Postoperative lymphatic fluid usually flows for about a week, but it cannot be generalized, the specific situation needs to be decided according to the severity of the injury and the recovery situation. If the degree of lymphatic damage during surgery is mild, the patient’s own physical quality is strong, and local pressure is given in time as well as targeted treatment, a few patients with good recovery, the postoperative lymphatic fluid leakage will gradually subside in about 3-5 days, and in general most of the patients can gradually subside in about a week. However, if the degree of lymphatic damage is more severe and the patient’s own physical quality declines, the healing time will increase and the leakage will last longer and may take 2~3 weeks to gradually subside. When symptoms of lymphatic fluid leakage occur, it is recommended that targeted treatment under the guidance of a medical professional is beneficial to the recovery of the condition.
