ABSTRACT

BACKGROUND AND OBJECTIVE: This study aims to quantify bedside pleural procedures performed at a quaternary teaching hospital describing technical and epidemiological aspects. MATERIALS AND METHODS: The authors retrospectively reviewed consecutive patients who underwent invasive thoracic bedside procedures between March 2022 and February 2023. RESULTS: 463 chest tube insertions and 200 thoracenteses were performed during the study period. Most procedures were conducted by 1st-year Thoracic Surgery residents, with Ultrasound Guidance (USG). There was a notable preference for small-bore pigtail catheters, with a low rate of immediate complications. CONCLUSION: Bedside thoracic procedures are commonly performed in current medical practice and are significant in surgical resident training. The utilization of pigtail catheters and point-of-care ultrasonography by surgical residents in pleural procedures is increasingly prevalent and demonstrates high safety.

ABSTRACT

OBJECTIVE: To compare 90-day morbidity in patients undergoing lung lobectomy performed by either robotic-assisted thoracic surgery (RATS) or video-assisted thoracic surgery (VATS). Intraoperative complications, drainage time, length of hospital stay, postoperative pain, postoperative quality of life, and readmissions within 90 days were also compared. METHODS: This was a two-arm randomized clinical trial including patients with lung lesions (primary lung cancer or lung metastasis) who were candidates for lung lobectomy. Patients with comorbidities that precluded surgical treatment were excluded. All patients followed the same postoperative protocol. RESULTS: The overall sample comprised 76 patients (39 in the VATS group and 37 in the RATS group). The two groups were similar regarding gender, age, BMI, FEV1 in % of predicted, and comorbidities. Postoperative complications within 90 days tended to be more common in the VATS group than in the RATS group, but the difference was not significant (p = 0.12). However, when only major complications were analyzed, this tendency disappeared (p = 0.58). Regarding postoperative outcomes, the VATS group had a significantly higher number of readmissions within 90 days than did the RATS group (p = 0.029). No significant differences were found regarding intraoperative complications, drainage time, length of hospital stay, postoperative pain, and postoperative quality of life. CONCLUSIONS: RATS and VATS lobectomy had similar 90-day outcomes. However, RATS lobectomy was associated with a significant reduction in the 90-day hospital readmission rate. Larger studies are necessary to confirm such a finding.(ClinicalTrials.gov identifier: NCT02292914 [http://www.clinicaltrials.gov/]).

ABSTRACT

BACKGROUND: The use of Indwelling Pleural Catheter (IPC) in the care of patients with Malignant Pleural Effusion (MPE) is well established, however studies involving public health systems of low and middle-income countries are still lacking. This study aimed to determine the effect of IPC on the respiratory symptoms and Quality of Life (QoL) of patients with MPE in the setting of a Brazilian public health system. METHODS: From August 2015 to November 2019, patients with MPE underwent IPC placement and were prospectively followed. QoL and respiratory symptoms were assessed by the EORTC questionnaires (QLQ-30; LC13) and Visual Analogue Scale (VAS), respectively, at pre-treatment, 30 , and 60 days after IPC placement. RESULTS: 56 patients were enrolled with 57 catheters inserted. The mean age was 63 (23‒88) years, of which 17 (30%) were men and 39 (70%) were women. Breast 24 (42%) and lung 21 (37%) were the main primary neoplasms. Cellulitis was the most common complication and all patients recovered with appropriate antimicrobial therapy. QoL did not change significantly over time, however, the VAS showed a significant improvement in dyspnea (+1.2: -0.5; p = 0.001). CONCLUSION: IPC relieves respiratory symptoms without compromising the QoL, with a low complication rate. It represents a suitable option for patients with MPE and short LE in an emerging country.

RESUMO Objetivo: Comparar a morbidade em 90 dias de pacientes submetidos à lobectomia pulmonar por robotic-assisted thoracic surgery (RATS, cirurgia torácica robótica) ou por video-assisted thoracic surgery (VATS, cirurgia torácica videoassistida). Complicações intraoperatórias, tempo de drenagem, tempo de internação hospitalar, dor pós-operatória, qualidade de vida pós-operatória e reinternações em 90 dias também foram comparados. Métodos: Ensaio clínico randomizado, com dois braços, incluindo pacientes com lesões pulmonares (câncer de pulmão primário ou metástase pulmonar) candidatos à lobectomia pulmonar. Foram excluídos pacientes com comorbidades que impossibilitassem o tratamento cirúrgico. Todos os pacientes seguiram o mesmo protocolo pós-operatório. Resultados: A amostra total foi composta por 76 pacientes (39 no grupo VATS e 37 no grupo RATS). Os dois grupos foram semelhantes quanto a sexo, idade, IMC, VEF1 em % do previsto e comorbidades. Complicações pós-operatórias em 90 dias tenderam a ser mais frequentes no grupo VATS do que no grupo RATS, mas a diferença não foi significativa (p = 0,12). No entanto, quando analisadas apenas as complicações maiores, essa tendência desapareceu (p = 0,58). Quanto aos desfechos pós-operatórios, o grupo VATS apresentou um número significativamente maior de reinternações em 90 dias do que o grupo RATS (p = 0,029). Não foram encontradas diferenças significativas quanto a complicações intraoperatórias, tempo de drenagem, tempo de internação hospitalar, dor pós-operatória e qualidade de vida pós-operatória. Conclusões: A lobectomia por RATS e a lobectomia por VATS apresentaram desfechos em 90 dias semelhantes. No entanto, a lobectomia por RATS foi associada a uma redução significativa na taxa de reinternação hospitalar em 90 dias. Estudos maiores são necessários para confirmar esse achado.

QoL and respiratory symptoms were assessed by the EORTC questionnaires (QLQ-30; LC13) and Visual Analogue Scale (VAS), respectively, at pre-treatment, 30 , and 60 days after IPC placement. Results: 56 patients were enrolled with 57 catheters inserted. The mean age was 63 (23‒88) years, of which 17 (30%) were men and 39 (70%) were women. Breast 24 (42%) and lung 21 (37%) were the main primary neoplasms. Cellulitis was the most common complication and all patients recovered with appropriate antimicrobial therapy. QoL did not change significantly over time, however, the VAS showed a significant improvement in dyspnea (+1.2: -0.5; p = 0.001). Conclusion: IPC relieves respiratory symptoms without compromising the QoL, with a low complication rate. It represents a suitable option for patients with MPE and short LE in an emerging country. HIGHLIGHTS Indwelling pleural catheter represents a suitable option for patients with malignant pleural effusion and short life expectancy. It relieves respiratory symptoms without compromising the quality of life, and the complication rate is low, even in an emerging country, with a low socioeconomic and under-educated patient population. The rate of spontaneous pleurodesis was 45%. The analysis of the visual analog scale showed significant control of dyspnea (p = 0.001), but pain and quality of life did not change significantly.

ABSTRACT

OBJECTIVE: Adjuvant chemotherapy (AC) improves survival of patients with resected non-small cell lung cancer (NSCLC). However, the cisplatin-vinorelbine regimen has been associated with a significant risk of clinically relevant toxicity. We sought to evaluate the effectiveness, safety, and feasibility of AC for NSCLC patients in a real-world setting. METHODS: This was a single-center, retrospective cohort study of patients with stage I-III NSCLC undergoing surgery with curative intent between 2009 and 2018. AC was administered at the discretion of physicians. The patients were divided into two groups: AC group and no AC (control) group. Study outcomes included overall survival (OS) and recurrence-free survival (RFS), as well as the safety profile and feasibility of the cisplatin-vinorelbine regimen in a real-world setting. RESULTS: The study involved 231 patients, 80 of whom received AC. Of those, 55 patients received the cisplatin-vinorelbine regimen. Survival analyses stratified by tumor stage showed that patients with stage II NSCLC in the AC group had better RFS (p = 0.036) and OS (p = 0.017) than did those in the no AC group. Among patients with stage III NSCLC in the AC group, RFS was better (p < 0.001) and there was a trend toward improved OS (p = 0.060) in comparison with controls. Of those who received the cisplatin-vinorelbine regimen, 29% had grade 3-4 febrile neutropenia, and 9% died of toxicity. CONCLUSIONS: These results support the benefit of AC for NSCLC patients in a real-world setting. However, because the cisplatin-vinorelbine regimen was associated with alarming rates of toxicity, more effective and less toxic alternatives should be investigated.

RESUMO Objetivo: A quimioterapia adjuvante melhora a sobrevida de pacientes com câncer pulmonar de células não pequenas (CPCNP) ressecado. No entanto, o esquema cisplatina-vinorelbina está relacionado com risco significativo de toxicidade clinicamente relevante. Nosso objetivo foi avaliar a eficácia, segurança e viabilidade da quimioterapia adjuvante para pacientes com CPCNP em um cenário de mundo real. Métodos: Estudo retrospectivo de coorte realizado em um único centro com pacientes com CPCNP em estágio I-III submetidos a cirurgia com intuito curativo entre 2009 e 2018. A quimioterapia adjuvante foi administrada a critério dos médicos. Os pacientes foram divididos em dois grupos: quimioterapia adjuvante e sem quimioterapia adjuvante (grupo controle). Os desfechos estudados foram sobrevida global (SG) e sobrevida livre de recidiva (SLR), bem como o perfil de segurança e viabilidade do esquema cisplatina-vinorelbina em um cenário de mundo real. Resultados: O estudo envolveu 231 pacientes, 80 dos quais receberam quimioterapia adjuvante. Destes, 55 receberam o esquema cisplatina-vinorelbina. As análises de sobrevida estratificadas pelo estágio do tumor mostraram que os pacientes com CPCNP em estágio II que receberam quimioterapia adjuvante apresentaram melhor SLR (p = 0,036) e SG (p = 0,017) do que os do grupo controle. Entre os pacientes com CPCNP em estágio III que receberam quimioterapia adjuvante, a SLR foi melhor (p < 0,001) e houve uma tendência a melhor SG do que no grupo controle (p = 0,060). Dos que receberam o esquema cisplatina-vinorelbina, 29% apresentaram neutropenia febril de grau 3-4, e 9% morreram em virtude de toxicidade. Conclusões: Os resultados confirmam o efeito benéfico da quimioterapia adjuvante em pacientes com CPCNP em um contexto real. No entanto, o esquema cisplatina-vinorelbina relacionou-se com taxas alarmantes de toxicidade e alternativas mais eficazes e menos tóxicas devem ser investigadas.

ABSTRACT

OBJECTIVE: To evaluate the evolution of clinical and epidemiological data, as well as data related to diagnosis, staging, treatment, and survival, among patients undergoing curative surgery for lung cancer at a tertiary referral center in the city of São Paulo, Brazil. METHODS: This was a retrospective study of cases in the International Association for the Study of Lung Cancer database. We selected only cases of patients undergoing curative surgery between January of 2011 and April of 2018. We determined overall and disease-free survival at 36 months and compared the data between two periods (2011-2014 and 2015-2018). RESULTS: Comparing the two periods (N = 437 cases), we observed trends toward increases in the number of female patients, as well as in the proportions of former smokers (44.09% vs. 53.59%), of patients diagnosed with adenocarcinoma (52.21% vs. 59.72%), and of patients diagnosed at an earlier pathological stage, together with a decrease in 30-day mortality (4.05% vs. 2.39%). There were significant increases in the proportions of cases diagnosed at an earlier clinical stage (p = 0.002) or incidentally (p = 0.003). Although lobectomy was the main surgical technique employed, there was a proportional increase in segmentectomies (2.67% vs. 7.11%; p = 0.026). Overall and disease-free survival rates were 79.4% (95% CI: 74.0-83.9%) and 75.1% (95% CI: 69.1-80.1%), respectively. The difference in overall survival between the periods lost statistical significance when adjusted for pathological stage, the only factor that affected survival (log-rank: p = 0.038 to p = 0.079). CONCLUSIONS: The clinical and epidemiological evolution presented in this study corroborates global trends. The decrease in 30-day mortality was probably due to better patient selection and improved surgical techniques.

ABSTRACT

OBJECTIVE: To evaluate the results of resection of tumors of the thymus by robotic thoracic surgery, analyzing the extent of resection, postoperative complications, time of surgery, and length of stay. METHODS: Retrospective study from a database involving patients diagnosed with a tumor of the thymus and undergoing robotic thoracic surgery at one of seven hospitals in Brazil between October of 2015 and June of 2018. RESULTS: During the study period, there were 18 cases of resection of tumors of the thymus: thymoma, in 12; carcinoma, in 2; and carcinoid tumor, in 1; high-grade sarcoma, in 1; teratoma, in 1; and thymolipoma, in 1. The mean lesion size was 60.1 ± 32.0 mm. Tumors of the thymus were resected with tumor-free margins in 17 cases. The median (interquartile range) for pleural drain time and hospital stay, in days, was 1 (1-3) and 2 (2-4), respectively. There was no need for surgical conversion, and there were no major complications. CONCLUSIONS: Robotic thoracic surgery for resection of tumors of the thymus has been shown to be feasible and safe, with a low risk of complications and with postoperative outcomes comparable to those of other techniques.

ABSTRACT

OBJECTIVE: To describe the morbidity, mortality, and rate of complete resection associated with robotic surgery for the treatment of non-small cell lung cancer in Brazil, as well as to report the rates of overall survival and disease-free survival in patients so treated. METHODS: This was a retrospective study of patients diagnosed with non-small cell lung carcinoma and undergoing resection by robotic surgery at one of six hospitals in Brazil between February of 2015 and July of 2018. Data were collected retrospectively from the electronic medical records. RESULTS: A total of 154 patients were included. The mean age was 65 ± 9.5 years (range, 30-85 years). The main histological diagnosis was adenocarcinoma, which was identified in 128 patients (81.5%), followed by epidermoid carcinoma, identified in 14 (9.0%). Lobectomy was performed in 133 patients (86.3%), and segmentectomy was performed in 21 (13.7%). The mean operative time was 209 ± 80 min. Postoperative complications occurred in 32 patients (20.4%). The main complication was air leak, which occurred in 15 patients (9.5%). The median (interquartile range) values for hospital stay and drainage time were 4 days (3-6 days) and 2 days (2-4 days), respectively. There was one death in the immediate postoperative period (30-day mortality rate, 0.5%). The mean follow-up period was 326 ± 274 days (range, 3-1,110 days). Complete resection was achieved in 97.4% of the cases. Overall mortality was 1.5% (3 deaths), and overall survival was 97.5%. CONCLUSIONS: Robotic pulmonary resection proved to be a safe treatment for lung cancer. Longer follow-up periods are required in order to assess long-term survival.

ABSTRACT

OBJECTIVE: to report our initial experience with pulmonary robotic segmentectomy, describing the surgical technique, the preferred positioning of portals, initial results and outcomes. METHODS: we collected data, from a prospective robotic surgery database, on patients undergoing robotic segmentectomy between January 2017 and December 2018. All patients had lung cancer, primary or secondary, or benign diseases, and were operated on with the Da Vinci system, by the three portals technique plus one utilitarian incision of 3cm. We dissected the hilar structures individually and performed the ligatures of the arterial and venous branches, of the segmental bronchi, as well as a parenchymal transection, with endoscopic staplers. We carried out systematic dissection of mediastinal lymph nodes for non-small cell lung cancer (NSCLC) cases. RESULTS: forty-nine patients, of whom 33 were women, underwent robotic segmentectomy. The average age was of 68 years. Most patients had NSCLC (n=34), followed by metastatic disease (n=11) and benign disease (n=4). There was no conversion to laparoscopic or open surgery, or to lobectomy. The median total operative time was 160 minutes, and the median console time, 117 minutes. Postoperative complications occurred in nine patients (18.3%), of whom seven (14.2%) had prolonged hospitalization (>7 days) due to persistent air fistula (n=4; 8.1%) or abdominal complications (n=2.4%). CONCLUSION: robotic segmentectomy is a safe and viable procedure, offering a short period of hospitalization and low morbidity.


OBJETIVO: relatar nossa experiência inicial com a segmentectomia robótica, descrevendo a técnica operatória, a colocação preferencial dos portais, os resultados iniciais e desfechos. MÉTODOS: dados clínicos de pacientes submetidos à segmentectomia robótica, entre janeiro de 2017 e dezembro de 2018, foram obtidos de um banco de dados prospectivo de cirurgia robótica. Todos os pacientes tinham câncer de pulmão, primário ou secundário, ou doenças benignas, e foram operados usando o sistema Da Vinci com a técnica de três portais mais uma incisão utilitária de 3cm. As estruturas hilares foram dissecadas individualmente e as ligaduras dos ramos arteriais e venosos, dos brônquios segmentares, assim como, a transecção do parênquima, realizadas com grampeadores endoscópicos. Dissecção sistemática dos linfonodos mediastinais foi realizada para os casos de câncer de pulmão não de pequenas células (CPNPC). RESULTADOS: quarenta e nove pacientes, dos quais 33 mulheres, foram submetidos à segmentectomia robótica. A média de idade foi de 68 anos. A maioria dos pacientes tinha CPNPC (n=34), seguido de doença metastática (n=11) e doenças benignas (n=4). Não houve conversão para cirurgia aberta ou vídeo, ou conversão para lobectomia. A mediana do tempo operatório total foi de 160 minutos e do tempo de console foi de 117 minutos. Complicações pós-operatórias ocorreram em nove pacientes (18,3%), dos quais sete (14,2%) tiveram internação prolongada (>7 dias) devido à fístula aérea persistente (n=4; 8,1%) ou complicações abdominais (n=2; 4%). CONCLUSÃO: a segmentectomia robótica é um procedimento seguro e viável, oferecendo curto período de internação e baixa morbidade.

ABSTRACT

BACKGROUND: In the last decade, robotic video-assisted thoracic surgery (R-VATS) has grown significantly and consolidated as an alternative to video-assisted thoracic surgery. The objective of this study is to present the implementation as well as the experience with R-VATS accumulated by 2 Brazilian groups. We also compared the outcomes of procedures performed during the learning curve and after a more mature experience. METHODS: Retrospective cohort study included all R-VATS procedures performed since April 2015 until April 2018. We describe the process of implantation of robotic surgery, highlighting the peculiarities and difficulties found in a developing country. Moreover, we reported our descriptive results and compared the first 60 patients to the subsequent cases. RESULTS: Two hundred and five patients included 101 females/104 males. Mean age was 61.7 years. There were hundred and sixty-four pulmonary resections, 39 resections of mediastinal lesions, 1 diaphragmatic plication, and 1 resection of a hilar tumor. Median operative times were 205 min for lung resections and 129 min for mediastinal. There was no conversion to VATS or thoracotomy or major intraoperative complications. Median length of stay was 3 days for pulmonary resections and 1 day for mediastinal. Postoperative complications occurred in 35 cases (17.0%)-prolonged air leak was the most common (17 cases). One fatality occurred in an elderly patient with pneumonia and sepsis (0.4%). Comparison of the first 60 patients (learning curve) with subsequent 145 patients (consolidated experience) showed significant differences in surgical and ICU time, both favoring consolidated experience. CONCLUSIONS: Our results were comparable to the literature. Robotic thoracic surgery can be safely and successfully implemented in tertiary hospitals in emerging countries provided that all stakeholders are involved and compromised with the implementation process.

ABSTRACT

INTRODUCTION: Pericardial effusion (PE) is a complication of late-stage cancer and some patients never leave the hospital despite drainage. The main objective of this study was to identify predictors of hospital discharge in cancer patients with (PE) who underwent pericardial drainage. We also report the occurrence of paradoxical hemodynamic instability (PHI). METHODS AND MATERIALS: A retrospective study was carried out in a cancer center. Patients included had malignancy, PE, and underwent surgical drainage. An institutional database was reviewed for preoperative variables, analyzed for hospital discharge. RESULTS: One-hundred and thirteen patients were included, with a mean age of 54 years old (SD 14.3). Sixty-three patients were discharged from hospital (55.7%). Age (odds ratio [OR], 1.04; P = 0.004), higher ECOG status (OR, 0.63; P = 0.019), recent chemotherapy (OR, 3.40; P = 0.007), and renal failure (OR, 0.14; P = 0.002) were associated with hospital discharge. Median survival was 43 days (IQ 25%-75%; 15-162). Patients with pulmonary embolism or neutropenia were at greater risk of developing PHI (OR, 10.11; P = 0.009 and OR, 12.13; P = 0.015, respectively). CONCLUSION: Almost half of the patients never left the hospital. Patients with no chemotherapy within 45 days of procedure, patients with renal failure and higher ECOG status are at greater risk of not getting discharged. PHI remains a serious condition with high mortality.

ABSTRACT

RESUMO Objetivo: relatar nossa experiência inicial com a segmentectomia robótica, descrevendo a técnica operatória, a colocação preferencial dos portais, os resultados iniciais e desfechos. Métodos: dados clínicos de pacientes submetidos à segmentectomia robótica, entre janeiro de 2017 e dezembro de 2018, foram obtidos de um banco de dados prospectivo de cirurgia robótica. Todos os pacientes tinham câncer de pulmão, primário ou secundário, ou doenças benignas, e foram operados usando o sistema Da Vinci com a técnica de três portais mais uma incisão utilitária de 3cm. As estruturas hilares foram dissecadas individualmente e as ligaduras dos ramos arteriais e venosos, dos brônquios segmentares, assim como, a transecção do parênquima, realizadas com grampeadores endoscópicos. Dissecção sistemática dos linfonodos mediastinais foi realizada para os casos de câncer de pulmão não de pequenas células (CPNPC). Resultados: quarenta e nove pacientes, dos quais 33 mulheres, foram submetidos à segmentectomia robótica. A média de idade foi de 68 anos. A maioria dos pacientes tinha CPNPC (n=34), seguido de doença metastática (n=11) e doenças benignas (n=4). Não houve conversão para cirurgia aberta ou vídeo, ou conversão para lobectomia. A mediana do tempo operatório total foi de 160 minutos e do tempo de console foi de 117 minutos. Complicações pós-operatórias ocorreram em nove pacientes (18,3%), dos quais sete (14,2%) tiveram internação prolongada (>7 dias) devido à fístula aérea persistente (n=4; 8,1%) ou complicações abdominais (n=2; 4%). Conclusão: a segmentectomia robótica é um procedimento seguro e viável, oferecendo curto período de internação e baixa morbidade.


ABSTRACT Objective: to report our initial experience with pulmonary robotic segmentectomy, describing the surgical technique, the preferred positioning of portals, initial results and outcomes. Methods: we collected data, from a prospective robotic surgery database, on patients undergoing robotic segmentectomy between January 2017 and December 2018. All patients had lung cancer, primary or secondary, or benign diseases, and were operated on with the Da Vinci system, by the three portals technique plus one utilitarian incision of 3cm. We dissected the hilar structures individually and performed the ligatures of the arterial and venous branches, of the segmental bronchi, as well as a parenchymal transection, with endoscopic staplers. We carried out systematic dissection of mediastinal lymph nodes for non-small cell lung cancer (NSCLC) cases. Results: forty-nine patients, of whom 33 were women, underwent robotic segmentectomy. The average age was of 68 years. Most patients had NSCLC (n=34), followed by metastatic disease (n=11) and benign disease (n=4). There was no conversion to laparoscopic or open surgery, or to lobectomy. The median total operative time was 160 minutes, and the median console time, 117 minutes. Postoperative complications occurred in nine patients (18.3%), of whom seven (14.2%) had prolonged hospitalization (>7 days) due to persistent air fistula (n=4; 8.1%) or abdominal complications (n=2.4%). Conclusion: robotic segmentectomy is a safe and viable procedure, offering a short period of hospitalization and low morbidity.
