Objectives: In 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., Methods: From 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., Results: In 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., Conclusion: In 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., (Copyright © 2023 AEC. Published by Elsevier España, S.L.U. All rights reserved.)

Introduction: The number of lung metastases (M1) of colorectal carcinoma (CRC) in relation to the findings of computed tomography (CT) is the object of study., Methods: Prospective and multicenter study of the Spanish Group for Surgery of CRC lung metastases (GECMP-CCR). The role of CT in the detection of pulmonary M1 is evaluated in 522 patients who underwent a pulmonary metastasectomy for CRC. We define M1/CT as the ratio between metastatic nodules and those found on preoperative CT. Disease-specific survival (DSS), disease-free survival (DFS), and surgical approach were analyzed using the Kaplan-Meier method., Results: 93 patients were performed by video-assisted surgery (VATS) and 429 by thoracotomy. In 90%, the M1/CT ratio was ≤1, with no differences between VATS and thoracotomy (94.1% vs 89.7%, p=0.874). In the remaining 10% there were more M1s than those predicted by CT (M1/CT>1), with no differences between approaches (8.6% vs 10%, p=0.874). 51 patients with M1/CT>1, showed a lower median DSS (35.4 months vs 55.8; p=0.002) and DFS (14.2 months vs 29.3; p=0.025) compared to 470 with M1/CT≤1. No differences were observed in DSS and DFS according to VATS or thoracotomy., Conclusions: Our study shows equivalent oncological results in the resection of M1 of CRC using VATS or thoracotomy approach. The group of patients with an M1/CT ratio >1 have a worse DSS and DFS, which may mean a more advanced disease than predicted preoperatively., (Copyright © 2022. Published by Elsevier España, S.L.U.)

Surgical removal of intrathoracic goiter can be performed by a cervical approach in the majority of patients. Review of literature shows that experienced surgeons need to perform an extracervical approach in 2-3% of cases. In spite of surgical management of substernal goiter is well defined, there is little available information about surgical approach of intrathoracic goiters extending beyond the aortic arch into the posterior mediastinum. We report two cases and propose combination of cervical incision and muscle-sparing lateral thoracotomy for posterior mediastinal goiter removal. In such cases, we do not favour sternotomy as posterior mediastinum is inaccessible due to the presence of heart and great vessels anterior to the thyroidal mass that would lead to perform a perilous blind dissection. Based in our experience, transcervical and thoracotomy approach is indicated for a complete and safe posterior mediastinal goiter removal., (Copyright © 2013 SEPAR. Published by Elsevier Espana.

Background: Surgical treatment of stage I non-small cell lung cancer (NSCLC) can be performed either by thoracotomy or by employing video-assisted thoracic surgery (VATS). The aim of this study was to compare long and short-term results of conventional surgery (CS) vs. VATS lobectomy in the treatment of stage I NSCLC., Materials and Methods: We performed a retrospective, analytical study of patients undergoing surgery for stage I NSCLC during the period January 1993 to December 2005. The variables analyzed were overall survival, recurrence, distant metastasis, morbidity, mortality and hospital stay. During this period, 256 anatomic lung resections were performed: 141 by CS and 115 by VATS., Results: There were statistically significant differences in: (i)mean hospital stay in patients with no complications (VATS group: 4.3 days vs. CS group: 8.7 days, P=.0001); (ii)mean hospital stay in patients with complications (VATS: 7.2 days vs. CS: 13.7 days, P=.0001), and (iii)morbidity (VATS: 15.6% vs. CS: 36.52%, P=.0001). No statistically significant differences were found in: (i)mortality (VATS: 2.17% vs. CS: 1.7%, P=.88); (ii)5-year overall survival (VATS: 68.1% vs. CS: 63.8%), and (iii) local recurrence and distant metastasis (P=.82)., Conclusions: VATS lobectomy is a safe and effective approach, with a shorter hospital stay and lower morbidity than CS; no statistically significant differences were observed in survival in patients undergoing surgery for stage I NSCLC., (Copyright © 2013 SEPAR.

Introduction: In recent years, there has been debate regarding the diagnostic accuracy of computed tomography (CT) in the identification of lung metastases and the need for lung palpation to determine the number of metastatic nodules. The aim of this study was to determine in which patients the CT scan was more effective in detecting all metastases., Methods: We studied all patients who underwent curative thoracotomy for pulmonary metastasis between 1998 and 2012. All cases were reviewed by two expert pulmonary radiologists before surgery. Statistical analyses were performed using Systat version 13., Results: The study included 183 patients (63.6% male) with a mean age of 61.7 years who underwent 217 interventions. The CT scan was correct in 185 cases (85.3%). Discrepancies observed: 26 patients (11.9%) with more metastases resected than observed and 6 cases (2.8%) with fewer metastases. In patients with one or two metastases of colorectal origin or a single metastasis of any other origin, the probability of finding extra nodules was 9.5%. In the remaining patients, the probability was 27.8%, with statistically significant differences (P=.001). The mean age of the patients in whom no unobserved nodules were detected was 62.9 years compared to 56.5 years on average in patients who were free from any metastases (P=.001)., Conclusions: Patients older than 60 years, with one or two metastases of colorectal origin or a single metastasis from any other origin were considered to be the group with low probability of having more metastases resected than observed., (Copyright © 2013 SEPAR.
