Pain outcomes of outside-the-cage robotic thoracic surgery: a prospective matched-cohort study

Management of acute and chronic pain after thoracic surgery for pulmonary resection or thymectomy remains a challenge for both thoracic surgeons and anesthesiologists. Advances in minimally invasive robotic procedures have made subcostal outside-the-cage (OTC) resections possible, but the procedure’s pain benefits have not been previously measured. A single-center cohort was consented to undergo robotic-assisted thoracoscopic surgery (RATS) with an OTC or transthoracic (TT) approach. On every post-operative day (POD), patients were asked to complete the visual analog scale (VAS) of pain, assigning a score of 0–10 with higher scores equaling higher pain intensity. Additionally, patients’ opioid consumption was recorded and classified using morphine equivalent dose (MED). Descriptive statistics of demographics, Mann–Whitney, and Chi-squared tests were performed in a matched analysis. Altogether, 50 OTC patients and 50 TT patients were included. For each group, 1 pneumonectomy, 19 lobectomies, 10 segmentectomies, and 20 thymectomies were performed. Between groups, most were male (n = 54; p = 0.42) and there were no differences in American Society of Anesthesiologists scores (p = 0.51), or tobacco consumption (p = 0.45). Patients who received an OTC approach experienced significantly lower pain scores on POD-0 (p = 0.001), POD-1 (p < 0.001), and POD-2 (p < 0.001). POD-3 OTC VAS scores were not different from those of the TT group (p = 0.09). Similarly, MED was lower for the OTC group on POD-0 (p < 0.001), POD-1 (p = 0.03), and POD-3 (p = 0.03). The RATS-OTC approach results in a more rapid decrease in self-reported pain by the patient as well as significantly lower levels of MED.

Fully Dual-Portal Robotic-Assisted Thoracic Surgery (F-DRATS) and Indocyanine Green-Navigated Segmentectomy

Background: In the landscape of thoracic surgery, innovation continually drives progress, offering novel approaches to address complex pathologies while prioritizing patient well-being. Dual-port robotic-assisted thoracic surgery (DRATS) represents a new frontier in this evolution. In this report, we describe our experience with the fully dual-port robotic-assisted thoracic surgery (F-DRATS) approach for segmentectomy with the indocyanine green intersegmental plane identification. Methods: We define as F-DRATS the robotic thoracic surgery performed by two intercostal incisions without rib spreading, using the robotic camera, robotic dissecting instruments, and exclusively robotic staplers. We herein describe our F-DRATS approach in lingulectomy and lymphadenectomy of stations 5, 6, 7, and 10 using the da Vinci Surgical System. Results: The patient’s postoperative course was uneventful with the chest tube removed on the second postoperative day. The final pathological analysis confirmed a low-grade malignant potential adenocarcinoma, with a main diameter of 1.1 cm, at 3 cm from the lung margins. Conclusions: This is the first description in the literature of a F-DRATS lingulectomy with ICG intersegmental plane identification.

Developing novel non-assistant help operation in dual-portal robotic-assisted thoracic surgery (neoDRATS)

ObjectiveTo introduce and evaluate the non-assistant help operation in dual-portal robotic-assisted thoracic surgery (neoDRATS), a novel technique designed to eliminate the need for skilled assistants by using all 4 robotic arms independently during anatomical lung surgery. MethodsPatients were placed in the lateral decubitus position under general anesthesia with single-lung ventilation. The da Vinci Xi Surgical System was used, with specific configurations for right- and left-side operations. The neoDRATS technique used a 4-cm working port and a 1.8-cm secondary port, with detailed guidelines for optimal setup and robotic arm manipulation. ResultsThe neoDRATS approach demonstrated successful surgical outcomes without the need for a skilled assistant. The use of a 0° camera and careful placement of instruments minimized interference within the thoracic cavity. The technique provided smooth operability and minimized postoperative discomfort. Video demonstrations of right and left upper lobectomies are provided to illustrate the approach. ConclusionsNeoDRATS offers a practical, safe, and minimally invasive alternative to conventional multiportal and uniportal robotic-assisted thoracic surgeries. This technique simplifies the surgical process, particularly in settings with limited availability of skilled assistants, and represents a significant advancement in robotic thoracic surgery. Further refinement and clinical integration of neoDRATS are anticipated as robotic innovations continue to evolve.

Incidence of air leaks in patients undergoing robotic thoracic surgery and video-assisted thoracic surgery.

Postoperative air leakage is the most common complication in surgery for malignant lung tumors, leading to extended hospital stays and substantial medical expenses. This study aimed to identify the incidence and characteristics of intraoperative and postoperative air leaks in both robotic-assisted thoracic surgery (RATS) and video-assisted thoracic surgery (VATS), as well as the causes of persistent air leakage following RATS. We conducted a retrospective analysis of patients who underwent lung resection for malignant lung tumors at our institution from October 2018 to August 2022. We compared the incidence rates of intraoperative air leak, postoperative air leak, and persistent air leak between patients who underwent RATS and those who underwent VATS. Background factors were adjusted using propensity score matching. A subanalysis was performed to compare unexpected air leaks, defined as air leaks not observed intraoperatively but confirmed postoperatively. The study included 295 cases of RATS and 227 cases of VATS. In both the overall population and the matched group (187 cases each for RATS and VATS), RATS demonstrated a significantly higher incidence of persistent air leaks compared to VATS (11% vs 3%, p < 0.01; 9% vs 3%, p = 0.02, respectively). RATS also had a significantly higher incidence of unexpected air leaks compared with VATS (29% vs 18%, p = 0.05). Although there was no statistically significant difference in hospital stays, RATS showed a higher incidence of postoperative persistent air leaks and unexpected postoperative air leaks than VATS.

Greater ipsilateral rectus muscle atrophy after robotic thoracic surgery compared with open and video-assisted thoracoscopic surgery approaches

ObjectiveRobotic thoracic surgery provides another minimally invasive approach in addition to video-assisted thoracoscopic surgery (VATS) that yields less pain and faster recovery compared with open surgery. However, robotic incisions are generally placed more inferiorly, which may increase the risk of intercostal nerve injury that affects the abdominal wall. We hypothesized that a robotic approach causes greater ipsilateral rectus muscle atrophy compared with open and VATS approaches. MethodsThe cross-sectional area and density of bilateral rectus abdominis muscles were measured on computed tomography scans in patients who underwent lobectomy in 2018. The differences between the contralateral and ipsilateral muscles were compared between preoperative and 6-month surveillance scans. Changes were compared among the open, VATS, and robotic approaches through a mixed effects model after adjustments of correlation and covariates. ResultsOf 99 lobectomies, 25 (25.3%) were open, 56 (56.6%) VATS, and 18 (18.1%) robotic. The difference between the contralateral and ipsilateral rectus muscle cross-sectional area was significantly larger at 6 months after robotic surgery compared with open (31.4% vs 9.5%, P = .049) and VATS (31.4% vs 14.1%, P = .021). There were no significant differences in the cross-sectional area between the open and VATS approach. ConclusionsIn this retrospective analysis, there was greater ipsilateral rectus muscle atrophy associated with robotic thoracic surgery compared with open or VATS approaches. These findings should be correlated with clinical symptoms and followed to assess for resolution or persistence.

Loco-Regional Anesthesia for Pain Management in Robotic Thoracic Surgery.

Robotic thoracic surgery is a prominent minimally invasive approach for the treatment of various thoracic diseases. While this technique offers numerous benefits including reduced blood loss, shorter hospital stays, and less postoperative pain, effective pain management remains crucial to enhance recovery and minimize complications. This review focuses on the application of various loco-regional anesthesia techniques in robotic thoracic surgery, particularly emphasizing their role in pain management. Techniques such as local infiltration anesthesia (LIA), thoracic epidural anesthesia (TEA), paravertebral block (PVB), intercostal nerve block (INB), and erector spinae plane block (ESPB) are explored in detail regarding their methodologies, benefits, and potential limitations. The review also discusses the imperative of integrating these anesthesia methods with robotic surgery to optimize patient outcomes. The findings suggest that while each technique has unique advantages, the choice of anesthesia should be tailored to the patient's clinical status, the complexity of the surgery, and the specific requirements of robotic thoracic procedures. The review concludes that a multimodal analgesia strategy, potentially incorporating several of these techniques, may offer the most effective approach for managing perioperative pain in robotic thoracic surgery. Future directions include refining these techniques through technological advancements like ultrasound guidance and exploring the long-term impacts of loco-regional anesthesia on patient recovery and surgical outcomes in the context of robotic thoracic surgery.

Robotic thoracic surgery for neurogenic tumors.

Thoracic neurogenic tumors usually present as benign nerve sheath tumors that can be resected via transthoracic or posterior approaches, depending on the anatomical location. Robot-assisted thoracic surgery (RATS) is increasingly being used for the transthoracic approach, but evidence is very limited. The authors initiated the current study to evaluate the efficacy and safety of RATS for thoracic neurogenic tumors. This retrospective study is based on a prospectively created database that includes all RATS surgeries between 2018 and 2023. All patients with histologically confirmed neurogenic tumors were included in the study. The patients' medical and surgical records as well as radiological and pathological findings were analyzed. During a 5-year period, 27 patients underwent robotic resection of neurogenic tumors at a high-volume thoracic surgery center. Two patients had previously undergone posterior laminectomy for resection of the intraspinal components. The pathologies included schwannomas (18, 64%), ganglioneuromas (8, 29%), 1 paraganglioma, and 1 neurofibroma occurring close to a schwannoma unilaterally in the same patient. The median tumor size was 4.7 cm (range 0.9-11.4 cm). The median operating time was 69 minutes (range 27-169 minutes), and the median postoperative stay was 3 days (range 1-19 days). There was one conversion due to adhesions after a previous surgery. No major bleeding occurred. There was no perioperative mortality. Morbidity included a lymphatic fistula (n = 1), pneumonia (n = 1), prolonged air leak (n = 1), and 4 cases of postoperative pain persisting for more than 4 weeks. Neurological complications were mostly observed in patients with tumors located at the thoracic apex: 2 cases of Horner's syndrome, 2 cases with compensatory hyperhidrosis, 1 patient with paresis of the recurrent laryngeal nerve, and a T1 lesion resulting in a minor motor deficit of the small hand muscles (Medical Research Council grade 4) and hypoesthesia of the respective dermatome. RATS for thoracic neurogenic tumors is feasible and safe. Tumors at the thoracic apex are at high risk of neurological deficit and should be approached with care. Close interdisciplinary collaboration between neurosurgeons and thoracic surgeons is necessary for optimal patient selection and a good postoperative outcome.

Robotic thoracic surgery using the single-port robotic system: Initial experience with more than 100 cases.

This study aimed to report the initial experiences of 115 patients who underwent robotic thoracic surgery using the da Vinci single-port robotic surgical system (Intuitive Surgical). Robotic thoracic surgery using the da Vinci single-port robotic surgical system was performed on 115 patients between November 2020 and June 2023. Patient characteristics, intraoperative outcomes, and postoperative outcomes were analyzed retrospectively. The type of surgeries included thymectomy, mediastinal mass excision, anatomical pulmonary resection (including lobectomy and segmentectomy), esophagectomy, and enucleation of esophageal submucosal tumors in 41, 13, 54, 5, and 2 patients, respectively. The mean total operative time and chest tube duration for different procedures were as follows: thymectomy, 152.9. ± 6.7minutes and 1.2±0.5days; mediastinal mass excision, 93.3±26.5minutes and 1.0±0days; anatomical pulmonary resection, 187.2±55.8minutes and 2.5±1.5days; esophagectomy, 485±111.9minutes and 12±4.6days; and enucleation of esophageal submucosal tumors, 170±30minutes and 5.5±0.5days, respectively. Conversion to a thoracotomy or sternotomy was not required. Conversion to video-assisted thoracic surgery occurred in 1 patient, and an additional port was applied in 2 patients. Two patients experienced postoperative complications greater than grade IIIa. Robotic thoracic surgery using the da Vinci single-port robotic surgical system is feasible and safe in various fields of thoracic surgery, including complex procedures such as anatomical pulmonary resection and esophagectomy. More complex thoracic surgeries can be performed with the continuous advancement and innovation of instruments in robotic systems.

Results of an exploratory survey within ESTS membership in 2022 on current trend of robotic-assisted thoracic surgery and its training perspectives.

Robotic-assisted thoracic surgery (RATS) is increasingly used in our specialty. We surveyed European Society of Thoracic Surgeons membership with the objective to determine current status of robotic thoracic surgery practice including training perspectives. A survey of 17 questions was rolled out with 1 surgeon per unit responses considered as acceptable. A total of 174 responses were obtained; 56% (97) were board-certified thoracic surgeons; 28% (49) were unit heads. Most responses came from Italy (20); 22% (38) had no robot in their institutions, 31% (54) had limited access and only 17% (30) had full access including proctoring. Da Vinci Xi was the commonest system in 56% (96) centres, 25% (41) of them had dual console in all systems, whereas RATS simulator was available only in half (51.18% or 87). Video-assisted thoracic surgery (VATS) was the most commonly adopted surgical approach in 81% of centres (139), followed by thoracotomy in 67% (115) and RATS in 36% (62); 39% spent their training time on robotic simulator for training, 51% on robotic wet/dry lab, which being no significantly different to 46-59% who had training on VATS platform. There was indeed huge overlap between simulator models or varieties usage; 52% (90) reported of robotic surgery not a part of training curriculum with no plans to introduce it in future. Overall, 51.5% (89) responded of VATS experience being helpful in robotic training in view of familiarity with minimally invasive surgery anatomical views and dissection; 71% (124) reported that future thoracic surgeons should be proficient in both VATS and RATS. Half of the respondents found no difference in earlier chest drain removal with either approach (90), 35% (60) reported no difference in postoperative pain and 49% (84) found no difference in hospital stay; 52% (90) observed better lymph node harvest by RATS. Survey concluded on a positive response with at least 71% (123) surgeons recommending to adopt robotics in future.

Completely portal robotic lobectomy in lung cancer: is subcostal specimen removal necessary?

Background The best place for specimen extraction is a relevant question since either after robotic or video-thoracoscopic lobectomy, both intercostal and subcostal routes can be potential extraction routes. In this study, we studied completely portal robotic lobectomies (CPRL-4) for pulmonary neoplasms to investigate the efficacy and feasibility of subcostal specimen removal by comparing the two techniques. Material and Methods Between January 2014 and July 2021, data from 90 patients who underwent robotic thoracic surgery with a Da Vinci Surgical System SI (Intuitive Surgical Inc., Mountain View, California, USA) were collected and retrospectively analyzed. Out of 90 patients, we analyzed 36 CPRL-4 cases. We removed specimens traditionally via intercostal utility thoracotomy in the first 22 patients (group A) and via subcostal incision in the next consecutive 14 patients (group B). Operative parameters, postoperative parameters, the visual analog scale (VAS) and SF36 life quality scoring were comparatively analyzed. Results The mean docking time was significantly higher in group B than in group A (26.2 ± 5.3 vs 17.8 ± 4.1) (p = .001). In terms of early-stage postoperative pain, group B had significantly lower pain scores compared to group A (p < .05). There was no significant difference between the groups in terms of SF36 life quality scoring. Conclusion We can conclude that performing a subcostal incision is not a sophisticated process, though it significantly prolongs the docking time. Although our study is based on a small group, we noticed that removing the specimen through the subcostal incision after CPRL-4 is potentially useful, has several advantages and it is a practical, feasible, and safe method.

Robotic thoracic surgery: lessons learned from the first 1,000 procedures.

The aim of this study was to evaluate the impact of the thoracic robotic approach in a high-volume center regarding procedures and clinical outcomes after 1,000 procedures. In a single-center subset of the Epithor® database, a prospective cohort database of French thoracic surgery, we analyzed procedural characteristics and clinical outcomes from February 2014 to April 2023. A surgical technique for lung surgery was conducted with a four-arm closed chest with the port access approach and vascular sewing and knotting were preferred over stapling. Statistical analysis was performed using the Chi-2 test for discontinuous variables and the Mann-Whitney-Wilcoxon test for continuous variables. Tests were considered significant for a p-value <0.05. Robotic thoracic surgery was used in anatomical lung resection in 85% of the cases. Over the study period, 1,067 patients underwent robotic surgery, of which 509 had lobectomies and 391 segmentectomies. In the segmentectomy group vs. lobectomy group we observed a shorter length of stay (9 ± 7 vs. 7 ± 5.6 days, p < 0.001), a shorter surgery time (99 ± 24 vs. 116 ± 38 min, p < 0.001) a lower conversion rate (n = 2 vs. n = 17, p = 0.004), and a lower complication rate (28% vs. 40%, p = 0.009, mainly Clavien-Dindo II, 18% and 28%, respectively). For cancer treatment surgery, we found more previous cancer in the segmentectomy group (48% vs. 26%, p < 0.001). We also observed a progressive change of lobectomy vs. segmentectomy from 80%/20% to 30%/70% over the 9 years. A robotic platform is an appropriate tool to perform anatomical lung resection and especially to develop a safe and systematic approach to lung-sparing sub-lobar resection.

Initial experience with robotic technology for thoracic surgery using the da Vinci Xi system in Tibet, China.

Although the robotic surgical system has accumulated rich experience in the development of thoracic surgery, its application in Tibet area is relatively late. We report our experience concerning da Vinci Xi system in thoracic surgery and observe its practicability and surgical effect. We retrospectively analyzed 26 patients who underwent robotic thoracic surgery including: twelve lung resection, two esophagectomies, ten mediastinal surgeries and two rib mass resection. The data of patient characteristics, operative time, perioperative complications were collected. Of the 26 patients, 22 cases were completed with da Vinci system successfully, including 7 segmentectomies, 4 lobectomies, 1 subsegmentectomy, 2 esophagectomies, 10 mediastinal surgeries (6 thymic resections, 3 posterior mediastinal tumor resection, 1 mediastinal cyst resection) and 2 rib mass resection. In which, 3 cases of lung resection begun with robotic technique were converted to thoracoscopic surgery (due to calcification of hilar lymph node), 1 case of bilobectomy was converted to thoracotomy due to thoracic adhesion. All the operations went well and no patients need blood transfusion. All patients had satisfactory postoperative recovery. It is safe, reliable and effective to carry out robotic thoracic surgery on the plateau. On the premise of carefully and seriously discussing the indications of surgery, we should actively carry out the application of da Vinci robotic surgery system in Tibet Plateau.

Robot-Assisted Thoracoscopic Resection of Ectopic Parathyroid Tissue in Mediastinum: A Scoping Review.

Ectopic parathyroid tissue in the mediastinum represents a rare and potentially serious clinical entity with challenging diagnostic and surgical management. The main surgical approach for this issue is open thoracotomy, which is a safe technique but carries risks and complications associated with such as extensive surgery. The purpose of this study is to demonstrate robotic thoracic surgery as an alternative and potentially advantageous method to treat patients with ectopic parathyroid adenomas compared with open and video-assisted thoracoscopic surgery approaches. A total of 13 reports in the literature were identified that provided details in terms of complications, surgical approach, and results of minimally invasive surgical resection of mediastinal ectopic parathyroid tissue.

Starting a robotic thoracic surgery program: From wedge resection to sleeve lobectomy in six months. Initial conclusions

IntroductionRobot-assisted thoracic surgery (RATS) is a rapidly expanding technique. In our study, we aimed to analyze the results of the process to adopt robotic surgery in our Department of Thoracic Surgery. MethodsThis is an intention-to-treat analysis of a series of consecutive patients operated on using the RATS approach in our hospital from January 2021 to March 2022. Data were registered for patient characteristics, type of surgery, operative times, conversion rate, chest tube duration, length of hospital stay and complications.The IBM SPSS® statistical software was used for the statistical analysis. A cumulative sum analysis of the operating time was performed to define the learning curve. ResultsDuring the study period, 51 patients underwent robotic surgery, including pulmonary and non-pulmonary interventions. In addition, 15 patients (29.4%) underwent non-pulmonary interventions: one pleural (2%), 2 diaphragmatic (3.9%), and 12 mediastinal (23.5%). Among the mediastinal surgeries, one conversion was necessary (8.3%) for a complex vascular malformation, and 11 were completed by RATS, including 7 (58.3%) thymomas, 3 (25%) pleuro-pericardial cysts, and one (8.3%) neurogenic tumor. Mean operative time was 141 min (104–178), mean chest tube duration was 0.9 days (0–2), and mean length of stay was 1.45 days (1–2).Thirty-six patients underwent lung surgery (70.6%). The complete RATS resections (34; 94.4%) included: 3 wedge resections (11.1%), 2 segmentectomies (3.7%), 28 lobectomies (81.5%), and one sleeve lobectomy (3.7%). Mean surgery time was 194.56 min (141–247), chest tube duration was 3.92 days (1–8), and length of stay was 4.6 days (1–8). Complications occurred in 4 patients (11.1%). No 90-day mortalities were registered. ConclusionsThe implementation of RATS was achieved with good clinical results and operative times for all indications. A rapid learning curve was accomplished in short time. Previous VATS experience, patient selection, team training and program continuity are fundamental to successfully develop a RATS program.

A novel imaging technology to assess tissue oxygen saturation and its correlation with indocyanine green in the gastric conduit during thoracic esophagectomy

BackgroundAnastomotic leakage in esophagectomy is a serious complication, and assessing blood perfusion in the conduit can help minimize this risk. Indocyanine green is the most widely used method to assess tissue blood flow; however, this technique has disadvantages. Evaluating tissue oxygen saturation in the gastric conduit during thoracic esophagectomy compared with indocyanine green blood perfusion assessment addresses these disadvantages and can be performed easily and repeatedly. MethodsThis was a prospective study of patients with esophageal cancer who underwent thoracic esophagectomy. Intraoperative tissue oxygen saturation and indocyanine green measurements were obtained to determine the anastomotic site and to compare the correlation between the 2 methods. Tissue oxygen saturation and indocyanine green values were obtained at the tip of the gastric conduit, the demarcation line indicating visible perfusion, and the end of the right gastroepiploic artery. ResultsFifty-seven patients were enrolled in this study; 3 developed anastomotic leakage, and all 3 underwent robotic thoracic surgery. The tissue oxygen saturation value decreased gradually toward the tip of the conduit, as did congestion, and was significantly decreased at the tip compared with the value at the demarcation line (P = .001). Mean tissue oxygen saturation differed significantly between the leakage and no-leakage groups at the anastomosis site (P = .04). We found a negative correlation between tissue oxygen saturation and indocyanine green values at the end of the right gastroepiploic artery (r = −0.361; P = .03). ConclusionTissue oxygen saturation imaging was useful in determining the anastomotic site and addressed the disadvantages associated with indocyanine green.

Uniportal pure robotic-assisted thoracic surgery-technical aspects, tips and tricks.

The uniportal access for robotic thoracic surgery presents itself as a natural evolution of minimally invasive thoracic surgery (MITS). It was developed by surgeons who pioneered the uniportal video-assisted thoracic surgery (U-VATS) in all its aspects following the same principles of a single incision by using robotic technology. The robotic surgery was initially started as a hybrid procedure with the use of thoracoscopic staplers by the assistant. However, due to the evolution of robotic modern platforms, the staplers can be nowadays controlled by the main surgeon from the console. The pure uniportal robotic-assisted thoracic surgery (U-RATS) is defined as the robotic thoracic surgery performed through a single intercostal (ic) incision, without rib spreading, using the robotic camera, robotic dissecting instruments and robotic staplers. There are presented the advantages, difficulties, the general aspects and specific considerations for U-RATS. For safety reasons, the authors recommend the transition from multiportal-RATS through biportal-RATS to U-RATS. The use of robotic dissection and staplers through a single incision and the rapid undocking with easy emergent conversion when needed (either to U-VATS or to thoracotomy) are safety advantages over multi-port RATS that cannot be overlooked, offering great comfort to the surgeon and quick and smooth recovery to the patient.
