Project description:Use of low-dose CT scan allows detection of lung cancer at early stages, enabling a more conservative surgery and a better long-term survival in those patients. In this scenario, intentional anatomical segmentectomy is gaining consent over standard lobectomy among surgeons. A minimally invasive approach such as VATS reduced invasiveness and complication rate compared to open surgery, but this technique comes also with some disadvantages in terms of dexterity and intuitiveness. Robotic surgery allows to overcome those limitations, making segmentectomies easier and safer to perform. In addition, it offers the possibility to utilize intravenous indocyanine green to define the intersegmental plane, allowing a more precise surgery. We reviewed the literature and describe the technique of the robot assisted segmentectomy with a focus on the new technologies available nowadays.

Project description:BackgroundPulmonary segmentectomy for a lung with an incomplete interlobar fissure may complicate persistent air leakage. The fissureless technique is often used in lobectomy to prevent persistent air leakage. We herein describe successful use of the fissureless technique for segmentectomy with the aid of a robotic surgical system.Case presentationA 63-year-old man was clinically diagnosed with early-stage lung cancer for which lingular segmentectomy was indicated. A preoperative image revealed a lung with an incomplete fissure. Based on three-dimensional reconstruction imaging, we planned to divide the hilum structures in the order of the pulmonary vein, bronchus, and pulmonary artery and finally resect the lung parenchyma by dividing the intersegmental plane and interlobar fissure. This fissureless technique was successfully conducted using a robotic surgical system. The patient did not develop persistent air leakage and was alive without recurrence 1 year after segmentectomy.ConclusionsThe fissureless technique may be a useful option in segmentectomy for a lung with an incomplete interlobar fissure.

Project description:BackgroundRobotic anatomic segmentectomy (RATS) for early-stage lung cancer is being increasingly performed in spite of limited published evidence. To evaluate its safety and oncologic efficacy, we compared the outcomes of both RATS and video-assisted thoracoscopic (VATS) segmentectomy in patients with small-sized (<2 cm) peripheral stage IA lung cancer.MethodsFrom November 2011 to January 2018, a total of 130 patients with resected stage IA non-small cell lung cancer (NSCLC) who underwent RATS (n=50) and VATS (n=80) pulmonary segmentectomy were included. Clinicopathologic data, recurrence rate, and survival were recorded.ResultsThe demographics, pulmonary function, comorbidity, and tumor size were similar between RATS segmentectomy and VATS segmentectomy. The surgery time, intensive care unit stay, hospital stay, and blood loss were reduced in the RATS group compared to the VATS group. The number of totally dissected lymph nodes and postoperative complications were similar between the 2 groups. There was no operative mortality. The intensity of narcotic use during hospital stay and the time to return to routine daily activities were also reduced in the RATS group. There was no recurrence observed in the RATS group during the median 38-month follow-up period; meanwhile, during a median 85-month follow-up period in the VATS group, local recurrence and distant recurrence was observed in 2 patients (2.5%) and 3 patients (3.75%) respectively. There was no significant difference in the 5-year recurrence-free survival between the RATS and VATS groups (100% vs. 93.75%; P>0.05).ConclusionsRATS can be performed safely and effectively in patients with early-stage NSCLC. The reduced narcotic use and earlier return to routine daily activities of RATS patients might reflect its less traumatic nature as compared to VATS. For stage IA disease with small tumors (<2 cm), segmentectomy performed by RATS has better oncologic efficacy when compared to VATS, although in this study, this difference did not reach statistical difference.

Project description:Posterior basal (S10) segmentectomy is one of the most challenging (and uncommon) types of pulmonary segmentectomy. Here, we present two key tips for facilitating a uniportal operation. The first is a full understanding of the relative locations of the pulmonary vessels and bronchi (as revealed by preoperative three-dimensional computed tomography/broncho-angiography), and the other is the use of "suction-guided stapling" to dissect and divide the peripheral pulmonary vessels and bronchi. We describe the successful postoperative course of a patient who was so treated.

Project description:BackgroundPulmonary segmentectomy provides an anatomic lung resection while avoiding removal of excess normal lung tissue. This may be beneficial in patients with minimal pulmonary reserve who present with early-stage non-small cell lung cancer (NSCLC). However, the operative performance of a segmentectomy using a video-assisted thoracoscopic approach can be technically challenging. We hypothesized that introduction of the robotic surgical system would facilitate the performance of a segmentectomy as measured by an increase in the proportion of segmentectomies being pursued.MethodsWe completed a retrospective analysis of thoracoscopic and robotic anatomic lung resections, including lobectomies and segmentectomies, performed in patients with primary lung cancer from the time of initiation of the robotic thoracic surgery program in November 2017 to November 2019. We compared the proportion of thoracoscopic and robotic segmentectomies performed during the first year compared to the second year of the data collection period.ResultsA total of 138 thoracoscopic and robotic anatomic lung resections were performed for primary lung cancer. Types of lung cancer resected (adenocarcinoma, squamous cell carcinoma, or other), tumor size based on clinical T staging (T1-T4), and tumor location were not significantly different between years (P=0.44, P=0.98, and P=0.26, respectively). The proportion of segmentectomies increased from 8.6% during the first year to 25.0% during the second year (P=0.01). One out of 6 (16.7%) segmentectomies were performed using the robot during the first year versus 15 out of 17 (88.2%) during the second year (P=0.003).ConclusionsUse of the robot led to a significant increase in the number of segmentectomies performed in patients undergoing anatomic lung resection. With increasing lung cancer awareness and widely available screening, a greater number of small, early-stage tumors suitable for segmentectomy will likely be detected. We conclude that robotic-assisted surgery may facilitate the challenges of performing a minimally invasive segmentectomy.

Project description:Open onlay ventral hernia repair is still one of the most-used surgical techniques for the repair of hernias worldwide. The robotic anterior component separation technique uses the surgeon's usual anatomical expertise on onlay mesh placement with the manipulation and advantages of minimally invasive surgery. It maintains the precepts of reestablishment the midline integrity and insertion of mesh in the preaponeurotic space, without contact with the viscera. The use of this technique is simple and quite reproducible if you compare it with other techniques. Also, the time spent in surgery does not last long.

Project description:BACKGROUND:Lung segmentectomy is increasingly used to resect lung nodules. Video-assisted thoracic surgery (VATS) is widely chosen to performing lung segmentectomy, while robotic assisted thoracoscopic (RATS) was also one useful and practical method. There article was intended to compared the short-time outcomes of RATS and VATS in lung segmentectomy. METHODS:The patients with lung nodules underwent segmentectomy by either RATS or VATS from January 2016 to April 2017 were studied. Baseline characteristics and short-time outcomes (dissected lymph nodes, postoperative duration of drainage, postoperative hospital stay, incidence of pro-longed air leak, atrial fibrillation and pneumonia) were compared. RESULTS:166 patients were included in this study: 81 patients underwent RATS segmentectomy while 85 underwent VATS segmentectomy. The number of lymph nodes dissected in RATS group was more than in VATS group ?(13.07±5.08) vs (10.81±5.74), P=0.010?. The incidence of some postoperative complications such as pro-longed air leak, atrial fibrillation was not significant different between the two approaches. CONCLUSIONS:Compared with VATS, RATS has similar safety and operability, and the number of lymphadenectomy is significantly more than that of VATS.

Project description:ObjectiveTo optimize surgical outcomes and minimize complications in complex segmentectomy of the left upper lobe, we investigated the topographical anatomy of the left upper lobe and developed a segmentectomy-oriented anatomical model.MethodsA state-of-the-art 3-dimensional computed tomography workstation was used to visualize the intersegmental planes and associated veins to categorize the anatomical patterns influencing surgical procedures during left upper lobe segmentectomy. This included the central vein affecting S1+2 (apicoposterior segment) segmentectomy, the transverse S3 (anterior segment) affecting S3 segmentectomy, and other venous branching patterns in 395 patients who underwent thoracic surgery at our institution.ResultsThe central vein was observed in 32% of the patients, necessitating access from the interlobar area after segmental artery and bronchus division. Transverse S3 incidence was 27%, revealing that only one-third of the patients required complete left upper lobe transection between S4 and S3 during S3 segmentectomy. A significant negative correlation was observed between the presence of transverse S3 and the central vein (<10% of patients with the central vein had transverse S3 and vice versa). In 6% of patients, the lingular segmental veins partially or entirely drained into the inferior pulmonary vein, potentially causing excessive or insufficient resection during surgery.ConclusionsThis study offers valuable insights into the topographic anatomy of the left upper lobe and presents a segmentectomy-oriented anatomical model for complex segmentectomies. Our approach enables a more precise and individualized surgical planning for patients undergoing segmentectomy based on their unique anatomy, which could thereby lead to improved patient outcomes.
