Hospital volume: operative morbidity, mortality and survival in thoracotomy for lung cancer. A Spanish multicenter study of 2994 cases.

INTRODUCTION: It has been hypothesized that medical procedures performed in high-volume units carry less risk and achieve a better outcome. OBJECTIVE: To determine the relationship between the number of interventions and the operative morbidity, mortality and long-term survival in the surgery of bronchogenic carcinoma (BC). PATIENTS AND METHOD: Prospective, multicenter Spanish study was conducted in 19 departments of thoracic surgery on 2994 patients operated on consecutively with the aim of curing BC. The thoracic surgery departments have been classified into three groups, according to the number of interventions performed per year: I (1-43 cases/year; centers=7; n=565; 18.9%), II (44-54 cases/year; centers=6; n=1044; 34.9%) and III (55 or more cases/year; centers=6; n=1385; 46.3%). RESULTS: When the three groups were compared, the frequency of complete surgery was found to be 84% for group I, 76% for group II and 83% for group III (p=0.001, for comparisons between groups I/II and II/III). The pathological stages were identical in the three groups. The overall morbidity and the mortality in all patients or above the age of 75 or in pneumonectomies were not different among the groups. When considering all the patients with prognostic information (n=2758), no differences were found regarding the 5-year survival among the groups. When only patients in postoperative stage I-II and complete resection were evaluated, excluding operative mortality (n=1128), 5-year survival was 0.58 for group I, 0.57 for group II and 0.50 for group III (p=0.06 between groups II and III; p=0.08 between groups I and III). CONCLUSIONS: No significant differences that do not favor the hypothesis that there is increased surgical risk and worse survival in centers having a lower volume were found in this Spanish multicenter study.

Axillary thoracotomy versus videothoracoscopy for the treatment of primary spontaneous pneumothorax.

BACKGROUND: A prospective, randomized study was carried out on patients with primary spontaneous pneumothorax, with the aim of determining if video-assisted thoracoscopy is superior to axillary thoracotomy in the surgical treatment of this condition. METHODS: Patients were randomly assigned to two groups; video-assisted thoracoscopy (group A; n = 46) and axillary thoracotomy (group B; n = 44). All fit the established criteria for surgical indication (relapse or persistent air leakage after pleural drainage). In all cases the treatment consisted of apical segmentectomy of the blebs or dystrophic complex and pleural mechanical abrasion. The study evaluated the following factors: postoperative blood loss, respiratory function (maximum inspiratory and expiratory pressures, forced expiratory volume in the first second and forced vital capacity), postoperative pain (analog visual scale), supplementary doses of analgesics, postoperative complications, hospital stay, and resumption of normal activity. Relapses were evaluated for the minimum period of time of two years. RESULTS: No significant differences were found in any of the factors studied in either group. CONCLUSIONS: Video-assisted thoracoscopy and axillary thoracotomy offer similar results in the surgical treatment of primary spontaneous pneumothorax. The rate of complication is low and the level of pain is acceptable without long-term sequelae.

Esophagobronchial fistula caused by traction esophageal diverticulum.

Fistulization is a rare and not often described complication of esophageal diverticula. We present the case of a patient treated surgically in our service who had a history of diverticulum of the third distal of the esophagus, and was diagnosed for irritative post-ingestive cough with associated regurgitation and vomiting of undigested food.

Role of surgery in pulmonary tuberculosis.

BACKGROUND: The purpose of our study was to analyze current indications for surgery in tuberculosis (TB). We present our experience with TB patients presenting with indications for surgery between 1990 and 1998. MATERIAL/METHODS: The indications for surgical intervention included 25 cases of pulmonary aspergilloma, 19 cases of pneumothorax, 16 cases of pulmonary nodes and masses without histological diagnosis, 15 cases of bronchiectasis, 12 cases of massive hemoptysis, 12 cases of pleural empyema, and 33 cases of other complications. No patients with multidrug-resistant tuberculosis required surgical intervention, although 56 were treated during this period. RESULTS: The techniques utilized included lobectomy in 45 cases, pleural drainage in 32 cases, segmented pulmonary resection in 32 cases, surgical procedures on the thoracic wall in 17 cases, pneumonectomy in 10 cases, pleuropulmonary decortication in 8 cases, mediastinoscopy in 6 cases, and thoracoscopy in 5 cases. In 25 cases two or more procedures were performed on the same patient. In 36 cases (27.3%) there were complications, of which persistent air leakage after pulmonary resection was the most frequent (n=10). There was a mortality rate of 5.3% (7 CONCLUSIONS: In our experience, surgery in the treatment of TB is indicated to resolve sequelae or complications, since cases of simple or multidrug-resistant TB can be managed pharmacologically. The morbidity and mortality rates in our series were acceptable.
