The main questions it aims to answer are:\n\nHow often does a routine postoperative chest X-ray change clinical management? Can lung ultrasound detect relevant postoperative findings as effectively as chest X-ray? Researchers will compare lung ultrasound results and the treatment decision that would have been made based on ultrasound alone with the actual treatment decision based on chest X-ray to see if using lung ultrasound first, with chest X-ray only when needed, could reduce radiation exposure and imaging costs without affecting care.\n\nParticipants will:\n\nHave a routine chest X-ray after surgery.
