures, and bile duct disorders, often reducing the need for surgical intervention. Unlike standard diagnostic endoscopies, advanced procedures require specialized training and equipment and often involve collaboration with surgeons, radiologists, and oncologists. By handling more complex cases, these specialists play a crucial role in multidisciplinary care teams and contribute to improved patient outcomes.
