Introduction The therapeutic basis of all electrosurgery is the use of high frequency, alternating electric current to produce heating in living cells. The heating can be manipulated to achieve a desired tissue effect such as cutting, tissue ablation, desiccation, or…
10.1 Introduction A general outline of this chapter includes a brief background followed by historical trends of endoscopic ablation (with the exception of radiofrequency ablation and cryospray ablation, which are covered in chapter 11, chapter 12 : Radiofrequency Ablation and…
Key points Ultrasound is mechanical energy in the form of vibrations that propagate through a medium such as tissue. Ultrasound interacts with tissue by undergoing absorption, reflection, refraction, and scattering and produces an image representative of tissue structure. Imaging artifacts…
