Background

Surgical treatment is thought to be the most effective strategy for multiple small nodules. However, in general, one-stage bilateral resection is not recommended due to its highly invasive nature.

Methods

Clinical records of patients undergoing one-stage bilateral resections of multiple pulmonary nodules between January 2009 and September 2014 in a single institution were retrospectively reviewed.

Results

Simultaneous bilateral pulmonary resection by conventional video-assisted thoracic surgery (VATS) was undertaken in 29 patients. Ground glass opacity (GGO) accounted for 71.9%(46/64) of total lesions, including 26 pure GGO and 20 mixed GGO lesions. One case underwent bilateral lobectomy that was complicated by postoperative dyspnea. Lobar-sublobar (L/SL) resection and bilateral sublobar resection (SL-SL) were conducted in 16 and 12 cases, respectively, and most of these cases had …
