ObjectiveTo compare the perioperative efficacy and safety of robot-assisted thoracoscopic surgery (RATS) and uniportal video-assisted thoracoscopic surgery (UVATS) in the lobectomy for early lung adenocarcinoma.MethodsClinical data of 70 early lung adenocarcinoma patients, receiving RATS or UVATS lobectomy by the same surgical team in our hospital from November 2018 to May 2020 were retrospectively analyzed. There were 24 males and 46 females with an average age of 59.3±8.9 years. According to different surgical methods, the patients were divided into a RATS group (31 patients) and a UVATS group (39 patients). The operation time, intraoperative blood loss, postoperative hospital stay, indwelling time, drainage volume, number of lymph node dissected, stations of lymph node dissected and perioperative complications were compared between the two groups.ResultsThere was no conversion to thoracotomy or perioperative death in both groups. There was no significant difference in intraoperative blood loss, postoperative hospital stay, indwelling time of thoracic drainage tube, thoracic drainage volume or stations of lymph node dissected between the two groups (P>0.05). There was no significant difference in the incidence of pulmonary infection, persistent lung leakage, chylothorax, arrhythmia or overall complications between the two groups (P>0.05). The operation time of the RATS group was longer than that of the UVATS group (195.8±52.8 min vs. 154.0±43.1 min, P=0.001). The number of lymph node dissected in the RATS group was more than that of the UVATS group (P=0.016).ConclusionBoth RATS and UVATS are safe and feasible in the treatment of lung cancer. The number of lymph nodes removed by RATS is significantly more than that of UVATS.
Objective To compare the safety and efficacy of the subxiphoid robot-assisted thoracoscopic surgery (SRATS) and intercostal robot-assisted thoracoscopic surgery (IRATS) for the treatment of anterior mediastinal tumors. Methods The clinical data of patients who received robot-assisted anterior mediastinal tumor resection in the same medical unit of the Department of Thoracic Surgery of Gansu Provincial Hospital from May 2020 to July 2022 were retrospectively collected. The patients were divided into a SRATS group and an IRATS group according to the surgical procedure. The perioperative data of patients were compared between the two groups. Results Finally 87 patients were collected, including 41 in the SRATS group (23 males and 18 females, mean age of 44.51±11.28 years) and 46 in the IRATS group (21 males and 25 females, mean age of 46.67±8.76 years). All 87 patients completed the surgery successfully. Compared with IRATS group, SRATS group had less intraoperative blood loss (24.41±6.67 mL vs. 37.93±9.23 mL, P=0.000), shorter postoperative catheterization time (1.73±0.59 d vs. 2.54±0.50 d, P=0.000), less postoperative drainage (94.46±34.08 mL vs. 116.72±24.90 mL, P=0.001), lower visual analogue score (VAS) on the first postoperative day (3.66±0.76 points vs. 4.15±0.84 points, P=0.005) and third postoperative day (2.41±0.59 points vs. 2.89±0.82 points, P=0.003), shorter postoperative hospital stay (4.12±0.81 d vs. 4.98±1.02 d, P=0.000) and lower hospitalization costs (45.1±6.5 thousand yuan vs. 48.6±6.8 thousand yuan, P=0.020). There was no significant difference in the operation time or the incidence of postoperative complications. Conclusion Both SRATS and IRATS have high safety and efficacy in the treatment of anterior mediastinal tumors. However, SRATS has less damage, which is more conducive to the rapid recovery of patients after surgery, and has a wide prospect of clinical application.
Objective To compare the safety and efficacy of the da Vinci robot and thoracoscopic subxiphoid approach for the treatment of anterior mediastinal tumors. Methods The clinical data of patients who underwent anterior mediastinal tumor resection through the subxiphoid approach admitted to the same medical group in the Department of Thoracic Surgery of the First Hospital of Lanzhou University between June 2020 and April 2022 were retrospectively analyzed. According to the surgery approach, the patients were divided into a robot-assisted thoracoscopic surgery (RATS) group and a video-assisted thoracoscopic surgery (VATS) group. The perioperative data and the incidence of postoperative complications were compared between the two groups. ResultsA total of 79 patients were enrolled. There were 41 patients in the RATS group, including 13 males and 28 females, with an average age of 45.61±14.99 years. There were 38 patients in the VATS group, including 14 males and 24 females, with an average age of 47.84±15.05 years. All patients completed the surgery successfully. Hospitalization cost and operative time were higher or longer in the RATS group than those in the VATS group, and the difference was statistically significant (P<0.05). Intraoperative bleeding, postoperative hospital stay, postoperative water and food intake time, postoperative off-bed activity time, white blood cell count, neutrophil percentage and visual analogue scale (VAS) score on the first postoperative day, white blood cell count and neutrophil percentage on the third postoperative day, duration of analgesic pump use, the number of voluntary compressions of the analgesic pump, and mediastinal drainage volume were all superior to those in the VATS group (P<0.05). The differences in VAS scores on the third postoperative day, duration of drainage tube retention and postoperative complication rates were not statistically different between the two groups (P>0.05). Conclusion RATS subxiphoid anterior mediastinum tumor resection is a safe and feasible surgical method with less injury and higher safety, which is conducive to rapid postoperative recovery and has wide clinical application prospects.
ObjectiveTo evaluate the short-term outcome of robot-assisted thoracoscopic surgery (RATS) for the treatment of posterior mediastinal neurogenic tumour. MethodsThe clinical data of consecutive patients with mediastinal neurogenic tumors who received RATS treatment completed by the same operator in the Department of Thoracic Surgery, Gansu Provincial People's Hospital from June 2016 to June 2022 were retrospectively analyzed. The tumors were preoperatively localized and evaluated using magnetic resonance imaging or enhanced CT. Results A total of 35 patients were enrolled, including 19 males and 16 females with a mean age of 34.9±7.1 years. All patients successfully completed the resection of posterior mediastinal neurogenic tumors under RATS, and no conversion to thoracotomy occurred during the operation. The average operative time was 62.3±18.0 min, docking time was 10.3±2.6 min, intraoperative bleeding was 33.9±21.6 mL, postoperative 24-hour chest drainage was 69.0±28.9 mL, postoperative chest drainage time was 2.0 (1.0, 3.0) d and the postoperative hospital stay was 3.0 (2.0, 4.0) d. Postoperative complications occurred in 3 patients, including 2 patients with transient Honor syndrome and 1 patient with transient anhidrosis of the affected upper limb. ConclusionRATS for posterior mediastinal neurogenic tumours is safe, effective and feasible, and allows the full benefit of the robotic surgical system to be exploited.
ObjectiveTo systematically evaluate of the difference in clinical outcomes between Da-Vinci robot-assisted thoracoscopic surgery (RATS) and video-assisted thoracoscopic surgery (VATS) for mediastinal tumor resection. MethodsOnline databases including The Cochrane Library, PubMed, EMbase, Web of Science, SinoMed, CNKI, and Wanfang were searched by two researchers independently from inception to October 10, 2022. The quality of the included literature was evaluated using the Newcastle-Ottawa Scale (NOS). The meta-analysis was performed by RevMan 5.3. ResultsA total of 23 studies with 5 646 patients were enrolled in the final study. The NOS scores of the studies were≥6 points. The results of meta-analysis showed that compared with the VATS group, the blood loss was less [MD=−18.11, 95%CI (−26.12, −10.09), P＜0.001], time of postoperative drainage tube retention [MD=−0.79, 95%CI (−1.09, −0.49), P＜0.001] and postoperative hospitalization time [MD=−1.00, 95%CI (−1.36, −0.64), P＜0.001] were shorter, postoperative day 1 drainage [MD=−5.53, 95%CI (−9.94, −1.12), P=0.010] and total postoperative drainage [MD=−88.41, 95%CI (−140.85, −35.97), P=0.001] were less, the rates of postoperative complications [OR=0.66, 95%CI (0.46, 0.94), P=0.020] and conversion to thoracotomy [OR=0.32, 95%CI (0.19, 0.53), P＜0.001] were lower, and the hospitalization costs were higher [MD=2.60, 95%CI (1.40, 3.79), P＜0.001] in the RATS group. The operative time was not statistically different between the two groups [MD=5.94, 95%CI (−1.45, 13.34), P=0.120]. ConclusionRATS mediastinal tumor resection has a high safety profile. Compared with VATS, patients have less intraoperative blood loss, a lower rate of conversion to thoracotomy, and shorter postoperative tube time and hospital stay, which is more conducive to rapid postoperative recovery.
