Surgery that penetrates and exposes a body cavity or produces substantial physical impairment is described as what kind of surgery?

The definition of surgery that penetrates and exposes a body cavity or causes substantial physical impairment aligns with the characteristics of major surgery. This type of surgery typically involves significant procedures that require a longer recovery period and often entails more risk and complexity compared to minor surgeries. Major surgeries can include operations such as open-heart surgery or abdominal surgery, which generally have a greater impact on the patient's body and necessitate careful postoperative management and monitoring.

On the other hand, minor surgery typically involves less invasive techniques that do not penetrate major body cavities and generally result in minimal physical impairment or recovery time. Experimental surgery refers to procedures that are not yet established or widely practiced, focusing on research rather than standard care, whereas elective surgery involves procedures that are scheduled in advance and are not performed due to an immediate medical necessity, rather than the complexity or invasiveness of the procedure itself.
