ObjectiveTo investigate the effectiveness of sublobar resection and lobectomy via uniportal video-assisted thoracoscopic surgery (U-VATS) for lung metastases from colorectal cancer.MethodsRetrospective research was conducted on 42 colorectal cancer patients with lung metastases who underwent U-VATS sublobar resection and lobectomy at the Tongji Hospital, Huazhong University of Science and Technology between April 2016 and May 2019, including 24 males and 18 females with an average age of 58.0±9.9 years. Among them 17 patients received U-VATS sublobar resection and 25 patients received lobectomy. The operation time, intraoperative blood loss, postoperative pulmonary infection, drainage tube indwelling time, drainage volume on the first day after surgery, postoperative hospital stay were analyzed between the two groups, and the relationship between the prognosis and clinical characteristics of the two groups was compared.ResultsSublobar resection patients had less lung metastases (P=0.043) and shorter operation time (P=0.023) compared with the lobectomy patients. There was no significant difference between the lobectomy and sublobar resection groups in intraoperative blood loss (P=0.169), rate of postoperative infection (P=0.982), postoperative drainage duration (P=0.265), drainage volume on the first day after surgery (P=0.402) and postoperative hospital stay (P=0.612). The progression-free survival of the two groups was 25.19 months and 23.63 months (P=0.721), and their overall survival was 29.09 months and 30.64 months (P=0.554).ConclusionConsidering guantity and locations of lung metastases, U-VATS sublobar resection can achieve a similar prognosis to lobectomy for lung metastases from colorectal cancer. Further efficacy of this surgical strategy remains to be proved by longer follow-up.
ObjectiveTo compare the effect on postoperative immune function between da Vinci robot-assisted thoracoscopic surgery (RATS) and video-assisted thoracoscopic surgery (VATS) , and to provide clinical support for more effective surgical procedures.MethodsA total of 90 patients undergoing radical resection of pulmonary carcinoma in our hospital from June to November 2019 were included. There were 49 males and 41 females with an average age of 62.67 (37-84) years. Among them, 50 patients underwent da Vinci robot-assisted thoracoscopic surgery (a RATS group) and 40 patients underwent video-assisted thoracoscopic surgery (a VATS group). The perioperative indexes as well as postoperative inflammatory factors and immune level effects between the two groups were compared.ResultsCompared with the VATS, RATS could significantly shorten the operation time and decrease intraoperative blood loss (P<0.05). RATS also effectively reduced the increase of postoperative inflammatory factor level (P<0.05). But there was no significant difference in postoperative immune function between the RATS group and the VATS group (P>0.05).ConclusionRATS is superior to VATS in the treatment of non-small cell lung cancer in perioperative indicators and inflammatory factors.
ObjectiveTo investigate the feasibility and clinical effect of controlled hypotension in 3 cm single-port video-assisted thoracoscopic surgery (VATS) for the lymph node group 7 dissection in the left lung resection. MethodsWe retrospectively analyzed the clinical data of 37 patients with lung cancer who underwent 3 cm single-port VATS from May 2015 to August 2015 in Tongji Hospital, and systolic blood pressure of 12 patients (7 males, 5 females, average age of 58.3 years, range 42-69 years) was controlled between 80-90 mm Hg by nitroglycerin or sodium nitroprusside while the pressure of 25 patients (14 males, 11 females, average age of 57.7 years, range 43-68 years) was not controlled when receiving lymph node group 7 dissection. ResultsControlled hypotension in lymphadenectomy achieved satisfactory results. The lymphadenectomy time of 12 patients with controlled hypotension (18.5±4.3 min on average, range 15.6-25.3 min) was shorter than that of 25 patients without controlled hypotension (24.3±5.1 min on average, range 18.2-29.8 min); the difference was statistically significant (P<0.05). ConclusionControlled hypotension is a simple and feasible method that increases the operating space, and reduces the difficulty of cleaning lymph nodes and the risk of bleeding.
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 evaluate the short-term outcomes and hospital costs of robot-assisted thoracic surgery (RATS) versus video-assisted thoracoscopic surgery (VATS) for non-small cell lung cancer. MethodsThe clinical data of patients who underwent lobectomy or sublobar resection for non-small cell lung cancer completed by the same operator in the Department of Thoracic Surgery, Gansu Provincial Hospital from June 2016 to June 2022 were retrospectively analyzed. According to the surgery approach, the patients were divided into a RATS group and a VATS group. The clinical data of the two groups were compared. ResultsA total of 516 patients were enrolled. There were 254 patients in the RATS group, including 103 males and 151 females, with a mean age of 60.0±4.2 years, and 262 patients in the VATS group, including 126 males and 136 females, with a mean age of 59.5±4.3 years. All patients in both groups successfully completed radical lung cancer surgery with no perioperative death. In terms of intraoperative bleeding (63.4±13.3 mL vs. 92.5±23.5 mL), postoperative drainage time (4.1±0.9 d vs. 4.7±1.2 d), postoperative hospital stay time (5.6±1.1 d vs. 6.7±1.4 d), number of lymph nodes dissected (17.9±2.1 vs. 13.9±1.4) and groups of lymph nodes dissected (5.4±0.8 groups vs. 4.4±1.0 groups), the RATS group had an advantage, and the difference was statistically significant (P<0.05). In terms of operative time and total postoperative chest drainage, the VATS group had an advantage, and the difference was statistically significant (P<0.05). There was no statistical difference between the two groups in terms of postoperative complications or intraoperative conversion to thoractomy (P>0.05). The total hospitalization, surgical and total consumables costs of the RATS group were higher than those in the VATS group (P<0.05). In terms of other costs and consumables costs (one-time costs of purely high-value consumables after deduction of robot-specific costs), the VATS group was higher than the RATS group (P<0.05). ConclusionRATS offers technical and short-term efficacy advantages, but comes with the disadvantage of high costs. Thoracic surgeons can make full use of the features of the robotic surgery system, exploiting its potential to continuously improve and optimize techniques and reduce the use of high-value consumables, thus achieving efficiency and cost reductions and allowing robotic surgery to reach more patients.
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.
ObjectiveTo evaluate the feasibility and clinical effect of controlled hypotension in video-assisted thoracoscopic surgery (VATS) for subcarinal lymph node dissection in patients with lung cancer.MethodsWe analyzed the clinical data of 53 non-small cell lung cancer (NSCLC) patients undergoing VATS with controlled systolic blood pressure while dissecting the subcarinal lymph node from September to October 2016 in our department (a treatment group, including 31 males and 22 females with an average age of 53.20±8.80 years ranging 43-68 years). We selected 112 NSCLC patients undergoing VATS without controlled systolic blood pressure while dissecting the subcarinal lymph node from January to August 2016 in our department (a contol group, including 67 males and 45 females with an average age of 54.32±7.81 years ranging 39-73 years). The clinical data of both groups were compared.ResultsThe operation time and blood loss of the treatment group were less than those of the control group (177.6±39.4 min vs. 194.3±47.8 min, 317.9±33.6 ml vs. 331.2±38.7 ml, P<0.05). The duration of subcarinal lymph node dissection and total duration of lymph node dissection of the treatment group were also less than those of the control group (10.5±4.3 min vs. 13.6±5.2 min, 37.7±7.5 min vs. 48.7±6.4 min, P<0.001). The thoracic drainage at postoperative days 1, 2, 3 and total drainage volume, duration of tube placement and hospital stay of the treatment group were less than those of the control group (P<0.05). Whereas the postoperative complications of the two groups did not differ significantly (P>0.05).ConclusionControlled hypotension reduces the difficulty of dissecting subcarinal lymph nodes and the risk of bleeding, and produces less drainage volume, which is safe and effective.
Objective To investigate the advantage of the concept of wide exposure in uniportal video-assisted thoracoscopic surgery (uniportal-VATS) for radical resection of lung cancer and assess its safety and feasibility. Methods Clinical data of 255 patients (110 males and 145 females, a mean age of 54.3±7.9 years) with non-small cell lung cancer (NSCLC) who received wide exposure in uniportal-VATS or three portal VATS (3P-VATS) during August 2017 to March 2018 were retrospectively analyzed. There were 153 patients (67 males and 86 females, a mean age of 56.1±8.5 years) in the uniportal-VATS group and 102 patients (43 males and 59 femals, a mean age of 54.4±7.4 years) in the 3P-VATS group. The clinical effects were compared between the two groups. Results There was no statistical difference in the operation time between the uniportal-VATS and 3P-VATS (135.0±45.6 min vs. 142.0±39.5 min, P>0.05). The overall number of dissected stations (6.9±1.0) and LNs (14.5±3.0) in the uniportal-VATS group were similar with those in the 3P-VATS group (7.1±1.0, 15.1±1.7). The dissected stations of N2 LNs (uniportal-VATS: 4.1±1.7, 3P-VATS: 3.9±0.8) and number of dissected N2 LNs (uniportal-VATS: 8.0±0.9, 3P-VATS: 7.8±1.1) were both similar between the two groups. The duration of postoperative tube drainage and postoperative hospital stay of uniportal-VATS group (3.5±1.8 d and 7.2±0.9 d) were much shorter than those of 3P-VATS group (4.0±1.3 d and 8.8±2.0 d). No significant difference was found in incidence of postoperative complication between the two groups except that the incidence of subcutaneous emphysema in the uniportal-VATS group was much lower. There was no perioperative death in the two groups. Conclusion The concept of wide exposure in uniportal-VATS can meet the requirment of radical resection and it is a safe and valid method which can be used for radical resection of lung cancer.
Minimally invasive surgery (MIS) is currently mainly used for the treatment of early thymic tumors. In recent years, minimally invasive thymic surgery has been rapidly promoted at home and abroad. However, because of the low incidence of thymic tumors, the unbalanced experience of doctors, there are still many issues worthy of discussion in MIS. Standard MIS must follow similar oncological and resection principles. This paper involves the definitions of minimally invasive thymic surgery and general principles that should be adhered to when performing MIS for thymic malignances.
Objective To explore the safety, feasibility and learning curve of video-assisted thoracoscopic surgery(VATS) in treatment of thoracic diseases. Method We retrospectively analyzed the clinical data of 591 patients of thoracic surgery in our hospital between September 2009 and September 2016. There were 378 males and 213 females at age of 14–82 years. Result All patients were successfully completed surgery. Twelve patients converted to open chest with conversion rate of 2.0%. Postoperative complications occurred in 24 patients (4.1%). Four patients died during the perioperative period, and mortality rate was 0.7%. The learning curve of VATS for lung cancer was about 25 patients. And the learning curve of video-assisted laparoscopy for resection of esophageal cancer was about 15 patients. Conclusion VATS is safety and feasible for the chest disease patients in municipal hospital, and is worthy to popularize.
