First Rib Resection for Thoracic Outlet Syndrome: The Robotic Approach.

OBJECTIVE: First rib resection is a well-recognized treatment option for thoracic outlet syndrome (TOS). In case of a vascular insufficiency that can be provoked and/or progressive neurologic symptoms without response to conservative treatment, surgical decompression of the space between the clavicle and the first rib is indicated. The aim of this paper is to present our experience with a new minimally invasive robotic approach using the da Vinci Surgical System®. METHODS: Between January 2015 and October 2017, eight consecutive first rib resections in seven patients were performed at our institution. Four patients presented with neurologic (one bilateral), and three patients with vascular (venous) impairment. In all cases, a transthoracic robotic-assisted approach was used. The first rib was removed using a 3-port robotic approach with an additional 2-cm axillary incision in the first six patients. The latest resection was performed through only three thoracic ports. RESULTS: Median operative time was 108 min, and the median hospital stay was 2 days. Postoperative courses were uneventful in all patients. Clinical follow-up examinations showed relief of symptoms in all nonspecific TOS patients, and duplex ultrasonography confirmed complete vein patency in the remaining patients 3 months after surgery. CONCLUSIONS: While there are limitations in conventional transaxillary, subclavicular and supraclavicular approaches in the first rib resection, the robotic method is not only less invasive but also allows better exposure and visualization of the first rib. Furthermore, the technique takes advantage of the benefits of the da Vinci Surgical System® in terms of 3D visualization and improved instrument maneuverability. Our early experience clearly demonstrates these advantages, which are also supported by the very good outcomes.

Late infections after dynamic stabilization of the lumbar spine with Dynesys.

INTRODUCTION: Dynamic stabilization of the spine was developed as an alternative to rigid fusion in chronic back pain to reduce the risk of adjacent segment degeneration. Dynamic neutralization system (Dynesys, Zimmer CH) is one of the most popular systems available, but some midterm studies show revision rates as high as 30 %. Some late infectious complications in our patients prompted us to review them systematically. Propionibacterium recently has been shown to cause subtle infections of prosthetic material. MATERIALS AND METHODS: Here, we report on a consecutive series of 50 Dynesys implants. In a median follow-up of 51 months (range 0-91), we identified 12 infectious and 11 non-infectious complications necessitating reoperation or removal of the implant in 17 patients. RESULTS: Material infections occurred after a median of 52 months (2-77) and were due to Propionibacterium alone (n = 4) or in combination (n = 3) in seven out of 11 patients. Clinical presentation combines new or increasing pain associated with signs of screw loosening on conventional X-rays; however, as many as 73.5 % of patients present some degree of screw loosening without being at all symptomatic of infection. CONCLUSION: The high rate of late infections with low-grade germs and the frequency of screw loosening signs made us suspect a lack of integration at the bone-screw interface. Surgeons should be suspicious if the patient presents a combination of new or increasing pain and signs of screw loosening, and aggressive revision is recommended in these cases.

Combination of endobronchial bronchoscopic debulking and bronchoplastic segmentectomy of an obstructive neuroendocrine tumour: probably the least invasive approach.

We report the case of a female patient with an obstructing well-differentiated neuroendocrine tumour in the apical segment of the completely atelectatic right lower lobe. Bronchoscopic debulking of the tumour lead to re-ventilation of the remaining lobe, allowing to perform a lung-sparing bronchoplastic resection of the affected segment by uniportal video-assisted thoracic surgery.

Bilateral thoracic duct ligation for persisting postoperative chylothorax.

Herein, we report the case of a patient with persistent postoperative chylothorax despite right supradiaphragmal ligation of the thoracic duct. Computed tomography lymphangiography after lipiodol injection demonstrated a correctly ligated right thoracic duct but an anatomical variation with patent left-sided thoracic duct, which was successfully ligated afterwards by video-assisted thoracic surgery.

Dynamic stenosis of the right main bronchus in a 3-month-old child: a tracheobronchial sleeve resection under venovenous extracorporeal membrane oxygenation.

We report the case of a boy with congenital dynamic stenosis of the right main bronchus. The operation was postponed to a later date, when the patient was in a better clinical position to tolerate surgery. A tracheobronchial sleeve resection under dual-lumen venovenous extracorporeal membrane oxygenation was performed.

Oncological results of full thoracoscopic major pulmonary resections for clinical Stage I non-small-cell lung cancer.

OBJECTIVES: The full thoracoscopic approach to major pulmonary resections is considered challenging and controversial as it might compromise oncological outcomes. The aim of this work was to analyse the results of a full thoracoscopic technique in terms of nodal upstaging and survival in patients with non-small-cell lung carcinoma (NSCLC). METHODS: All patients who underwent a full thoracoscopic major pulmonary resection for NSCLC between 2007 and August 2016 were analysed from an 'intent-to-treat' prospective database. Overall survival and disease-free survival were estimated using the Kaplan-Meier curves and comparisons in survival using the log-rank test. RESULTS: A total of 648 patients met the inclusion criteria, of whom 621 patients had clinical Stage I and 27 had higher stages (16 oligometastatic patients were excluded from the analysis, 11 cT3 or cT4). The mean follow-up was 34.5 months. There were 40 conversions to thoracotomy (6.3%). Thirty-day or in-hospital mortality was 0.95%. Complications occurred in 29.3% of patients. On pathological examination, 22.5% of clinical Stage I patients were upstaged. Nodal upstaging to N1 or N2 was observed in 15.8% of clinical Stage I patients. Five-year overall survival of the whole cohort was 75% and was significantly different between clinical Stages IA (76%) and IB (70.9%). For tumours <2 cm, no significant difference in overall survival was found for the segmentectomy group compared to the lobectomy group: 74% versus 78.9% (P = 0.634). CONCLUSIONS: Long-term survival is not compromised by a full thoracoscopic approach. Our results compared favourably with those of video-assisted techniques.
