Surgical options for patients with anal fissures include anal fissure resection, and internal anal sphincter block. The electric knife is just one tool used in the surgery, and the surgery can be performed either with the electric knife or with a regular scalpel. The electric knife can be used during anal fissure surgery, not only for cutting, but also for stopping bleeding areas, which is more practical than a regular scalpel. However, when using the scalpel, it is important to avoid cauterizing too widely and too deeply. Anal fissure surgery is not completely sure whether to use an electric knife or an ordinary scalpel, but is mainly determined by the operating habits of the surgeon, the need for surgery and the constraints of the surgical conditions. Whether to use electric knife or ordinary scalpel, it is recommended that the patient go to the hospital and consult a professional doctor; if you suffer from anal fissure, you should consult a doctor in time and take active treatment so as to avoid delaying the condition.
