Virtual Demonstration 2 - Thermal Therapies APC

Video Transcription

Video Summary

The video features a discussion on thermal therapies, specifically argon plasma coagulation (APC) and the use of a gold probe for cauterization. APC is used to treat small superficial lesions in the stomach, duodenum, small intestine, and colon by ablating the surface mucosa using cautery. It is not typically used for ulcer bleeds, as other modalities such as injection and clips are more suitable. APC involves the use of argon gas, which is ionized through a tungsten wire in the catheter, and cautery is delivered through this gas. The appeal of APC is that it only causes a superficial burn and does not lead to deep tissue injury. The gold probe, on the other hand, is used for cauterizing bleeding ulcers when clips are not effective. It is a bipolar device that delivers low wattage energy to collapse and thrombose vessels. The video provides a demonstration of using both APC and the gold probe.
