Electrosurgical treatment of anal lesions
Electrosurgical treatment of AIN lesions usually involves the removal of anal lesions by ablation, coagulation or fulguration.
Electrothermal ablation is a procedure that allows the removal of anal condyloma and other anal intraepithelial lesions by means of thin low-voltage electrified blades or needle tips. The treatment aim is the removal of neoplastic or suspicious anal lesions and can be associated with a biopsy.
Electrothermal coagulation thermally coagulates and seals blood vessels connected with AIN lesions by means of small electrosurgical probes. The treatment aims at eliminating or reducing blood flow to the anal lesion.
Electrothermal fulguration thermally fulgurates and seals blood vessels connected with AIN lesions by means of dedicated electrosurgical probes. The treatment aims at eliminating or reducing blood flow to the anal lesion. It is normally used for larger surface hemostasis.
Electrosurgical treatment of anal lesions during HRA
Thanks to the latest technological advances, electrothermal removal of AIN lesions can today be performed during High Resolution Anoscopy (HRA) by means of special electrosurgical modules used with different electrosurgical probes.
High-resolution Anoscopy allows for the precise identification of lesions, while the electrosurgical unit, in combination with different types of probes, makes it possible to remove or reduce lesions by electrothermal ablation, fulguration or coagulation.
Smoke Evacuation during electrosurgical treatment of AIN lesions
During the electrosurgical removal of AIN lesions, the surgeon should use a smoke evacuation device to remove potentially harmful surgical smoke from the air.
Evidence-based literature reviews highlight the harmful effects of exposure to diathermy plumes, i.e. surgical smoke.
Likewise, available clinical data indicates that dedicated smoke extraction devices are effective at reducing the levels of diathermy plumes during various surgical procedures.
Therefore smoke evacuators play a fundamental role in increasing the safety of healthcare professional during AIN lesions surgery.
Today ablation kits are combined with compact and light-weighted smoke evacuators to prevent the hazards of surgical smokes both in an outpatient setting and in operating rooms.
Furthermore, new generation smoke evacuating systems allow to suction both smoke and body fluids.
