Video Tip: Radiofrequency Ablation for Gastric Antral Vascular Ectasia

Video Transcription

Video Summary

In this video, Dr. Samit Tiwani from Rockford Gastroenterology Associates discusses radiofrequency ablation (RFA) as a treatment option for gastric antral vascular ectasia (GAVE). GAVE is a rare cause of upper GI bleeding and can manifest as iron deficiency anemia or occult GI bleeding. Endoscopically, it appears as dilated mucosal blood vessels called watermelon stomach. RFA, initially used for Barrett's esophagus, has emerged as an alternative treatment for GAVE. It uses thermal therapy to destroy targeted tissue, achieving consistent depth of ablation. RFA can be used with various catheters attached to the endoscope. It provides ease of use and controlled treatment, but potential risks and complications should be considered.
