UGI Esophagus-ESOPHAGEAL VARICEAL TREATMENT USING A NOVEL DOPPLER PROBE METHOD

Video Transcription

Esophageal belly cell treatment using a novel Doppler approach method.  Varissal recurrence after endoscopic treatment is a frequent event. Endoscopic treatment assisted by endoscopic ultrasonography that can evaluate varissal size and hemodynamics  enables endoscopists to identify the varices to be treated. However, the assisted EUS method has issues related to its use.  It's time-consuming, it's complicated to use convex transducers, and it requires scope replacement for additional treatment. This picture reveals the new Doppler system.  The latest Doppler probe method uses a through-the-scope Doppler probe. The new Doppler method can evaluate the direction, waveform, and the amount of blood flow.  New Doppler method has advantages such as simple, non-invasive, and no requirements of scope replacement for additional treatment.  This slide represents the flow of new Doppler-assisted varissal treatment.  Case 1, a 58-year-old man with a history of esophageal varissal rupture had recurrence of esophageal varices.  He had undergone endoscopic varissal ligations, but recurrence of varices was observed.  We evaluated remarkable varices using a new Doppler method.  Massive blood flow was confirmed.  Additionally, we evaluated the inner side of its varices.  We found a site where Doppler flow increased.  We assumed there is a penetrating vein.  Evaluation after hemostasis was performed, and decrease of blood flow was confirmed. Case 2, a 49-year-old man with a history of gastric barista rupture had development  of esophageal baritis. Esophageal baritis that continues with the stomach is remarkably developed and evaluated Doppler method. Bleeding blood flow was confirmed.  We performed band-nagation.  Evaluation after hemostasis was performed. Massive blood flow still remained. We consider we need additional treatment. The second EVL was performed.  We evaluated blood flow again. The decrease of blood flow was confirmed. Both cases were treated effectively with band-nagation assisted with our novel Doppler flow method.

Video Summary

This video summary discusses the use of a novel Doppler approach for the treatment of esophageal varices. The current endoscopic treatment assisted by endoscopic ultrasonography (EUS) method has limitations such as being time-consuming, complicated to use convex transducers, and requiring scope replacement for additional treatment. The new Doppler method solves these issues by using a through-the-scope Doppler probe to evaluate the direction, waveform, and amount of blood flow. Two case studies demonstrate the effectiveness of the Doppler-assisted variceal treatment in evaluating varices, identifying penetrating veins, and achieving hemostasis. Overall, the new Doppler method offers advantages such as simplicity, non-invasiveness, and no need for scope replacement during treatment. (No credits provided)
