New Insurance Product Needed for Physicians: Coverage for Sham Peer Review and Hospital Immunity.

This commentary article highlights the need for an insurance product for hospital-employed physicians that provides coverage against sham peer review and a complete defense against wrongful hospital allegations of incompetent, whistleblowing, or disruptive behavior.

Development of the fundamentals of thoracic robotic surgery curriculum.

A great technological revolution in surgery occurred with the introduction of laparoscopic and other minimally invasive procedures, with enormous patient benefits. Robotic-assisted surgery (RAS) is a form of minimally invasive surgery that overcomes some of the limitations of laparoscopic techniques. Until recently, there were few standardized curricula for RAS. The Fundamentals of Robotic (FRS) developed a process through expert consensus conferences to develop an effective and validated curriculum for basic robotic surgery. A specialty specific curriculum for thoracic robotic surgery is also needed. The Fundamentals of Thoracic Robotic Surgery (FTRS) Consensus Conference brought together expert thoracic surgeons to build upon the accomplishments of FRS and incorporate the experiences of thoracic societies and academic institutions to establish a standardized FTRS curriculum for the development and maintenance of specialty-specific robotic surgical skills. A task deconstruction was completed for the thoracic 'signature' procedure, the lobectomy and training items and potential errors were identified for each step of the procedure. A final outline of the FTRS curriculum was developed during the conference and physical and virtual reality thoracic surgery training models were discussed. Following the conference, the steering committee completed the FTRS curriculum with editorial review from all stakeholders. The FTRS consensus conference followed the validated FRS model but in an accelerated process due to important groundwork set by experts in the FRS consensus conferences. A full online curriculum and supporting psychomotor skills training and team communication has been developed for the lobectomy procedure.

Robotic first rib resection for thoracic outlet syndrome.

Robotic resection of the "offending portion" of the first rib in patients with thoracic outlet syndrome (TOS) has been associated with excellent results. The results have been due to (I) a better understanding of the pathogenesis of TOS, and (II) the technical advantages of the robotic platform. This article outlines the recent understanding of the pathogenesis of TOS, and reports the experience with robotic resection of the "offending portion" of the first rib in patients with neurogenic and venous TOS. Patients diagnosed with TOS underwent robotic first rib resection. Diagnosis of TOS was made by magnetic resonance angiography (MRA). On a thoracoscopic platform, the robot was used to dissect the "offending portion" of the first rib. A total of 162 patients underwent robotic first rib resection. Eighty-three patients underwent robotic first rib resection for Paget-Schroetter syndrome (PSS) (venous TOS). There were 49 men and 34 women. Mean age was 24±8.5 years. Operative time was 127.6±20.8 minutes. Median hospitalization was 4 days. There were no surgical complications, neurovascular injuries, or mortality. At a median follow-up of 24 months, all patients had an open subclavian vein (SV) for a patency rate of 100%. Seventy-nine patients underwent robotic first rib resection for neurologic symptoms of the upper extremity (neurogenic TOS). There were 29 men and 50 women. Mean age was 34±9.5 years. Operative time was 87.6±10.8 minutes. There were no intraoperative complications. Hospital stay ranged from 2-4 days with a median hospitalization of 3 days. There were no neurovascular complications. There was no mortality. In patients with neurogenic symptoms, Quick DASH Scores (mean ± SEM) decreased from 60.3±2.1 preoperatively to 5±2.3 in the immediate postoperative period, and 3.5±1.1 at 6 months (P<0.0001). Immediate relief of symptoms was seen in 71/79 (91%) patients. Persistent paresthesia was seen in 9/79 (9%) immediately postop and 3/79 (3.8%) patients at 6 months. Following the appropriate identification of the "offending portion" of the first rib which results in compression of the SV at its junction with the innominate vein by MRA, robotic resection of the "offending portion" of the first rib allows is associated with excellent results.

Society of Robotic Surgery review: recommendations regarding the risk of COVID-19 transmission during minimally invasive surgery.

OBJECTIVES: To determine the risk of COVID-19 transmission during minimally invasive surgical (MIS) procedures METHODS: Surgical society statements regarding the risk of COVID transmission during MIS procedures were reviewed. In addition, the available literature on COVID-19 and other viral transmission in CO2 pneumoperitoneum, as well as the presence of virus in the plume created by electrocautery during MIS was reviewed. The society recommendations were compared to the available literature on the topic to create our review and recommendations to mitigate COVID-19 transmission. RESULTS: The recommendations promulgated by various surgical societies evolved over time as more information became available on COVID-19 transmission. Review of the available literature on the presence of COVID-19 in CO2 pneumoperitoneum was inconclusive. There is no clear evidence of the presence of COVID-19 in plume created by electrocautery. Technologies to reduce CO2 pneumoperitoneum release into the operating room as well as filter viral particles are available and should reduce the exposure risk to operating room personnel. CONCLUSION: There is no clear evidence of COVID-19 virus in the CO2 used during MIS procedures or in the plume created by electrocautery. Until the presence or absence of COVID-19 viral particles has been clearly established, measures to mitigate CO2 and surgical cautery plume release into the operating room should be performed. Further study on the presence of COVID-19 in MIS pneumoperitoneum and cautery plume is needed.

Robotic Staged Bilateral Selective Postganglionic Sympathectomy for Upper-Extremity Hyperhidrosis.

PURPOSE: The prevalence of compensatory hyperhidrosis (CH) has been reported to be as high as 80% in patients following thoracic sympathectomy for upper-extremity hyperhidrosis. The CH rate is 7.2% with simultaneous bilateral robotic selective dorsal sympathectomy. We reviewed the results in patients who underwent staged bilateral robotic selective dorsal sympathectomy (SBRSS). METHODS: A case series analysis of patients who underwent SBRSS was performed. A surgical robot was used to divide the postganglionic sympathetic fibers and communicating rami to intercostal nerves 2, 3, and 4. The sympathetic chain was left intact. The operation was performed on the dominant side, and the same procedure was then performed on the contralateral side after 4 weeks. The success of the sympathectomy was determined by intraoperative temperature measurement, patient interviews, and the Hyperhidrosis Disease Severity Scale. RESULTS: There were 47 patients (22 men, 25 women), with a mean age of 22 ± 3 years. Minor complications were seen in 4% of patients. One patient had transient heart block. One patient had transient partial Horner's syndrome. Forty percent of patients had transient CH after the first surgery, and 45% had transient CH after sympathectomy on the contralateral side. There were no deaths. The median hospitalization was 3 days. At a mean follow-up of 28 ± 6 months, 46/47 patients (98%) had sustained relief of hyperhidrosis. In one patient (1/47, 2%), hyperhidrosis recurred on the first operated side. One patient (2%) exhibited sustained CH. CONCLUSION: SBRSS is associated with a lower rate of CH than when the procedure is performed bilaterally in a simultaneous fashion. This procedure is associated with the lowest reported rate of CH.

Robotic Lobectomy: Experience with 638 Consecutive Cases.

BACKGROUND: Robotic lobectomy has been evolving over the past decade and has been shown to be an oncologically acceptable procedure. We evaluated our experience with robotic lobectomy for the treatment of early-stage lung cancer. METHODS: We performed a retrospective review of prospectively accrued patients at our institution who underwent robotic lobectomy for early-stage lung cancer from February 2004 to July 2019, RESULTS: Of 3304 consecutive patients who underwent a robotic operation by a single surgeon, 638 underwent robotic lobectomy for early-stage primary non-small cell lung cancer (NSCLC; stages I and II). The 427 (67%) men and 211 (33%) women had a median age of 69 y (range 41-86), and 567 (89 %) were former or current smokers. The median operative time was 176 minutes (range 160-456), the median chest tube time was 3 days (2-8), the median air leak time was 0 days (0-3), and the median length of stay was 3 days (1-26). The median tumor size was 2.6 cm (range 06-3.4). The mean number of nodes recovered was 14 ± 3. Pathologic upstaging was noted in 121 patients (19%). Minor complications were observed in 133 patients (21%). Conversion to thoracotomy occurred in 11 (1.7%) patients. Mortality was 0.5%. CONCLUSION: Robotic lobectomy is a safe, minimally invasive procedure that replicates the oncologic and technical principles of thoracotomy for the treatment of lung cancer.

Robotic First Rib Resection for Thoracic Outlet Syndrome.

PURPOSE: First rib resection is a key component of the treatment of Thoracic Outlet Syndrome (TOS). We report our experience with, and technique for, robotic first rib resection. METHODS: Patients diagnosed with TOS underwent robotic first rib resection of the offending portion of the first rib with disarticulation of the costo-sternal joint. Definitive diagnosis of TOS was made by Magnetic Resonance Angiography (MRA) with maneuvers. RESULTS: A total of 67 patients underwent robotic first rib resection. Neurogenic TOS: 39 patients underwent robotic resection for Neurologic Symptoms of the upper extremity (Neurogenic TOS). There were 14 men and 25 women, with a mean age of 34 ± 9.5 years. Paget-Schroetter Syndrome (PSS) or Venous TOS: 28 patients underwent transthoracic robotic first rib resection for PSS. There were 16 men and 12 women, with a mean age of 24 ± 8.5 years. Operative time was 87.6 ± 10.8 minutes. There were no intraoperative complications. Hospital stay ranged from 2 to 4 days with a median hospitalization of 3 days. There were no neurovascular complications. There was no mortality. In patients with Neurogenic TOS, QuickDASH Scores (mean ± SEM) decreased from 60.3 ± 2.1 preoperatively to 5 ± 2.3 in the immediate postoperative period and to 3.5 ± 1.1 at 6 months (p<0001). Immediate relief of symptoms was seen in 35/39 patients (91%). Persistent paresthesia was seen in 4/39 (9%) immediately postop, and in 2/39 (2.5%) at 6 months. Thirty-seven of 39 (97.5%) patients reported complete relief of symptoms. Among patients with PSS or Venous TOS, 9/28 (32%) required endovascular venoplasty to completely open the subclavian vein after the relief of extrinsic compression. At a median follow-up of 24 months, all patients with PSS had an open subclavian vein, for a patency rate of 100%. CONCLUSIONS: Robotic transthoracic first rib resection allows for minimally invasive resection of the first rib in patients with TOS, with excellent relief of symptoms and no neurovascular complications.

Robotic transthoracic first-rib resection for Paget-Schroetter syndrome.

OBJECTIVES: First-rib resection is a key component in the treatment of Paget-Schroetter syndrome. We report our experience with robotic first-rib resection. METHODS: Patients diagnosed with Paget-schroetter syndrome underwent thrombolysis followed by robotic first-rib resection. The diagnosis was made by preoperative venography (VA) and magnetic resonance venography. The robot was used to dissect the first rib, disarticulate the costosternal joint and divide the scalene muscles. Success of the first-rib resection was assessed by physical examination, venogram and magnetic resonance venography. RESULTS: Eighty-three robotic first-rib resections were performed (49 men and 34 women). The mean age of the patients was 24 years ± 8.5 years. The operative time was 127.6 min ± 20.8 min. The median hospitalization was 4 days. There were no surgical complications, neurovascular injuries or mortality. Patients with a patent subclavian vein on the postoperative venogram (57 of 83 patients, 69%) were anticoagulated with warfarin for 3 months. In the remaining 27 patients with a persistent postoperative occlusion of the subclavian vein, 21 (21 of 83 patients, 24%) underwent angioplasty and were anticoagulated with warfarin for 3 months, and 6 (6 of 83, 7%) required stent placement to achieve complete vein patency. Patients who underwent stent placement received antiplatelet therapy in addition to warfarin anticoagulation for 3 months. At a median follow-up of 24 months, all patients had an open subclavian vein with a patency rate of 100%. CONCLUSIONS: The robotic transthoracic first-rib resection is feasible and allows for a minimally invasive resection of the first rib, while minimizing neurovascular complications.

Long-term Results of Robotic Modified Belsey (Gastroesophageal Valvuloplasty) Fundoplication.

PURPOSE: Nissen fundoplication is associated with poor long-term durability, as well as dysphasia and gas bloat. We report here the long-term results of modified Belsey fundoplication (Gastroesophageal Valvuloplasty; GEV) performed laparoscopically using a surgical robot. METHODS: Patients who underwent robotic GEV were reviewed retrospectively. Operations were performed by laparoscopy and included robotic dissection of the esophageal hiatus, primary closure of the hiatus, followed by intussusception of a 4 cm segment of the esophagus into the stomach for 270°, and suspension of the fundoplication on the hiatal closure. The results were assessed by postoperative endoscopy, contrast esophagography, a Subjective Symptom Questionnaire (SSQ), and objective Visick grading. RESULTS: There were 291 patients (156 male, 135 female, mean age 51±14 years). Indications were intractability (73%) and pulmonary symptoms (27%). Mean operative time was 130 minutes ± 52 minutes. Minor complications were seen in 21%. There was no mortality. Mean hospitalization was 2.8 days ± 1.7 days. Mean follow-up was 85 months ± 7 months. During this period, the mean SSQ score decreased from 8.3 ± 0.6 to 0.7± 0.2 (P < 0.05). There was no long-term dysphasia or gas bloat. Ninety-five percent of patients were Visick I and 5% were Visick II. Hiatal hernia recurred in 7 patients (2%). CONCLUSIONS: Robotic laparoscopic modified Belsey fundoplication (GEV) is associated with excellent long-term durability, reflux control, and low rates of dysphasia and gas bloat. This procedure may represent an alternative to medical antireflux therapy and other surgical antireflux procedures such as Nissen fundoplication.

Long-term results of robotic anatomical segmentectomy for early-stage non-small-cell lung cancer.

OBJECTIVES: Anatomical segmentectomy is advocated for curative resection in select patients. We investigated the long-term results of robotic anatomical segmentectomy with mediastinal nodal dissection in patients with early-stage lung cancer. METHODS: We retrospectively reviewed patients who underwent robotic anatomical segmentectomy for early-stage non-small-cell lung cancer (NSCLC). The follow-up data were obtained to determine survival and statistically significant risk factors in both univariable and multivariable models. RESULTS: Seventy-one patients had clinical stage I NSCLC (36 men, 35 women, mean age 70 ± 12 years). All patients underwent R0 resection. The mean operating time was 134 min. Ten of 71 (14%) patients were upstaged. Eight of 71 (11%) patients were upstaged due to the size of tumour in the pathological specimen, and 2 of 71 (3%) patients were upstaged due to microscopic N2 nodal metastasis. Median hospitalization was 4 days (2-31 days). Complication rate was 29%. There were no complications attributable to the surgical robot. No patient died within 90 days. Mean follow-up was 54 months (range 2 months to 9 years). The overall 5-year survival was 43%, whereas lung cancer-specific 5-year survival was 55%. The 5-year lung cancer-specific survival for pathological stage I disease was 73%. Local or mediastinal recurrence occurred in 4 of 71(5%) patients. Pathological upstaging or recurrence resulted in 0% 5-year survival. The univariable and multivariable analyses showed that advanced age and pathological upstaging were statistically significant risk factors for lung cancer-specific death. CONCLUSIONS: Robotic anatomical segmentectomy with mediastinal nodal dissection is a safe and feasible procedure. Accurate preoperative clinical staging is of critical importance for long-term survival.

Unilateral robotic hybrid mini-maze: a novel experimental approach.

BACKGROUND: A complete Cox maze IV procedure is difficult to accomplish using current endoscopic and minimally invasive techniques. These techniques are hampered by inability to adequately dissect the posterior structures of the heart and place all necessary lesions. We present a novel approach, using robotic technology, that achieves placement of all the lesions of the complete maze procedure. METHODS: In three cadaveric human models, the technical feasibility of using robotic instruments through the right chest to dissect the posterior structures of the heart and place all Cox maze lesions was performed. RESULTS: The entire posterior aspect of the heart was dissected in the cadaveric model facilitating successful placement of all Cox maze IV lesions with robotic assistance through minimally invasive incisions. CONCLUSION: The robotic Cox maze IV procedure through the novel right thoracic approach is feasible. This obviates the need for sternotomy and avoids the associated morbidity of the conventional Cox-maze procedure.

Robotic resection of a superior sulcus neurogenic tumor.

Neurogenic tumors do not often occur in the superior sulcus or apex of the chest cavity. Historically, surgical approaches have been dictated by the location of the tumor and its relation to the contiguous structures such as the vertebral bodies, subclavian vessels, and chest wall. Resection is hampered by difficulties with visualization and access within a narrow working space. The shortcomings associated with the traditional surgical approaches create a potential of injury to nearby structures. We present a case of a 43-year-old woman with a superior sulcus neurogenic tumor impinging on the left subclavian vein, who underwent a successful resection without injury to nearby structures. We found that a robotic approach improved visualization of the tumor and nearby structures and increased instrument maneuverability relative to a thoracoscopic approach, along with less pain and recovery time compared with a thoracotomy. This experience suggests that robotics provides a promising alternative for excision of superior sulcus neurogenic tumors, which may reduce associated morbidity.

Tissue-type plasminogen activator-induced fibrinolysis is enhanced in patients with breast, lung, pancreas and colon cancer.

Although cancer-mediated changes in hemostatic proteins unquestionably promote hypercoagulation, the effects of neoplasia on fibrinolysis in the circulation are less well defined. The goals of the present investigation were to determine if plasma obtained from patients with breast, lung, pancreas and colon cancer was less or more susceptible to lysis by tissue-type plasminogen activator (tPA) compared to plasma obtained from normal individuals. Archived plasma obtained from patients with breast (n = 18), colon/pancreas (n = 27) or lung (n = 19) was compared to normal individual plasma (n = 30) using a thrombelastographic assay that assessed fibrinolytic vulnerability to exogenously added tPA. Plasma samples were activated with tissue factor/celite, had tPA added, and had data collected until clot lysis occurred. Additional, similar samples had potato carboxypeptidase inhibitor added to assess the role played by thrombin-activatable fibrinolysis inhibitor in cancer-modulated fibrinolysis. Rather than inflicting a hypofibrinolytic state, the three groups of cancers demonstrated increased vulnerability to tPA (e.g. decreased time to lysis, increased speed of lysis, decreased clot lysis time). However, hypercoagulation manifested as increased speed of clot formation and strength compensated for enhanced fibrinolytic vulnerability, resulting in a clot residence time that was not different from normal individual thrombi. In sum, enhanced hypercoagulability associated with cancer was in part diminished by enhanced fibrinolytic vulnerability to tPA.

Thoracic tumor effects on plasmatic coagulation: role of hemeoxygenase-1.

OBJECTIVES: Lung cancer is an important health threat worldwide, and is associated with a 3.8-13.9% incidence of thrombophilia. Of interest, patients with lung tumors have been noted to have an increase in endogenous carbon monoxide production via upregulation of hemeoxygenase-1 activity. Given that it has been demonstrated that carbon monoxide enhances plasmatic coagulation in vitro and in vivo via formation of carboxyhemefibrinogen, we sought to determine if patients with thoracic tumors undergoing lung resection/pneumonectomy had an increase in endogenous carbon monoxide and concurrent plasmatic hypercoagulability. MATERIALS AND METHODS: Nonsmoking patients with thoracic tumors (n=19) had preoperative carboxyhemoglobin (a measure of carbon monoxide production) determined, and a thromboelastometric method to assess citrated plasma coagulation kinetics and the formation of carboxyhemefibrinogen was utilized. Thoracic tumor patient coagulation kinetics was compared with normal subject (n=30) plasma samples. RESULTS AND CONCLUSION: Patients with thoracic tumors were determined to have an abnormally increased carboxyhemoglobin concentration of 2.1±0.6%, indicative of hemeoxygenase-1 upregulation. It was found that 84% of thoracic tumor patients had plasma clot strength that exceeded the 95% confidence interval value observed in normal subjects, and 44% of this hypercoagulable subgroup had carboxyhemefibrinogen formation. Future investigation of the role played by plasmatic hypercoagulability and hemeoxygenase-1 derived carboxyhemefibrinogen in the pathogenesis of thoracic tumor related thrombophilia is warranted.

Selective sympathectomy for hyperhidrosis: technique of robotic transthoracic selective postganglionic efferent sympathectomy.

Selective postganglionic efferent sympathectomy for hyperhidrosis is associated with excellent relief of hyperhidrosis and a low rate of compensatory hyperhidrosis. However, this technique can be difficult using conventional videoendoscopic techniques. We performed this technique using robotic technology in 55 patients. There was complete relief of hyperhidrosis in 53/55 (96%) patients, partial relief in 2/55 (4%) patients and a compensatory hyperhidrosis rate of 7%.

Robotic selective postganglionic thoracic sympathectomy for the treatment of hyperhidrosis.

BACKGROUND: The surgical management of hyperhidrosis is controversial. Robotic surgical systems with their high-definition magnified 3-dimensional view and increased maneuverability in a confined space may facilitate the technique of selective sympathectomy (ramicotomy). We present a case series of patients undergoing selective postganglionic thoracic sympathectomy using robotic technology. METHODS: This study is a case series analysis of patients who underwent selective postganglionic thoracic sympathectomy from July 2006 to November 2011. The operation was performed on a video-assisted thoracoscopic surgery (VATS) platform. The robot was used for pleural dissection and division of the postganglionic sympathetic fibers and the communicating rami. The success of sympathectomy was assessed by intraoperative temperature measurement of the ipsilateral upper extremity, patient interviews, and scoring of the symptomatic nature of hyperhidrosis based on the Hyperhidrosis Disease Severity Scale. RESULTS: There were 110 sympathectomies performed in 55 patients (25 men, 30 women). Simultaneous bilateral sympathectomy was performed in all patients. Median age was 28 years (range, 16 to 65 years). There was no conversion to thoracotomy. Complications were minor and were seen in 5 of 55 patients (9%). There were no deaths. Median hospital stay was 1 day (range, 1 to 4 days). Of the 55 patients, 53 (96%) had sustained relief of their hyperhidrosis at a median follow-up of 24 months (range, 3 to 36 months), and compensatory sweating was seen in 4 patients (7.2%). CONCLUSIONS: Robotic thoracoscopic selective sympathectomy is an effective, feasible, and safe procedure with excellent relief of hyperhidrosis and low rates of compensatory sweating and complications.

The learning curve of robotic lobectomy.

BACKGROUND: Robotic lobectomy has been shown to be feasible, safe and oncologically efficacious. The actual learning curve of robotic lobectomy has yet to be defined. This study was designed to define the learning curve of robotic lobectomy. METHODS: We performed a retrospective review of prospectively accrued patients at our institution who underwent robotic lobectomy from January 2004 until December 2011. Six scatter graphs were constructed, comparing operative time, conversion rate, morbidity, mortality, length of stay and surgeon comfort with the number of consecutive cases. In each graph, a regression trendline was drawn and the change in the slope of the curve corresponding to the beginning of the plateau defined the learning curve. The overall learning curve was defined as mean ± SD of the sum of the individual learning curves. RESULTS: Based on operative times, mortality and surgeon comfort, the overall learning curve was 18 ± 3 cases. The learning curve based on operative times, mortality and surgeon comfort was 15, 20 and 19 cases, respectively. There was no association between the need for conversion and number of consecutive cases. There was a trend towards lower morbidity and decreased length of stay with greater experience. However, these parameters did not define a specific learning curve. CONCLUSIONS: Operative time, mortality and surgeon comfort were found to be key parameters for the learning curve of robotic lobectomy when performed by surgeons who are experienced with video-assisted thoracic surgery (VATS). The learning curve was 18 ± 3 cases.

Robotic-assisted treatment of celiac artery compression syndrome: report of a case and review of the literature.

BACKGROUND: The surgical management of celiac artery compression syndrome (CACS) is controversial. Controversies include the appropriate surgical technique, the surgical approach, and the utility of postoperative stents. The literature is reviewed, and a case of CACS is presented in which a robotic-assisted division of the median arcuate ligament (MAL) was performed. METHODS: Robotic-assisted treatment of celiac artery syndrome was carried out using six (five 1 cm and one 2 cm) abdominal incisions. The robotic device was used to expose the aorta and celiac artery and divide the median arcuate ligament. RESULTS: Postoperatively, the patient's postprandial abdominal pain subsided. On 16 month follow-up, the patient was doing well, tolerated an unrestricted diet without symptoms, and exhibited weight gain. CONCLUSION: This case is the second reported in the literature and demonstrates that the robotic approach to division of the MAL is feasible, safe, and efficacious.

Robotic en bloc first-rib resection for Paget-Schroetter disease, a form of thoracic outlet syndrome: technique and initial results.

OBJECTIVE: First-rib resection is a key component of the treatment of Paget-Schroetter disease. There are many controversies regarding the management of this disease. We report a safe, effective, minimally invasive robotic transthoracic approach for resection of the first rib. METHODS: Over an 8-month period, five patients underwent robotic first-rib resection. Preoperative assessment included physical examination and bilateral venous angiography. On a thoracoscopic platform using three 2-cm incisions and one 1-cm incision, the robot was used to dissect the first rib and divide the scalene muscles. Success of the first-rib resection was assessed by postoperative venous angiography. RESULTS: There were four men and one woman. Mean age was 34.6 ± 10 years. Mean operative time was 195 ± 24.6 minutes. There were no complications and no mortality. All patients had a patent subclavian vein on the postoperative venogram and were anticoagulated with warfarin for 3 months. At a median follow-up of 12 months, all patients had an open subclavian vein for a patency rate of 100%. CONCLUSIONS: Robotic thoracoscopic first-rib resection represents a feasible minimally invasive approach to en bloc resection of the first rib. This technique minimizes the risk of neurovascular complications that are associated with conventional techniques.
