Electrosurgery is a technique commonly used in flexible endoscopy procedures for diagnostic and therapeutic purposes. It involves the application of high-frequency electrical current to cut, coagulate, or ablate tissues. Electrosurgery can be performed using various devices, such as electrocautery units, electrocoagulation devices, and electrosurgical generators. Flexible endoscopy, which includes procedures like esophagogastroduodenoscopy (EGD) and colonoscopy, often incorporates electrosurgical tools for a range of applications.
