ABSTRACT
@#Objective To explore the feasibility of early chest tube removal following single-direction uniportal video-assisted thoracoscopic surgery (S-UVATS) anatomical lobectomy. Methods The clinical data of consecutive VATS lobectomy by different surgeons in Xuzhou Central Hospital between May 2019 and February 2022 were retrospectively reviewed. Finally, the data of 1 084 patients were selected for analysis, including 538 males and 546 females, with a mean age of 61.0±10.1 years. These patients were divided into a S-UVATS group with 558 patients and a conventional group (C-UVATS) with 526 patients according to the surgical procedures. The perioperative parameters such as operation time, blood loss were recorded. In addition, we assessed the amount of residual pleural effusion and the probability of secondary thoracentesis when taking 300 mL/d and 450 mL/d as the threshold of chest tube removal. Results Tumor-negative surgical margin was achieved without mortality in this cohort. As compared with the C-UVATS group, patients in the S-UVATS group demonstrated significantly shorter operation time (P<0.001), less blood loss (P=0.002), lower rate of conversion to multiple-port VATS or thoracotomy (P=0.003), but more stations and numbers of dissected lymph nodes as well as less suture staplers (P<0.001). Moreover, patients in the S-UVATS demonstrated shorter chest tube duration, less total volume of thoracic drainage and shorter postoperative hospital stay, with statistical differences (P<0.001). After excluding patients of chylothorax and prolonged air leaks>7 d, subgroup analysis was performed. First, assuming that 300 mL/d was the threshold for chest tube removal, as compared with the C-UVATS group, patients in the S-UVATS group would report less residual pleural effusion and less necessitating second thoracentesis with residual pleural effusion>500 mL (P<0.05). Second, assuming that 450 mL/d was the threshold for chest tube removal, as compared with the C-UVATS group, the S-UVATS group would also report less residual pleural effusion and less necessitating second thoracentesis with residual pleural effusion>500 mL (P<0.05). Further multivariable logistic regression analysis indicated that S-UVATS was significantly negatively related to drainage volume>1 000 mL (P<0.05); whereas combined lobectomy, longer operation time, more blood loss and air leakage were independent risk factors correlated with drainage volume>1 000 mL following UVATS lobectomy (P<0.05). Conclusion The short-term efficacy of S-UVATS lobectomy is significantly better than that of the conventional group, indicating shorter operation time and less chest drainage. However, early chest tube removal with a high threshold of thoracic drainage volume probably increases the risk of secondary thoracentesis due to residual pleural effusion.
ABSTRACT
@#Objective To investigate the short-term quality of life in patients after single-direction video-assisted thoracic surgery (VATS) for lung cancer, and explore the related influencing factors. Methods Patients who underwent single-direction VATS for lung cancer in the Department of Thoracic Surgery, West China Hospital, Sichuan University from July 2020 to August 2021 were continuously selected. The QLQ-C30 and QLQ-LC13 were used to evaluate the quality of life of the patients after the surgery, and the influencing factors were analyzed. Results A total of 193 patients were collected. There were 73 males aged 59.44±11.40 years, and 120 females aged 53.73±11.15 years. The QLQ-C30 score of the patients after single-direction VATS for lung cancer was 69.09±20.21 points. Univariate analysis and Pearson correlation analysis showed that age, occupation, anesthesia time, postoperative complications, postoperative antibiotic use time, postoperative hospital stay, insomnia, economic stress, hemoptysis, chest pain, dysphagia, arm or shoulder pain were associated with the quality of life (P≤0.05). The results of multiple regression analysis showed that anesthesia time, economic pressure, insomnia and chest pain had a significant impact on the overall quality of life 30 days after the surgery (P≤0.05). Conclusion The anesthesia time, economic pressure, insomnia and chest pain are independent influencing factors for the quality of life after the VATS lung cancer surgery.
ABSTRACT
@#Objective To explore the value of the single-direction lobectomy in the treatment of complicated pulmonary tuberculosis. Methods A 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). Results The 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%)]. Conclusion The 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.
ABSTRACT
@#Objective To explore the safety and feasibility of the modified and improved thoracoscopic surgery for esophageal cancer using the concept of "single-direction" thoracoscopic technique. Methods The clinical data of 65 patients undergoing this modified minimally invasive esophagectomy based on "single-direction" thoracoscopic system between June 2018 and April 2019 were retrospectively analyzed, including 54 males and 11 females aged 62.5±7.8 years. Results The thoracoscopic operation time was 133.4±28.6 min, and intraoperative blood loss was 61.9±29.2 mL. No intraoperative blood transfusion was needed. One patient was transferred to open thoracotomy (due to severe pleural adhesion atresia). Major complications included anastomotic leak, pneumonia, chylothorax, incisional infection, recurrent laryngeal nerve paralysis and gastric emptying disorders, which were recovered by conservative treatment. No postoperative death occurred. The median number of lymph nodes and lymph node station harvested was 19 and 10, respectively. The median postoperative hospital stay was 10 days. The volume of chest drainage was 1 117.3±543.4 mL. Conclusion The minimally invasive operation mode of esophageal cancer based on "single-direction" thoracoscopic system is safe and feasible, and has good field vision and smooth and simplified procedure.
ABSTRACT
@#Objective To evaluate the safety, feasibility and short-term outcomes of single-direction gastric mobilization under 3D-laparoscopy in minimally invasive esophagectomy for the treatment of esophageal cancer. Methods From February 2018 to December 2019, 118 consecutive patients who underwent minimally invasive McKeown esophagectomy for esophageal squamous cell carcinoma in our hospital were included. There were 94 males and 24 females with an average age of 53.7 (41–77) years. They were divided into two groups based on the methods of gastric mobilization: a traditional dissociation (TD) group (n=55) and a single-direction mobilization (MD) group (n=63). The clinical data of the two groups were compared. Results Enbloc resection and a negative resection margin were obtained in all patients. There was no postoperative mortality or incision complication. The rate of postoperative complications was 22.9%. There was no significant difference in the spleen injury, gastric injury, conversion to open surgery, abdominal reoperation as well as cervical anastomotic leakage between the two groups (P>0.05). It took significantly less time in the MD group compared with the TD group (P<0.05). There was an obvious statistical difference in the incidence of gastric mobilization related complications between the MD group (1.6%, 1/63) and TD group (12.7%, 7/55, P<0.05). Conclusion Application of single-direction gastric mobilization under 3D-laparoscopy in minimally invasive esophagectomy for the treatment of esophageal cancer is safe and easy to perform with a satisfactory short-term outcome.
ABSTRACT
@#Objective To 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. Methods Clinical 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. Results There 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. Conclusion The 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.
ABSTRACT
@#Objective To investigate the optimal procedure and short-term efficacy of uniportal video-assisted thoracic surgery (U-VATS) lobectomy for lung cancer. Methods The clinical data of 61 patients who underwent lobectomy using U-VATS by the same surgeon between April 2016 and February 2017 were retrospectively analyzed. There were 50 patients (40 males and 10 females, aged 61.4±6.6 years) with conventional procedure. And there were 60 patients (45 males and 15 females, aged 59.2±9.7 years) utilizing multiportal thoracoscopic surgery (M-VATS) during this period. Results The baseline characteristics in both groups such as age, gender, body mass index, comorbidity and tumor size were comparable (P>0.05). There was no postoperative mortality or conversion to thoracotomy in the study. The parameters such as operative time, blood loss, harvested lymph nodes, duration of chest tube drainage, and length of postoperative hospital stay were similar in both groups (P>0.05). However, there was a statistical difference in pain score at 12 h after surgery in favor of the U-VATS approach (3.2vs.4.3, P=0.04). Moreover, subgroup analysis indicated that the operation time using single-direction U-VATS was noticeably shorter than that in both conventional U-VATS and M-VATS (76.4 minvs.125.8 minvs.105.6 min, P<0.05). However, further analysis was not performed because of small sample. Conclusion The short-term efficacy of U-VATS lobectomy for lung cancer is noninferior to M-VATS, meanwhile, single-direction U-VATS lobectomy is feasible followed by shortened operative time.
