Endoscopic Tissue Sampling of the Upper GI Tract: From Forceps to Optical (DV053)-Endoscopic Tissue Sampling of the Upper GI Tract: From Forceps to Optical (DV053)

Video Transcription

Video Summary

The video discusses the importance of tissue sampling in gastrointestinal endoscopy and provides practical recommendations for endoscopic tissue sampling techniques and indications for the GI tract. It highlights the broad indications for tissue sampling, including suspicious mucosal tissue, assessment of tissue response to therapy, and confirmation of normal tissue. The video emphasizes the need to weigh the risks and benefits of tissue sampling in patients at high risk for bleeding or on antithrombotic agents.<br /><br />The video also discusses the classification of endoscopic procedures according to bleeding risk and the discontinuation of antithrombotic agents for different tissue sampling procedures. It mentions the importance of obtaining adequate biopsy samples for accurate diagnosis and provides information on various commercially available biopsy forceps.<br /><br />The use of methylene blue in detecting suspicious lesions in Barrett's esophagus and the surveillance of Barrett's esophagus are discussed. The video also covers tissue sampling techniques for gastric neoplasia and the use of endoscopic submucosal dissection for complete resection of subepithelial tumors.<br /><br />It further delves into the use of endoscopic ultrasound-guided needle biopsy for the diagnosis of mass lesions and the limitations and contraindications of this technique. The video also discusses optical biopsies, including narrowband imaging and confocal endomicroscopy, for predicting histopathology without tissue sampling.<br /><br />Overall, the video provides a comprehensive overview of tissue sampling techniques and their applications in gastrointestinal endoscopy.
