Abstract
BACKGROUND: Nonintubated spontaneous ventilation video-assisted thoracoscopic surgery (NI-VATS) has been investigated to reduce the adverse effects of tracheal intubation, mechanical ventilation, and general anesthesia in several thoracic diseases. We comparatively assess the comparison between NI-VATS vs intubated anesthesia VATS (I-VATS) on early outcomes of mediastinal lesion resection. METHODS: Patients who underwent VATS resection for a mediastinal tumor between December 2015 and September 2018 were retrospectively included for analysis. Patients were divided into two groups according to anesthesia ventilation type: NI-VATS and I-VATS. Propensity score matching was applied to eliminate population bias. Intraoperative and postoperative variables were compared. RESULTS: A total of 198 patients was included; 75 patients underwent NI-VATS and 123 patients underwent I-VATS. After propensity score matching, both anesthesia time (173.81 vs 227.37 minutes, P < .001) and operation time (82.82 vs 133.49 minutes, P < .001) were shorter in the NI-VATS group. Bleeding (51.80 mL vs 56.73 mL, P = .90) and postoperative morbidity (10.9% vs 15.6%, P = .57) were similar between groups. Chest tube duration (1.11 vs 1.54 days, P = .04) was shorter in the NI-VATS group. Hospital duration after surgery (3.15 vs 5.35 days, P < .001) was shorter in the NI-VATS group. D-dimer after surgery was significantly higher in both groups, but NI-VATS decreased the change (577 vs 1624 μg/L, P < .001). Furthermore, a decrease in the use of postoperative opioids analgesics was seen in the NI-VATS group (31% vs 51%, P = .023). CONCLUSIONS: Mediastinal tumor resection is safe and feasible under NI-VATS. Better short-term outcomes suggest NI-VATS facilitates a more rapid recovery. Further multicenter prospective randomized investigation is warranted.
