Objective: To compare the perioperative outcomes of single-incision and multiple-incision thoracoscopic lobectomy and segmentectomy.
Background: Reports of single-incision thoracoscopic lobectomy and segmentectomy for lung cancer are limited, and a comparison between single-incision and multiple-incision thoracoscopic lobectomy or segmentectomy for lung cancer has not been previously reported.
Methods: From January 2005 to June 2013, a total of 233 patients with lung cancer underwent thoracoscopic lobectomy or segmentectomy via a single-incision or multiple-incision technique. A propensity-matched analysis, incorporating preoperative variables, was used to compare the short-term outcomes between single-incision and multiple-incision thoracoscopic lobectomy and segmentectomy.
Results: Overall, 50 patients underwent single-incision thoracoscopic pulmonary resections, including 35 lobectomies and 15 segmentectomies, and 183 patients underwent multiple-incision thoracoscopic lobectomy or segmentectomy between January 2005 and December 2011. Propensity matching produced 46 patients in each group. The length of hospital stay and the complication rate were not significantly different between the 2 groups. Single-incision thoracoscopic lobectomy and segmentectomy were associated with shorter operative time (P = 0.029), more numbers of lymph nodes (P = 0.032), and less intraoperative blood loss (P = 0.017) than with the multiple-incision approach. No in-hospital mortality occurred in either group.
Conclusions: Single-incision thoracoscopic lobectomy and segmentectomy are feasible, and perioperative outcomes are comparable with those of the multiple-incision approach.
