Objectives: Surgery through a single port may be less painful because access is supplied by 1 intercostal nerve or more painful because multiple instruments are used in 1 port. We analyzed data collected from the video-assisted thoracoscopic surgery group of a randomized controlled trial to compare differences in pain up to 1 year. Methods: Groups were compared in a prespecified exploratory analysis using direct (regression) and indirect comparison (difference with respect to thoracotomy). In-hospital visual analogue scale pain scores were used, and analgesic ratios were calculated. After discharge, pain was evaluated using European Organization for Research and Treatment of Cancer Quality of Life Questionnaires-Core 30 scores up to 1 year. Results: From July 2015 to February 2019, we randomized 503 participants. After excluding 50 participants who did not receive lobectomy, surgery was performed using a single port in 42 participants (predominately by a single surgeon), multiple ports in 166 participants, and thoracotomy in 245 participants. No differences were observed in-hospital between single- and multiple-port video-assisted thoracoscopic surgery when modeled using a direct comparison, mean difference of −0.24 (95% CI, −1.06 to 0.58) or indirect comparison, mean difference of −0.33 (−1.16 to 0.51). Mean analgesic ratio (single/multiple port) was 0.75 (0.64 to 0.87) for direct comparison and 0.90 (0.64 to 1.25) for indirect comparison. After discharge, pain for single-port video-assisted thoracoscopic surgery was lower than for multiple-port video-assisted thoracoscopic surgery (first 3 months), and corresponding physical function was higher up to 12 months. Conclusions: There were no consistent differences for in-hospital pain when lobectomy was undertaken using 1 or multiple ports. However, better pain scores and physical function were observed for single-port surgery after discharge.

Background: Innovations in surgical instruments have made single-port surgery more widely accepted and lead to a reduced demand for surgical assistants. As COVID-19 has ravaged the world, maintaining minimum medical staffing requirements and proper social distancing have become major topics of interest. We sought to evaluate the feasibility of applying the unisurgeon approach in single-port video-assisted thoracoscopic surgery aided by a robotic camera holder. Methods: Operative time, blood loss, setup time, postoperative hospital stays, and the number of participating surgeons in single-port video-assisted thoracoscopic lung resections were gathered for investigation after the introduction of the ENDOFIXexo robotic endoscope holder system. In this cohort, we collected 213 patients who underwent single port video thoracoscope surgery, including 57 patients underwent robotic endoscope arm assisted surgery and case-matched 52 patients in the robotic arm–assisted group with patients in the human-assisted group through propensity score–matched analysis. Results: In wedge resection, a single surgeon was able to completely operate on all lobes of target lesions. However, for anatomical resections, namely segmentectomy, the success rate was 95%, and for lobectomy, the success rate was only 64%. No significant differences between setup times, blood loss, or operative times between the two groups were observed. Conclusions: When an experienced uniport surgeon is assisted by a robotic endoscope holder, wedge resection is the most suitable procedure to be performed through unisurgeon single-port video-assisted thoracoscopic surgery without increasing setup time, operative time, or short-term complications. Verification of the technique's applicability for use in anatomic resections requires further investigation. [ABSTRACT FROM AUTHOR]

Abstract Background Pulmonary metastasectomy was performed in the early twentieth century and ever since, it has evolved to be one of the main treatment options for certain metastatic malignancies. The advancement of minimally invasive procedures enabled new techniques to minimize morbidity and improve patient quality of care and overall outcome. Cases presentation Herein we present three patients, aged 53, 48, and 27 years, known to have sigmoid, rectal, and non-seminomatous germ cell tumors respectively. All patients were diagnosed to have metastatic lung nodules and underwent laparotomy to excise abdominal tumors followed by trans-diaphragmatic single-port video-assisted thoracoscopic pulmonary metastasectomy. All patients achieved complete surgical tumor excision, and none had pulmonary related complications on follow-up. Conclusion Our prescribed novel trans-diaphragmatic single-port video-assisted thoracoscopic surgery (VATS) technique for synchronous pulmonary metastasectomy and intra-abdominal tumor resection is safe and can achieve complete resection with negative margins.

Background: Our objective is to report on two centers' experience of intra-operative management of major vascular injury during single-port video-assisted thoracoscopic (SPVATS) anatomic resections, including bleeding control techniques, incidence, results, and risk factor analysis.Methods: Consecutive patients (n = 442) who received SPVATS anatomic lung resections in two centers were enrolled. The different clinical parameters studied included age, previous thoracic surgery, obesity (BMI > 30), tumor location, neoadjuvant therapy, and pleural symphysis. In addition, peri-operative outcomes were compared between the groups, with or without vessel injury.Results: There were no intra-operative deaths in our study. Overall major bleeding incidence was 4.5%, whereby 70% of major bleeding episodes could be managed with SPVATS techniques. In order to determine risk factors possibly related to intra-operative bleeding, we used case control matching to homogenize our study population. After case control matching, pleural symphysis was significantly related in the univariate (p = 0.005, Odds ratio 4.415, 95% CI 1.424-13.685) and multivariate analysis (p = 0.006, Odds ratio 4.926, 95% CI 1.577-15.384). Operative time (p < 0.001), blood loss (p < 0.001), and post-operative hospital stay (p = 0.012) were longer in patients with major vascular injury. There were no differences in 30-day mortality and 90-day morbidity.Conclusions: In summary, major intra-operative bleeding episodes during SPVATS anatomic lung resections are acceptable and most such bleeding episodes can be safely managed with SPVATS techniques.

Minimally invasive, safe and tumor-free are the main principles of the choice of surgical incision in lung cancer surgery. In recent years, with the advances in minimally invasive techniques, single-port video assisted thoracic surgery (VATS), robot-assisted thoracoscopic (RATS), suboxiphoid single-port VATS, simultaneous bilateral VATS pulmonary resection, are emerging approaches, single-port VATS has become one of the most exciting new developments in minimally invasive thoracic surgery in recent years. This paper reviews the evolution and trends of surgical incision in lung cancer surgery.
