Clinically, according to the different types of patients’ surgery, the time that patients can eat leeks after surgery also makes a difference. First, if the patient performs body surface mass excision such as superficial lipoma, epidermoid cyst, hemangioma surgery. As the surgery does not affect the gastrointestinal function, in this case, 24 hours after the surgery, patients can eat a small amount of leeks, which will not cause serious impact on the human body. Second, if the patient due to intestinal diseases, and surgical treatment, such as acute suppurative appendicitis, surgical resection, acute suppurative cholecystitis or acute gastrointestinal tract perforation, post-surgery patients with gastrointestinal function is weak, premature intake of leeks, may cause the patient to appear abdominal pain, abdominal distension and other symptoms. It is recommended that the patient’s postoperative gastrointestinal function fully recovered, and then eat leeks safer.
