RESUMO

Background: The emergence of covid-19 has the potential to change the way in which the health care system can accommodate various patient populations and might affect patients with non-covid-19 problems. The Quebec Lung Cancer Network, which oversees thoracic oncology services in the province of Quebec under the direction of the Ministère de la Santé et des Services sociaux, convened to develop recommendations to deal with the potential disruption of services in thoracic oncology in the province of Quebec. The summary provided here has been adapted from the original document posted on the Programme québécois du cancer Web site at: https://www.msss.gouv.qc.ca/professionnels/documents/coronavirus-2019-ncov/PJ1_Recommandations_oncologie-thoracique-200415.pdf. Methods: Plans to optimize the health care system and potentially to prioritize services were discussed with respect to various levels of activity. For each level-of-activity scenario, suggestions were made for the services and treatments to prioritize and for those that might have to be postponed, as well as for potential alternatives to care. Results: The principal recommendation is that the cancer centre executive committee and the multidisciplinary tumour board always try to find a solution to maintain standard-of-care therapy for all patients with thoracic tumours, using novel approaches to treatment and the adoption of a network approach to care, as needed. Conclusions: The effect of the covid-19 pandemic on the health care system remains unpredictable and requires that cancer teams unite and offer the most efficient and innovative therapies to all patients under the various conditions that might be forced upon them.

RESUMO

RATIONALE: Although there have been several studies describing clinical and radiographic features about the novel coronavirus (COVID-19) infection, there is a lack of pathologic data conducted on biopsies or autopsies. PATIENT CONCERNS: A 56-year-old and a 70-year-old men with fever, cough, and respiratory fatigue were admitted to the intensive care unit and intubated for respiratory distress. DIAGNOSIS: The nasopharyngeal swab was positive for COVID-19 and the chest Computed Tomography (CT) scan showed the presence of peripheral and bilateral ground-glass opacities. INTERVENTIONS: Both patients developed pneumothoraces after intubation and was managed with chest tube. Due to persistent air leak, thoracoscopies with blebs resection and pleurectomies were performed on 23rd and 16th days from symptoms onset. OUTCOMES: The procedures were successful with no evidence of postoperative air-leak, with respiratory improvement. Pathological specimens were analyzed with evidence of diffuse alveolar septum disruption, interstitium thickness, and infiltration of inflammatory cells with diffuse endothelial dysfunction and hemorrhagic thrombosis. LESSONS: Despite well-known pulmonary damages induced by the COVID-19, the late-phase histological changes include diffused peripheral vessels endothelial hyperplasia, in toto muscular wall thickening, and intravascular hemorrhagic thrombosis.

RESUMO

Background: Lipomas are rarely seen tumors of adipose tissue that are benign in character. Although mostly located to the subcutaneous region, specifically in the upper back, neck, and shoulder, they may also occur in thoracic cavity. Aim: They aim of the study was to analyse clinical features and outcome of treatment of intrathoracic pleural lipomas. Materials and Method: We retrospectively evaluated the clinicopathological records of seven patients with intrathoracic lipomas who had undergone surgery between 2005 and 2017. We made analyses in terms of age, gender, admission complaints, lesion locations and dimensions, diagnostic techniques, operative procedures, histopathological features, and prognosis. Results: Four women and three men with a mean age 62.7 (range, 48-75 years) were included. They had chest pain (n = 2), effort dyspnea (n = 1) as the admission symptom, whereas four patients were asymptomatic, whose lesions were detected on chest radiography on an incidental basis. The radiological features of the tumors were well-demarcated, homogenous lesions with fat density. Tumors of all cases were excised, which were located on the right side in two patients and left in five. We used video-assisted thoracoscopy in two patients, single-port video-assisted thoracoscopy in three patients, thoracotomy in two patients. All lesions were of parietal pleural origin and were located intrathoracically. They had a range of size between 4 and 10 cm, with an average of 6.7 cm. All cases were operated with complete resection. At a mean follow-up duration of 4.7 years no recurrence was noted. Conclusion: Intrathoracic lipomas are rare, benignly behaving tumors. As it may prove difficult to differentiate them from malignant lesions and they may grow in an invasive growth pattern, surgery should be pursued in all patients for both diagnosis and treatment.

RESUMO

Since national health insurance began to cover robot-assisted thoracoscopic surgery (RATS) for malignant lung tumors, malignant mediastinal tumors, and benign mediastinal tumors in Japan starting in 2018, the number of RATS performed domestically has increased rapidly. In the case of undiagnosed lung tumor, it is necessary to perform a thoracoscopic lung biopsy in the port arrangement for RATS lung resection in the case of undiagnosed lung tumor. The 2 ports are placed in the same 8th intercostal space and a 3 cm utility thoracotomy is added to the 4th or 5th intercostal space for the thoracoscopic lung biopsy. Because the assistant uses the stapler from the port, the distance to the target area increases. When it is converted to RATS for malignant lung diseases, the utility thoracotomy is often hidden by the robot arm and all ports placed in the 8th intercostal space are far from the target area. Furthermore, the assistant working space outside the patient's body is limited by the robot arms. The Signia stapling system has an adapter to extend the shaft. By attaching the adapter, the shaft can be extended by 10 cm. This permits easy handling of the stapler during both thoracoscopic biopsy and RATS lung resection.

RESUMO

Pleural effusion adenosine deaminase (ADA) levels are elevated in various diseases. We investigated whether pleural effusion ADA levels differ among patients with malignant pleural mesothelioma (MPM), lung cancer (LC), and benign diseases, including tuberculous pleurisy. We examined 329 patients from February 2002 to July 2013. There were 131 MPM cases with ADA levels of 32.29 IU/L; 117 LC cases with ADA levels of 21.12 IU/L; 54 benign disease cases with ADA levels of 20.98 IU/L. A significant difference existed in pleural effusion ADA levels between MPM and benign disease patients. Pleural effusion ADA levels were significantly higher in MPM patients.

RESUMO

A man in his early 70s visited a previous hospital because of pancytopenia and was diagnosed with acute myeloid leukemia based on a bone marrowexamination. The karyotype was 46,XY, t(9;22)(q34;q11.2)[2/20], and real-time polymerase chain reaction(PCR)revealed minor bcr-abl chimeric mRNA. Finally, the patient was judged as having Philadelphia chromosome- positive acute myeloid leukemia, and remission induction chemotherapy with the JALSG AML 201 protocol was initiated in combination with dasatinib to achieve complete remission. After 3 courses of consolidation chemotherapy, the anticancer drugs were discontinued because of deterioration of his general condition and renal insufficiency. Six months after the initial treatment, he was referred to our department, and no evidence of recurrence was confirmed on bone marrow examination. However, 2 months later, right massive pleural effusion was detected, and he was admitted to the department of pneumology at our hospital. Thoracoscopic pleural biopsy was performed at the time of chest tube insertion, and he was diagnosed with acute myeloid leukemia extramedullary recurrence. Peripheral myeloblasts appeared and increased rapidly, accompanied by further exacerbation of renal function; thus, he received palliative care at the department of hematology and oncology.

RESUMO

A 50's-year-old woman was pointed out an abnormal shadow in the right lung field on chest X-ray. Chest computed tomography revealed a nodule in the upper lobe of the right lung. No specific finding was shown by bronchoscopy. A thoracoscopic operation was performed. Wedge resection was performed using automatic suturing devices. Intraoperative pathology revealed the lesion to be necrotizing granuloma, and the operation was finished without resection of the residual upper lobe. After surgery, the upper right lung field shadow and intrathoracic hematoma were observed, and reoperation was performed. The residual upper lobe was highly congested with bleeding from the stump, requiring lobectomy. It was possibly caused by a deep cut of the lung parenchyma with automatic suturing devices at lung wedge resection, resulting in obstruction of the drainage vein.

RESUMO

Minimally invasive oesophagectomy has become popular, but studies showed a higher rate of postoperative hiatus hernia compared with open oesophagectomy. Our video presents the laparoscopic biosynthetic mesh repair of a symptomatic giant hiatus hernia in a 71-year-old man who had undergone minimally invasive oesophagectomy one year earlier for distal adenocarcinoma of the oesophagus. The operative time was 120 minutes. The patient started oral intake on postoperative day one and was discharged on postoperative day three. Postoperative computed tomography at six months showed no signs of recurrence. In the setting of a symptomatic hiatus hernia post-minimally invasive oesophagectomy, we suggest an initial laparoscopic approach, because of its countless advantages.

RESUMO

CPAP is the most common treatment for obstructive sleep apnea.Serious complications from this treatment are very rare. Pneumothorax following lung barotrauma under CPAP therapy has been described in case reports only in patients with pre-existing lung and thoracic diseases.A 68-year-old sleep apnea patient without pre-existing lung or thoracic diseases and with established CPAP therapy since many years was admitted to the hospital after a severe thoracic pain event with persistent shortness of breath. Chest radiograph and computed tomography showed an extensive right-sided pneumothorax with basal bullous emphysema. After surgical treatment of the secondary spontaneous pneumothorax, on the third postoperative day CPAP with reduced pressure was re-introduced with satisfactory sleep apnea findings and without pneumothorax recurrence.As possible cause of pneumothorax in the patient, alveolar inflammatory changes due to over-distention and increased pressure in the alveoli was assumed, which can occur after years of CPAP treatment with gradual pressure increase.In summary, in sleep apnea patients treated with CPAP for years, after sudden onset of thoracic pain and shortness of breath possible spontaneous pneumothorax should be considered.

RESUMO

General anesthesia with double-lumen endobronchial intubation is considered mandatory for thoracoscopic bullectomy. We assessed the safety and feasibility of thoracoscopic bullectomy for treatment of primary spontaneous pneumothorax (PSP) under intubating laryngeal mask airway (ILMA) with spontaneous breathing sevoflurane anesthesia combined with thoracic paravertebral block (TPB).From January 2018 to December 2018, some 34 consecutive patients with PSP were treated by thoracoscopic bullectomy under ILMA with spontaneous breathing sevoflurane anesthesia combined with TPB (study group). To evaluate the safety and feasibility of this new technique, these patients were compared with the control group consisting of 34 consecutive patients with PSP who underwent thoracoscopic bullectomy using tracheal intubation with controlled ventilation from January 2017 to December 2017. The demographic characteristics, intraoperative surgical and anesthetic results, and postoperative results were assessed.The 2 groups had comparable anesthetic time, operation time, chest drainage time, postoperative hospital stays, and hospitalization cost. Visual analogue score (VAS) scores at 3 hours at rest and at coughing were significantly lower in the study group than in the control group (mean, 0.9 vs 2.0 and 1.8 vs 4.0, P = .024 and P = .006, respectively). No differences were seen in PaO2 values between the 2 groups in the intraoperative stage and postoperative stage (P > .05, respectively). The pH value was significantly lower in the intraoperative stage (mean, 7.28 vs 7.40, P = .01) and higher in the postoperative stage (mean, 7.35 vs 7.33, P = .014) in the study group than in the control group. The PaCO2 value was significantly higher in the intraoperative stage in the study group than in the control group (mean, 57.0 mm Hg vs 42.0 mm Hg, P = .015). In the study group, no cough reflex was found, and the level of collapse of the operative lung was excellent in 31 cases and good in 3 cases.Our study demonstrated that thoracoscopic bullectomy for treatment of PSP can be safely and feasibly performed in highly selected patients under ILMA with spontaneous breathing sevoflurane anesthesia combined with TPB.

RESUMO

Objective: To explore the safety and short-term and long-term efficacy of robot-assisted radical esophageal cancer surgery. Methods: A prospective randomized controlled trial was conducted. Patients who were preoperatively diagnosed as stage 0-IIIB esophageal squamous cell carcinoma and suitable for minimally invasive surgery in our hospital from January 1, 2014 to June 30, 2018 were prospectively enrolled. Those of age ≥75 years having received preoperative neoadjuvant therapy, contradicted to anesthesia or operation due to severe complications, with history of thoracotomy or laparotomy, with concurrent malignant tumors, without complete informations or refusing to participate in this study were excluded. Participants were randomly divided into the thoracoscopy-laparoscopy group and the robot group using a random number table in ratio of 1:1. Preoperative clinicopathological data, surgical data and postoperative outcomes were recorded. The patients were followed up mainly by telephone. Follow-up endpoint was recurrence of esophageal cancer and death. Kaplan-Meier method was used to estimate survival rate. The survival difference between the two groups was analyzed using the log-rank test. Results: According to above criteria, a total of 192 esophageal cancer patients were enrolled finally, including 144 males and 48 females with mean age of (61.9±8.6) years. The robot group had 94 cases, including 72 males and 22 females with mean age of (61.3±8.2) years, and the thoracoscopy-laparoscopy group had 98 cases, including 72 males and 26 females with mean age of (62.4±9.1) years. There were no significant differences in baseline data between the two groups (all P>0.05). Operation was abandoned in one case in each group due to extensive pleural cavity metastasis and one case in each group was converted to thoracotomy. The success rate of operation was 97.9% (92/94) in the robot group and 98.0% (96/98) in the thoracoscopy-laparoscopy group (χ(2)=0.002, P=0.996). The number of lymph nodes dissected in the robot group was significantly higher than that in the thoracoscopy-laparoscopy group (29.2±12.5 vs. 22.8±13.3, t=3.433, P=0.001), while there were no significant differences in operative time, intraoperative blood loss, R0 resection rate, postoperative 30-day mortality, postoperative hospital stay, ICU stay, time to withdrawal of chest drainage tube, ICU readmission, and postoperative morbidity of complications between the two groups (all P>0.05). The median follow-up time was 21 (3 to 57) months. During the follow-up, 3 cases and 4 cases were lost, and 2 cases and 3 cases died of other diseases in the robot group and in the thoracoscopy-laparoscopy group respectively. Recurrence occurred in 39 cases during follow-up, including 14 recurrences in the robotic group with 1- and 3-year recurrence-free survival rates of 92.4% and 87.6% respectively and the median recurrence time of 15 (9 to 42) months. There were 25 recurrences in the thoracoscopy-laparoscopy group with 1- and 3-year recurrence-free survival rates of 81.7% and 67.9% respectively and the median recurrence time of 9 (3 to 42) months. There was significant difference in recurrence-free survival between the two groups (χ(2)=4.193, P=0.041). Conclusions: The robotic surgical system has good oncology effect and surgical safety in the radical operation of esophageal cancer, which deserves further research and promotion.

RESUMO

BACKGROUND: Robot-assisted thoracoscopic surgery (RATS) is useful for surgery in the apical region of the chest cavity, as it narrows towards the head. Here, we describe a nonfunctional, rib-invasive paraganglioma arising in the posterior mediastinum that was successfully removed using RATS combined with chest wall resection. CASE PRESENTATION: A 31-year-old woman presented with a posterior mediastinal mass on chest computed tomography (CT) scan during a medical check-up 2 years prior. Positron emission tomography/computed tomography scan with F-18 fluorodeoxyglucose revealed a mass associated with standardized uptake maximum value of 2.69. With a preoperative diagnosis of neurogenic tumor by CT-guided percutaneous fine-needle aspiration biopsy, we performed robot-assisted tumor resection combined with chest wall resection. The wristed instruments of the robotic surgical system have increased range of motion and enabled the tumor resection without organ injury in the thoracic cavity. Histopathology examination revealed a non-functional paraganglioma with rib invasion. CONCLUSIONS: RATS is a useful technique, enabling safer and easier resection of a mediastinal tumor adjacent to surrounding organs.

RESUMO

The outcomes of minimally invasive thoracoscopic pulmonary segmentectomy for non-small cell lung cancer (NSCLC) still need to be defined. This study aimed to investigate the feasibility and effectiveness of thoracoscopic pulmonary segmentectomy in patients with early peripheral NSCLC.This was a retrospective study of patients with early peripheral NSCLC admitted between January 2013 and January 2017. Patients were divided into the segmentectomy and lobectomy groups (40/group), according to the surgery they underwent. Blood loss, operation time, removal of drainage tube time, inflammatory response after operation, postoperative complications, postoperative lung function, local recurrence, and survival were compared.Blood loss and removal of drainage tube time were not significantly different between the 2 groups (all P > .05). Operation time in the segmentectomy group was longer than in the lobectomy group (P < .001). The postoperative interleukin-6, procalcitonin, and C-reactive protein changes in the segmentectomy group were significantly lower than in the lobectomy group (all P < .001). The pulmonary function at 2 weeks was significantly reduced in the 2 groups (all P < .001), but it was better in the segmentectomy group than in the lobectomy group (all P < .05). The 1- and 3-year local recurrence disease-free, and overall survival rates were not significantly different between the 2 groups (P > .05). The multivariable analysis could not identify any factor associated with local recurrence or survival (all P > .05).Thoracoscopic pulmonary segmentectomy and lobectomy are both acceptable for the treatment of early peripheral NSCLC, but segmentectomy was associated with lower postoperative inflammation and better postoperative pulmonary function than lobectomy.

RESUMO

BACKGROUND: Mediastinal teratoma is a rare disease, many cases were reported before, but few articles focus on large case analyses. The objective of this article is to summarize the clinical characteristics of benign mediastinal teratoma and the experience of surgical treatment, especially thoracoscopic surgery for benign mediastinal teratoma. METHODS: The clinical data of 108 patients with benign mediastinal teratoma confirmed by operation and pathology from January 1992 to January 2018 were analyzed retrospectively. The clinical symptoms, imaging examination, surgical methods and prognosis of all patients were analyzed. We compared the difference of thoracoscopic surgery and thoracotomy surgery using 102 patients underwent only chest surgery. Normally distributed continuous variables were compared by independent sample t test. Categorical variables were analyzed by chi-square test. RESULTS: Imaging examination showed that all 108 cases of mediastinal teratoma were located in the anterior region of mediastinum. All cases underwent surgical resection, postoperative pathology confirmed that all cases were benign. 1 case was taken simple neck collar incision, 5 case was taken median thoracotomy combined with neck incision, other 102 cases were taken thoracoscopic surgery (22) or thoracotomy surgery (80). 4 cases were treated with partial pericardial resection due to adhesions, 12 cases underwent partial pericardial resection, 5 cases underwent lobectomy, 9 cases underwent wedge resection of lobe, and 2 patients underwent anonymous vein angioplasty. 1 case underwent second operation because of postoperative bleeding, 1 case of chylothorax, 1 case of recurrent laryngeal nerve injury, 2 cases of wound infection, 1 case of secondary pulmonary infection. 106 cases were followed up, period from 12 months to 10 years, no recurrence of tumor was found. Comparing to take thoracotomy surgery, patients underwent thoracoscopic surgery has strong advantage on intraoperative blood loss and hospital stay days after surgery (P < 0.05). tumor maximum diameter is larger for thoracotomy surgery group, as well as more patients suffer estimated adhesions from preoperative imaging. so we compared above parameters in patients with tumor diameter less than 10 cm with or without estimated adhesions from preoperative imaging, a strong advantage still can be found in thoracoscopic surgery group, inpatients with estimated adhesions from preoperative imaging, intraoperative blood loss (38.75 ± 15.53 vs 169.17 ± 208.82., P = 0.04) and hospital stay days after surgery (5.50 ± 0.93 vs 9.43 ± 6.54., P = 0.04) were better. In patients without estimated adhesions from preoperative imaging, intraoperative blood loss (46.67 ± 10.00 vs 110.53 ± 123.13., P = 0.06) and hospital stay days after surgery (4.70 ± 1.16 vs 7.53 ± 2.32., P = 0.01) were better. Especially, in thoracoscopic surgery group, hospital stay days after surgery was significantly shorter. CONCLUSION: The clinical manifestations and imaging performance of benign mediastinal teratoma were complicated, and the surgical treatment was effective. Compared with traditional thoracotomy surgery, thoracoscopic surgery can improve patients' quality of life, less intraoperative blood loss, and less hospital stay days after surgery, so if condition is permitted, thoracoscopic surgery should be a better choice.

RESUMO

Introduction: Brugada syndrome (BrS) is an inherited disease characterized by an increased risk of sudden cardiac death (SCD). Therapeutic options in symptomatic patients are limited to implantable cardioverter defibrillator (ICD) and quinidine, but catheter ablation of the right ventricular outflow tract (RVOT) offers a potential cure. Different ablation strategies have been used to treat patients with symptomatic Brugada syndrome. Epicardial radiofrequency substrate ablation of the RVOT/right ventricle (RV) has emerged as a promising tool for the management of the disease.Areas covered: The historical management of BrS, endocardial and epicardial ablation techniques, the use of sodium channel blockers (SCB) and complications are summarized here.Expert opinion: Ventricular fibrillation (VF)-triggering premature ventricular contractions (PVCs) in patients with BrS are unpredictable, spontaneous ones are rarely present to be mapped, making this approach impractical. Furthermore, endocardial mapping for BrS substrates does not seem effective due to the epicardial pathological substrate localization. The size variation of the BrS substrate areas during SCB infusion suggests a dynamic process as arrhythmogenic basis and SCB infusion should guide BrS epicardial ablation of all abnormal potentials areas. If BrS epicardial ablation can truly provide long-term prevention of ventricular arrhythmias it may potentially become an alternative to ICD therapy.

RESUMO

Little information is available concerning the usefulness of electrophysiological confirmation followed by totally thoracoscopic ablation. This study aimed to examine whether postprocedural electrophysiological confirmation is always necessary after totally thoracoscopic ablation (TTA) in patients with isolated persistent atrial fibrillation. Forty-five patients with isolated persistent atrial fibrillation were randomized into 2 groups those who received routine electrophysiological confirmation and additional catheter ablation after totally thoracoscopic ablation (the hybrid group [n = 22]) and those who did not (the TTA group [n = 23]). Electrophysiological study was performed 4 or 5 days after surgery. No early or late mortality occurred. In the hybrid group, 5 patients (23%, 5/22) required additional ablation due to residual potential in the left atrium. At a year postoperatively, normal sinus rhythm was observed in 89% of patients (40/45) and similar in both groups (Odds ratio 0.80, 95% confidence interval 0.32 to 1.99). During follow-up, sinus rhythm was maintained in 16 patients (70%) in the TTA group without additional catheter ablation, which was similar (p = 0.920) to the results in the hybrid group (n = 15, 68.2%). Event-free survival rate at 12 months did not differ between groups (TTA group vs hybrid group, 78% vs 77%; p = 0.633). In simple Cox regression analysis, preoperative left atrium volume index was associated with atrial arrhythmia (p = 0.030, hazards ratio 1.087, 95% confidence interval 1.01-1.18). In conclusion, thoracoscopic ablation provided good 1-year durability in patients with isolated persistent AF irrespective of postprocedural electrophysiological confirmation. Seventy-percent of the TTA group did not need additional catheter ablation.

RESUMO

Hepatopulmonary hydatidosis in young children is a rare and atypical presentation of Echinococcus granulosus infection. We report the first case of cystic echinococcosis caused by a microvariant of E. granulosus sensu stricto. Chemotherapy and systemic corticoids were administered before curative surgery was performed. Recurrence was not observed for more than 24 months of follow-up.

RESUMO

BACKGROUND: Patients undergoing thoracic lung wedge resection could benefit from tubeless strategies. However, postoperative pneumothorax is a primary limiting factor for such strategies. Accordingly, we evaluated the safety and efficacy of the prophylactic use of an air-extraction catheter as an improved drainage strategy and compared the findings with those for chest tube drainage in patients undergoing thoracic wedge resection. METHODS: Patients undergoing thoracic wedge resection between August 2017 and October 2018 were enrolled in this single-center, randomized, open-label, noninferiority trial. Patients who received an improved drainage strategy involving the use of a prophylactic air-extraction catheter were randomized to the intervention group, whereas those who underwent routine chest tube drainage were assigned to the control group. Analysis was based on the per-protocol population. The primary outcome was the incidence of pneumothorax on postoperative day 1. Secondary outcomes included patient recovery and related complications, including pleural effusion, lung infection, numeric rating scale score for pain, postoperative chest tube or catheter removal, postoperative hospitalization, and chest tube reinsertion. RESULTS: A total of 96 patients were randomized. Baseline demographic and clinical characteristics were similar between groups. The incidence of pneumothorax in the intervention and control groups was 10.0% and 9.1%, respectively (noninferiority, P = 1.00). In addition, there were no significant between-group differences in secondary outcomes. A significantly lower pain score was observed in the intervention group (P = .001). CONCLUSIONS: The improved drainage strategy is not inferior to standard chest tube drainage after thoracic wedge resection and should be popularized.
