Major surgery refers to any surgical procedure that involves significant risk, a longer recovery time, and often requires general anesthesia. Think of it as a major repair job on a car's engine versus a simple oil change. It typically involves opening a body cavity or altering major organ systems. Examples include heart surgery, organ transplants, and complex orthopedic procedures. Due to the complexity and potential risks, major surgery requires careful planning and a skilled surgical team. It can be life-saving but also carries potential complications.
