Surgical Endoscopy.


BACKGROUND: Surgical resection is the gold standard for treatment of early-stage lung tumors. Different minimally invasive approaches are currently under investigation: In addition to conventional video-assisted thoracoscopic surgery (VATS), robotic technology with the da Vinci System has emerged over the past 10 years. METHODS: In this series, 26 patients (12 women and 14 men; median age, 65 years) underwent a robotic lobectomy for early-stage lung tumors (clinical stage IA or IB) or centrally located metastases. RESULTS: The resected lobes included four left upper lobes, six left lower lobes, eight right upper lobes, and eight right lower lobes. Five intraoperative conversions to open thoracotomy were performed due to one major bleeding, two minor bleedings, one variant course of the pulmonary artery, and one extended resection. The postoperative complications included two prolonged air leaks, one colonic perforation, and one atrial fibrillation. The median hospital stay was 11 days (range, 7-53 days). One 30-day mortality (3.8%) occurred due to respiratory failure. The overall median operative time was 228 min (range, 162-375 min). For the first five patients, the posterior approach was used. Thereafter, the authors switched to an anterior approach, thus enabling an easier hilar dissection. Technical modification within this series also included the introduction of a new vessel sealing device. CONCLUSION: Robotic lobectomy was proved to be feasible and safe in our initial series in a learning curve setting. Changes in patient positioning and approach as well as technical modifications resulted in shorter operative times. A longer follow-up period and randomized controlled trials are necessary to evaluate a potential benefit over open and conventional VATS approaches.

Objectives: We investigated the feasibility and safety of four-arm robotic lung lobectomy in patients with lung cancer and described the robotic lobectomy technique with mediastinal lymph node dissection. Methods: Over 21 months, 54 patients underwent robotic lobectomy for early-stage lung cancer at our institute. We used a da Vinci Robotic System (Intuitive Surgical, Inc, Mountain View, Calif) with three ports plus one utility incision to isolate hilum elements and perform vascular and bronchial resection using standard endoscopic staplers. Standard mediastinal lymph node dissection was performed subsequently. Surgical outcomes were compared with those in 54 patients who underwent open surgery over the same period and were matched to the robotic group using propensity scores for a series of preoperative variables. Results: Conversion to open surgery was necessary in 7 (13%) cases. Postoperative complications (11/54, 20%, in each group) and median number of lymph nodes removed (17.5 robotic vs 17 open) were similar in the 2 groups. Median robotic operating time decreased by 43 minutes (P = .02) from first tertile (18 patients) to the second-plus-third tertile (36 patients). Median postoperative hospitalization was significantly shorter after robotic (excluding first tertile) than after open operations (4.5 days vs 6 days; P = .002). Conclusions: Robotic lobectomy with lymph node dissection is practicable, safe, and associated with shorter postoperative hospitalization than open surgery. From the number of lymph nodes removed it also appears oncologically acceptable for early lung cancer. Benefits in terms of postoperative pain, respiratory function, and quality of life still require evaluation. We expect that technologic developments will further simplify the robotic procedure. © 2010 The American Association for Thoracic Surgery.
