'scalpel'

Hemorrhoidectomy is surgery to remove hemorrhoids. You will be given general anesthesia or spinal anesthesia so that you will not feel pain. Incisions are made in the tissue around the hemorrhoid. The swollen vein inside the hemorrhoid is tied off to prevent bleeding, and the hemorrhoid is removed. The surgical area may be sewn closed or left open. Medicated gauze covers the wound. Surgery can be done with a knife (scalpel), a tool that uses electricity (cautery pencil), or a laser. There is a procedure that uses a circular stapling device to remove hemorrhoidal tissue and close the wound. No incision is made. In this procedure, the hemorrhoid is lifted and then "stapled" back into place in the anal canal. This surgery is called stapled hemorrhoidopexy. People who have stapled surgery may have less pain after surgery than people who have the traditional hemorrhoid surgery. But the stapled surgery is more expensive. And people who have stapled surgery are more likely to have hemorrhoids come back and need surgery again. Doppler-guided hemorrhoidectomy is a procedure that uses a scope with a special probe to locate the hemorrhoidal arteries so that less tissue is removed. Some studies show that it is less painful but more long term studies are needed to compare it with other procedures.

Male circumcision is an operation to remove the foreskin that covers the tip of the penis. The functions of the foreskin include protecting the head of the penis and contributing to sexual sensations. While recent research suggests that circumcision may bring some medical benefits, some doctors believe these are too small to justify surgery. A medical circumcision is a circumcision performed to treat a disease, such as pathological phimosis (lichen sclerosis), recurrent balanitis or recurrent urinary tract infections. A request circumcision is a circumcision performed for non-medical reasons, such as parental preference, religious reasons or to potentially prevent disease at some future time.There are different methods of circumcision. Either local or general anaesthesia should always be used. The procedure involves numbing the area with local anaesthetic creams or injection. A bell-shaped instrument is inserted under the foreskin to separate it from the penis. The foreskin is then removed using scissors or a scalpel. Alternatively, circumcision can be performed as a formal surgical procedure, using dissolving sutures or tissue glue.
