Emergency surgery refers to surgical procedures that need to be performed urgently due to life-threatening conditions or severe complications. These surgeries are typically performed in response to trauma, acute illnesses, or sudden medical emergencies that require immediate attention. Emergency surgeries are often performed in situations where delaying treatment could result in serious harm or death to the patient. Common examples of emergency surgeries include operations for appendicitis, traumatic injuries, perforated ulcers, and obstructed bowels. Emergency surgery requires a high level of expertise and quick decision-making from the surgical team to ensure the best possible outcome for the patient.
