Electro surgery has gained popularity in modern medicine in both open and laparoscopic surgery, due to its cost efficiency, easy availability and versatile applications. Initially, laparoscopic surgeons used suturing, then titanium clips and laparoscopic stapling devices to aid their surgery. The first used energy source for haemostasis during surgery was electro cautery. Monopolar is widely employed in laparoscopic surgeries for haemostasis in which continuous waveform results in tissue cutting whereas interrupted waveform is used for coagulation. In bipolar energy sources, current passes between two active electrodes in the instrument but in monopolar, the return current travels through patient’s body. Bipolar device is associated with minimum collateral spread, reduced risk of interference with other devices and better coagulation.
