Video Transcription

Video Summary

The video provides a comprehensive overview of gastrointestinal (GI) endoscopy tools and procedures, focusing on upper endoscopy, colonoscopy, ERCP (endoscopic retrograde cholangiopancreatography), and endoscopic ultrasound (EUS). Upper endoscopy (EGD) examines the esophagus, stomach, and duodenum to diagnose issues like abdominal pain, reflux, bleeding, and foreign body removal. Colonoscopy inspects the colon and terminal ileum for polyps, inflammation, and bleeding; it's unique as a preventive measure by removing adenomatous polyps to prevent colon cancer progression.<br /><br />Various endoscopic tools include biopsy forceps, snares (cold and hot) for polyp removal, retrieval baskets, injection needles for submucosal lifting and medication, hemostatic clips, electrocautery probes, and band ligators for varices. Cold snare polypectomy is preferred due to less bleeding and better pathology preservation.<br /><br />Interventional procedures like ERCP access bile and pancreatic ducts for stone removal, dilation, stenting, and biopsy. EUS combines endoscopy with ultrasound to evaluate GI wall layers, stage cancers, guide biopsies, and perform therapeutic interventions such as drainage of pancreatic cysts.<br /><br />Advanced endoscopy techniques include third space endoscopy and submucosal dissection; balloon enteroscopy is used to reach the small intestine. The session also highlights clinical indications, procedural risks like perforation, polyp detection rates, and emerging technologies for comprehensive GI tract evaluation.
