Endoscopy Technician Curriculum Sampler-HCC 1475-27. Band ligator movie

Video Transcription

Video Summary

The video discusses the use of band ligators in medical procedures. Band ligators are used to ligate or tie off blood vessels to prevent bleeding or treat bleeding. They have various applications, including the control of esophageal variceal bleeding, arterial bleeding, diverticular bleeding, dullafoil bleeding, resection of flat lesions, and management of rectal carcinoids. The video explains the anatomy of the portal venous system and how varices (enlarged veins) form in the esophagus due to liver cirrhosis. It highlights the importance of understanding the venous anatomy of the GE junction and lower esophageal segment for endoscopists performing band ligation. The video also provides a step-by-step guide on how to set up a band ligator and place bands, emphasizing the need to keep the ligator in a two-way position during the setup and only switching to the firing position when ready to deploy the bands. The recommended interval for banding to prevent or control variceal bleeding is two to eight weeks until obliteration. Possible side effects include chest discomfort and difficulty swallowing, but rare cases of premature band falling off and bleeding can occur. The video also briefly mentions band ligation for other applications, such as treating bleeding from arterial sources and performing endoscopic mucosal resection (EMR) in patients with Barrett's esophagus.
