ObjectiveTo evaluate the feasibility and clinical value of robot-assisted lobectomy through anterior approach.MethodsWe retrospectively analyzed the clinical data of 180 patients who underwent robot-assisted lobectomy through anterior approach in our hospital between April 2017 and February 2018. There were 97 males and 83 females, aged 59.5 (32.0-83.0) years. The clinical effects were analyzed.ResultsOne patient was transferred to thoracotomy due to tumor invasion of adjacent blood vessels and injury to the blood vessels, and there was no perioperative death. There were 8.5 (1.0-35.0) dissected lymph nodes for each patient. The median operation time was 120 (50-360) min, including robot Docking time 5 (1-23) min and robot operation time 65 (7-270) min. The median blood loss was 50 (5-1 500) mL, 132 (73.3%) patients had malignant tumors and median drainage time was 5 (2-30) d. The mean postoperative pain score was 3.4±0.7 points and the postoperative hospital time was 8 (2-32) d. At the median follow-up of 24 months, 11 patients developed recurrence and metastasis, and 3 died.ConclusionRobot-assisted lobectomy through anterior approach is a safe and convenient operation method, which is worthy of clinical application.
Surgery has remained the cornerstone of lung cancer therapy. Sleeve lobectomy, which is featured by not only the maximal resection of tumors but also the maximal preservation of functional lung parenchyma, has been proved to be a valid therapeutic option for the treatment of some centrally located lung cancer . Evidence points toward equivalent oncologic outcomes with improved survival and quality of life after sleeve resections compared with pneumonectomy. However, the postoperative morbidities and the long-term results after sleeve lobectomy remain controversial, especially in relation to nodal involvement and after induction therapy. With the development of technology, minimally invasive procedures have been performed more and more widely.
Objective To explore the feasibility of 5G remote robot-assisted pulmonary lobectomy through animal experiments. Methods In this research, the Toumai® surgical robot was manipulated remotely by the surgeon in the Control Center of the MedBot Company through the 5G network established by China Telecom, and the experimental pig underwent lobectomy in simulated operating room. Results The animal experiment surgery was successfully completed. The surgeon remotely manipulated the surgical robot to complete the lobectomy of right apical lobe and mediastinal lymph node dissection. The entire animal experiment took about 60 minutes, with an average round-trip network delay of 125 (110-155) ms, and no network interruption or robot malfunction occurred. Conclusion This animal experiment is the first attempt of 5G remote thoracic surgery, which preliminarily proves the feasibility of completing remote lobectomy through the Toumai® surgical robot 5G wireless network connection. The systematic surgical procedure is summarized, which lays a foundation for the subsequent experiments and clinical applications of 5G remote robot-assisted thoracic surgery.
ObjectiveTo explore the value of the single-direction lobectomy in the treatment of complicated pulmonary tuberculosis.MethodsA retrospective analysis was performed on 88 patients with complicated pulmonary tuberculosis who received lobectomy in our hospital from 2017 to 2019. There were 64 males and 24 females, with an average age of 21-70 (47.67±13.39) years. According to the surgical procedure, patients who received single-direction lobectomy were divided into a single-direction group (n=32), and those who received traditional lobectomy were divided into a control group (n=56).ResultsThe two groups had no statistical differences in gender, age, primary disease and complications, lesion morphology, clinical symptoms, operative site, interlobitis adhesion or hilar mediastinal lymph node calcification (P>0.05). Operation time [210.0 (180.0, 315.0) min vs. 300.0 (240.0, 320.0) min], intraoperative blood loss [200.0 (100.0, 337.5) mL vs. 325.0 (200.0, 600.0) mL], postoperative lung air leak time [3.0 (2.0, 5.0) d vs. 9.0 (6.8, 12.0) d] and the postoperative hospital stay [11.5 (8.0, 14.8) d vs. 18.0 (14.0, 22.0) d] of the single-direction group were less or shorter than those of the control group (P<0.05). There was no statistical difference between the single-direction group and the control group in the incidence of surgical complications [1 patient (3.12%) vs. 10 patients (17.86%)] or the cure rate [32 patients (100.00%) vs. 54 patients (96.43%)].ConclusionThe single-direction lobectomy can reduce lung injury and bleeding, shorten the duration of operation and accelerate the postoperative recovery in patients with complicated pulmonary tuberculosis, which has certain advantages compared with traditional lobectomy.
Objective To compare the mean operative time and complications between the LigaSure device and Harmonic Scalpel during video-assisted endoscopic approaches thyroidectomy. Methods The clinical data of 684 cases performed Miccoli thyroidectomy by the same operation team from January 2007 to December 2011 in the department of general surgery，Shanghai Sixth People’s Hospital Affiliated to Shanghai Jiao Tong University were analyzed. Three hundred and forty-nine patients were used Harmonic Scalpel，335 patients were used LigaSure device. The mean operative time and complications （such as hematoma，transient hoarseness，permanent recurrent laryngeal nerve injury，and hypocalcemia） were compared between two groups. Results A total of 684 patients were included in the study，of whom 263 underwent total thyroidectomy and 421 underwent lobectomy. There were not significant differences of the operative time and the complications in both thyroidectomy and lobectomy between the LigaSure device and Harmonic Scalpel（P＞0.05）. Conclusions The uses of the LigaSure device and Harmonic Scalpel in thyroid surgery are safe and reliable，surgeons may choose surgical instruments by habits and medical equipments.
ObjectiveTo investigate the effect of multi-sided foramen ultrafine drainage tube with metal support on the formation of thoracic residual cavity after uniportal video-assisted thoracoscopic (VATS) upper lobectomy. MethodsThe clinical data of the patients who underwent uniportal VATS upper lobectomy for lung cancer in the Department of Thoracic Surgery of the First Hospital of Lanzhou University from January 2021 to April 2022 were retrospectively analyzed. According to the type of ultrafine drainage tube used in the surgery, the patients were divided into a test group (using metal-supported multi-sided foramen ultrafine drainage tube) and a control group (using ordinary 12F ultrafine drainage tube). The incidence of postoperative thoracic residual cavity and operation-related data were compared between the two groups. ResultsA total of 200 patients were enrolled, including 126 males and 74 females, with a mean age of 57.52 years. There were 90 patients in the test group, and 110 patients in the control group. The incidence of postoperative thoracic residual cavity in the test group was lower than that in the control group (P=0.045). The differences in the postoperative bedtime, postoperative visual analogue scale, postoperative analgesic pump using time, postoperative hospitalization time, times of postoperative thoracentration and drainage, postoperative drainage time and hospitalization cost between the two groups were statistically significant (P<0.05). The incidences of postoperative lung infection, pleural effusion and atelectasis complications were lower in the test group than those in the control group (P<0.05). The differences in the preoperative anesthesia time, operation time, intraoperative bleeding and postoperative lung leakage were not statistically significant (P>0.05). ConclusionThe use of multi-sided foramen ultrafine drainage tube with metal support can reduce the incidence of thoracic residual cavity after uniportal VATS upper lobectomy, and can reduce pain and economical burdens and the incidence of operation-related complications, accelerating the recovery of patients after surgery. The application of multi-sided foramen ultrafine drainage tube with metal support in uniportal VATS upper lobectomy can be widely used in the clinic.
ObjectiveTo explore the feasibility and short-term efficacy of uniportal and three-port single-direction video-assisted thoracoscopic surgery (S-VATS) anatomical lobectomy for lung cancer.MethodsClinical data of 60 lung cancer patients, including 40 males and 20 females with an average age of 62.2±9.0 years, who received S-VATS anatomic lobectomy and systematic lymph nodes dissection by the same surgeon in our hospital between July 2016 and January 2019 were retrospectively analyzed. These patients were divided into a uniportal S-VATS group and a three-port S-VATS group according to surgical procedures, with 30 patients in each group. The clinical data of the two groups were compared.ResultsThere was no conversion to thoracotomy, surgical port addition, or mortality in this cohort, with tumor-negative surgical margin. There was no statistical difference in the operation time between the two groups (70.8±16.4 min vs. 73.7±14.3 min, P>0.05). Meanwhile, both groups showed similar intraoperative blood loss, stations and numbers of dissected lymph nodes, incidence of operation-related complications, duration and volume of chest tube drainage, as well as postoperative hospital stay (P>0.05). Besides, pain score of the patients in the uniportal S-VATS group was significantly lower than that of the three-port S-VATS group on postoperative 3-14 d (P<0.05). The mean duration of follow-up was 10 months, and all the patients were survived without tumor recurrence or metastasis.ConclusionThe transition from three-port S-VATS to uniportal S-VATS anatomical lobectomy for treatment of lung cancer is feasible. However, further studies are needed to elucidate the optimal resection sequence of pulmonary vessels.
Proper management of chest drainage after pulmonary lobectomy is a topic that every thoracic surgeon must face up to. Reasonable chest drainage plays a critical role in postoperative normal physiological recovery. However， there are still controversies and discrepancies in many aspects of chest drainage management after pulmonary lobectomy. In this review，we focus on five aspects of chest drainage management after pulmonary lobectomy，including the choice of chest drainage system，single or double chest tubes，suction or not，treatment of persistent air leak，and removal of chest tube.
ObjectiveTo investigate the safety and feasibility of thoracoscopic lobectomy without mechanical suture.MethodsThe data of 28 consecutive patients (a non-mechanical suture group, 16 males and 12 females at age of 61.23±11.10 years) who underwent non-mechanical suture anatomic thoracoscopic lobectomy performed by the same surgeon from March 2015 to March 2018 were analyzed retrospectively, and 28 patients (18 males and 10 females at age of 59.45±13.39 years) who underwent completely anatomic thoracoscopic lobectomy with endoscopic stapler (a mechanical suture group) in the same period were matched. The clinical effectiveness of the two groups was compared.ResultsThe operation time between the non-mechanical suture group (136.30±53.46 min) and the mechanical suture group (109.63±44.61 min) showed a statistical difference (P<0.05). While in term of intraoperative bleeding volume (65.00 ml vs. 50.00 ml), postoperative thoracic drainage time (3.73 days vs. 3.56 days), thoracic drainage volume (538.60 ml vs. 563.70 ml), postoperative hospital stay (5.58 days vs. 5.35 days) and postoperative complication rate (5/28 vs. 6/28), there was no statistical difference between the two groups. Hospitalization expense was significantly different between the two groups (35 438.30 yuan vs. 51 693.60 yuan).ConclusionNon-mechanical suture thoracoscopic anatomic lobectomy is safe and feasible, and can significantly reduce the medical cost but prolong the operation time.
ObjectiveTo investigate the effectiveness and safety of robotic lobectomy in clinical N0 lung malignant tumor≥3 cm. MethodsWe retrospectively analyzed the clinical data of 182 patients with lung malignant tumor≥3 cm receiving robotic or thoracoscopic lobectomy at Shanghai Chest Hospital in 2019. The patients were divided into a robotic surgery group (RATS group) and a thoracoscopic surgery group (VATS group). There were 39 males and 38 females with an average age of 60.55±8.59 years in the RATS group, and 51 males and 54 females with an average age of 61.58±9.30 years in the VATS group. A propensity score matching analysis was applied to compare the operative data between the two groups. ResultsA total of 57 patients were included in each group after the propensity score matching analysis. Patients in the RATS group had more groups of N1 lymph node dissected (2.53±0.83 groups vs. 2.07±0.88 groups, P=0.005) in comparison with the VATS group. No statistical difference was found in operation time, blood loss, postoperative hospital stay, number of N1 and N2 lymph nodes dissected, groups of N2 lymph node dissected, lymph node upstage rate or postoperative complications. The hospitalization cost of RATS was higher than that of VATS (P＜0.001). ConclusionIn contrast with thoracoscopic lobectomy, robotic lobectomy has similar operative safety, and a thorough N1 lymphadenectomy in patients with clinical N0 lung malignant tumor≥3 cm.
