Single- versus multi-port video-assisted thoracic surgery for pulmonary aspergilloma: a propensity-matched study.

Abstract

The utilization of single-port video-assisted thoracic surgery for pulmonary aspergilloma (PA) has not been well studied. The study was performed to evaluate the safety and feasibility of it for PA compared with multi-port video thoracic-assisted surgery. From August 2007 to December 2019, consecutive PA patients receiving surgeries at Shanghai Pulmonary Hospital were enrolled retrospectively. Propensity score matching based on preoperative clinical variables was utilized to compare perioperative and long-term outcomes. In all 358 patients, a total of 63 patients underwent single-port video-assisted thoracic surgery, and 63 out of 145 patients for multi-port surgeries were paired with the single-port video-assisted thoracic surgery recipients. The median follow-up period was 40 months (range, 2-140 months). Patients receiving single-port video-assisted thoracic surgery showed a similar operation time, intraoperative blood loss, drainage duration and drainage volume to those of multi-port video-assisted thoracic surgery recipients (P > 0.05). Patients undergoing lobectomy by single-port approach experienced a shorter postoperative hospital stay {4.9 [standard deviation (SD): 2.0] vs 5.9 (SD: 2.3), P = 0.014}. The average postoperative pain scores [day 0: 2.6 (SD: 0.7) vs 3.1 (SD: 0.8), day 3: 4.0 (SD: 0.9) vs 4.8 (SD: 3.9), day 7: 2.2 (SD: 0.5) vs 3.1 (SD: 0.8), P < 0.001] and the number of days that patients required analgesic agents [3.0 (SD: 2.2) vs 4.8 (SD: 2.1), P < 0.001] were also decreased in the single-port video-assisted thoracic surgery group. Single-port video-assisted thoracic surgery is a safe and feasible alternative to multi-port video-assisted thoracic surgery for simple PA and selected complex ones, with a potential advantage of reduced postoperative pain.
