6_Endoscopic Submucosal Dissection of Barrett's Neoplasia

Video Transcription

Video Summary

In this video, a segment of barrettes with a large nodule is shown. The nodule is concerning as it may be a submucosal invasive cancer. Acetic acid spray is used to identify any other neoplastic areas. The nodular area does not respond well to acetic acid, indicating potential malignancy. The margins of the nodule are marked with a dual knife, and a submucosal injection is performed to lift the area. The endoscopist then begins mucosal incision and submucosal dissection using a dual knife and hook knife. Hemostasis is achieved with a coag grasper. The lesion is resected, and the ESD base is assessed for any issues. The specimen is then sent for histopathology. No credits were mentioned in the transcript.
