Abstract
Extracorporeal membrane oxygenation (ECMO) is used in severe respiratory failure to maintain adequate gas exchange. So far, this technique has not been commonly used in general thoracic surgery. We present a case using ECMO for peri-operative airway management for pulmonary resection, using a novel single-site, internal jugular, veno-venous ECMO cannula.

Abstract
INTRODUCTION AND METHODS The impact of the volume of activity and the specialisation of the surgeon and the hospital on the quality of health care for patients with non-small cell lung cancer (NSCLC) was evaluated from the publications over the last 20 years. RESULTS The statistics, based mainly on administrative data, identified a significant decrease in post operative mortality (5 out of 7 studies) and improved long-term survival (2 out of 3 studies) in establishments undertaking large numbers of lung resections. The threshold for defining high volume groups varied from study to study (from 28 to 128 procedures per year). The same tendency was seen among the surgeons where specialisation in thoracic surgery led to higher levels of resectability and parenchymal preservation. CONCLUSIONS These results should be interpreted with caution on account of the nature of the data and the methodology employed. A certification of referral centres, validated by the French Thoracic and Cardiovascular Surgical Society, based on the training, level of activity in cancer surgery, and the infrastructure of the hospital should lead to a more even standard of care for patients with NSCLC.

Abstract
A quadriplegic patient experienced post-traumatic exteriorisation of the subcutaneous receiver of a phrenic pacemaker. In the absence of infection and stimulation dysfunction in the patient, the device was reimplanted with full success at 1 year. This strategy can, exceptionally, be considered if removal and subsequent implantation is impossible or refused.

Abstract
BACKGROUND Despite an early-stage diagnosis, lung cancer presenting with visceral pleura invasion (VPI) or malignant pleural lavage cytology (PLC) has a poor prognosis. The purpose of this study was to correlate VPI to malignant PLC. METHODS One hundred forty-three consecutive patients scheduled for surgical lung resection having undergone preresectional pleural lavage cytology were reviewed. There were 121 malignant and 22 nonmalignant lesions. All cases were studied by pathology, histology, previous transthoracic puncture, VPI, and presence of pleural lymphatic involvement. RESULTS PLC was positive (n = 13) or suspected (n = 5) for malignant cells in, respectively, 10.7% and 4.1% of patients with lung cancer. There was no positive PLC in cases of nonmalignant disease. PLC was positive only in pT2 tumors and almost always when the tumor was exposed on the pleural surface, thus possibly exfoliating within the pleural space (12/17 patients, 70.6%; p < 0.01). Positive PLC was obtained whatever the histology but did not appear related to previous transthoracic puncture or involvement of pleural lymphatics by tumor cells. CONCLUSIONS VPI and positive PLC are linked, and the appearance of tumor cells within the pleural cavity can be explained by tumor desquamation. The role that visceral pleura involvement and parietal pleura reabsorption play in lung cancer is of paramount importance and deserves further research. A better understanding of their relationship could have major implications in the therapeutic management of non-small cell lung cancer.

Abstract
Most of the studies on lung cancer and age are usually done on very young or very old populations. We conducted a study of the evolution of surgical features over time in a population aged 24 to 89 years. The series included 1,809 men and 287 women (n = 2,096) who had undergone surgery between April 1984 and December 1990 (n = 1,026) and between January 1991 and December 1996 (n = 1,996). Patients were divided into 7 age groups with 2 subgroups for patients with or without prior medical history of cancer. We analyzed the type of surgery and pathology findings by age. Morbidity was recorded according to state of previous cardiovascular disease and long-term survival was analyzed. A significant increase in the number of female patients was noted during the last ten years. Adenocarcinomas were more frequent in young patients. Exploratory interventions, partial tumor resections and lung resections for metastasis were more frequently performed in young patients than in older patients. Excision of mediastinal nodes was less performed often in old patients. In case of curative resection, postoperative pTNM was not modified with age. Morbidity increased with age; mortality was more frequent in the elderly even when comorbidity was taken into account. Mortality was not related significantly with cardiovascular morbidity factors despite an increased frequency of previous cardiovascular disease with age. Survival according to age showed 3 main types of population: patients aged under 64 years, those between 65 and 74, and those over 75 years of age. Mortality increased with time but was less often related to recurrence of lung cancer. Nevertheless, survival for stage III and stage IV patients older than 75 years demonstrated that surgery was not indicated for these patients. This study shows that indications for surgery should not vary with age except for patients over 75 years who have locally advanced cancer and a risk of surgical death greater than the chances of survival. All non-small-cell lung cancers should be resected with no delay, even in the elderly population.

Abstract
In its anatomy and physiology the pig is comparable with humans and its organs can be considered for xenotransplantation. We have studied the lymphatic drainage of the heart and lungs in 15 pigs. A coloured mass was injected into the myocardium and/or beneath the visceral pleura. The first nodes coloured were directly injected again. No lymph node was observed inside the heart and lungs. The first lymph nodes coloured were the peritracheobronchial nodes. There was no node in front of the thoracic trachea (Barety's compartment in man). Left suprabronchial nodes were connected with the thoracic duct in the mediastinum. The lymphatics of the heart and lungs in the pig are similar to those of human. Phylogenesis explains "skipping" metastases and the significance of N1 disease in lung cancer, as well as chylothorax occurring after heart and lung surgery.

Abstract
Thoracic empyemas may occur during the course of lung cancer as a post-thoracotomy complication, or after pleural drainage and/or chemotherapy in cases when surgery was unfeasible, or may complicate the natural history of the disease and appear as the clinical event that led to its discovery. This latter situation is a challenge requiring to cure the infection in order to further treat the underlying lung cancer. We reviewed the cases of 18 men aged between 46 and 79 years that were referred to our surgical department from 1984 to 1996 for management of a thoracic empyema with an underlying lung cancer. Initial presentation of empyemas, lung tumor characteristics, treatments performed and their results were analyzed so as to formulate guidelines if possible. Mean duration of 17 empyemas before arrival was 26 days (8 to 60 days) and in one case empyema occurred during diagnostic work-up of an excavated lesion. Frank pus was observed in all cases and micro-organisms were identified in 13 cases. Empyema and diagnosis of lung cancer were concomitant in 15 cases: in 3 cases lung neoplasia was already diagnosed but patients had refused surgery. Empyema was treated by under water-seal chest tube drainage with adjunct fibrinolytic therapy in all cases; 2 elderly and cachectic patients suffering metastatic diffusion died rapidly. The other 16 recovered within one month. In 7 cases management was limited to medical treatment (palliative n = 2, chemotherapy n = 1, chemo combined radiotherapy n = 2 and radiotherapy alone n = 2) but only short survivals were observed (inferior to 10 months). Surgery was possible in 9 (pneumonectomy n = 8, lobectomy n = 1); there was no death; postsurgical empyemas complicated the cause twice but were easily cured by drainage; long term survivals were observed in 3 cases that were p NO. Pleural empyema complicating lung cancer is a rare but challenging situation. Once the pleural empyema has been controlled, surgical resection must be performed when indicated: postoperative complications are rare and long-term survival is possible.

Abstract
The aim of this study was to describe in detail the anastomoses between the pulmonary lymphatic vessels and the veins of the neck so as to better understand their role in certain aspects of thoracic surgery. The lymphatic vessels of 687 pulmonary segments in 360 cadavers were injected. A detailed study of the proximal end of the right paratracheal, right tracheo-esophageal, left preaortocarotid and left recurrent lymph node chains was undertaken. The results showed the absence of any major right lymphatic "vein". There were, however, many lymphatic arches draining into the jugulo-subclavian confluence ipsilaterally, and, in 10 to 15% of cases, contralaterally as well. The intertracheobronchial lymph nodes also drained into the venous confluence of the neck via direct lymphatic vessels, without lymph node relays. Finally, the left mediastinal lymph node chains were frequently found to drain into the arch of the thoracic duct (40% of cases), and reflux due to valvular incompetence at this level may account for chylous pericarditis and some cases of chylothorax after surgery.

Abstract
Isolated acquired factor VII (FVII) deficiency (0.15 U/ml) was identified in a 30-year-old man with pleural liposarcoma. The patient underwent surgery with continuous FVII concentrate infusion. No anti-FVII antibody or FVII/anti-FVII complex was detected. However, the short half-life and low recovery of FVII after concentrate infusion suggested the presence of an antibody. Whatever the mechanism, this FVII deficiency was related to the presence of the liposarcoma. FVII level normalized during tumour regression and fell again when the liposarcoma relapsed.

Abstract
The authors report 4 cases of intrathoracic extrapulmonary pneumocystosis; 3 of them involved the pleura and 1 the mediastinal lymph nodes. As in other rare but apparently increasingly frequent cases, everything seemed to incriminate the use of prophylactic Pentamidine aerosols, but only a prospective study of systemic versus aerosol prophylaxis can confirm this suspicion.

Abstract
The multiplicity of potential causes of variations in mixed venous oxygen saturation (SvO2) during one lung ventilation (OLV), including a constant ventilation/perfusion mismatch, explains that it has been suggested as a routine monitoring procedure. To assess its usefulness, 12 adults undergoing OLV were monitored during surgery with an Oximetrix pulmonary catheter, placed on the side opposite to the surgical field under fluoroscopic control. Seventy two complete sets of haemodynamic measurements were obtained at 6 different times during surgery. We studied the ability of changes in SvO2 to predict changes in arterial oxygen saturation (SaO2), cardiac output (CO), and venous admixture (VA) by calculating sensitivities (Se), specificities (Sp) and predictive values with regard to these variables. There were no complications due to the protocol. However left-sided catheter placement failed in four cases. Correlation between optical and measured SvO2 was very strong (r = 0.94; p less than 0.001). SvO2, oxygen consumption (VO2) and the rate of oxygen extraction remained constant throughout the procedure, even when CO, mean arterial pressure, VA, SaO2 and PaO2 varied. Clamping the pulmonary artery returned VA, SaO2 and PaO2 values to those found before OLV, but produced a significant decrease in CO. SvO2 had low Se and Sp for changes in other variables (CO: 76 +/- 7, 48 +/- 9; PaO2: 79 +/- 6, 59 +/- 9; VA: 54 +/- 7, 48 +/- 7 respectively). In this type of surgery, alterations in variables related to oxygen are probably balanced by haemodynamic changes. In fact, according to Fick's formula, SvO2 is almost completely determined by SaO2 and CO, when VO2 and haemoglobin remain stable.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
The clinical effects of methohexital versus thiopental are studied in 60 randomized patients anaesthetized for E.N.T. endoscopy or laser surgery of the larynx. Thiopental is injected by I.V. bolus (5 mg/kg) and methohexital is administered by continuous infusion (0.1 mg/kg/min). Fentanyl is the analgesic and succinyl-choline is used for curarisation. All patients are ventilated by a conventional ventilator or by high frequency ventilation. Side-effects, extubation time, and recovery estimated by the Newman-test modified by Weber are studied. The only difference between methohexital and thiopental is a better recovery-score at 30 minutes for the methohexital group.

Abstract
Obstruction of a major bronchus by a benign lesion can be accompanied by a functional reduction of the perfusion of the distal lung. This disorder is reversible after removal of the obstruction. We present 5 cases of obstruction of a main bronchus with functional exclusion of the affected lung on scintigraphy. The obstructing lesion was carcinoid tumour in 4 cases and a plasmocytic granuloma in another case. The perfusion was found to be restored following the operation (one bronchotomy, three isolated resection-anastomoses and one resection-anastomosis with lobectomy). These disorders are due to reflex phenomena and anatomical modifications related to the trapping effect. These phenomena are revealed by plain chest x-rays and by perfusion and ventilation pulmonary scintigraphy.
