Surgery is part of the practice of medicine and is used to structurally alter the human body through incision or destruction of tissues. Surgery is also defined as the diagnosis or treatment of conditions or disease processes using any instrument that causes localized alteration or transportation of live human tissue, such as lasers, ultrasound, ionizing radiation, scalpels, probes, and needles. Examples of surgery include the removal of a tumor, the opening of a blockage in your intestine, or the attachment of a blood vessel in a new location to help blood flow to a part of your body. Mostly hemostatic forceps and other grasping tools are used in above mentioned surgeries. Emergency Surgery is for life-threatening problems, such as a burst artery, and is treated immediately. Urgent Surgery is performed for conditions that require immediate attention.
