The longitudinal impact of division-wide implementation of an enhanced recovery after thoracic surgery programme.

OBJECTIVES: Data regarding enhanced recovery after thoracic surgery (ERATS) are sparse and inconsistent. This study aims to evaluate the effects of implementing an enhanced ERATS programme on postoperative outcomes, patient experience and quality of life (QOL). METHODS: We conducted a prospective, longitudinal study evaluating 9 months before (pre-ERATS) and 9 months after (post-ERATS) a 3-month implementation of an ERATS programme in a single academic tertiary care centre. All patients undergoing major thoracic surgeries were included. The primary outcomes included length of stay (LOS), adverse events (AEs), 6-min walk test scores at 4 weeks, 30-day emergency room visits (without admission) and 30-day readmissions. The process-of-care outcomes included time to 'out-of-bed', independent ambulation, successful fluid intake, last chest tube removal and removal of urinary catheter. Perioperative anaesthesia-related outcomes were examined as well as patient experience and QOL scores. RESULTS: The pre-ERATS group (n = 352 patients) and post-ERATS group (n = 352) demonstrated no differences in demographics. Post-ERATS patients had improved LOS (4.7 vs 6.2 days, P < 0.02), 6-min walk test scores (402 vs 371 m, P < 0.05) and 30-day emergency room visits (13.7% vs 21.6%, P = 0.03) with no differences in AEs and 30-day readmissions. Patients experienced shorter mean time to 'out-of-bed', independent ambulation, successful fluid intake, last chest tube removal and urinary catheter removal. There were no differences in postoperative analgesia administration, patient satisfaction and QOL scores. CONCLUSIONS: ERATS implementation was associated with improved LOS, expedited feeding, ambulation and chest tube removal, without increasing AEs or readmissions, while maintaining a high level of patient satisfaction and QOL.

Assessment of Operability and Resectability in Lung Cancer.

Lung cancer is a lethal disease, and chronic cigarette smoking is the most common cause. The selection of treatment is based on the histologic cell type, accurate staging, and adequacy of cardiopulmonary functional reserve. The risk for surgery is highest in patients over the age of 80 years.

Guiding Principles on the Importance of Thoracic Surgical Education on Establishing Integrated Thoracic Surgery Program, Interdisciplinary Thoracic Oncology Conferences, and an Interdisciplinary Approach to Management of Thoracic Malignancies.

The objective of these notes is to stress the principles underlying the management of primary lung cancers and other types of malignancies in the thorax-diffuse malignant mesothelioma, invasive mediastinal tumors, chest wall sarcoma, and tracheal neoplasms-and from these considerations to outline a routine scheme for management, which can be followed easily by all staff. It is hoped that by adherence to this routine, adequate and efficient management of all cases will be obtained, both in the very important matter of preoperative preparation, as well in the postoperative management.

Sepsis in the Postpneumonectomy Space: Pathogenesis, Recognition, and Management.

Empyema may occur in the pleural space after pulmonary resection. Subsequent bacterial contamination results in infection and development of frank empyema. Pneumonectomy-surgical removal of the entire lung-is the treatment of choice for centrally located bronchogenic carcinoma, diffuse malignant mesothelioma, and chronic inflammatory lung diseases with destroyed lung from pulmonary tuberculosis, fungal infections, and bronchiectasis. In the uncomplicated case, on the pneumonectomy side, the diaphragm becomes elevated as the air-fluid level decreases with chest wall deformation and gradual disappearance of hydrothorax. The pneumonectomy space is at potential risk for getting infected from bacterial contamination and developing empyema.

The Lymphatic Spread of Lung Cancer: An Investigation of the Anatomy of the Lymphatic Drainage of the Lungs and Preoperative Mediastinal Staging.

The knowledge of lymphatic spread of lung cancer permitted the study of anatomy of lymphatic drainage of the lungs. The history of anatomy of lymphatic drainage of the lungs began in the 15th century. In the human, pulmonary lymph flows to the lymph nodes around the lobar bronchi and thence to extrapulmonary lymph nodes located around the main bronchi and trachea and its bifurcation (tracheobronchial lymph nodes). These send their efferents to a right and left mediastinal lymph trunks, which may join the thoracic duct, but usually drain opening directly into the brachiocephalic vein of their own side.

Superior Vena Cava Resection and Reconstruction with Resection of Primary Lung Cancer and Mediastinal Tumor.

The superior vena cava is a short ∼7-cm valveless vessel that brings blood from the upper half of the body to the heart but has connections to the infracardiac venous structures as well. It can become obstructed, mostly by advanced lung cancer but benign conditions account for one-fourth of cases. When possible, reconstruction can be by biological material or via ring reinforced grafts. When perfomed, replacement should be with small caliber grafts to allow for rapid flow of blood, which, with the addition of anticoagulants, reduces the risk of thrombosis. Even with advanced malignancy, treatment may confer reasonable survival.

Standardized Postoperative Adverse Event Data Collection to Document, Inform, and Improve Patient Care.

There is great potential for standardized postoperative adverse events data collection to document, inform, audit, and feedback, all to optimize patient care. Adverse events, defined as any deviation from expected recovery from surgery, have harmful implications for patients, their families, and clinicians. Postoperative adverse events occur frequently in thoracic surgery, predominately due to the high-stakes (ie, high potential for cure) and high-risk (ie, vital physiology and anatomy and preexisting disease) nature of the surgery. As discussed, engaging surgeons in audit and feedback practices informed by standardized data collection would generate consensus recommendations to reduce adverse events and improve patient outcomes.

Controversies in Lung Cancer: When to Resect with Compromised Pulmonary Function.

Lung cancer is the most common cause of cancer-related death worldwide among both men and women. Patients with lung cancer frequently have impaired pulmonary function, usually secondary to smoking-related chronic obstructive lung disease. Numerous techniques have been used to evaluate the postsurgical risk. These techniques include preoperative pulmonary function test, 6-minute walk test, stage 1 cardiopulmonary exercise test, 2D echocardiography, and quantitative ventilation-perfusion scintigraphy.

The History and Evolution of Surgical Instruments in Thoracic Surgery.

Surgery is as old as man, and its evolution has been moulded in every age by current technical and scientific advances, not forgetting the demands made upon it by social circumstances and religion. It is both an art and a science, while its practice largely depends on the human relations between doctor and patient. It is extremely difficult to define where surgery begins or ends, and its separation from medicine is largely based on the very different paths which the two disciplines took in ancient times.

Paraneoplastic Syndromes in Lung Cancers: Manifestations of Ectopic Endocrinological Syndromes and Neurologic Syndromes.

Paraneoplastic syndromes are clinical entities associated with cancers and often overlap with metabolic and endocrine syndromes. The cell types of lung cancer involved are frequently small cell, squamous cell, adenocarcinoma, large cell, and carcinoid tumor. A number of neurologic paraneoplastic syndromes have been described for which the tumor product remains unknown. These include peripheral neuropathies, a myasthenia-like syndrome, and subacute cerebellar degeneration. Although all of these syndromes may improve with successful treatment of the primary tumor, complete resolution is rare.

Delays in Managing Lung Cancer: The Importance of Fast-Tracking in the Clinical Care.

Early diagnosis in lung cancer is desirable, because surgical resection offers the only hope of cure. In the face of suggestive symptoms, a normal plain chest radiograph does not exclude the diagnosis, and investigation is essential. The various imaging changes seen on computerized tomography and PET scan provide strong suggestive evidence of lung cancer, but proof of diagnosis rests on histologic examination, material that may be obtained by one of the following diagnostic procedures: bronchoscopy, mediastinoscopy, fine needle aspiration biopsy, thoracentesis and pleural biopsy, lymph node biopsy, and exploratory thoracotomy.

Medical Audit to Improve the Quality of Patient Care in Thoracic Surgery.

The purpose and conduct of medical audit is a means of quality control for medical practice by which the profession shall regulate its activities with the intention of improving overall patient care. The quality assurance depends on patient and physician satisfaction. The medical profession needs to be educated about the structure, process, and outcome. The structure equates to resources found within the hospital. The outcome is when quality of care becomes preeminent.

How to Design and Foster Thoracic Oncology Multidisciplinary Cancer Conferences.

In this chapter, the authors review and discuss the literature on multidisciplinary cancer conferences (MCCs, aka tumor boards), clarifying the terminology, showing the evolution of the field, and providing an evidence-based perspective on positive outcomes, best practices, factors influencing the quality of MCCs, evaluation tools to assess the quality of MCCs, and quality improvement interventions for MCCs. The authors then discuss some perspectives from their MCC and initiatives that they undertook to improve the work of their team and the care that they provide to patients in the area of thoracic oncology.

Role of the Thoracic Radiologist in the Evaluation and Management of Solid and Subsolid Lung Nodules.

In this review, the authors describe the imaging characteristics of solid and subsolid nodules as well as their management recommendations including the use of image-guided percutaneous biopsy and preoperative coil localization. Using case presentations, they offer practical management tips for the most commonly encountered nodule nodules in a thoracic surgical practice.

Oligometastatic Lung Cancer Defined by Biology, Science, and Secondary Growths.

Breast cancer was the first malignant tumor for which TNM classification was proposed by the International Union Against Cancer. Volume and distribution of tumor burden were considered clinically important in this cancer. Lung cancer is caused by excessive cigarette smoking. Prognosis is worst in small cell lung cancer and in non-small cell lung cancer measuring over 3 cm in size and having regional lymphatic spread. Metastatic spread from lung cancer is favored by lymphatic spread to the locoregional lymph nodes and blood-borne spread to 5 sites-lung, brain, bone, liver, and adrenal-all of which are unfavorable prognostic indicators.

Ethics for Thoracic Surgeons in the Management of Lung Cancer.

Lung cancer is a terrible disease, with less than 20% of patients with a diagnosis of lung cancer able to have a resection but many relapsing, making it one of the most biologically aggressive cancers known. Thoracic surgeons do not see all the other 80% but are often consulted and have to make recommendations, and sometimes have to intervene. Thoracic surgeons should be well informed about the ethical framework and participate actively in the discussion. Ethics is an important aspect of surgical practice and has implications for patients, surgeons, and surgical teams, as well as for society.

Can Biologic Aggressiveness and Metastatic Potential of Primary Lung Cancer Be Predicted from Clinical Staging Alone?

The future biologic aggressiveness and metastatic potential of lung cancer, as in other cancers, cannot be predetermined from the current clinical information, imaging studies, and pathologic examination whose purpose is to provide diagnosis and mutation studies and molecular drivers only in making decision for treatment. There is a need for better understanding of the biologic characteristics and aggressiveness of lung cancer. The most that is achieved from clinical staging and pathologic staging is in the planning of treatment of lung cancer and predicting prognosis. Aggressive biologic behavior to come is not within the domain of clinical staging or pathologic staging.
