There is no fastest way to treat a lymphocyst, and the choice of medication or surgery needs to be made based on the patient’s cyst condition. Lymphocysts are caused by rupture of tissue lymphatic vessels, leakage of lymphatic fluid, and accumulation with local tissues. If the size of the cyst is small and not infected, it can be treated with anti-inflammatory drugs such as indomethacin suppositories and regular checkups; if the cyst is infected, it can be treated with anti-inflammatory drugs combined with puncture and drainage; if the tumor is metastatic or recurrent, it can be treated with chemotherapeutic drugs and targeting drugs, and it can be treated with surgical resection if the conservative treatment is not effective. After the occurrence of lymphocysts, it is recommended that patients go to the hospital in a timely manner, need to determine the severity of the condition, and then decide how to treat, patients do not need to be treated, can be regularly reviewed, some patients need surgical treatment.
