Surgical intervention refers to a medical procedure that involves the use of instruments to treat injuries, diseases, or deformities. This can include operations such as appendectomy to remove the appendix, or bypass surgery to improve blood flow in the heart. Surgical interventions can be performed in various settings, including hospitals and outpatient clinics. These procedures can be classified as either invasive, where incisions are made in the body, or minimally invasive, which often use smaller incisions and specialized tools. The goal of surgical intervention is to improve a patient's health, alleviate pain, or restore function.
