Whether a patient can fly after open surgery treatment depends on the different severity of the patient’s primary disease, whether the wound is fully recovered, and the patient’s overall recovery after surgery: 1. If the patient is operated under local anesthesia for superficial lipoma, tenosynovial cyst, fibroma and other benign diseases, the patient’s recovery after surgery is often smooth and the incision heals well, so he can fly for a short time 2. If the patient is treated with open surgery under general anesthesia for malignant lesions, such as malignant tumor of the stomach, malignant tumor of the lung or malignant tumor of the liver. The patient’s body is often weak after surgery and often accompanied by complications such as incisional infection fat liquefaction. If patients fly in an airplane it may be an aggravation of the disease, which is not conducive to the recovery of the incision, so it is not recommended for patients to fly.
