Application of uniportal video-assisted thoracoscopic surgery in the treatment of tuberculous destroyed lung

Objective: To examine the efficacy of uniportal video-assisted thoracoscopic surgery in the treatment of tuberculous destroyed lung. Methods: This is a retrospective case series study. The clinical data of 33 patients with tuberculous destroyed lung who had received uniportal video-assisted thoracoscopic pulmonary resection from June 2020 to May 2022 in Department of Surgery, Wuhan Pulmonary Hospital were retrospectively analyzed. There were 13 males and 20 females, aged (47.5±16.2) years (range: 19 to 68 years). The course of the disease was from 15 days to 8 years. All 33 cases had pleural adhesions, including 30 cases with total pleural adhesions and atresia. There were 21 cases of calcification of the thoracic lymph node, 17 cases of aspergillus infection, 4 cases of drug-resistant tuberculosis. The surgical incision was located at the midline of the fifth intercostal axilla, length 4 to 5 cm. The principle of separating pleural adhesions was easy first and difficult later, and then appropriate procedures were selected to resect the diseased lung based on the exploration situation. There were 12 cases that underwent superior lobectomy, 11 cases that underwent superior lobectomy and dorsal segmentectomy, 3 cases that underwent inferior lobectomy, 3 cases that underwent pneumonectomy, 2 cases that underwent middle and inferior lobectomy, and 1 case that underwent superior lobectomy, dorsal segmentectomy and basal segment wedgectomy. The surgical techniques, perioperative evaluation and treatment, management of complications, and the outcome were summarized. Results: Six cases were converted to thoracoscope assisted small incision or thoracotomy. For 27 cases who successfully underwent uniportal VATS, the operation time was (238.7±76.8) minutes (range: 60 to 420 minutes), the intraoperative bleeding was (400.4±315.9) ml (range: 50 to 1 200 ml). The duration of postoperative drainage was (12.7±8.3) days (range: 3 to 42 days). The postoperative hospital stay was (15.2±7.9) days (range: 6 to 43 days). Persistent postoperative pulmonary leakage occurred in 12 cases. There were 2 cases of active thoracic bleeding, one of which was cured with conservative treatment. The other case underwent secondary operation. One case of bronchopleural fistula was cured after continuous thoracic drainage to control infection and implantation of one-way bronchial valve through a fiberoptic bronchoscope. Conclusion: For selected patients with tuberculous destroyed lung, choosing the reasonable surgical procedures and techniques, the uniportal VATS could reduce surgical trauma.

Comparative efficacy of prophylactic protocols in reducing perioperative nausea and vomiting during video-assisted thoracoscopic radical resection of lung cancer

Lung cancer, a global mortality leader, often necessitates Video-Assisted Thoracoscopic (VATS) surgery. However, post-operative nausea and vomiting (PONV) is common, highlighting a need for effective management and prevention strategies in this context. A retrospective case–control study at Fujian Medical University Union Hospital evaluated patients undergoing VATS radical resection of lung cancer between May and September 2022. Patients were categorized based on PONV prevention methods, and data encompassing demographics, surgical history, and postoperative adverse events s were analyzed to assess the association between prophylactic protocols and PONV incidence. The Netupitant and Palonosetron Hydrochloride (NEPA) group showed a significant reduction in PONV occurrences post-surgery compared to Ondansetron (ONDA) and Control groups, emphasizing NEPA’s efficacy in alleviating PONV symptoms (P < 0.05). Furthermore, following VATS radical resection of lung cancer, NEPA markedly reduced the intensity of PONV symptoms in patients. Both univariate and multivariate logistic analyses corroborated that NEPA independently reduces PONV risk, with its protective effect also apparent in susceptible populations like females and non-smokers. NEPA utilization markedly reduced both the incidence and severity of PONV in patients undergoing VATS radical resection of lung cancer, serving as an independent protective factor in mitigating PONV risk post-surgery.

One-lung ventilation with fixed and variable tidal volumes on oxygenation and pulmonary outcomes: A randomized trial

ObjectiveTest the hypothesis that one-lung ventilation with variable tidal volume improves intraoperative oxygenation and reduces postoperative pulmonary complications after lung resection. BackgroundConstant tidal volume and respiratory rate ventilation can lead to atelectasis. Animal and human ARDS studies indicate that oxygenation improves with variable tidal volumes. Since one-lung ventilation shares characteristics with ARDS, we tested the hypothesis that one-lung ventilation with variable tidal volume improves intraoperative oxygenation and reduces postoperative pulmonary complications after lung resection. DesignRandomized trial. SettingOperating rooms and a post-anesthesia care unit. PatientsAdults having elective open or video-assisted thoracoscopic lung resection surgery with general anesthesia were randomly assigned to intraoperative ventilation with fixed (n = 70) or with variable (n = 70) tidal volumes. InterventionsPatients assigned to fixed ventilation had a tidal volume of 6 ml/kgPBW, whereas those assigned to variable ventilation had tidal volumes ranging from 6 ml/kg PBW ± 33% which varied randomly at 5-min intervals. MeasurementsThe primary outcome was intraoperative oxygenation; secondary outcomes were postoperative pulmonary complications, mortality within 90 days of surgery, heart rate, and SpO2/FiO2 ratio. ResultsData from 128 patients were analyzed with 65 assigned to fixed-tidal volume ventilation and 63 to variable-tidal volume ventilation. The time-weighted average PaO2 during one-lung ventilation was 176 (86) mmHg in patients ventilated with fixed-tidal volume and 147 (72) mmHg in the patients ventilated with variable-tidal volume, a difference that was statistically significant (p < 0.01) but less than our pre-defined clinically meaningful threshold of 50 mmHg. At least one composite complication occurred in 11 (17%) of patients ventilated with variable-tidal volume and in 17 (26%) of patients assigned to fixed-tidal volume ventilation, with a relative risk of 0.67 (95% CI 0.34–1.31, p = 0.24). Atelectasis in the ventilated lung was less common with variable-tidal volumes (4.7%) than fixed-tidal volumes (20%) in the initial three postoperative days, with a relative risk of 0.24 (95% CI 0.01–0.8, p = 0.02), but there were no significant late postoperative differences. No other secondary outcomes were both statistically significant and clinically meaningful. ConclusionOne-lung ventilation with variable tidal volume does not meaningfully improve intraoperative oxygenation, and does not reduce postoperative pulmonary complications.

Readmission after enhanced recovery video-assisted thoracoscopic surgery wedge resection

BackgroundDespite the implementation of Enhanced Recovery After Surgery (ERAS) programs, surgical stress continues to influence postoperative rehabilitation, including the period after discharge. However, there is a lack of data available beyond the point of discharge following video-assisted thoracoscopic surgery (VATS) wedge resection. Therefore, the objective of this study is to investigate incidence and risk factors for readmissions after ERAS VATS wedge resection.MethodsA retrospective analysis was performed on data from prospectively collected consecutive VATS wedge resections from June 2019 to June 2022. We evaluated main reasons related to wedge resection leading to 90-day readmission, early (occurring within 0–30 days postoperatively) and late readmission (occurring within 31–90 days postoperatively). To identify predictors for these readmissions, we utilized a logistic regression model for both univariable and multivariable analyses.ResultsA total of 850 patients (non-small cell lung cancer 21.5%, metastasis 44.7%, benign 31.9%, and other lung cancers 1.9%) were included for the final analysis. Median length of stay was 1 day (IQR 1–2). During the postoperative 90 days, 86 patients (10.1%) were readmitted mostly due to pneumonia and pneumothorax. Among the cohort, 66 patients (7.8%) had early readmissions primarily due to pneumothorax and pneumonia, while 27 patients (3.2%) experienced late readmissions mainly due to pneumonia, with 7 (0.8%) patients experiencing both early and late readmissions. Multivariable analysis demonstrated that male gender, pulmonary complications, and neurological complications were associated with readmission.ConclusionsReadmission after VATS wedge resection remains significant despite an optimal ERAS program, with pneumonia and pneumothorax as the dominant reasons. Early readmission was primarily associated with pneumothorax and pneumonia, while late readmission correlated mainly with pneumonia.

Multiple bronchial carcinoids associated with Cowden syndrome.

Cowden syndrome (CS) is a rare genetic condition due to the various germline mutations in the phosphatase and tensin homologue on chromosome ten (PTEN) tumour suppressor gene. As a result, CS is characterised by an increased risk of developing various benign and malignant tumours, such as thyroid, breast, endometrial and urogenital neoplasms, as well as gastrointestinal tract tumours. However, the neuroendocrine tumour association with CS is not elucidated yet. We present a case of a 46-year-old male patient diagnosed with testicular seminoma and follicular thyroid cancer in his medical history. Our patient met the clinical diagnostic criteria of Cowden syndrome. Genetic analysis established the clinical diagnosis; a known heterozygous PTEN mutation was detected [PTEN (LRG_311t1)c.388 C > T (p.Arg130Ter)]. Incidentally, he was also seen with multiple pulmonary lesions during his oncological follow-up. A video-assisted thoracoscopic left lingula wedge resection and later resections from the right lung were performed. Histological findings revealed typical pulmonary carcinoid tumours and smaller tumorlets. Somatostatin receptor SPECT-CT, 18F-FDG-PET-CT and 18F-FDOPA-PET-CT scans and endoscopy procedures could not identify any primary tumours in other locations. Our patient is the first published case of Cowden syndrome, associated with multifocal pulmonary carcinoids. Besides multiple endocrine neoplasia type 1, we propose Cowden syndrome as another hereditary condition predisposing to multiple pulmonary tumorlets and carcinoid tumours.

Modified surgical incision suturing technique in uniportal video-assisted thoracoscopic pulmonary resection.

In recent years, single-hole thoracoscopic surgery technology is widely used in major medical centers and chest-specialized hospitals for the treatment of lung diseases. However, the single-hole minimally invasive surgery method focuses on one incision, and all surgical instruments need to pass through the same hole, resulting in repeated extrusion and tissue damage of the surgical incision. Therefore, we have improved the suture method of conventional surgical incision in order to reduce the probability of wound infection and dehiscence, promote early healing, and reduce the severity of postoperative wound scar, thereby enhancing the postoperative rapid recovery of patients. The purpose of this study is to explore the clinical efficacy of a modified surgical incision suture technique applied to uniportal thoracoscopic pulmonary resection. This study retrospectively analyzed 151 patients who were admitted to the Department of Thoracic Surgery and underwent pulmonary resection from January 2019 to October 2021 in the North District of Suzhou Municipal Hospital. The patients were divided into two groups according to the different surgical incision suture methods: a modified group and a conventional group. The postoperative general clinical indexes, incision infection rate, secondary suture rate, postoperative incision pain score, and the severity of postoperative incision scar were compared and analyzed between the two groups. There were no statistically significant differences between the two groups in terms of chest tube duration or postoperative drainage and postoperative incision pain scores; the incision infection rate (1.3% vs. 6.7%, P<0.05), secondary suture rate (2.6% vs. 9.4%, P<0.05), and postoperative scar score (4.853 vs. 5.543, P=0.03) were better in the modified group than in the conventional group, and the differences between the two groups were statistically significant. Our modified suture method reduces the chance of infection and splitting and the severity of postoperative incision scar formation, promoting early healing. It can be safely and effectively applied to the incision suture of uniportal thoracoscopic pulmonary resection, enhancing the rapid postoperative recovery of patients.

Efficacy of avoiding chest drains after video-assisted thoracoscopic surgery wedge resection: protocol for a randomised controlled trial

IntroductionThe use of routine postoperative chest drains after video-assisted thoracoscopic surgery (VATS) of the lung is a practice based on tradition with the aim of draining fluid and air. However,...

Comparison of safety and anxiety/depression in computed tomography-guided hook-wire localization versus electromagnetic navigation bronchoscopy-guided localization: a retrospective cohort study.

The utilization of computed tomography (CT)-guided localization and electromagnetic navigation bronchoscopy (ENB)-guided localization has gained significant traction in the localization of pulmonary nodules before video-assisted thoracoscopic surgery (VATS). This study aimed to ascertain the precision and safety of the two groups in the preoperative resection of isolated nodules in small peripheral lungs. Furthermore, we examined the subsequent outcomes pertaining to the decline in lung function and alterations in anxiety and depression following resection utilizing both localization techniques. A total of 177 patients with small-sized pulmonary nodules, scheduled to undergo video-assisted thoracoscopic limited resection, were enrolled in this study. The study involved the examination and comparison of pertinent findings obtained through the utilization of CT-guided hook-wire or ENB injection techniques. The nodules were localized by ENB in 57 patients and by CT guidance in 120 patients. There were no significant complications in ENB-guided localization group (0/57). CT-guided hook-wire localization group had more complications (61/120, P<0.001). There was no disparity observed in pulmonary function decline 3 months post-operation between the two cohorts. The analysis of postoperative Hospital Anxiety and Depression Scale (HADS) scores indicated that the CT-guided localization group exhibited higher anxiety and depression scores on the initial day and 2 weeks following surgery. ENB-guided and CT-guided localization can effectively identify solitary pulmonary nodules. ENB-guided localization has fewer complications, lower incidence of adverse events, and less impact on postoperative anxiety or depression, suggesting that this is a promising, safe, and feasible method for localization of solitary pulmonary nodules.

Postoperative esketamine improves ventilation after video-assisted thoracoscopic lung resection: A double-blinded randomized controlled trial

BackgroundPain management after lung resection plays a crucial role in reducing postoperative pulmonary complications (PPCs). This study aimed to examine the effect of postoperative esketamine infusion as an adjunct to opioid analgesia on ventilation and pulmonary complications in patients underwent lung resection. MethodsPatients undergoing video-assisted thoracoscopic lung resection were randomly assigned to either the esketamine group or the control group. The esketamine group received a 24-h infusion of 1.5 mcg/ml sufentanil combined with 0.75 mcg/ml esketamine after surgery, while the control group received 1.5 mcg/ml sufentanil alone. The primary outcome measure was low minute ventilation, and the secondary outcome measures were hypoxemia, PaO2/FiO2 levels, postoperative pulmonary complications, hospital stay duration, ambulation time, Visual Analogue Scale (VAS) score, depression and anxiety levels, sleep quality, and analgesia satisfaction. Results80 patients were randomly divided into two groups: the esketamine group (n = 40) and the control group (n = 40). The esketamine group exhibited notably reduced incidence of low minute ventilation (P = 0.014), lower occurrence of postoperative pulmonary complications (PPCs) compared to the control group (P = 0.039), and decreased incidence of hypoxemia (P = 0.003). Furthermore, the esketamine group showed improved outcomes with lower VAS scores on the second postoperative day and enhanced sleep quality (P < 0.001) after the surgery. ConclusionsPostoperative esketamine infusion with opioids improved ventilation and reduced PPCs after lung resection, warranting further clinical studies. Trial registrationThis study was registered on ClinicalTrials.gov (Trial ID: NCT05458453, https://clinicaltrials.gov/ct2/show/NCT05458453).

Comparison between use of a pleural drainage system with flutter valve and a conventional water-seal drainage system after lung resection: a randomized prospective study.

There is still a debate regarding the most appropriate pleural collector model to ensure a short hospital stay and minimum complications. To study aimed to compare the time of air leak, time to drain removal, and length of hospital stay between a standard water-seal drainage system and a pleural collector system with a unidirectional flutter valve and rigid chamber. A randomized prospective clinical trial was conducted at a high-complexity hospital in São Paulo, Brazil. Sixty-three patients who underwent open or video-assisted thoracoscopic lung wedge resection or lobectomy were randomized into two groups, according to the drainage system used: the control group (WS), which used a conventional water-seal pleural collector, and the study group (V), which used a flutter valve device (Sinapi® Model XL1000®). Variables related to the drainage system, time of air leak, time to drain removal, and time spent in hospital were compared between the groups. Most patients (63%) had lung cancer. No differences were observed between the groups in the time of air leak or time spent hospitalized. The time to drain removal was slightly shorter in the V group; however, the difference was not statistically significant. Seven patients presented with surgery-related complications: five and two in the WS and V groups, respectively. Air leak, time to drain removal, and time spent in the hospital were similar between the groups. The system used in the V group resulted in no adverse events and was safe.

Safety and feasibility study of uniportal video-assisted thoracoscopic pulmonary wedge resection without postoperative chest tube drainage: a retrospective propensity score-matched study.

The aim of this study was to assess the impact of postoperative chest tube drainage (CTD) on safety and postoperative recovery by comparing patients with pulmonary nodule undergoing uniportal video-assisted thoracoscopic pulmonary wedge resection with and without postoperative CTD. We retrospectively analysed the data of patients who underwent video-assisted thoracoscopic pulmonary wedge resection for pulmonary nodule at our hospital between 2018 and 2022. In cases where a 12-Fr chest tube was used following the procedure, the tube was not usually removed until the day after surgery. Therefore, the eligible patients were categorized into the drainage tube or the no-drainage tube group according to the use of postoperative CTD. Propensity score matching at a ratio of 1:1 was performed using clinicopathologic and demographic variables. The highest postoperative pain score, postoperative complication rate, postoperative length of stay and hospitalization costs were compared between the 2 groups. A total of 275 eligible patients, including 150 and 125 patients in the drainage tube and no-drainage tube groups, respectively, were included in the study. After propensity score matching, there were 102 patients in each group. The postoperative complication rate during hospitalization and at 1 week and 1 month after discharge were not significantly different between the 2 groups (P > 0.05 for all). The highest postoperative pain score was significantly lower in the no-drainage tube group than in the drainage tube group [2.02 (standard deviation: 0.81) days vs 2.31 (standard deviation: 0.76) days, P = 0.008]. The postoperative length of stay was significantly shorter in the no-drainage tube group than in the drainage tube group {3.00 [interquartile ranges (IQRs): 2.00-4.00] days vs 2.00 (IQRs: 1.00-3.00) days, P < 0.001}. Similarly, the total hospitalization costs were significantly lower in the no-drainage tube group than in the drainage tube group [33283.74 (IQRs: 27098.61-46718.56) yuan vs 26598.67 (IQRs: 22965.14-29933.67) yuan, P < 0.001]. Omission of postoperative CTD was safe and feasible in patients with pulmonary nodule undergoing wedge resection. The no-postoperative-drainage policy can substantially shorten the length of hospital stay and reduce the postoperative pain and hospitalization costs without increasing the risk of postoperative complications.

Analgesic Effectiveness of Dinalbuphine Sebacate in Video-Assisted Thoracoscopic Wedge Resection and Its Effect on Reducing Postoperative Pulmonary Complications: A Retrospective Cohort Study.

Inadequate postoperative analgesia may cause postoperative complications, such as pulmonary complications. This study evaluated the analgesic effectiveness of a single preoperative injection of dinalbuphine sebacate (DS) in patients undergoing video-assisted thoracoscopic wedge resection and assessed whether it can reduce the incidence of postoperative pulmonary complications (PPCs). In this study, the data of 757 patients who underwent VATS wedge resection at a medical center were retrospectively reviewed. The patients were divided into the DS group and the conventional analgesia (CA) group. The following parameters were analyzed: analgesic consumption during hospitalization, the incidence of PPCs, and the postoperative use of oxygen therapy. Compared with the CA group, the DS group had lower nalbuphine, tramadol, parecoxib, acetaminophen, diclofenac, and utraphen consumption during the postoperative period; higher morphine and ketorolac consumption; and comparable fentanyl consumption. Nonetheless, the frequency of requesting pain relief was significantly lower in the DS group. No significant between-group differences were noted in the incidence of PPCs. However, the DS group had fewer requirements for oxygen therapy in the ward, early removal of chest tubes, and shorter length of hospital stay. A single preoperative injection of DS reduced the frequency of salvage analgesic administration and total consumption of certain postoperative analgesics, suggesting the effective pain relief of DS, and it did not increase the incidence of PPCs. Additionally, it reduced the need for postoperative oxygen therapy, which may suggest a better prognosis and smoother postoperative pulmonary recovery for patients.

Radiological Features of Changes in the Lungs Caused by Fast- or Slow-Growing Nontuberculous Mycobacteria

Objective: to compare radiological features of pulmonary nontuberculous mycobacterioses (NTM) caused by fast- or slow-growing mycobacteria.Material and methods. Radiological features of the disease were studied in 110 patients with newly diagnosed NTM. The patients were divided into two groups: 70 (63.6%) patients with slow-growing NTM and 40 (36.3%) with fast-growing NTM. The diagnosis was based on patient’s complaints, specified case history, radiological studies, clinical laboratory studies, sputum smear studies, bronchoalveolar lavage studies, different types of bronchial biopsies, and video-assisted thoracoscopic surgery resection samples. According to the results of high-resolution computed tomography (HRCT), a comparative analysis of the degree of involvement in the pathological process of such anatomical formations as parenchyma and stroma, vessels, bronchi, pleura and intrathoracic lymph nodes was carried out.Results. The analysis of HRCT studies showed that fast-growing NTM is not characterized by gross deformation of bronchopulmonary structures. There is a more pronounced infiltrative phase with the involvement of vessels, pleura and bronchial lesions of smaller generations, the formation of broncho-bronchiolectasias and symptoms of bronchiolitis, faster clinical and radiological involution under dynamic observation. Slow-growing NTM is characterized by a more severe deformation of bronchopulmonary structures with the formation of different-sized bronchiectasis, bronchogenic cavities, a more torpid course of the inflammatory process.Conclusion. Despite the similarities of clinical and radiological patterns of NTM, we established some distinguished features for slow-growing and fast-growing types.

Days alive and out of hospital after video-assisted thoracoscopic surgery wedge resection in the era of enhanced recovery.

Days alive and out of hospital is proposed as a valid and patient-centred quality measure for perioperative care. However, no procedure-specific data exist after pulmonary wedge resection. The aim of this study was to assess the first 90 days alive and out of hospital after video-assisted thoracoscopic surgery wedge resection in an optimized enhanced recovery programme. A retrospective analysis of prospectively collected data of consecutive patients undergoing enhanced recovery thoracoscopic wedge resections from January 2021 to June 2022 in a high-volume centre was carried out. All factors leading to hospitalization, readmission, and death were evaluated individually. A logistic regression model was used to evaluate predictors. Additionally, a sensitivity analysis was performed. A total of 433 patients were included (21.7% (n = 94) with non-small cell lung cancer, 47.6% (n = 206) with metastasis, 26.8% (n = 116) with benign nodules, and 3.9% (n = 17) with other lung cancers). The median duration of hospital stay was 1 day. The median of postoperative 30 and 90 days alive and out of hospital was 28 and 88 days respectively. Air leak (112 patients) and pain (96 patients) were the most frequent reasons for reduced days alive and out of hospital from postoperative day 1 to 30, whereas treatment of the original cancer or metastasis (36 patients) was the most frequent reason for reduced days alive and out of hospital from postoperative day 31 to 90. Male sex, reduced lung function, longer dimension of resection margin, pleural adhesions, and non-small cell lung cancer were independent risks, confirmed by a sensitivity analysis. Days alive and out of hospital within 90 days after enhanced recovery thoracoscopic wedge resection was only reduced by a median of 2 days, mainly due to air leak and pain.

Comparing Continuous and Intermittent Infusion Effects on Serratus Anterior Plane Blocks in Video-Assisted Thoracoscopic Surgery: A Randomized Clinical Trial.

The programmed intermittent bolus infusion (PIBI) of local anesthetic produces wider sensory blockade and better analgesia than continuous infusion (CI). We designed this trial to compare the effects of these two different infusion methods combined with Serratus Anterior Plane Blocks (cSAPBs) on postoperative pain relief in patients undergoing video-assisted thoracoscopic surgery. We randomly allocated 66 patients under going elective video-assisted thoracoscopic unilateral lung resection surgery to two groups (PIBI group and CI group, n=33 per group). After the surgical operation, the patients received ultrasound-guided ipsilateral SAPB, we randomized them to receive either automated intermittent boluses or continuous infusion of 0.3% ropivacaine. Tramadol consumption during the 48 hours following surgery was the primary outcome. Secondary outcomes included cumulative tramadol consumption during the first 24-h and the second 24-h periods after surgery, pain scores, patient satisfaction, blocked dermatomes, and adverse events. During 48h, tramadol consumption in the PIBI group was significantly lower than in the CI group (190 mg [125, 305] vs 220 mg [170, 480], p= 0.034). As compared to the CI group, the PIBI group consumed less tramadol during the first 24 hours (145 mg [87.5, 210] vs 190 mg [140, 400], p=0.012). The dermatomes anesthetized to the pinprick and cold test were significantly more abundant in the PIBI group than in the CI group (3 [3,4] vs. 5 [4,5], p<0.001). Both groups had similar VAS scores at rest and when moving (p>0.05). Additionally, the PIBI group showed greater patient satisfaction. Both groups experienced similar adverse events (p>0.05). Compared with CI, PIBI administration regimen (0.3% ropivacaine 5 mL/h) for cSAPBs resulted in lower tramadol consumption, superior analgesia during the initial 12 h after the operation, and higher patient satisfaction. PIBI combined with cSAPBs was a better choice for postoperative analgesia in patients undergoing video-assisted thoracoscopic surgery.

Postoperative morbidity after anatomical lung resections by VATS vs thoracotomy: Treatment and intention-to-treat analysis of the Spanish Video-Assisted Thoracic Surgery Group

ObjectivesIn recent years, video-assisted thoracoscopic lung resections (VATS) have been associated with lower morbidity than open surgery. The aim of our study is to compare postoperative morbidity among patients from the national database of the Spanish Group of Video-Assisted Thoracic Surgery (GE-VATS) after open and video-assisted anatomic lung resections using a propensity score analysis. MethodsFrom December 2016 to March 2018, a total of 3533 patients underwent anatomical lung resection at 33 centers. Pneumonectomies and extended resections were excluded. A propensity score analysis was performed to compare the morbidity of the thoracotomy group (TG) vs the VATS group (VATSG). Treatment and intention-to-treat (ITT) analyses were conducted. ResultsIn total, 2981 patients were finally included in the study: 1092 (37%) in the TG and 1889 (63%) in the VATSG for the treatment analysis; and 816 (27.4%) in the TG and 2165 patients (72.6%) in the VATSG for the ITT analysis. After propensity score matching, in the treatment analysis, the VATSG was significantly associated with fewer overall complications than the TG OR 0.680 [95%CI 0.616, 0.750]), fewer respiratory (OR 0.571 [0.529, 0.616]) cardiovascular (OR 0.529 [0.478, 0.609]) and surgical (OR 0.875 [0.802, 0.955]) complications, lower readmission rate (OR 0.669 [0.578, 0.775]) and a reduction of hospital length of stay (−1.741 ([−2.073, −1.410]). Intention-to-treat analysis showed only statistically significant differences in overall complications (OR 0.76 [0.54–0.99]) in favor of the VATSG. ConclusionIn this multicenter population, VATS anatomical lung resections have been associated with lower morbidity than those performed by thoracotomy. However, when an intention-to-treat analysis was performed, the benefits of the VATS approach were less prominent.

Evaluation of Thoracoscopic Lobectomy in Infants for Congenital Lung Lesions: Earlier Is Better!

ObjectivesThis study evaluates the safety and efficacy of thoracoscopic lobectomy for congenital lung lesions in infants less then 4 months of age. Materials and methodsFrom January 1997 to October 2022, 194 patients under 4 months of age and weight less then 5.6 Kg underwent video-assisted thoracoscopic lobe resection for CPAM, Sequestration, and CLE. All procedures were performed by or under the direct guidance of a single surgeon. Results195 of 196 procedures were completed thoracoscopically. Operative times ranged from 25 min to 195 min (average, 82 min). There were 50 upper, 8 middle, and 136 lower lobe resections. There were 4 intraoperative complications (2.1 %), of which 1 (0.5 %) required conversion to an open thoracotomy. The postoperative complication rate was 3.1 % Hospital length of stay ranged from 1 to 8 days (Avg 1.8) for those admitted for surgery. There were no conversions to open or blood transfusions in the last 15 years. ConclusionsThoracoscopic lung resection congenital lung lesions in infants is a safe and efficacious technique and avoids the morbidity of a thoracotomy. Early intervention allows surgery before clinical infections or symptoms occur. Newer instrumentation and techniques allow the operation to be safely performed in the first few months of life with shorter operative times, fewer complications, and decreased hospital stays. The minimal morbidity of this procedure should be considered when considering non-operative management of these patients. Level of Evidence3.

A novel, simple near-infrared thoracoscopic technique by a particular route for locating lung nodules.

The localization of pulmonary nodules prior to thoracoscopic surgery remains challenging for thoracic surgeons, especially for those nodules that are not visible or palpable on the lung surface. Our study is a simple and effective minimally invasive method using indocyanine green through a special pathway to locate pulmonary nodules and fluorescence thoracoscopic surgery. Thoracoscopic surgery was performed for 18 undiagnosed peripheral non-solid nodules no larger than 2 cm after location. After 0.3 mg/kg indocyanine green was injected through the peripheral vein, the puncture needle was pulled out after it reached approximately 1 cm of the pulmonary parenchyma near the nodules. This was followed by transfer to the operating room. The nodule was initially localized by using a near-infrared thoracoscope to visualize indocyanine green fluorescence. Then, thoracoscopic resection was performed. Eighteen patients received this special and simple localization method, and underwent near-infrared, image-guided, video-assisted thoracoscopic surgery resection. Median computed tomography (CT) tumor size was 1.2 cm. Median depth from the pleural surface is 1.6 cm (range, 0.1-4.6 cm). The median time of CT-guided intervention was 12 min. The duration of thoracoscopic surgery was 67 min. Indocyanine green fluorescence was clearly identified in 17 of 18 patients (94.4%). The surgical margins were all negative on final pathology. The final diagnoses included 17 primary lung cancers, and 1 benign lung tumor. CT-guided single puncture of indocyanine green after peripheral intravenous injection is a simple, effective, and safe method to locate the nodule. This offers surgeons the ease of localization through direct indocyanine green fluorescence imaging, and it can be used as an effective alternative to other placement methods of locating pulmonary nodules.

Percutaneous Computed Tomography (CT)-Guided Localization with Indocyanine Green for the Thoracoscopic Resection of Small Pulmonary Nodules.

The identification of small lung nodules is challenging during mini-invasive thoracic surgery. Unable to palpate them directly, surgeons have developed several methods to preoperatively localize pulmonary nodules, including the computed tomography-guided positioning of coils or metallic landmarks (hook wire) or bronchoscopic marking. We present a series of patients scheduled for the video-assisted thoracoscopic sublobar resection of small pulmonary nodules, in which we performed preoperative percutaneous computed tomography (CT)-guided nodule localization through the injection of a mixture of indocyanine green and human albumin. A total of 40 patients underwent a preoperative CT-guided injection of indocyanine green followed by VATS resection within 24 h. Patients tolerated the procedure well, no pain medication was administrated, and no complications were observed during the marking procedure. All pulmonary nodules were easily detected and successfully resected. the near-infrared dye marking solution of indocyanine green (ICG) with diluted human albumin was safe, effective, and easy to perform. The ICG solution has the potential to facilitate the accurate localization and resection of pulmonary nodules during VATS surgery, avoiding the risk of marker displacement/migration.

Postoperative morbidity after anatomical lung resections by VATS vs thoracotomy: Treatment and intention-to-treat analysis of the Spanish Video-Assisted Thoracic Surgery Group

ObjectivesIn recent years, video-assisted thoracoscopic lung resections (VATS) have been associated with lower morbidity than open surgery. The aim of our study is to compare postoperative morbidity among patients from the national database of the Spanish Group of Video-Assisted Thoracic Surgery (GE-VATS) after open and video-assisted anatomic lung resections using a propensity score analysis. MethodsFrom December 2016 to March 2018, a total of 3533 patients underwent anatomical lung resection at 33 centers. Pneumonectomies and extended resections were excluded. A propensity score analysis was performed to compare the morbidity of the thoracotomy group (TG) vs the VATS group (VATSG). Treatment and intention-to-treat (ITT) analyses were conducted. ResultsIn total, 2981 patients were finally included in the study: 1092 (37%) in the TG and 1889 (63%) in the VATSG for the treatment analysis; and 816 (27.4%) in the TG and 2165 patients (72.6%) in the VATSG for the ITT analysis. After propensity score matching, in the treatment analysis, the VATSG was significantly associated with fewer overall complications than the TG OR 0.680 [95%CI 0.616, 0.750]), fewer respiratory (OR 0.571 [0.529, 0.616]) cardiovascular (OR 0.529 [0.478, 0.609]) and surgical (OR 0.875 [0.802, 0.955]) complications, lower readmission rate (OR 0.669 [0.578, 0.775]) and a reduction of hospital length of stay (−1.741 ([−2.073, −1.410]). Intention-to-treat analysis showed only statistically significant differences in overall complications (OR 0.76 [0.54–0.99]) in favor of the VATSG. ConclusionIn this multicenter population, VATS anatomical lung resections have been associated with lower morbidity than those performed by thoracotomy. However, when an intention-to-treat analysis was performed, the benefits of the VATS approach were less prominent.
