Objective To share the experience of single-stage bilateral pulmonary resections by video-assisted thoracic surgery (VATS) for multiple nodules. Methods Clinical records of patients undergoing one-stage bilateral resections of multiple pulmonary nodules between January 2015 and December 2016 in our institution were retrospectively reviewed and analyzed. There were 9 males and 15 females, aged from 33 to 69 (55.0±8.0) years. Two patients underwent bilateral lobectomy. Lobar-sublobar (L/SL) resection and bilateral sublobar resection (SL-SL) were conducted in 9 patients and 13 patients respectively. Results All operations completed successfully. Operation time was 135–330 (231.4±59.1) min, duration of use of chest drains was 2–17 (5.4±3.1) days. Overall duration of hospitalization after surgery was 5–37 (8.6±6.3) days. There was no perioperative death. Postoperative course was uneventful in 17 (70.8%) patients. The postoperative complications included one patient of incision infection and one patient of pulmonary infection. Persistent air leak for >3 days duration and unilateral pleural drainage for more than 200 ml/d were observed in 3 patients and 2 patients respectively. Conclusion Single-stage bilateral surgery in selected patients with synchronous bilateral multiple nodules is feasible and associated with satisfactory outcomes.
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.
ObjectiveTo investigate the safety and efficiency of robotic lung segmentectomy.MethodsThe clinical data of 110 patients receiving robotic or thoracoscopic segmentectomy in our hospital between June 2015 and June 2019 were retrospectively analyzed. The patients were divided into a robotic group [n=50, 13 males and 37 females aged 53.0 (46.0, 60.0) years] and a thoracoscopic group [n=60, 21 males and 39 females aged 61.0 (53.0, 67.0) years]. A propensity score-matched analysis was adopted to compare the perioperative data between the two groups.ResultsAfter the propensity score-matched analysis, 34 patients were included in each group. In comparison with the thoracoscopic group, patients in the robotic group had less blood loss [40.0 (20.0, 50.0) mL vs. 60.0 (40.0, 80.0) mL, P<0.001], more stations of lymph node dissection [7.0 (6.0, 8.0) vs. 4.0 (3.0, 6.0), P<0.001], larger number of lymph node dissection [15.0 (11.0, 21.0) vs. 10.0 (6.0, 14.0), P=0.002], and a higher total cost of hospitalization [97.0 (92.0, 103.0) thousand yuan vs. 54.0 (42.0, 59.0) thousand yuan, P<0.001].ConclusionIn contrast with the thoracoscopic segmentectomy, robotic segmentectomy has a similar operative safety, but less blood loss and a thorough lymphadenectomy.
ObjectiveTo evaluate the clinical effects of segmentectomy versus lobectomy under single utility port video-assisted thoracic surgery on inflammatory factors and immune cells in peripheral blood of non-small cell lung cancer patients, and to analyze the effect of changes of postoperative inflammatory factors and immune cells on the prognosis of the patients.MethodsThe clinical data of 256 patients who underwent segmentectomy or lobectomy under single utility port video-assisted thoracic surgery for non-small cell lung cancer in the First Affiliated Hospital of Hebei North University from January 2016 to October 2020 were retrospectively collected. According to the operation method, they were divided into a segmentectomy group (126 patients with 79 males and 47 females at an age of 63.4±6.2 years) and a lobectomy group (130 patients with 91 males and 39 females at an age of 62.9±5.6 years). The change of inflammatory factors (C reactive protein, interleukin-6, interleukin-8, tumor necrosis factor-α) and immune cells (CD4+T cells, CD8+T cells and natural killer cells) were recorded and analyzed before operation (T0) and 1 day (T1), 3 days (T2), 7 days (T3), 1 month (T4) after the operation between the two groups. According to postoperative recurrence situations, they were divided into a recurrence group and a non-recurrence group, multivariate logistic regression analysis was used to analyze the relationship between the change of postoperative inflammatory factors, immune cells, and the prognosis of patients with non-small cell lung cancer.Results(1) There was no statistical difference in sex ratio, underlying diseases, body mass index, levels of preoperative inflammatory factors or immune cells between the two groups (all P>0.05). (2) The changes of postoperative inflammatory factors in the segmentectomy group were significantly less than those in the lobectomy group at T1-T3 (all P<0.05), and the changes of postoperative immune cells in the segmentectomy group were significantly less than those in the lobectomy group at T1-T4 (all P<0.05). (3) The changes of postoperative inflammatory factors and immune cells on postoperative day 3 in the recurrence group were significantly more than those in the non-recurrence group (all P<0.05). (4) Multivariate logistic regression analysis showed that the changes of postoperative inflammatory factors and immune cells on postoperative day 3 may be the risk factors for postoperative recurrence and metastasis in patients with non-small cell lung cancer (all P<0.05).ConclusionSingle utility port video-assisted thoracic surgery segmentectomy for the treatment of non-small cell lung cancer can reduce the inflammatory response and protect body's immune function, and the change of postoperative inflammatory factors and immune cells in postoperative day 3 may be the risk factors for postoperative recurrence and metastasis in patients with non-small cell lung cancer.
Objective To evaluate the security and clinical value of the combination of three-dimensional computed tomography-bronchography and angiography (3D-CTBA) and indocyanine green (ICG) staining in video-assisted thoracic surgery (VATS) segmentectomy. Methods The clinical data of 125 patients who received VATS segmentectomy from January 2020 to January 2021 in our hospital were retrospectively analyzed. There were 40 (32.0%) males and 85 (68.0%) females with an average age of 54.8±11.1 years. Results The procedure was almost identical to the preoperative simulation. All intersegment planes were displayed successfully by ICG reverse staining method. There was no allergic patient. A total of 130 pathological specimens were obtained from the 125 patients. The mean operation time was 126.8±41.9 min, the time of first appearance of fluorescence was 22.7±4.9 s, the mean mark time was 65.6±20.3 s, the median blood loss was 20.0 (10.0-400.0) mL, the postoperative hospital stay was 5.6 (4.0-28.0) d, and the postoperative retention of chest tube time was 3.2 (2.0-25.0) d. Pathological results showed that microinvasive adenocarcinoma was the most common type (38.5%, 50/130), followed by invasive adenocarcinoma (36.9%, 48/130); there were 3 metastatic tumors (3/130, 2.3%).Conclusion The combination of 3D-CTBA and ICG reverse staining is proved to be a safe, necessary and feasible method. It solves the difficult work encountered in the procedure of segmentectomy, and it is worth popularizing and applying in clinic.
