ObjectiveTo investigate the effects of closed thoracic drainage with single tube or double tubes after video-assisted thoracoscopic lung volume reduction surgery.MethodsRetrospective analysis was performed on 50 patients (39 males, 11 females) who underwent three-port thoracoscopic lung volume reduction surgery in our hospital from January 2013 to March 2019. Twenty-five patients with single indwelling tube after surgery were divided into the observation group and 25 patients with double indwelling tubes were divided into the control group.ResultsThere was no significant difference in pulmonary retension on day 3 after surgery, postoperative complications, the patency rate of drainage tube before extubation, retention time or postoperative hospital stay (P>0.05). Postoperative pain and total amount of nonsteroidal analgesics use in the observation group was less than those in the control group (P<0.05). ConclusionIt is safe and effective to perform closed thoracic drainage with single indwelling tube after video-assisted thoracoscopic lung volume reduction surgery, which can significantly reduce the incidence of related adverse drug reactions and facilitate rapid postoperative rehabilitation with a reduction of postoperative pain and the use of analgesic drugs.
ObjectiveTo summarize the clinical experience of the uniportal thoracoscopic anatomical sub-segmentectomy of the basal segment. MethodsThe clinical data of 34 patients who underwent uniportal thoracoscopic anatomical sub-segmentectomy of the basal segment in our department between April 2018 and April 2021 were retrospectively analyzed. There were 19 males and 15 females with a median age of 56.5 (28.0-76.0) years, a 3-4 cm incision was made in the 5th intercostal area at the front axillary line, and anatomical sub-segmentectomy of the basal segment was performed. Results The surgery was successfully performed in all patients, and there was no patient with additional chest incision or transfer to thoracotomy. The median operation time was 165.0 (125.0-220.0) min, intraoperative blood loss was 120.0 (70.0-290.0) mL, thoracic drainage time was 3.5 (2.0-24.0) d, and hospitalization time was 6.0 (3.0-26.0) d. There was no death during the hospitalization. Postoperative complications included 4 patients of atrial fibrillation, 2 patients of blood sputum, 3 patients of persistent air leakage, and they were recovered after conservative treatment. One patient developed pneumothorax after discharge, 1 patient developed pleural effusion, and both of them recovered after drainage. Postoperative pathology showed microinvasive adenocarcinoma in 22 patients, adenocarcinoma in situ in 7 patients, benign tumors in 5 patients. The lymph nodes were negative in all patients. Conclusion The uniportal thoracoscopic anatomical sub-segmentectomy of the basal segment is safe and feasible, and can be popularized and applied in clinic.
ObjectiveTo explore the safety and feasibility of 3D precise localization based on anatomical markers in the treatment of pulmonary nodules during video-assisted thoracoscopic surgery (VATS).MethodsFrom June 2019 to April 2015, 27 patients with pulmonary nodules underwent VATS in our Hospital were collected in the study, including 3 males and 24 females aged 51.8±13.7 years. The surgical data were retrospectively reviewed and analyzed, such as localization time, localization accuracy rate, pathological results, complication rate and postoperative hospital stay.ResultsA total of 28 pulmonary nodules were localized via this method. All patients received surgery successfully. No mortality or major morbidity occurred. The general mean localization time was 17.6±5.8 min, with an accuracy of 96.4%. The mean diameter of pulmonary nodules was 14.0±8.0 mm with a mean distance from visceral pleura of 6.5±5.4 mm. There was no localization related complication. The mean postoperative hospital stay was 6.7±4.3 d. The routine pathological result showed that 78.6% of the pulmonary nodules were adenocarcinoma.Conclusion3D precise localization based on anatomical markers in the treatment of pulmonary nodules during thoracoscopic surgery is accurate, safe, effective, economical and practical, and it is easy to master with a short learning curve.
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.
ObjectiveTo explore the safety, feasibility and superiority of tubeless video-assisted thoracoscopic surgery (VATS) in the treatment of spontaneous pneumothorax.MethodsWe retrospectively analyzed the clinical data of 38 patients with primary spontaneous pneumothorax treated in our hospital from February 2017 to July 2018. Tubeless bullectomy was performed in 18 patients, including 11 males and 7 females, aged 14.3±1.5 years. Twenty patients underwent conventional thoracoscopic bullae resection, including 12 males and 8 females, aged 14.5±1.7 years. The clinical effectiveness was compared.ResultsAll the 38 patients completed the operation successfully under the single-port thoracoscopy, without the transfer of intubation and secondary surgery. Operation time (67.3±13.3 min vs. 81.4±13.4 min, P=0.002), preoperative anesthesia time (14.2±2.6 min vs. 18.5±2.6 min, P=0.000), postoperative anesthesia recovery time (17.1±2.6 min vs. 26.5±5.0 min, P=0.000), visual simulation score of postoperative pain (2.3±0.9 vs. 5.2±1.0, P=0.000), postoperative activity time (1.3±0.4 d vs. 2.9±0.6 d, P=0.000), postoperative hospitalization time (2.9±0.8 d vs. 5.6±1.3 d, P=0.000), hospitalization cost (35.0±6.0 kyuan vs. 59.0±10.0 kyuan, P=0.000) were better in the control group. There was no significant difference in intraoperative blood loss (73.2±4.6 mL vs. 73.9±4.1 mL) and postoperative lung revascularization time (29.3±2.4 h vs. 29.7±2.5 h) between the two groups (P>0.05).ConclusionCompared with traditional thoracoscopic bullectomy, tubeless VATS technique is safe and reliable in the treatment of spontaneous pneumothorax, with mild pain and quick recovery, in line with the concept of fast track surgery and worthy of clinical promotion.
ObjectiveTo discuss the safety and feasibility of no chest tube (NCT) after thoracoscopic pneumonectomy.MethodsThe online databases including PubMed, EMbase, The Cochrane Library, Web of Science, China National Knowledge Infrastructure (CNKI), WanFang Database, VIP, China Biology Medicine disc (CBMdisc) were searched by computer from inception to October 2020 to collect the research on NCT after thoracoscopic pneumonectomy. Two reviewers independently screened the literature, extracted the data, and evaluated the quality of the included studies. The RevMan 5.3 software was used for meta-analysis.ResultsA total of 17 studies were included. There were 12 cohort studies and 5 randomized controlled trials including 1 572 patients with 779 patients in the NCT group and 793 patients in the chest tube placement (CTP) group. Meta–analysis results showed that the length of postoperative hospital stay in the NCT group was shorter than that in the CTP group (SMD=–1.23, 95%CI –1.59 to –0.87, P<0.000 01). Patients in the NCT group experienced slighter pain than those in the CTP group at postoperative day (POD)1 (SMD=–0.97, 95%CI –1.42 to –0.53, P<0.000 1), and POD2 (SMD=–1.10, 95%CI –2.00 to –0.20, P=0.02), while no statistical difference was found between the two groups in the visual analogue scale of POD3 (SMD=–0.92, 95%CI –1.91 to 0.07, P=0.07). There was no statistical difference in the 30-day complication rate (RR=0.93, 95%CI 0.61 to 1.44, P=0.76), the rate of postoperative chest drainage (RR=1.51, 95%CI 0.68 to 3.37, P=0.31) or the rate of thoracocentesis (RR=2.81, 95%CI 0.91 to 8.64, P=0.07) between the two groups. No death occurred in the perioperative period in both groups.ConclusionIt is feasible and safe to omit the chest tube after thoracoscopic pneumonectomy for patients who meet the criteria.
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.
Objective To examine the application effectiveness of dual 8F ultrafine pigtail drainage tubes versus a single 28F large-bore chest tube in single-port thoracoscopic lobectomy/segmentectomy. Methods Clinical data of patients who underwent single-port video-assisted thoracoscopic lobectomy/segmentectomy within our medical group from January 2020 to August 2023 were retrospectively analyzed. They were categorized into two groups based on postoperative drainage methods: a dual 8F ultrafine pigtail tubes group and a single 28F large-bore chest tube group. Comparative analysis was performed on perioperative data for the two groups of patients. Results The dual 8F ultrafine pigtail tubes group comprised of 68 patients, with 41 females and 27 males, and an average age of (54.72±13.34) years, while the single 28F large-bore chest tube group comprised of 80 patients, with 40 females and 40 males, and an average age of (57.60±11.04) years. There were statistical differences between the two groups in terms of postoperative drainage volume on day 1, day 2, and day 3, total postoperative drainage volume, postoperative tube placement time, postoperative pain score at 48 hours, maximum postoperative pain score, postoperative hospital stay, postoperative complications related to drainage tubes, and emergency use of pain-relieving medication after surgery (P＜0.05). Conclusion After single-port thoracoscopic lobectomy/segmentectomy, the application of dual ultrafine 8F pigtail drainage tubes can lead to a reduction in postoperative drainage volume and shorten the duration of postoperative drainage tube placement and hospital stay, thereby decreasing postoperative pain and the frequency of emergency pain-relieving medication. Moreover, it lowers the incidence of drainage tube-related complications. In alignment with current enhanced recovery after surgery principles, this approach is advantageous for postoperative recovery.
Objective To investigate the perioperative differences between video-assisted thoracoscopic surgery (VATS) and thoracotomy after neoadjuvant therapy in patients with non-small cell lung cancer (NSCLC). Methods Clinical data of NSCLC patients who underwent VATS or thoracotomy after neoadjuvant therapy at Shanghai Pulmonary Hospital from June 2020 to May 2022 were retrospectively collected. Perioperative outcomes were compared between the two groups. Results A total of 260 patients were enrolled, 184 (70.8%) patients underwent VATS and 76 (29.2%) patients underwent thoracotomy. After propensity matching, there were 113 (62.4%) patients in the VATS group and 68 (37.6%) patients in the thoracotomy group. VATS had similar lymph node dissection ability and postoperative complication rate with thoracotomy (P>0.05), with the advantage of having shorter operative time (146.00 min vs. 165.00 min, P=0.006), less intraoperative blood loss (50.00 mL vs. 100.00 mL, P<0.001), lower intraoperative blood transfusion rate (0.0% vs. 7.4%, P=0.003), less 3-day postoperative drainage (250.00 mL vs. 350.00 mL, P=0.011; 180.00 mL vs. 250.00 mL, P=0.002; 150.00 mL vs. 235.00 mL, P<0.001), and shorter postoperative drainage time (9.34 d vs. 13.84 d, P<0.001) and postoperative hospitalization time (6.19 d vs. 7.94 d, P=0.006). Conclusion VATS after neoadjuvant therapy for NSCLC is safer than thoracotomy and results in better postoperative recovery.
ObjectiveTo evaluate the correlation between positive end-expiratory pressure (PEEP) level and postoperative pulmonary complications (PPCs) in patients undergoing thoracoscopic lung surgery. MethodsThe clinical data of patients who underwent elective thoracoscopic lung surgery at West China Hospital of Sichuan University from January 2022 to June 2023 were retrospectively analyzed. Patients were divided into 2 groups according to intraoperative PEEP levels: a PEEP 5 cm H2O group and a PEEP 10 cm H2O group. The incidence of PPCs in the two groups after matching was compared using a nearest neighbor matching method with a ratio of 1∶1, setting the clamp value as 0.02. ResultsA total of 538 patients were screened, and after propensity score-matching, a total of 229 pairs (458 patients) were matched, with an average age of 53.9 years and 69.4% (318/458) females. A total of 118 (25.8%) patients had PPCs during hospitalization after surgery, including 60 (26.2%) patients in the PEEP 5 cm H2O group and 58 (25.3%) patients in the PEEP 10 cm H2O group, with no statistically significant difference between the two groups [OR=0.997, 95%CI (0.495, 1.926), P=0.915]. Multivariate logistic regression analysis showed that PEEP was not an independent risk factor for PPCs [OR=0.920, 95%CI (0.587, 1.441), P=0.715]. ConclusionFor patients undergoing thoracoscopic lung surgery, intraoperative PEEP (5 cm H2O or 10 cm H2O) is not associated with the risk of PPCs during hospitalization after surgery, which needs to be further verified by prospective, large-sample randomized controlled studies.
