Surgical interventions are medical procedures that involve the use of instruments to treat injuries, diseases, or deformities. These procedures can be performed on various parts of the body and may involve cutting, removing, or repairing tissues. Common types of surgical interventions include appendectomy, knee replacement, and heart bypass surgery. Surgeries can be classified as either open surgery, which requires larger incisions, or minimally invasive surgery, which uses smaller incisions and specialized tools. The choice of surgical intervention depends on the patient's condition, the desired outcome, and the surgeon's expertise. Recovery times and risks vary based on the type of surgery performed.
