Early outcomes of robotic versus video-thoracoscopic anatomical segmentectomy: a propensity score-matched real-world study.

Objectives: Minimally invasive anatomic segmentectomy for the resection of pulmonary nodules has significantly increased in the last few years. Nevertheless, there is limited evidence on the safety and feasibility of robotic segmentectomy compared to video-assisted thoracic surgery. This study aimed to compare the real-world early outcomes of robotic and video-thoracoscopic surgery in anatomic segmentectomy.

The «Weekday Effect» Does Not Have an Impact on the Development of Complications or Mortality After Pulmonary Resection: Retrospective Cohort Study.

Objective: To determine whether elective anatomic pulmonary resection surgery carried out at the end of the week is associated with a higher mortality and postoperative morbidity than surgery performed at the beginning of the week.

Method: Historical cohort study. All patients undergoing anatomical pulmonary resection between January 2013 and November 2018 in our center were included.

SECT Clinical practice guideline on the management of patients with spontaneous pneumothorax.

This clinical practice guideline (CPG) emerges as an initiative of the scientific committee of the Spanish Society of Thoracic Surgery. We formulated PICO (patient, intervention, comparison, and outcome) questions on various aspects of spontaneous pneumothorax. For the evaluation of the quality of evidence and preparation of recommendations we followed the guidelines of the Grading of recommendations, Assessment, Development and Evaluation (GRADE) working group.

Usefulness of conventional pleural drainage systems to predict the occurrence of prolonged air leak after anatomical pulmonary resection.

Objectives: One of the reported advantages of digital pleural drainage system is the possibility of predicting the occurrence of prolonged air leak (PAL) based on the recorded pleural pressures and/or air flow through chest tubes. Nevertheless, this fact has never been well supported. The objective of this investigation is to evaluate if the occurrence of PAL can accurately be predicted using clinical data and air leak measurements 24 h after lung resection on conventional pleural drainage system (CPDS).

Poorer Survival in Stage IB Lung Cancer Patients After Pneumonectomy.

Objective: Pneumonectomy may be needed in exceptional cases in patients with early stage NSCLC, especially in stage IB. The aim of this study was to evaluate whether overall survival in stage IB (T2aN0M0) NSCLC patients is worse after pneumonectomy.

Methods: Retrospective study of a series of pathological IB (pIB) patients who underwent either lobectomy or pneumonectomy between 2000 and 2011.

Morbidity and mortality in octogenarians with lung cancer undergoing pneumonectomy.

Methods: Case-controlled retrospective analysis.

Effect of implementing the European guidelines for functional evaluation before lung resection on cardiorespiratory morbidity and 30-day mortality in lung cancer patients: a case-control study on a matched series of patients.

Objectives: We hypothesized that postoperative cardiorespiratory morbidity and/or 30-day death rates decreased after implementing the new European ERS/ESTS guidelines for functional evaluation before lung resection and tested the hypothesis by means of a case-control study.

Methods: The analysis included a series of 916 consecutive patients who underwent an anatomical pulmonary resection for non-small-cell lung cancer in our centre. Patients were divided into cases (September 2009-August 2012) and controls (December 2002-August 2009).

The risk of bilobectomy compared with lobectomy: a retrospective analysis of a series of matched cases and controls.

Objectives: Bilobectomy is considered to be a risky procedure due to space mismatch between the pleural space and the remnant lung. The objective of this study was to evaluate if postoperative complications related or not to size mismatch are more frequent after bilobectomy compared with right lobectomy cases.

Methods: Retrospective case-control study on a series of matched non-small-cell lung cancer patients.

Low-fat dairy products consumption is associated with lower triglyceride concentrations in a Spanish hypertriglyceridemic cohort.

Introduction: The first line of treatment for hypertriglyceridemic (HTG) includes a well-balanced diet, although the association of dietary components with triglyceride (TG) concentrations in hypertriglyceridemic patients is not fully understood.

Objective: To describe the main dietary patterns in a cohort of hypertriglyceridaemic patients and to evaluate the association between dietary components and TG levels.

Methods: This multicentre cross-sectional study included subjects (n = 1.

The risk of death due to cardiorespiratory causes increases with time after right pneumonectomy: a propensity score-matched analysis.

Objectives: The study aimed to compare in-hospital, 30-day and non-cancer-related 6-month death rates in a series of right and left pneumonectomy cases matched according to functional parameters.

Methods: A retrospective study was conducted on a series of 263 non-small cell lung cancer patients who underwent pneumonectomy. Left and right pneumonectomy cases were matched according to propensity scores using the following variables: age, coronary artery disease, any other cardiac comorbidity and predicted postoperative forced expiratory volume in the 1st second (ppoFEV1).

The values of intrapleural pressure before the removal of chest tube in non-complicated pulmonary lobectomies.

Objectives: Digitalized chest drainage systems allow for quantification of air leak and measurement of intrapleural pressure. Little is known about the value of intrapleural pressure during the postoperative phase and its role in the recovering process after pulmonary resection. The objective of this investigation was to measure the values of pleural pressure immediately before the removal of chest tube after different types of pulmonary lobectomy.

[Treatment of lung cancer with chest wall invasion].

The aim of this study was to analyze chest wall invasion, the indication and multidisciplinary nature of treatment, the methods used for parietal reconstruction and the technical problems posed by this procedure in patients with lung cancer and chest wall invasion. Chest wall invasion from adjacent malignancies affects 5% of patients with a bronchogenic carcinoma. Preoperative determination of parietal invasion aids the planning of an appropriate therapeutic approach.

Chest physiotherapy revisited: evaluation of its influence on the pulmonary morbidity after pulmonary resection.

Objective: The study aimed to evaluate if perioperative chest physiotherapy modifies the risk of pulmonary morbidity after lobectomy for lung cancer.

Methods: We have reviewed a prospectively recorded database of 784 lung cancer patients treated by scheduled lobectomy (361 operated after implementing a new physiotherapy program). No other changes were introduced in the patients' perioperative management during the study period.

A scoring system to predict the risk of prolonged air leak after lobectomy.

Background: Prolonged air leak (PAL) remains a frequent complication after lung resection. Perioperative preventative strategies have been tested, but their efficacy is often difficult to interpret due to heterogeneous inclusion criteria. The objective of this study was to develop and validate a practical score to stratify the risk of PAL after lobectomy.

Influence of major pulmonary resection on postoperative daily ambulatory activity of the patients.

To describe and compare the daily ambulatory activity of the patients before and one month after major lung resection. Daily activity was measured using a pedometer (OMROM Walking Style PRO) given preoperatively in a prospective way to a series of 21 consecutive cases scheduled for lobectomy or pneumonectomy. Analyzed variables were age, pulmonary function, mean number of total and aerobic steps per day, walked distance and mean daily time of aerobic activity.

Postoperative chest tube management: measuring air leak using an electronic device decreases variability in the clinical practice.

Objectives: Since there are no data in the literature regarding variability in the management of postoperative pleural drainages, we have designed a prospective randomized study aimed at measuring inter-observer variability in deciding when to withdraw chest tubes after lung resection and to evaluate if the use of an electronic device to measure postoperative air leak decreases clinical practice variations.

Methods: Sixty-one patients undergoing pulmonary resection were randomly assigned to one of the following groups: digital group (electronic measure of pleural air leak using Millicore AB DigiVent chest drainage system) or traditional group (standard water seal pleural chamber). Chest tube withdrawal criteria were established in advance.

Donor cryopreserved rib allografts for chest wall reconstruction.

Reconstruction after large chest wall resections must ensure not only anatomical coverage but a normal respiratory function, specially in the case of associated ventilatory disturbance. Since prosthetic reconstruction can present some problems such as rejection, excessive rigidity or infection, bone grafts have been proposed as an alternative to synthetic materials, due to their effectiveness and capability of integration with host tissues. Although iliac bone allograft or autologous ribs harvested from the opposite operative side are described for reconstruction, we present here the first reported clinical case of donor cryopreserved rib allografts use after extensive chest wall resection in a patient with severe COPD, showing excellent short-term results in the absence of pulmonary function impairment.

[Results of surgery for non-small cell lung cancer with N2 involvement unsuspected before thoracotomy].

Objective: To analyze survival in a group of patients with N2 involvement discovered during or after lung resection for non-small cell lung cancer and to evaluate the variables that affect survival.

Patients And Methods: The study included all patients with non-small cell lung cancer who underwent resection between January 1994 and October 2004 and in whom the definitive tumor classification was stage spIIIA due to N2 extension (n=74). Patients with stage spIIIB undergoing induction chemotherapy and patients for whom surgery was considered incomplete were excluded.

Reconstruction of chest wall defects after resection of large neoplasms: ten-year experience.

We review our experience in the treatment of complex large chest-wall defects needing a multidisciplinary approach due to primary or secondary neoplasms. Non-small cell lung cancer with chest-wall invasion cases are excluded. Fifteen patients underwent whole thickness resection of the chest wall due to lesions affecting at least three ribs, sternum, clavicle or thoracic spine and the surrounding soft tissue.

Effect of folic acid treatment on carotid intima-media thickness of patients with coronary disease.

Background: Carotid intima-media thickness (CIMT) is a surrogate marker of cardiovascular morbility. Hyperhomocysteinemia, which is an independent cardiovascular risk factor, is associated with low folate levels. The aim of this study was to evaluate the effect of folic acid treatment on the evolution of CIMT in patients with coronary disease and homocysteinemia > or =9 micromol/l.

Predicted versus observed FEV1 in the immediate postoperative period after pulmonary lobectomy.

Objective: Scanty information can be found regarding ppoFEV1% correlation with true FEV1% in the immediate days after surgery, when most cardio-respiratory complications are developed. This prospective multicentric investigation aims to describe the evolution of FEV1 in a series of uneventful lobectomy cases before hospital discharge, and to identify factors associated with the variation of postoperative residual FEV1, with the ratio between the actual and the predicted postoperative FEV1 measured during the first 6 postoperative days.

Methods: One hundred and sixty-one patients submitted to lobectomy were prospectively enrolled in the study.
