Video Summary

In this video, the speaker discusses two thermal therapies used in gastrointestinal procedures: argon plasma coagulation (APC) and the gold probe. APC is used for small superficial lesions in the stomach, duodenum, small intestine, and colon. It ablates the surface mucosa using a cautery machine and pedal. It is not suitable for ulcer bleeds. APC utilizes ionized argon gas to deliver cautery only to the surface, minimizing deep tissue injury. The speaker demonstrates how to use APC, emphasizing the importance of a stable position and maintaining distance between the probe and mucosa. The gold probe is used for treating bleeding ulcers with visible vessels. It requires pressure against the lesion to collapse the vessel, followed by a continuous application of low-wattage energy to achieve thrombosis. The speaker demonstrates the use of the gold probe, highlighting the need for proper positioning and longer application time compared to other modalities. They also mention the use of epinephrine injection prior to using the gold probe to minimize immediate bleeding. The video emphasizes the importance of individualizing the treatment based on the patient and lesion characteristics and becoming comfortable with these modalities during fellowship.
