Robotic lobectomy: tips, pitfalls and troubleshooting

The robotic approach in thoracic surgery has rapidly gained popularity in recent years. As with the introduction of any new technology, this warrants not only adaptation of the operative technique itself, but also the evolution of appropriate troubleshooting strategies. A selected number of helpful tips and technical procedural manoeuvres have been compiled to prevent intraoperative problems, as well as to overcome challenging situations that can arise during robotic lobectomies. In robotic surgery, as opposed to open surgery or video-assisted thoracic surgery, these tips serve an important purpose for the operating surgeon, as well as the entire surgical team involved in the procedure. All the assembled recommendations have proved their effectiveness and have been successfully used by the authors in many procedures. Furthermore, these manoeuvres have been found to be of great importance in the training and proctoring of thoracic surgeons, fellows and residents (bed-side assistants). This guide of clearly arranged tips and troubleshooting strategies offers surgeons a useful tool to overcome difficult situations in robotic lobectomy and preferably improve the reproducibility and safety of their procedures

Robot-assisted resection of pulmonary sequestrations

Pulmonary sequestration is a rare congenital malformation and may cause recurrent infections and hemoptysis. Although video-assisted thoracic surgery (VATS) is feasible, some drawbacks remain, mainly dealing the managing of anomalous vessels. We describe the use of a robotic system (da Vinci Robotic System, Surgical Intuitive, Mountain View, CA, USA) in the treatment of four consecutive cases of pulmonary sequestration. © 2011 European Association for Cardio-Thoracic Surgery

Robotic lobectomy for lung cancer: Evolution in technique and technology

OBJECTIVES: The aim of this study was to analyse the results of robotic lobectomy for lung cancer. The evolution of technique and technology was evaluated. METHODS: During the period 2004-12, all patients who underwent robotic lobectomy for clinical early-stage lung cancer were retrospectively reviewed. The patients were divided into two groups. Group 1 included 69 patients operated by the first generation of surgical robotic system. Group 2 included 160 patients treated with the latest generation of surgical robotic system. Age, gender, comorbidities, operative time, docking time, conversion rate, morbidity, mortality and length of postoperative stay were compared in both groups. RESULTS: The two groups were homogeneous in terms of age, gender and comorbidities. Histopathological analysis showed 41 and 107 adenocarcinomas, 27 and 37 squamous cell carcinomas, 1 and 7 large cell carcinomas, in Groups 1 and 2, respectively, and 5 sarcomatoid carcinomas and 4 carcinoids in Group 2. The pathological stage for Group 1 was Stage I (48 cases), Stage II (17 cases) and Stage III (4 cases). For Group 2, Stage I was found in 115 cases, Stage II in 30 cases and Stage III in 15 cases. The mean operative time was 237 (standard deviation (SD) + 66.9) and 172 (SD ± 39.6) min for Groups 1 and 2 (P = 0.002), respectively. The conversion rates were, respectively, 10.1 and 5.6% (P = 0.21), mortality rates 1.4 and 0% (P = 0.30) and morbidity rates 22 and 15% (P = 0.12). The mean length of postoperative stay was 4.4 (SD ± 3.1) and 3.8 days (SD ± 2.2) (P = 0.26), respectively. CONCLUSIONS: This study suggests a positive trend in the outcomes for patients who underwent the upgraded robotic system surgery compared with those treated by the standard system. © The Author 2014.

Lung metastasectomy after colorectal cancer: prognostic impact of resection margin on long term survival, a retrospective cohort study.

BACKGROUND: Pulmonary metastasectomy is considered a potentially curative treatment for selected patients with metastatic colorectal cancer (CRC). Several prognostic factors have been analysed, but to date, it is still not well defined which is the optimal resection margin during lung metastasectomy (LM). This study analyses the long-term results and prognostic factors after LM in CRC patients with particular attention to the resection margins. Primary endpoint of this study is to assess the correlation between resection margins and long-term outcomes. METHODS: Observational cohort study on all proven cases of CRC lung metastases (2000-2016) resected with curative intent in a single centre. RESULTS: The series included 210 consecutive patients (M/F 133/77) with a mean age of 65.4 (± 9.96) years, 75% (159/210) of them with a solitary metastasis. Mean size of metastasis was 2.57 cm (± 1.45). One hundred sixty-eight patients underwent wedge resections (80%) and lymphadenectomy was carried out in 90 cases (42.9%). With a mean follow-up of 56 months (range 5-192), we observed a 1-, 3- and 5-year overall survival (OS) of 95%, 74% and 54%, respectively. The patients were divided into three groups according to the resection margin distance from the tumour: (a) ≥ 2 cm (145 cases); (b) < 2, ≥ 1 cm (37 cases); and (c) < 1 cm (12 cases). The OS was significantly different between the three groups (p = 0,020); univariate and multivariate analyses showed that a narrow resection margin was an independent prognostic factor of worse survival (p = 0.006 and HR 3.4 p = 0.009). CONCLUSIONS: Long-term survival of patients after LM is strongly associated with a greater distance between the lesion and the resection margin
