ABSTRACT
@#Objective To compare the surgical efficacy of Da-Vinci robot-assisted thoracic surgery (RATS) and video-assisted thoracic surgery (VATS) for non-small cell lung cancer (NSCLC). Methods Online databases including PubMed, EMbase, Web of Science, The Cochrane Library, CNKI, Wanfang, VIP and CBM from inception to 18 February, 2022 were searched by two researchers independently. The references of related studies were also searched to re-enroll the potential studies. The quality of the studies was evaluated with Newcastle-Ottawa Scale (NOS). The meta-analysis was performed by RevMan 5.3. Results A total of 43 studies including 33 089 patients were enrolled in the final study. The NOS scores of the included studies were ≥6 points. The results of meta-analysis showed that the operation time was longer [MD=8.50, 95%CI (1.59, 15.41), P=0.020], the blood loss was less [MD=−46.58, 95%CI (−62.86, −30.29), P<0.001], the dissected lymph nodes stations were more [MD=0.67, 95%CI (0.40, 0.93), P<0.001], the dissected lymph nodes were more [MD=2.39, 95%CI (1.43, 3.36), P<0.001], the conversion rate was lower [OR=0.52, 95%CI (0.46, 0.59), P<0.001], the time of chest tube drainage was shorter [MD=−0.35, 95%CI (−0.58, −0.11), P=0.004], the length of hospital stay was shorter [MD=−0.32, 95%CI (−0.45, −0.19), P<0.001], and the recurrence rate was lower [OR=0.51, 95%CI (0.36, 0.72), P<0.001] in the RATS group than those in the VATS group. The rate of overall postoperative complications [OR=0.95, 95%CI (0.89, 1.01), P=0.110] and postoperative mortality rate [OR=0.85, 95%CI (0.62, 1.16), P=0.300] were not significantly different between the two groups. Conclusion Compared with VATS, although RATS prolongs the operation time, it does not increase the incidence of postoperative complications and mortality rates. Moreover, RATS can dissect more lymph nodes, effectively control intraoperative bleeding, shorten the duration of chest drainage tube indwelling and shorten the postoperative hospital stay to a certain extent.

@#Objective To compare and analyze the therapeutic effects of robot-assisted lobectomy and segmentectomy for stage ⅠA non-small cell lung cancer with a diameter≤2 cm. Methods A total of 181 patients with pathologically confirmed stage ⅠA non-small cell lung cancer (diameter≤2 cm) who underwent robot-assisted lobectomy and segmentectomy in our hospital from 2018 to 2021 were included. There were 74 males and 107 females with an average age of 57.50±10.60 years. They were divided into two groups according to the surgical procedure: a segmentectomy group (85 patients) and a lobectomy group (96 patients). Results There was no statistically significant difference between the two groups in terms of clinical data such as age, gender, smoking history, basic disease, pathological type, tumour diameter, operative time, postoperative 24 h drainage volume and overall complications (P>0.05). The intraoperative blood loss (33.88±16.26 mL vs. 39.27±19.48 mL, P=0.046), groups of dissected lymph nodes (4.76±1.19 vs. 5.52±1.46, P=0.000), number of dissected lymph nodes (14.81±7.23 vs. 18.06±7.70, P=0.004) and postoperative 72 h drainage volume (561.65±225.31 mL vs. 649.84±324.34 mL, P=0.037) of patients in the segmentectomy were less than those in the lobectomy group. The chest drainage time (5.49±3.92 d vs. 7.60±4.96 d, P=0.002) and postoperative hospital stay time (7.47±4.16 d vs. 9.67±5.50 d, P=0.003) were shorter than those in the lobectomy group. There was no conversion to thoracotomy or perioperative death in the two groups. The postoperative follow-up rate was 100.0% with a longest follow-up time of 48 months. The 3-year recurrence-free survival rates of the segmentectomy group and lobectomy group were 87.7% and 92.4%, respectively (P=0.465). Conclusion The da Vinci robot-assisted lobectomy and segmentectomy are safe and feasible surgical procedures for patients with stage ⅠA non-small cell lung cancer (diameter≤2 cm), with a similar 3-year recurrence-free survival rate. The lobectomy group has more lymph nodes dissected, while the segmentectomy group is superior to the lobectomy group in terms of intraoperative blood loss, postoperative 72 h chest drainage volume, chest drainage time and postoperative hospitalization time.
ABSTRACT
@#Objective To investigate the application of enhanced recovery after surgery (ERAS) in da Vinci robotic McKeown surgery for esophageal cancer. Methods Clinical data of patients admitted to the First Hospital of Lanzhou University and undergoing da Vinci robotic McKeown surgery for esophageal cancer from 2017 to 2021 were retrospectively analyzed. According to the treatment, they were divided into two groups, a conventional group and an ERAS group. Patients in the conventional group were treated with the conventional perioperative treatment mode of thoracic surgery, and patients in the ERAS group were treated with accelerated rehabilitation surgical treatment mode. Relevant hospitalization indicators and postoperative complication rates were compared between the two groups. Results Finally 128 patients were collected, including 106 males and 22 females, with an average age of 61.91 years. There were 71 patients in the conventional group and 57 patients in the ERAS group. The postoperative pain index in the ERAS group was significantly lower than that in the conventional group (P<0.05), and the duration of postoperative analgesic pump used in the ERAS group was shorter than that in the conventional group (2.39±0.49 d vs. 3.13±0.63 d, P<0.001). There was no statistical difference in the incidence of postoperative related complications (gastroesophageal reflux, anastomotic stenosis, anastomotic fistula, arrhythmia, recurrent laryngeal nerve injury, chylothorax, anastomosis stomatitis or incisional infection) between the two groups (P>0.05), but the incidence of postoperative lung infection in the ERAS group was statistically lower (12.28% vs. 26.76%, P=0.043), and the volume of postoperative pleural effusion was statistically less compared with the conventional group (P<0.05). In the ERAS group, the surgery time (294.35±15.19 min vs. 322.79±59.09 min, P<0.001), postoperative exhaust time (1.44±0.39 d vs. 1.94±0.43 d, P<0.001), postoperative removal time of nasolasal tube (6.79±0.73 d vs. 8.21±0.86 d, P<0.001), hospital stay (19.88±3.36 d vs. 21.34±3.59 d, P=0.020), hospitalization costs (105 575.28±8 960.75 yuan vs. 137 894.64±19 518.60 yuan, P<0.001) were all lower or shorter than those of the conventional group. Postoperative activity was longer in the ERAS group than that in the conventional group (P<0.05), but there was no statistical difference in preoperative anesthesia time between the two groups (P=0.841). Conclusion The application of ERAS in da Vinci robotic McKeown surgery for esophageal cancer can effectively alleviate the physiological and psychological burden of patients, reduce the occurrence of postoperative related complications, effectively shorten the total hospital stay, save hospitalization costs, and reduce the economic burden of patients and society. Therefore, it can be promoted and applied in the clinic.
ABSTRACT
@# Objective To analyze the risk factors for postoperative length of stay (PLOS) after mediastinal tumor resection by robot-assisted non-endotracheal intubation and to optimize the perioperative process. Methods The clinical data of patients who underwent Da Vinci robot-assisted mediastinal tumor resection with non-endotracheal intubation at the Department of Thoracic Surgery, General Hospital of Northern Theater Command from 2016 to 2019 were retrospectively analyzed. According to the median PLOS, the patients were divided into two groups. The univariate analysis and multivariate logistic regression were used to analyze risk factors for prolonged PLOS (longer than median PLOS). Results A total of 190 patients were enrolled, including 92 males and 98 females with a median age of 51.5 (41.0, 59.0) years. The median PLOS of all patients was 3.0 (2.0, 4.0) d. There were 71 patients in the PLOS>3 d group and 119 patients in the PLOS≤3 d group. Multivariate logistic regression showed that indwelled thoracic catheter [OR=11.852, 95%CI (2.384, 58.912), P=0.003], preoperative symptoms of muscle weakness [OR=4.814, 95%CI (1.337, 17.337), P=0.016] and postoperative visual analogue scale>5 points [OR=6.696, 95%CI (3.033, 14.783), P<0.001] were independent factors for prolonged PLOS. Totally no tube (TNT) allowed patients to be discharged on the first day after surgery. Conclusion Robot-assisted mediastinal tumor resection with non-endotracheal intubation can promote rapid recovery. The methods of optimizing perioperative process are TNT, controlling muscle weakness symptoms and postoperative pain relief.
ABSTRACT
@#Objective To compare the clinical efficacy and safety of da Vinci robot with totally no tube (TNT) versus subxiphoid video-assisted thymectomy surgery (SVATS) in the treatment of thymic tumors. Methods From 2019 to 2021, a retrospective analysis was conducted on patients with thymic tumor resection in the Department of Thoracic Surgery, General Hospital of Northern Theater Command. All patients underwent total thymectomy and mediastinal fat removal, and they were divided into a TNT group and a SVATS group according to the operation method. The intraoperative blood loss, conversion rate, postoperative visual analogue score (VAS), postoperative hospital stay time and postoperative complications were compared between the two groups. Results We finally included 435 patiets. There were 168 patients with 83 males and 85 females at an average age of 61.920±9.210 years in the TNT group and 267 patients with 147 males and 120 females at an average age of 61.460±8.119 years in the SVATS group. There was no death or postoperative myasthenic crisis in both groups. There was no statistical difference in postoperative hospital stay (1.540±0.500 d vs. 3.400±0.561 d, P=0.000), intraoperative blood loss (13.450±5.498 mL vs. 108.610±54.462 mL, P=0.000), postoperative 24 h VAS score (4.960±1.757 points vs. 3.600±1.708 points, P=0.000), or postoperative complication rate (3.0% vs. 11.6%, P=0.001). Conclusion TNT is a more efficient, safe, and effective surgical approach for treating thymic tumors, which can shorten hospital stay time and reduce postoperative complications. However, SVATS can minimize postoperative pain.
ABSTRACT
@#Objective To investigate the clinical effect of three-port Da Vinci robot-assisted radical resection of lung cancer. Methods The clinical data of patients who underwent Da Vinci robot-assisted radical resection of lung cancer in the Second Department of Thoracic Surgery, the First Affiliated Hospital of Xiamen University from April 2021 to March 2022 were retrospectively analyzed. According to the number of surgical ports, they were divided into two groups: a three-port group (three-port Da Vinci robot-assisted radical resection of lung cancer), and a four-port group (traditional Da Vinci robot-assisted radical resection of lung cancer). The operation time, intraoperative bleeding, lymphadenectomy, total thoracic drainage, extubation time, postoperative complications and postoperative pain of the two groups were compared and analyzed. Results A total of 58 patients were included, including 19 males and 39 females, aged 31-79 years. There were 21 patients in the three-port group, and 37 patients in the four-port group. The visual analogue scores on the first and third day after the operation were 4.33±1.20 points and 2.24±0.77 points in the three-port group, and 5.11±1.22 points and 2.78±1.06 points in the four-port group, and there were statistical differences between the two groups (P<0.05). There was no significant difference between the two groups in terms of operation time, intraoperative bleeding, lymph node dissection, postoperative thoracic drainage, time of thoracic tube insertion or postoperative complications (P>0.05). Conclusion Three-port Da Vinci robot-assisted radical resection of lung cancer can reduce the postoperative pain without increasing the operation difficulty and complications, and can be widely used in the clinical practice.
ABSTRACT
@#Objective To summarize the efficacy of robot-assisted thoracic surgery (RATS) and video-assisted thoracoscopic surgery (VATS) in the treatment of left upper lobectomy for non-small cell lung cancer. Methods The clinical data of patients with non-small cell lung cancer who underwent left upper lobectomy with RATS or VATS in our center from January 2019 to October 2021 were retrospectively analyzed. The patients were divided into two groups according to surgical methods: a RATS group and a VATS group. The baseline clinical data and results were compared between the two groups. Results A total of 145 patients were included. There were 78 males and 67 females with a mean age of 59.9 years. There were 63 patients in the RATS group and 82 patients in the VATS group. There was no death within 30 days after operation in both groups. In the RATS group, the drainage volume on the second postoperative day (233.49±83.94 mL vs. 284.88±120.21 mL, P=0.003), total operative time (126.94±29.50 min vs. 181.59±61.51 min, P=0.000), intraoperative resection time of the left upper lobe (76.48±27.52 min vs. 107.23±47.84 min, P=0.000), intraoperative blood loss (P=0.000), and conversion rate to thoracotomy (P=0.018) were significantly better than those in the VATS group. The group (5.41±0.94 groups vs. 4.83±1.31 groups, P=0.002) and number (18.27±7.39 vs. 12.76±6.54, P=0.000) of dissected lymph nodes in the RATS group were significantly more than those in the VATS group. The differences in the drainage volume on the first day after operation, postoperative intubation time, postoperative hospital stay or postoperative complications between the two groups were not statistically significant (P>0.05). Conclusion The application of RATS in the left upper lobectomy for non-small cell lung cancer is safe and feasible, and has obvious advantages over VATS.

ABSTRACT
Objective: To investigate the safety and learning curve of Da Vinci robotic single-anastomosis duodenal-ileal bypass with sleeve gastrectomy (SADI-S) in the treatment of obesity patients. Methods: A descriptive case series study was performed. Clinical data of obesity patients who were treated with Da Vinci robotic SADI-S in China-Japan Union Hospital of Jilin University from March 2020 to May 2021 were analyzed retrospectively. Case inclusion criteria: (1) uncomplicated obese patients with body mass index (BMI)≥37.5 kg/m(2); (2) patients with BMI of 28 to <37.5 kg/m(2) complicated with type 2 diabetes or two metabolic syndrome components, or obesity comorbidities; (3) patients undergoing SADI-S by Da Vinci robotic surgery system. Those who received other bariatric procedures other than SADI-S or underwent Da Vince robotic SADI-S as revisional operation were excluded. A total of 77 patients were enrolled in the study, including 31 males and 46 females, with median age of 33 (18-59) years, preoperative body weight of (123.0±26.2) kg, BMI of (42.2±7.1) kg/m(2) and waistline of (127.6±16.3) cm. According to the order of operation date, the patients were numbered as 1-77. The textbook outcome (TO) and Clavien-Dindo grading standard were used to analyze the clinical outcome of each patient and to classify surgical complications, respectively. The standard of textbook outcome was as follows: the operative time less than or equal to the 75th percentile of the patient's operation time (210 min); the postoperative hospital stay less than or equal to the 75th percentile of the patient's postoperative hospital stay (7 d); complication grade lower than Clavien grade II; no readmission; no conversion to laparotomy or death. The patient undergoing robotic SADI-S was considered to meet the TO standard when meeting the above 5 criteria. The TO rate was calculated by cumulative sum analysis (CUSUM) method. The curve was drawn by case number as X-axis and CUSUM (TO rate) as Y-axis so as to understand the learning curve of robotic SADI-S. Results: The operative time of 77 robotic SADI-S was (182.9±37.5) minutes, and the length of postoperative hospital stay was 6 (4-55) days. There was no conversion to laparotomy or death. Seven patients suffered from complications (7/77, 9.1%). Four patients had grade II complications (5.2%), including one with duodeno-ileal anastomotic leakage, one with abdominal bleeding, one with peritoneal effusion and one with delayed gastric emptying; two patients were grade IIIb complications (2.6%) and both of them were diagnosed with gastric leakage; one patient was grade IV complication diagnosed with postoperative respiratory failure (1.3%), and all of them were cured successfully. A total of 51 patients met the textbook outcome standard, and the TO rate was positive and was steadily increasing after the number of surgical cases accumulated to the 46th case. Taking the 46th case as the boundary, all the patients were divided into learning stage group (n=46) and mastery stage group (n=31). There were no significant differences between the two groups in terms of gender, age, weight, body mass index, waist circumference, ASA classification, standard liver volume, operative time and morbidity of postoperative complication (all P>0.05). The percent of abdominal drainage tube in learning stage group was higher than that in mastery stage group (54.3% versus 16.1%, P<0.05). The length of postoperative hospital stay in learning stage group was longer than that in mastery stage group [6 (4-22) d versus 6 (5-55) d, P<0.05)]. Conclusion: The Da Vinci robotic SADI-S is safe and feasible with a learning curve of 46 cases.

Follow-up was conducted using out-patient examination and telephone interview to detect recurrent gastrointestinal hemorrhage and gastric retention up to July 2021. Measurement data with normal distribution were represented as Mean± SD and measurement data with skewed distribution were represented as M(range). Count data were described as absolute numbers. Results:All 10 patients underwent Da Vinci robotic assisted nerve-preserving splenectomy and azygoportal disconnection successfully, with intraopera-tive autologous blood transfusion and without conversion to open laparotomy or allogeneic blood transfusion. The operation time, volume of intraoperative blood loss, time to initial diet intake and time for out-of-bed activity of 10 patients were (180±14)minutes, (111±28)mL, (1.5±0.5)days and (2.5±0.7)days, respectively. Of the 10 patients, 1 case underwent mild pancreatic leakage, 1 case underwent pneumonia, 2 cases underwent portal vein thrombosis and 3 cases underwent splenic vein thrombosis. Patients with postoperative complications was cured after conservative treatment. The duration of postoperative hospital stay of 10 patients was (8.9±0.9)days. All 10 patients were discharged without perioperative death and followed up for 1 to 4 months, with a median follow-up time of 3 months. There was no patient undergoing gastrointestinal hemorrhage and gastric reten-tion.Conclusion:Da Vinci robotic assisted vagus nerve-preserving splenectomy and azygoportal disconnection is safe and feasible for the treatment of cirrhotic portal hypertension patients with esophagogastric variceal bleeding and hypersplenism.
ABSTRACT
@#Objective To 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. Methods A 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. Results Compared 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). Conclusion RATS is superior to VATS in the treatment of non-small cell lung cancer in perioperative indicators and inflammatory factors.
ABSTRACT
@#Objective To explore the factors that affect the drainage time of da Vinci robot lung cancer surgery, to analyze the coping strategies, and to provide a basis for shortening the drainage time of patients after surgery and speeding up the patients' recovery. Methods The clinical data of 131 patients who underwent da Vinci robot lung cancer surgery at the Department of Thoracic Surgery, General Hospital of Northern Theater Command from January 2019 to October 2019 were retrospectively analyzed. Among them, 68 were males and 63 were females, with an average age of 59.84±9.66 years. According to the postoperative thoracic drainage time, the patients were divided into two groups including a group A (drainage time≤ 5 days) and a group B (drainage time >5 days). Univariate analysis and logistic multivariate regression analysis were used to analyze the factors that may affect postoperative drainage time, and the correlation between different influencing factors and thoracic drainage time after da Vinci robot lung cancer surgery. Results Logistic multivariate analysis showed that age≥60 years (P=0.014), diabetes mellitus (P=0.035), operation time≥130 min (P=0.018), number of lymph node dissections≥15 (P=0.002), and preoperative albumin<38.45 g/L (P=0.010) were independent factors affecting the drainage time of da Vinci robot lung cancer surgery. Conclusion For elderly patients with diabetes mellitus during the perioperative period, blood glucose should be actively controlled, reasonable surgical strategies should be formulated to ensure the safety and effectiveness of the operation, while reducing intraoperative damage and shortening the operation time. After the operation, patients should be guided to strengthen active coughing, expectoration and lung expansion. Thereby it can shorten drainage time and speed up the recovery of patients after operation.
ABSTRACT
@#Objective To evaluate the feasibility and safety of da Vinci robotic surgery for elderly patients with radical surgery of lung cancer. Methods We retrospectively analyzed the clinical data of 59 patients aged over 70 years who underwent radical surgery of lung cancer in our hospital between 2016 and 2019. These patients were divided into two groups including a da Vinci robot group and a single-utility port video-assisted thoracoscopic surgery (VATS) group according to the patients’ selection of the treatments. There were 32 patients with 20 males and 12 females aged 73.1±2.3 years in the da Vinci robot group and 27 patients with 16 males and 11 females aged 71.2±1.3 years in the VATS group. The clinical data of the two groups were compared. Results There was no statistical difference in surgery time between the two groups (t=–0.341, P=0.484). Compared with the VATS group, the da Vinci robot group had more number of lymph nodes dissected (t=1.635, P=0.015), less intraoperative blood loss (t=–2.569, P <0.001), less postoperative drainage amount within 3 days after surgery (t=–6.325, P=0.045), lower visual analogue scale (VAS) scores at postoperative 3rd day (t=–7.214, P=0.021). Conclusion The da Vinci robot system is safe and efficient in the treatment for elderly patients with radical surgery of lung cancer with less trauma.
ABSTRACT
@#Objective To summarize the experience of minimally invasive anterior mediastinal tumor resection in our center, and compare the Da Vinci robotic and video-assisted thoracoscopic approaches in the treatment of mediastinal tumor. Methods A retrospective cohort study was conducted to continuously enroll 102 patients who underwent minimally invasive mediastinal tumor resection between September 2014 and November 2019 by the single medical group in our department. They were divided into two groups: a robotic group (n=47, 23 males and 24 females, average age of 52 years) and a thoracoscopic group (n=55, 29 males and 26 females, average age of 53 years). The operation time, intraoperative blood loss, postoperative thoracic drainage volume, postoperative thoracic drainage time, postoperative hospital stay, hospitalization expense and other clinical data of two groups were compared and analyzed. Results All the patients successfully completed the surgery and recovered from hospital, with no perioperative death. Myasthenia gravis occurred in 4 patients of the robotic group and 5 of the thoracoscopic group. The tumor size was 2.5 (0.8-8.7) cm in the robotic group and 3.0 (0.8-7.7) cm in the thoracoscopic group. Operation time was 62 (30-132) min in the robotic group and 60 (29-118) min in the thoracoscopic group. Intraoperative bleeding volume was 20 (2-50) mL in the robotic group and 20 (5-100) mL in the thoracoscopic group. The postoperative drainage volume was 240 (20-14 130) mL in the robotic group and 295 (20-1 070) mL in the thoracoscopic group. The postoperative drainage time was 2 (1-15) days in the robotic group and 2 (1-5) days in the thoracoscopic group. There was no significant difference between the two groups in the above parameters and postoperative complications (P>0.05). The postoperative hospital stay were 3 (2-18) days in the robotic group and 4 (2-14) in the thoracoscopic group (P=0.014). The hospitalization cost was 67 489 (26 486-89 570) yuan in the robotic group and 27 917 (16 817-67 603) yuan in the thoracoscopic group (P=0.000). Conclusion Compared with the video-assisted thoracoscopic surgery, Da Vinci robot-assisted surgery owns the same efficacy and safety in the treatment of mediastinal tumor, with shorter postoperative hospital stay, but higher cost.
ABSTRACT
@#Objective To analyze risk factors for chronic cough after minimally invasive resection of non-small cell lung cancer (NSCLC) and explore the possible prevention measures. Methods A total of 128 NSCLC patients who received minimally invasive resection in 2018 in our hospital were enrolled, including 63 males and 65 females with an average age of 60.82±9.89 years. The patients were allocated into two groups: a robot-assisted thoracic surgery (RATS) group (56 patients) and a video-assisted thoracic surgery (VATS) group (72 patients). Chronic cough was assessed by visual analogue scale (VAS), meanwhile, other perioperative indicators were compared between the two groups. Univariate and multivariate logistic regression analyses were performed to identify risk factors for postoperative chronic cough and explore the prevention strategies. Results Overall, 61 (47.7%) patients were diagnosed with chronic cough after surgery, including 25 (44.6%) patients in the RATS group and 36 (50.0%) patients in the VATS group, and the difference was not statistically significant (P>0.05). Compared with the VATS group, the RATS group got shorter endotracheal intubation time (P=0.009) and less blood loss (P<0.001). The univariate analysis showed that age (P=0.014), range of surgery (P=0.021), number of dissected lymph nodes (P=0.015), preoperative cough (P=0.006), endotracheal intubation time (P=0.004) were the influencing factors for postoperative chronic cough. The multivariate analysis showed that age <57 years (OR=3.006, 95%CI 1.294-6.986, P=0.011), preoperative cough (OR=3.944, 95%CI 4.548-10.048, P=0.004), endotracheal intubation time ≥172 min (OR=2.316, 95%CI 1.027-5.219, P=0.043), lobectomy (OR=2.651, 95%CI 1.052-6.681, P=0.039) were the independent risk factors for chronic cough. Conclusion There is no statistical difference in postoperative chronic cough between the RATS and VATS groups. The RATS group gets less blood loss and shorter endotracheal intubation time. Patients with younger age (<57 years), preoperative cough, lobectomy, and longer duration of endotracheal intubation (≥172 min) are more likely to have chronic cough after surgery.
