Surgical treatment of primary spontaneous pneumothorax with video-assisted thoracic surgery.

We report the results of our experience using video-assisted thoracoscopic surgery (VATS) to treat primary spontaneous pneumothorax (PSP) from January 1992 until December 1994 in a multicentered co-operative study. A total of 132 patients (110 males and 22 females, aged 13-38 yrs, mean age 26 yrs) were treated by VATS to deal with the PSP that they presented with. A standard VATS technique was used. Apical bullae were always removed, and mechanical pleural abrasion was performed, leaving a pleural drainage tube. In two cases (1.5%), a switch to thoracotomy was necessary. In eight cases (6%), air leakage persisted for 5 days after surgery, which resolved with pleural drainage. There were eight postoperative relapses (6%), which were treated with pleural drainage (n = 4), VATS (n = 3) or axillar thoracotomy (n = 1). The average postoperative stay was 5.6 days (range 2-15 days). We conclude that video-assisted thoracoscopic surgery is a viable alternative for the treatment of primary spontaneous pneumothorax. There is, however, a high relapse rate, and in a number of cases air leakage persists in the postoperative period.

Antibiotic prophylaxis in non-cardiac thoracic surgery: cefazolin versus placebo.

A total of 127 patients (57 given placebo and 70 given a single preoperative dose of 1 g cefazolin) undergoing thoracic surgery were included in a randomized double-blind trial. The two groups were similar in regard to mean age, sex ratio, in-hospital stay before surgery, underlying disease, risk factors, type of surgery, mean duration of surgical procedure, and mean duration of chest tube drainage. The relative risk of wound infection of the patients from the placebo group was 3.27 (range 1.5-11.5; 95% confidence interval). Cefazolin significantly reduced (p less than 0.01) the wound infection rate--1 case (1.5%) in the cefazolin group versus 8 cases (14%) in the placebo group--but not the incidence of postoperative pleural empyema--5 (7%) versus 8 cases (14%)--or nosocomial pneumonia--3 (4%) versus 5 cases (9%). Cultures were made from 3 out of 9 wound infections and Staphylococcus aureus or S. epidermidis was isolated in all 3. In addition, cultures were made from 6 out of 13 pleural cavity infections and S. aureus (1 case) or other microorganisms (5 cases) were isolated in all 6. Mortality was similar in both groups and all deaths unrelated to the infections. No adverse side effects of the drug were encountered. In conclusion, a single preoperative dose of 1 g cefazolin proved to be effective for reducing the wound infection rate in non-cardiac thoracic surgery.

Lung structure and gas exchange in mild chronic obstructive pulmonary disease.

To investigate the influence of pulmonary emphysema and small airways abnormalities on ventilation-perfusion (VA/Q) mismatching in mild chronic obstructive pulmonary disease (COPD), we studied 23 patients (mean predicted FEV1, 76 +/- 15%) before lung resection because of a localized neoplasm. Respiratory gas exchange and VA/Q distributions were measured while the patients breathed room air and 100% O2. Breathing room air, the AaPO2 was moderately increased (25 +/- 12 mm Hg) as was VA/Q mismatching, indicated by the dispersion (log SD) of both blood flow (Q) and ventilation (V) distributions (log SD Q, 0.78 +/- 0.3; and log SD V, 0.66 +/- 0.28, respectively) (normal range, 0.3-0.6). AaPO2, log SD Q, and log SD V all significantly correlated with the emphysema severity assessed morphologically from the resected lung specimens (r = 0.57, r = 0.62, and r = 0.45, respectively). Log SD V also significantly correlated with the severity of the inflammatory infiltrate of membranous bronchioles (r = 0.62). During 100% O2 breathing there was an increase in VA/Q mismatching (log SD Q rose to 1.12 +/- 0.08, p less than 0.001), suggesting release of hypoxic pulmonary vasoconstriction. This increase in VA/Q inequality was not significantly related to the severity of lung pathologic findings. We conclude that, in mild COPD, both pulmonary emphysema and small airways abnormalities contribute to VA/Q mismatch, the severity of emphysema being the major morphologic correlate of the increase in AaPO2.

VP-16 plus cyclophosphamide in the treatment of advanced lung cancer.

Ninety previously untreated patients with histologically documented lung cancer were treated with VP-16 and cyclophosphamide either alone (protocol I) or with methotrexate (protocol II) or Adriamycin (protocol III), with 30 patients in each protocol. The rates of objective response were 57,37, and 27%, respectively, protocol I being significantly better than protocol III (P less than 0.05). Protocol I was significantly less toxic than protocols II(P less than 0.01) and III (P less than 0.001). The overall rate of objective responses was 66% in small cell (SCC) and 22% in non-small cell carcinoma (nSCC). Median survival was 37 weeks in SCC and 21 weeks in nSCC. Median survival of responders both in SCC and in nSCC was significantly longer than in nonresponders. We conclude that VP-16 plus cyclophosphamide is a well tolerated regimen with positive effect in advanced lung cancer. The association of methotrexate or Adriamycin didn't offer any improvement over the basic combination in this study.

Outcome of patients after curative resection of pulmonary metastases.

BACKGROUND: Resective surgery can play a role in solitary pulmonary metastasis or in a few multiple metastases of the lungs. METHODS: We performed a retrospective analysis of the cure rate and survival in patients with pulmonary metastases after surgical resection. Inclusion criteria included no evidence of extrapulmonary metastases or local control of the primary neoplasia. Selective adjunctive therapy was added when applicable. RESULTS: Twenty-five out of 53 patients with resected pulmonary metastases are still alive and disease free. After a 5-year period of follow-up the cure rate obtained was 42%. CONCLUSIONS: In selected patients, resective surgery of solitary or limited multiple pulmonary metastases should be useful, offering the patients a high rate of curability and long term survival. These positive results suggest that adjunctive therapies should be added after resective surgery.
