Surgical treatment of bronchiectasis: early and long-term results.
No full textManagement of bronchiectasis remains controversial and information on long-term results of surgical treatment is poor. Clinical records of 45 patients, who underwent surgery for bronchiectasis in an 8-year period, were retrospectively reviewed. Bronchiectasis focus was isolated in 24 cases, associated with a limited homolateral or controlateral focus in 9 and 11, respectively; two patients had bilateral evident foci. Bronchiectasis was responsible for lobe destruction in 23 cases. All patients had symptoms: haemoptysis (n = 7), recurrent pneumonia (n = 7), persistent bronchorrea with recurrent infection (n = 15), hemoptysis and recurrent infection (n = 16). A total of 23 lobectomies, 11 lobectomies+segmentectomies, 2 bi-lobectomies, 9 segmentectomies and 1 pneumonectomy were carried out. There were no perioperative deaths; complications occurred in 5 patients (postoperative pneumonia in 2, prolonged air-leak, residual air-space and bronchial infection 1 each). Symptoms disappeared in 32 patients, 10 patients experienced a significant improvement. Exercise tolerance remained stable or improved in 33 and 2 cases, respectively, a slight impairment was observed in 9. Out of 32 evaluable patients 11 had an unchanged FEV 1, 15 had a limited FEV lowering (<15%), and 9 had a more important functional loss. Surgical treatment of bronchiectasis obtains satisfactory long-term results, with acceptable morbidity rates

Immediate and long-term results after surgical treatment of primary spontaneous pneumothorax by VATS
No full textBACKGROUND:
Video-assisted thoracic surgery has recently evolved as a viable alternative to thoracotomy for spontaneous pneumothorax.
METHODS:
A series of 163 patients with primary spontaneous pneumothorax were treated by video-assisted thoracic surgery. Seventy patients were treated for a recurrent episode, 64 patients for a persistent primary spontaneous pneumothorax, 24 patients for a contralateral episode, and 5 patients for a bilateral primary spontaneous pneumothorax. Stapling of bullae with an Endo-GIA stapler (Auto-Suture, Elencourt, France) was performed in 90% of the cases and parietal pleural abrasion was performed in each case.
RESULTS:
One revisional lateral limited thoracotomy was required for bleeding. Six patients had a prolonged air leak; 2 of them were reoperated on by lateral limited thoracotomy. Two patients have had an incomplete reexpansion of the lung and required a reoperation. The duration of hospitalization was 6.9 +/- 3 days. With a mean follow-up of 24.5 months, three recurrences requiring a reoperation occurred; 3 other patients had a partial recurrence and healed by rest without drainage. The mean time to return to the occupational activity of the patients was 42 +/- 34 days. These results were compared with those of a previous series of 87 patients operated on by lateral limited thoracotomy.
CONCLUSIONS:
With the development of surgical technique and video equipment, video-assisted thoracic surgery will probably become the treatment of choice of primary spontaneous pneumothorax
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Resection for tumors with carinal involvement : technical aspects, results, and prognostic factors
No full textBackground. Resection of tumors with carinal involvement remains a challenge because of specific problems of operative technique and airway management. We reviewed our experience with carinal resection and studied factors influencing postoperative course and long-term survival. Methods. Between 1983 and 2002, 65 patients underwent a carinal resection for non-small-cell lung cancers involving the carina (54 squamous cell carcinomas and 11 adenocarcinomas). Results. Fifty-eight right sleeve pneumonectomies and 2 left sleeve pneumonectomies were performed. In addition, five tracheocarinal resections with double bronchial reimplantation (no lung resection) were also performed. The intraoperative airway management consisted of high-frequency jet ventilation in 83% of patients and intermittent conventional ventilation through the operative field in the remaining 17% of patients. Operative mortality was 7.7%. Resection was complete in 61 patients. The overall 5-year and 10-year survival rates were 26.5% and 10.6%, respectively. Patients with NO or N1 disease had a 5-year survival of 38% compared with 5.3% for those with N2 disease (p < 0.01). At multivariate analysis only nodal status (NO, N1 versus N2; p = 0.0046) had a significant impact on long-term survival. Conclusions. Carinal resection provides acceptable results in terms of operative mortality and long-term survival rates. Patients should be carefully selected and probably enrolled in a multimodality treatment program in case of anticipated mediastinal lymph node involvement
