Objective To investigate the value of VATS and argon-helium knife cryotherapy in the treatment of isolated pulmonary nodules. Methods A retrospective analysis was performed on 20 patients with solitary pulmonary nodules in our hospital from January 2023 to January 2024, and the patients were divided into control group (10 cases) and observation group (10 cases) according to the order of admission. The observation group was treated with VATS and the control group was treated with argon-helium knife cryotherapy. The surgical indexes and postoperative pain scores of the two groups were compared. Results Incision length, operation time, drainage tube drainage time, blood loss, postoperative dosage of pethidine, number of lymph node dissection, hospitalization days and postoperative drainage volume were significantly lower in the observation group than in the control group (P < 0.05). The pain score of the observation group was lower than that of the control group (P < 0.05). Conclusion VATS is more effective in the treatment of isolated pulmonary nodules and can be popularized.
