ABSTRACT
BACKGROUND: Kirschner wires are widely used in trauma surgery. Their migration into the pericardium is a rare but often fatal phenomenon, requiring urgent management. CASE PRESENTATION: We describe the case of a 65-year-old patient who underwent Kirschner wire placement to treat a humeral head fracture. Three months after the operation, pleural and pericardial effusions with cardiac tamponade were observed, leading to the diagnosis of wire migration within the pericardium. A minimally invasive approach guided by fluoroscopy allowed emergency wire extraction without needing a median sternotomy. The postoperative clinical course was uncomplicated. CONCLUSIONS: The use of pre- and per-operative multimodal imaging allowed for the safe extraction of an intra-pericardial Kirschner wire through a minimally invasive approach.
ABSTRACT
OBJECTIVES: Serratus anterior plane block (SAPB) and paravertebral block (PVB) are well known to reduce pain levels after video-assisted thoracoscopic surgery (VATS). However, the relative efficacies of each block and a combination of the 2 have not been fully characterized. The objective of the present study was to assess the efficacy of PVB alone, SAPB alone and the combination of PVB and SAPB with regard to the occurrence and intensity of pain after VATS. METHODS: We conducted the THORACOSOPIC single-centre, double-blind, randomized trial in adult patients due to undergo elective VATS lung resection. The participants were randomized to PVB only, SAPB only and PVB + SAPB groups. The primary end-point was pain on coughing on admission to the postanaesthesia care unit. The secondary end-points were postoperative pain at rest and on coughing at other time points and the cumulative opioid consumption. Pain was scored on a visual analogue scale. RESULTS: One-hundred and fifty-six patients (52 in each group) were included. On admission to the postanaesthesia care unit, the 3 groups did not differ significantly with regard to the pain on coughing: the visual analogue scale score was 3 (0-6), 4 (0-8) and 2 (0-6) in the PVB, SAPB and PVB + SAPB groups, respectively (P = 0.204). During postoperative care, the overall pain score was significantly lower in the SABP + PVP group at rest and on cough. CONCLUSIONS: The combination of SABP + PVB could be beneficial for pain management in VATS in comparison to SABP or PVB alone.

OBJECTIVES: Intraoperative bacterial airway colonization seems to be associated with an increased risk of postoperative pneumonia (POP). It can be easily assessed by performing a bronchial aspirate (BA). The objective of this study is to assess the diagnostic performance of the BA to predict POP. METHODS: We conducted a single-centre retrospective observational study over a period of 10 years, from 1 January 2011 to 30 December 2020. The population study included patients admitted for a scheduled pulmonary resection surgery for lung cancer. Patients were classified into 2 populations depending on whether or not they developed a POP. Uni- and multivariable analyses were performed to identify risk factors for developing POP. The diagnostic performance of BA was represented by its sensitivity, specificity and positive and negative predictive values. RESULTS: A total of 1006 patients were included in the study. Uni- and multivariable analyses found that a positive BA was independently associated with a greater risk of developing POP with an odds ratio of 6.57 [4.165-10.865]; P < 0.001. Its specificity was 95%, sensitivity was 31%, positive predictive value was 66% and negative predictive value was 81%. CONCLUSIONS: A positive intraoperative BA is an independent risk factor for POP after lung cancer surgery. Further trials are required to validate the systematic implementation of BA as an early diagnostic tool for POP.
ABSTRACT
Clinical presentation and mortality of patients treated with extracorporeal membrane oxygenation (ECMO) for COVID-19 acute respiratory distress syndrome (CARDS) were different during the French epidemic waves. The management of COVID-19 patients evolved through waves as much as knowledge on that new viral disease progressed. We aimed to compare the mortality rate through the first three waves of CARDS patients on ECMO and identify associated risk factors. Fifty-four consecutive ECMO for CARDS hospitalized at Amiens University Hospital during the three waves were included. Patients were divided into three groups according to their hospitalization date. Clinical characteristics and outcomes were compared between groups. Pre-ECMO risk factors predicting 90 day mortality were evaluated using multivariate Cox regression. Among 54 ECMO (median age of 61[48-65] years), 26% were hospitalized during the first wave (n = 14/54), 26% (n = 14/54) during the second wave, and 48% (n = 26/54) during the third wave. Time from first symptoms to ECMO was higher during the second wave than the first wave. (17 [12-23] days vs. 11 [9-15]; p < 0.05). Ninety day mortality was higher during the second wave (85% vs. 43%; p < 0.05) but less during the third wave (38% vs. 85%; P < 0.05). Respiratory ECMO survival prediction score and time from symptoms onset to ECMO (HR 1.12; 95% confidence interval [CI]: 1.05-1.20; p < 0.001) were independent factors of mortality. After adjustment, time from symptoms onset to ECMO was an independent factor of 90 day mortality. Changes in CARDS management from first to second wave-induced a later ECMO cannulation from symptoms onset with higher mortality during that wave. The duration of COVID-19 disease progression could be selection criteria for initiating ECMO.

BACKGROUND: Patients treated surgically for lung cancer may present synchronous or metachronous lung cancers. The aim of this study was to evaluate outcomes after a second contralateral anatomic surgical resection for lung cancer. METHODS: We performed a retrospective two-center study, based on a prospective indexed database. Included patients were treated surgically by bilateral anatomic surgical resection for a second primary lung cancer. We excluded nonanatomic resections, benign lesions, and ipsilateral second surgical resections. RESULTS: Between January 2011 and September 2018, 55 patients underwent contralateral anatomic surgical resections for lung cancer, mostly for metachronous cancers. The first surgical resection was a lobectomy in most cases (45 lobectomies: 81.8%, 9 segmentectomies: 16.4%, and 1 bilobectomy: 1.8%), and a video-assisted thoracic surgery (VATS) procedure was used in 23 cases (41.8%). The mean interval between the operations was 38 months, and lobectomy was less frequent for the second surgical resection (35 lobectomies: 63.6% and 20 segmentectomies: 36.4%), with VATS procedures performed in 41 cases (74.5%). Ninety-day mortality was 10.9% (n = 6), and 3-year survival was 77%. Risk factor analysis identified the number of resected segments during the second intervention or the total number of resected segments, extent of resection (lobectomy vs. segmentectomy), surgical approach (thoracotomy vs. VATS), tumor stage, and nodal involvement as potential prognostic factors for long-term survival. CONCLUSION: A second contralateral anatomic surgical resection for multiple primary lung cancer is possible, with a higher early mortality rate, but acceptable long-term survival, and should be indicated for carefully selected patients.

OBJECTIVES: Intraoperative conversion may be required during video-assisted thoracoscopic surgery (VATS) for lung cancer. We evaluated the morbidity and mortality rates associated with VATS for anatomical pulmonary resection with conversion to thoracotomy and compared this technique with full VATS and an open thoracotomic approach. METHODS: We performed a retrospective, single-centre study between January 2011 and January 2017 and included 610 consecutive patients having undergone either VATS (with or without intraoperative conversion) or open thoracotomy for anatomical pulmonary resection. Pneumonectomies and angioplastic/bronchoplastic/chest wall resections were excluded. After propensity score adjustment, we assessed the 90-day mortality and determined whether the surgical approach was a risk factor for mortality. RESULTS: Of the 610 patients, 253 patients underwent full VATS, 56 patients underwent VATS + conversion and 301 patients underwent up-front open thoracotomy. Relative to the open thoracotomy group, the VATS + conversion group had a higher incidence of cardiac or respiratory comorbidities and was more likely to have an early-stage tumour. Following adjustment, the 90-day postoperative mortality rate was 5.4% (n = 3/56) in the VATS + conversion group and 3.7% (n = 11/301) in the open thoracotomy group (P = 0.58). Likewise, the morbidity rate was similar in these 2 groups. In a multivariable analysis, the surgical approach was not a risk factor for postoperative mortality. CONCLUSIONS: Following anatomical resection for lung cancer, VATS with conversion and open thoracotomy were associated with similar early postoperative morbidity and mortality rates. When in doubt, VATS should be preferred to thoracotomy; it potentially provides the patient with benefits of a fully VATS-based resection but is not disadvantageous when intraoperative conversion is required.

PURPOSE: Anatomic variations of the pulmonary arterial tree can cause technical difficulties during pulmonary lobectomy in general and video-assisted thoracic surgery (VATS). Using CT angiography and 3D reconstruction, we sought to identify anatomic variations of the pulmonary arterial tree and assess their respective frequencies. METHODS: We retrospectively studied 88 pulmonary arterial trees in 44 patients having undergone VATS lobectomy for lung cancer over an 18-month period in Amiens University Hospital's Department of Thoracic Surgery. Each CT angiography with 3D reconstruction of the pulmonary arterial tree was performed by two experienced operators, according to a standardized procedure. RESULTS: On the right side, the upper lobe was supplied with blood by a mediastinal artery in 100% of cases and by one or more fissural arteries in 88.6%. The middle lobe was usually supplied by two arteries (54.5%). The upper segment of the right lower lobe was usually supplied by a single artery (90.9%). We identified 11 variations in the vasculature of the basal segments. On the left side, the upper lobe was supplied by four arteries in 50% of cases, three culminal arteries (50%), and a fissural lingular artery (77.3%). The upper segment of the left lower lobe was usually supplied by a single artery (65.9%). We identified 15 anatomic variations in the vasculature of the basal segments. We observed that the origin of the apical artery of the right lower lobe was proximal to the origin of the middle lobe artery in 38.6% of cases. The origin of the apical artery of the left lower lobe artery was proximal to the origin of the lingular fissural artery in 65.9% of cases. CONCLUSION: The findings of the present CT angiography/3D reconstruction study agreed with the reference works on the anatomy of the pulmonary arterial tree and defined the frequency of anatomic variations. It is essential to assess the anatomy of the pulmonary arterial tree before VATS lobectomy.

PURPOSE: Although peribronchial lymphatic drainage of the lung has been well characterized, lymphatic drainage in the visceral pleura is less well understood. The objective of the present study was to evaluate the lymphatic drainage of lung segments in the visceral pleura. METHODS: Adult, European cadavers were examined. Cadavers with a history of pleural or pulmonary disease were excluded. The cadavers had been refrigerated but not embalmed. The lungs were surgically removed and re-warmed. Blue dye was injected into the subpleural area and into the first draining visceral pleural lymphatic vessel of each lung segment. RESULTS: Twenty-one cadavers (7 males and 14 females; mean age 80.9 years) were dissected an average of 9.8 day postmortem. A total of 380 dye injections (in 95 lobes) were performed. Lymphatic drainage of the visceral pleura followed a segmental pathway in 44.2% of the injections (n = 168) and an intersegmental pathway in 55.8% (n = 212). Drainage was found to be both intersegmental and interlobar in 2.6% of the injections (n = 10). Lymphatic drainage in the visceral pleura followed an intersegmental pathway in 22.8% (n = 13) of right upper lobe injections, 57.9% (n = 22) of right middle lobe injections, 83.3% (n = 75) of right lower lobe injections, 21% (n = 21) of left upper lobe injections, and 85.3% (n = 81) of left lower lobe injections. CONCLUSION: In the lung, lymphatic drainage in the visceral pleura appears to be more intersegmental than the peribronchial pathway is-especially in the lower lobes. The involvement of intersegmental lymphatic drainage in the visceral pleura should now be evaluated during pulmonary resections (and especially sub-lobar resections) for lung cancer.

BACKGROUND AND OBJECTIVE: Laryngeal pathology following lung cancer surgery is associated with post-operative morbidity and mortality. The aim of our study was to evaluate the usefulness of routine endoscopic assessment. METHODS: We prospectively evaluated vocal cord pathology using laryngeal endoscopy within 24 h post-surgery. Over 25 months, 276 patients underwent thoracic surgery. We excluded 26 patients with previous laryngectomy or vocal cord paralysis, early post-operative reintubation or patients who did not consent to an endoscopy. Endoscopic data were reported using a standardized procedure, recording vocal cord paralysis, swallowing disorders with aspiration, detected using a blue-coloured water test and vocal cord haematoma. RESULTS: Among 250 patients, vocal cord paralysis was diagnosed in 13 patients (5.2%) and was associated with a higher rate of post-operative pneumonia (P = 0.03), post-operative bronchoscopy (P = 0.01), reintubation (P = 0.007) and a trend towards an increased 90-day mortality rate (P = 0.09). Swallowing disorders with aspiration were diagnosed in 18 patients (7.2%) and were associated with a higher rate of post-operative pneumonia (P = 0.007), post-operative bronchoscopy (P = 0.01), reintubation (P = 0.004) and 90-day mortality (P = 0.03). Vocal cord haematomas were diagnosed in 28 patients (11.2%) and were not associated with an increased post-operative morbidity or mortality. CONCLUSION: Post-operative endoscopic laryngeal assessment is effective for diagnosing laryngeal pathology following thoracic surgery. Routine laryngeal endoscopic assessment may detect clinically silent swallowing disorders early to allow prompt treatment, which may prevent respiratory complications.

BACKGROUND: Predicted postoperative FEV1 (ppoFEV1) must be estimated preoperatively prior to surgery for non-small cell lung cancer (NSCLC). We evaluated a lung volumetry approach based on chest computed tomography (CT). METHODS: A prospective study was conducted over a period of one year in eligible lung cancer patients to evaluate the difference between ppoFEV1 and the 3-month postoperative FEV1 (poFEV1). Patients in whom CT was performed in another hospital and those with factors influencing poFEV1, such as atelectasis, pleural effusion, pneumothorax, or pneumonia, were excluded. A total of 23 patients were included and ppoFEV1 was calculated according to 4 usual Methods: Nakahara formula, Juhl and Frost formula, ventilation scintigraphy, perfusion scintigraphy, and a fifth method based on quantitative CT. Lung volume was calculated twice and separately by 2 radiologists. Tumor volume, and emphysema defined by a -950 HU limit were subtracted from the total lung volume in order to estimate ppoFEV1. RESULTS: We compared 5 methods of ppoFEV1 estimation and calculated the mean volume difference between ppoFEV1 and poFEV1. A better correlation was observed for quantitative CT than for Nakahara formula, Juhl and Frost formula, perfusion scintigraphy and ventilation scintigraphy with respectively: R2=0.79 vs. 0.75, 0.75, 0.67 and 0.64 with a mean volume difference of 266±229 mL (P<0.01) vs. 320±262 mL (P<0.01), 332±251 mL (P<0.01), 304±295 mL (P<0.01) and 312±303 mL (P<0.01). CONCLUSIONS: Quantitative CT appears to be a satisfactory method to evaluate ppoFEV1 evaluation method, and appears to be more reliable than other approaches. Estimation of ppoFEV1, as part of the preoperative assessment, does not involve additional morphologic examinations, particularly scintigraphy. This method may become the reference method for ppoFEV1 evaluation.

ABSTRACT
OBJECTIVE: Despite recent advances in imaging and core or endoscopic biopsies, a percentage of patients have a major lung resection without diagnosis. We aimed to assess the feasibility of a rapid tissue preparation/analysis to discriminate cancerous from non-cancerous lung tissue. METHODS: Fresh sample preparations were analyzed with the Microflex LTTM MALDI-TOF analyzer. Each main reference spectra (MSP) was consecutively included in a database. After definitive pathological diagnosis, each MSP was labeled as either cancerous or non-cancerous (normal, inflammatory, infectious nodules). A strategy was constructed based on the number of concordant responses of a mass spectrometry scoring algorithm. A 3-step evaluation included an internal and blind validation of a preliminary database (n = 182 reference spectra from the 100 first patients), followed by validation on a whole cohort database (n = 300 reference spectra from 159 patients). Diagnostic performance indicators were calculated. RESULTS: 127 cancerous and 173 non-cancerous samples (144 peripheral biopsies and 29 inflammatory or infectious lesions) were processed within 30 minutes after biopsy sampling. At the most discriminatory level, the samples were correctly classified with a sensitivity, specificity and global accuracy of 92.1%, 97.1% and 95%, respectively. CONCLUSIONS: The feasibility of rapid MALDI-TOF analysis, coupled with a very simple lung preparation procedure, appears promising and should be tested in several surgical settings where rapid on-site evaluation of abnormal tissue is required. In the operating room, it appears promising in case of tumors with an uncertain preoperative diagnosis and should be tested as a complementary approach to frozen-biopsy analysis.

OBJECTIVES: Common video systems for video-assisted thoracic surgery (VATS) provide the surgeon a two-dimensional (2D) image. This study aimed to evaluate performances of a new three-dimensional high definition (3D-HD) system in comparison with a two-dimensional high definition (2D-HD) system when conducting a complete thoracoscopic lobectomy (CTL). METHODS: This multi-institutional comparative study trialled two video systems: 2D-HD and 3D-HD video systems used to conduct the same type of CTL. The inclusion criteria were T1N0M0 non-small-cell lung carcinoma (NSCLC) in the left lower lobe and suitable for thoracoscopic resection. The CTL was performed by the same surgeon using either a 3D-HD or 2D-HD system. Eighteen patients with NSCLC were included in the study between January and December 2013: 14 males, 4 females, with a median age of 65.6 years (range: 49-81). The patients were randomized before inclusion into two groups: to undergo surgery with the use of a 2D-HD or 3D-HD system. We compared operating time, the drainage duration, hospital stay and the N upstaging rate from the definitive histology. RESULTS: The use of the 3D-HD system significantly reduced the surgical time (by 17%). However, chest-tube drainage, hospital stay, the number of lymph-node stations and upstaging were similar in both groups. CONCLUSIONS: The main finding was that 3D-HD system significantly reduced the surgical time needed to complete the lobectomy. Thus, future integration of 3D-HD systems should improve thoracoscopic surgery, and enable more complex resections to be performed. It will also help advance the field of endoscopically assisted surgery.

Recently, tissue-based methods for proteomic analysis have been used in clinical research and appear reliable for digestive, brain, lymphomatous, and lung cancers classification. However simple, tissue-based methods that couple signal analysis to tissue imaging are time consuming. To assess the reliability of a method involving rapid tissue preparation and analysis to discriminate cancerous from non-cancerous tissues, we tested 141 lung cancer/non-tumor pairs and 8 unique lung cancer samples among the stored frozen samples of 138 patients operated on during 2012. Samples were crushed in water, and 1.5 µl was spotted onto a steel target for analysis with the Microflex LT analyzer (Bruker Daltonics). Spectra were analyzed using ClinProTools software. A set of samples was used to generate a random classification model on the basis of a list of discriminant peaks sorted with the k-nearest neighbor genetic algorithm. The rest of the samples (nâ=â43 cancerous and nâ=â41 non-tumoral) was used to verify the classification capability and calculate the diagnostic performance indices relative to the histological diagnosis. The analysis found 53 m/z valid peaks, 40 of which were significantly different between cancerous and non-tumoral samples. The selected genetic algorithm model identified 20 potential peaks from the training set and had 98.81% recognition capability and 89.17% positive predictive value. In the blinded set, this method accurately discriminated the two classes with a sensitivity of 86.7% and a specificity of 95.1% for the cancer tissues and a sensitivity of 87.8% and a specificity of 95.3% for the non-tumor tissues. The second model generated to discriminate primary lung cancer from metastases was of lower quality. The reliability of MALDI-ToF analysis coupled with a very simple lung preparation procedure appears promising and should be tested in the operating room on fresh samples coupled with the pathological examination.

BACKGROUND: The influence of nutritional status on outcome after major lung resection remains controversial. Nutritional assessment is not included as a major recommendation in lung cancer guidelines. The purpose of this study was to assess the nutritional status of patients referred for pneumonectomy and to assess the predictive value of malnutrition in determining the surgical outcome. METHODS: This study was a multicenter observational trial. The eligibility criterion for participants was pneumonectomy for lung cancer. Criteria for group classification according to nutritional status were albumin and transthyretin levels. Predicted outcomes were major infectious and noninfectious complications and 90-day mortality. Univariate analysis identified independent variables for the predictive model of age, sex, induction chemotherapy, extended resections, treatment side, smoking, and malnutrition. Predictive variables were then included in a logistic regression model. RESULTS: Between January 2010 and December 2011, 86 (mean age, 61.5 years) consecutive patients referred for pneumonectomy (left side, n = 58; right side, n = 28) at 4 thoracic surgery centers were included. The malnutrition group included 33 patients (39%) and the normal nutritional status group included 53 patients. Univariate analysis elected malnutrition, recent active smoking, and extended resection to be included in a multivariate analysis. Multivariate analysis identified malnutrition, recent smoking, and extended resection as predictive variables for major complications and mortality. CONCLUSIONS: The frequency of malnutrition detected by biological markers was dramatically high. Malnutrition, as well as recent active smoking and extended resection, is a predictive factor for infectious complications and mortality after pneumonectomy. Nutritional assessment with appropriate markers should be considered before pneumonectomy.

False aortic aneurysm is an uncommon complication after oesophageal perforation and results in a high rate of mortality. A 63-year-old patient presented with acute chest pain. Biochemical tests (cardiac enzymes) and electrocardiogram were normal. A thoracic and abdominal CT scan was performed, and showed a foreign body in the posterior mediastinum, with mediastinal cellulitis and a false aortic aneurysm. Surgical endovascular management was performed, with stenting of the thoracic aorta and oesophageal exploration.

The thoracodorsal artery perforator flap (TDAP flap) allows raising the same cutaneous island as in the classical latissimus dorsi musculocutaneous flap without its muscular part. All patients who underwent a completion pneumonectomy with reinforcement of bronchial stump with a TDAP flap from December 2009 to October 2010 were followed prospectively. The 30-day mortality and the procedure-related morbidity as well as bronchial fistula and TDAP flap were analyzed. The TDAP flap was used in 6 cases without failure or fistula formation. At 1 month, all patients were alive, and there was no morbidity (seroma, hematoma, fistula, or shoulder dysfunction). Computed tomography scans were performed at 1 month and 3 months postoperatively and showed viable nonatrophic flap. This type of flap has been described in the field of plastic surgery, and this is the first description of its use in the chest. Deepithelialized fasciocutaneous TDAP flap is safe and reliable. It is available even if the latissimus dorsi has been previously divided. It is now our first-line option to reinforce the bronchial stump.

UNLABELLED: OBJECTIVES; Patients with extrathoracic synchronous solitary metastasis and non-small cell lung cancer (NSCLC) are rare. The effectiveness of both tumour sites resection is difficult to evaluate because of the high variability among clinical studies. We reviewed our experience regarding the management and prognosis of these patients. METHODS: The charts of 4668 patients who underwent lung cancer surgery from 1983 to 2006 were retrospectively reviewed. We analysed the epidemiology, treatment, pathology and prognostic characteristics of those with extrathoracic synchronous solitary metastasis amenable to lung cancer surgery on a curative intend. RESULTS: There were 94 patients (sex ratio M/F 3.2/1, mean age 56 years). Surgery included pneumonectomy (n = 27), lobectomy (n = 65) and exploratory thoracotomy (n = 2). Pathology revealed adenocarcinomas (n = 57), squamous cell carcinoma (n = 20), large cell carcinoma (n = 14) and other NSCLC histology (n = 3). Lymphatic extension was N0 (n = 46), N1 (n = 17) and N2 (n = 31). Metastasis involved the brain (n = 57), adrenal gland (n = 12), bone (n = 14), liver (n = 5) and skin (n = 6). Sixty-nine metastases were resected. Five-year survival rate was 16% (median 13 months). Induction therapy, adenocarcinoma, N0 staging and lobectomy were criteria of better prognosis, but metastasis resection was not. CONCLUSIONS: These results suggest that extrathoracic synchronous solitary metastasis of pN0 adenocarcinoma may achieve long-term survival in the case of lung resection with or without metastasis resection. This pattern may reflect a specific tumour biology whose solitary metastasis benefits both from surgical or non-surgical treatment.
