Abstract： Objective To investigate strategies for prevention，early diagnosis，and prompt treatment for acute pulmonary embolism（PE）after video-assisted thoracoscopic surgery（VATS）lobectomy. Methods From January 2007 to November 2010, 1 115 patients with lung cancer underwent VATS lobectomy in the First Affiliated Hospital of Guangzhou Medical College. Among them, 13 patients had acute PE postoperatively, including 6 male patients and 7 female patients with their mean age of 62.3 years（ranging from 42 to 73 years）.All the patients were diagnosed by spiral CT pulmonary artery angiography（SCTPA）, and received anticoagulation therapy with low molecular weight heparin and warfarin. Results The incidence of acute PE after VATS lobectomy was 1.17%（13/1 115）, and the patients with low PE-related early mortality risk accounted for a large proportion（11/13）. There were 12 patients with right-side PE. All the patients’ signs and symptoms were significantly alleviated after administration of anticoagulation therapy. Nine patients received SCTPA review after treatment which showed that their PE had disappeared or been significantly absorbed. No hematological complications including thoracic hemorrhage or wound errhysis occurred after treatment. All surviving patients were followed up for 1 month to 3 months. During follow-up, these patients were alive without PE recurrence. Conclusion SCTPA is the first-choice examination for the diagnosis of acute PE after VATS lobectomy. Prophylaxis against PE and prompt treatment are necessary depending on individual manifestations. VATS lobectomy should be favored as a minimally invasive surgical treatment for patients with lung cancer, for the low incidence of postoperative PE and low PE-related early mortality risk.
Objective To evaluate the safety，efficacy，short- and long-term clinical outcomes of complete video-assisted thoracoscopic surgery （VATS） lobectomy for non-small cell lung cancer （NSCLC）. Methods Clinical data of231 consecutive patients with NSCLC who underwent complete VATS lobectomy in the First Affiliated Hospital of NanjingMedical University between June 2006 and March 2011 were retrospective analyzed. There were 132 male and 99 femalepatients with their age of 15-81 （59.51±11.90） years. Preoperative cancer staging wasⅠa in 149 patients，Ⅰb in 50 patients，Ⅱa in 14 patients，Ⅱb in 13 patients and Ⅲa in 5 patients. There were 152 patients with adenocarcinoma，41 patients with squamous carcinoma，23 patients with bronchioalveolar carcinoma，5 patients with adenosquamous carcinoma，4 patients with large cell carcinoma，and 6 patients with other carcinoma. Follow-up data were statistically analyzed，and short-and long-term survival rates were calculated. Results No perioperative mortality was observed. Operation time was 60-370（199.14±51.04） minutes，and intraoperative blood loss was 10-2 300 （168.19±176.39） ml. Thirty-seven patients had postoperative complications including air leak，pulmonary infection，atelectasis，arrhythmia，subcutaneous emphysema andothers，who were all cured after conservative treatment. Mean number of dissected lymph nodes was 11.14±5.49，and meannumber of explored nodal stations was 3.66±1.52. There were 51 patients （22.08%） whose postoperative cancer staging wasmore advanced than preoperative cancer staging. Postoperative hospital stay was 3-36 （10.79±5.13） days. Primary causesof prolonged postoperative hospitalization included pulmonary air leak，pulmonary infection，preoperative concomitant chronic pulmonary diseases （COPD，asthma），and moderate to severe pulmonary dysfunction. A total of 228 patients werefollowed up for a mean duration of 40.83 months （22-82 months），and 3 patients were lost during follow-up. Overall 5-yearsurvival rates were 85.78%，52.54% and 32.70% for stageⅠ，stageⅡand stageⅢ-Ⅳpatients respectively. Five-year cancerfreesurvival rates were 80.00%，45.37% and 20.99% for stageⅠ，stageⅡand stageⅢ-Ⅳpatients respectively. ConclusionThe advantages of VATS lobectomy include smaller surgical incision，less injury and postoperative pain，quicker postoperative recovery and shorter hospital stay. Long-term survival rate is comparable to previous international and Chinese studies. VATS lobectomy can anatomically achieve complete tumor resection and systematic lymph node dissection. VATS lobectomy will become a standard surgical procedure for NSCLC patients.
Abstract： Objective To evaluate the safety, feasibility, and clinical outcome of complete video-assisted thoracoscopic surgery （VATS） lobectomy for patients with early-stage non-small cell lung cancer （NSCLC）. Methods We retrospectively analyzed the clinical data of 160 consecutive patients（the VATS group, 83 males and 77 females with average age at 60.8 years）with early-stage NSCLC who underwent complete VATS lobectomy between January 2005 andDecember 2008 in Zhongshan Hospital of Fudan University，and compared them with 357 patients（the thoracotomy group, 222 males and 135 females with average age at 59.5 years）who underwent open thoracotomy in the same period. Results The conversion rate of the VATS group was 5.0%（8/160）. The operation time of the VATS group was significantly shorter than that of the thoracotomy group（113.0 min vs.125.0 min, P=0.039）. Length of postoperative hospital stay was not statistically different between the two groups（10.3±4.3 d vs.9.1±4.6 d，P=0.425）. The postoperative morbidity of the VATS lobectomy group and the thoracotomy group was 9.4%（15/160）and 10.1% （36/357） respectively，and the postoperative mortality of the two groups was 0.6%（1/160）and 2.0%（7/357）respectively. There was no statistical difference in the mean group of lymph node dissection （2.4±1.5 groups vs.2.4±1.7 groups，P=0.743） and the mean number of lymph node dissection （9.8±6.3 vs.10.1±6.4，P=0.626） between the two groups. The overall 5-year survival rate of the VATS group was significantly higher than that of the thoracotomy group （81.5% vs.67.8%, P=0.001）. Subgroup analysis showed that the 5-year survival rate of pⅠa stage, pⅠb stage, and pⅢa stage was 86.0%, 84.5%, and 58.8% respectively in the VATS group, and 92.9%, 76.4%, and 25.3% respectively in the thoracotomy group. Conclusion Complete VATS lobectomy is technically safe and feasible for patients with early-stage NSCLC. The lymph node dissection extension of complete VATS lobectomy is similar to that of open thoracotomy, and long-term outcome of complete VATS lobectomy is superior to that of open thoracotomy. Randomized controlled trials of large sample size are further needed to demonstrate superiority.
Objective To assess the safety and clinical outcomes of segmentectomy in one- or two-staged video-assisted thoracoscopic surgery (VATS) for bilateral lung cancer. MethodsWe retrospectively enrolled 100 patients who underwent VATS segmentectomy for bilateral lung cancer at the Department of Thoracic Surgery of Peking Union Medical College Hospital from December 2013 to May 2022. We divided the patients into two groups: a one-stage group (52 patients), including 17 males and 35 females with a mean age of 55.17±11.09 years, and a two-stage group (48 patients), including 16 males and 32 females with a mean age of 59.88±11.48 years. We analyzed multiple intraoperative variables and postoperative outcomes. Results All 100 patients successfully completed bilateral VATS, and at least unilateral lung received anatomical segmentectomy. Patients in the one-stage group were younger (P=0.040), had lower rate of comorbidities (P=0.030), were less likely to have a family history of lung cancer (P=0.018), and had a shorter interval between diagnosis and surgery (P=0.000) compared with patients in the two-stage group. Wedge resection on the opposite side was more common in the one-stage group (P=0.000), while lobectomy was more common in the two-stage group. The time to emerge from anesthesia in the one-stage group was longer than that in the first and second operations of the two-stage group (P=0.000, P=0.002). Duration of surgery and anesthesia were similar between two groups (P>0.05). Total number of lymph node stations for sampling and dissection (P=0.041) and lymph nodes involved (P=0.026) were less in the one-stage group. Intraoperative airway management was similar between two groups (P>0.05). The one-stage group was associated with lower activities of daily living (ADL) scores. Conclusion Segmentectomy is safe in one- or two-staged VATS for bilateral lung cancer, including contralateral sublobectomy and lobectomy. Duration of surgery and perioperative complications are similar between two groups, but the one-stage group is associated with lower ADL scores. On the basis of comprehensive consideration in psychological factors, physical conditions and personal wishes of patients, one-staged sequential bilateral VATS can be the first choice.
ObjectiveTo investigate the impact of chronic obstructive pulmonary disease (COPD) and surgical approach on postoperative fast track recovery and hospitalization cost of patients undergoing lung cancer resection, and explore clinical pathways and clinical value of fast track recovery. MethodClinical data of 129 consecutive patients undergoing lung cancer resection by one surgical group in West China Hospital from January 2010 to March 2011 were retrospectively analyzed. According to whether the patients had concomitant COPD, all the patients were divided into COPD group including 53 patients (39 males and 14 females) with their average age of 56.31±10.51 years, and non-COPD group including 76 patients (37 males and 39 females) with their average age of 65.92±7.85 years. According to different surgical approaches, all the patients were divided into complete video-assisted thoracoscopic surgery (VATS) group including 83 patients (44 males and 39 females) with their average age of 61.62±10.80 years, and routine thoracotomy group including 46 patients (32 males and 14 females) with their average age of 62.95±9.97 years. Postoperative morbidity, average hospital stay and hospitalization cost were compared between respective groups. ResultsThere was no statistical difference in postoperative morbidity (53% vs. 40%, P=0.134)or average hospital stay[(7.66±2.95) days vs. (7.36±2.74)days, P=0.539] between COPD group and non-COPD group. Postoperative morbidity (34% vs. 65%, P < 0.001)and average hospital stay[(6.67±2.52)days vs. (8.61±3.01) days, P < 0.001] of VATS group were significantly lower or shorter than those of routine thoracotomy group. Total hospitalization cost (￥44 542.26±11 447.50 yuan vs. ￥23 634.13±6 014.35 yuan, P < 0.001) and material cost (￥37 352.53±11 807.81 yuan vs. ￥12 763.08±7 124.76 yuan, P < 0.001) of VATS group were significantly higher than those of routine thoracotomy group. Average medication cost of VATS group was significantly lower than that of routine thoracotomy group (￥7 473.54±4 523.70 vs. ￥10 176.71±6 371.12, P < 0.001). There was no statistical difference in other cost between VATS group and routine thoracotomy group. ConclusionVATS lobectomy can promote postoperative fast track recovery of lung cancer patients, but also increase material cost of the surgery. COPD history does not influence postoperative fast track recovery or hospitalization cost.
ObjectiveTo evaluate the safety, efficacy, and cost-effectiveness of different uses of oxidized regenerated cellulose (ORC) in video-assisted thoracoscopic surgery (VATS) for lung cancer resection to provide a reference for the selection, clinical use, and rational utilization of absorbable hemostatic materials. MethodsA retrospective analysis of relevant data from inpatients who underwent VATS for lung cancer resection at a tertiary hospital from July 2019 to January 2020 and from July 2020 to December 2020 was conducted. Patients were divided into two groups based on the use of ORC: 1) combined use group (ORC and collagen sponge) and 2) sole-use group (ORC). Safety, efficacy, and economic outcome indicators were compared between the two groups. ResultsThe main analysis included a total of 904 patients, with 466 in the combined use group and 438 in the sole-use group. Compared to the combined use group, the sole-use group had a significantly longer hospital stay, used fewer hemostatic drugs, had a lower average cost of hemostatic materials, and a lower median total hospitalization cost (P<0.05). No statistically significant difference was found between the two groups in terms of intraoperative blood loss volume, massive blood loss rate, perioperative transfusion rate, reoperation rate, postoperative 48-hour drainage volume, bloody drainage fluid rate, or postoperative laboratory test indicators. ConclusionThere was no significant difference in the safety or efficacy of VATS for lung cancer resection between the sole use of ORC and the combined use of ORC, but the sole use of ORC was associated with a lower cost of hemostatic materials and a lower total hospitalization cost. The sole use of hemostatic gauze in VATS for lung cancer resection may be a more cost-effective choice.
ObjectiveTo investigate the efficacy of total thoracoscopy (VATS) lobectomy and the thoracotomy for the treatment of benign lung disease. MethodsWe retrospectively analyzed the clinical data of 70 patients with benign lung diseases in the First People's Hospital of Qujing between January 2012 and September 2013. According to the surgical way, the patients were divided into two groups including a total VATS group involved in 35 patients with 25 males and 10 females, aged 18 to 71 years, mean age of 41.3±6.4 years and a thoracotomy group involved in 35 patients with 26 males and 9 females, aged 19 to 72 years, mean age of 42.4±5.6 years. Then we compared the efficacy of the two groups. ResultsThere was no statistical difference (P > 0.05) in operative time and postoperative survival rate comparison. While in the total VATS group, the total thoracoscopic incision length, bleeding volume or pain time, postoperative day time of analgesia, thoracic drainage volume, postoperative drainage tube pulling time and hospitalization time were all lower than those in the thoracotomy group with statistical differeces (P < 0.05). ConclusionThe thoracoscopic lobectomy for treatment of benign pulmonary lesions is superior to the conventional thoracotomy with much less bleeding and pain, more faster postoperative recovery and less impact on the patient's body. It's suitable for clinical application in normal hospital.
Objective To evaluate the efficacy and safety of total thoracoscopic lobectomy for patients with stage Ⅰ/Ⅱ non-small cell lung cancer (NSCLC). Methods The clinical data of 138 NSCLC patients from January 2013 to June 2015 in Shaanxi People's Hospital were retrospectively analyzed. There were 88 males and 50 females with an average age of 57.4±8.8 years, ranging from 44 to 76 years. According to the operation methods, they were divided into a video-assisted thoracoscopic surgery (VATS) group (thoracoscopic lobectomy in 63 cases) and a thoracotomy group (conventional open chest surgery in 75 cases). The intra- and postoperative clinical data, surgical complications and pulmonary function were compared. Results There was no significant difference in the operation time, intraoperative lymph node dissection groups, intraoperative lymph node dissection number between two groups (P>0.05). The blood loss, postoperative drainage volume, duration of postoperative analgesia, Numeric Rating Scale for pain and hospital stay in the VATS group were significantly lower than those of the thoracotomy group (P<0.05). The pre- and postoperative FVC%pred and FEV1%pred in both groups were compared and there was no significant difference (P>0.05). However the postoperative FVC%pred and FEV1%pred in both groups significantly reduced compared with preoperative ones (P<0.05). Complication rate of thoracoscopic group was significantly less than that of the thoracotomy group (20.63%vs. 32.00%,χ2=3.974,P=0.046). Conclusion Thoracoscopic lobectomy for NSCLCⅠ/Ⅱpatients is reliable, and achieves rapid postoperative recovery as well as less complications.
ObjectiveTo explore clinical outcomes of simutaneous video-assisted thoracoscopic surgery (VATS) for bilateral giant bullae (GB). MethodsClinical data of 160 GB patients who received surgical treatment in the First Affiliated Hospital of Xinjiang Medical University from March 2011 to April 2013 were retrospectively analyzed. According to GB location and surgical strategies, all the patients were divided into 3 groups. In group A, there were 108 patients with spontaneous pneumothorax (SP) and unilateral GB who underwent unilateral GB resection with VATS, including 88 male and 20 female patients with their age of 31.36±16.14 years. In group B, there were 40 patients with SP and bilateral GB who underwent unilateral GB resection in the SP side with VATS, including 36 male and 4 female patients with their age of 37.63±18.84 years. In group C, there were 12 patients with SP and bilateral GB who underwent simultaneous bilateral GB resection with VATS, including 9 male and 3 female patients with their age of 32.58±16.06 years. Postoperative morbidity and SP recurrence rates were analyzed. ResultsAll the operations were successfully performed, and patients were followed up for 20 months after discharge. In group A, postoperative complications included acute pulmonary edema in 1 patient, pleural adhesion in 11 patients, respiratory failure in 2 patients, and pulmonary air leak in 5 patients. During follow-up, SP recurred in 5 patients including 2 patients with SP recurrence at the same side and 3 patients with SP recurrence at the other side of thorax. In group B, postoperative complications included pleural adhesion in 4 patients, respiratory failure in 1 patient, and pulmonary air leak in 3 patients. During follow-up, SP recurred in 18 patients including 3 patients with SP recurrence at the same side and 15 patients with SP recurrence at the other side of thorax. In group C, postoperative complications included pleural adhesion in 2 patients and pulmonary air leak in 1 patient. During follow-up, SP recurred in 1 patient at the same side of thorax. SP recurrence rates of group A and C were significantly lower than that of group B (P=0.000 and P=0.031 respectively). ConclusionSimultaneous VATS is safe, efficacious and reliable for the treatment of bilateral GB, and can effectively prevent SP recurrence at the other side of thorax.
ObjectiveTo investigate the feasibility,safety and short-term clinical outcomes of complete videoassisted thoracoscopic surgery (VATS) lobectomy for patients with early-stage lung cancer (LC). MethodsClinical data of 138 consecutive patients with early-stage LC who underwent lobectomy in the First People's Hospital of Jining from January 2012 to May 2013 were retrospectively analyzed. There were 71 patients undergoing complete VATS lobectomy including 39 male and 32 female patients with their age of 57.9±10.6 years (VATS group) and 67 patients undergoing lobectomy via traditional thoracotomy including 36 male and 31 female patients with their age of 60.3±8.2 years (thoracotomy group). Operation time,intraoperative blood loss, groups and number of lymph node dissection,thoracic drainage duration, postoperative hospital stay,vision analogue scores (VAS) on the 1st,3rd and 30th postoperative day, and postoperative morbidity were compared between the 2 groups. ResultsAll the patients in both groups success fully received their operation. Intraoperative blood loss (147±113 ml vs. 146±91 ml) number of lymph node dissection (9.9±3.6 vs. 10.0±3.6) group of lymph node dissection (3.1±1.3 vs. 3.4±1.3) and VAS on the 1st and 3rd postoperative day of VATS group were not statistically different from those of the thoracotomy group (P>0.05). Operation time (119±27 minutes vs. 135±29 minutes) thoracic drainage duration (3.0±0.9 days vs. 3.8±1.2 days) postoperative hospital stay (8.0±2.1 days vs. 10.2±5.4 days) VAS on the 30th postoperative day (2.6±0.7 vs. 3.2±1.1) and postoperative morbidity (8.5% vs. 19.4%) of VATS group were significantly shorter or lower than those of the thoracotomy group (P<0.05). Fifty-nine patients in VATS group and 58 patients in the thoracotomy group were followed up for 2-18 months after disc harge. During follow-up,there was no death in either group. There was 1 patient with brain metastasis,1 patient with liver metastasis,and 2 patients with bone metastasis. ConclusionComplete VATS lobectomy is safe and feasible for the treatment of early LC with the advantages of minimal invasiveness,less morbidity,better postoperative recovery and less chronic incision pain. Complete VATS lobectomy can also achieve similar standardization of lymph node dissection as routine thoracotomy.
