We reviewed the perioperative outcomes, including the operative time, console time, conversion rates, and complications. The learning curves for operative and console times were assessed using a cumulative summation analysis.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The mean patient age was 71.5 years. Thirty-five and 18 patients underwent lobectomy and segmentectomy, respectively. The mean operative and console times were 207.1\u00a0min and 147.5\u00a0min, respectively. Two patients (4%) required conversion to an open thoracotomy. Two patients (4%) experienced Clavien-Dindo grade\u2009\u2265\u2009II postoperative complications, with no severe morbidity. A cumulative summation analysis indicated that the learning curve for lobectomy plateaued after the 14th case, whereas proficiency for all resections was achieved after 18\u201319 cases.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Anatomical lung resection using the da Vinci SP system can be safely performed with favorable short-term outcomes.
