[Analysis of risk factors for development of bronchopleural fistula after pneumonectomy for lung cancer].

Bronchopleural fistulas (BPF) developed in six (7.9%) of 76 patients who underwent a pneumonectomy for treatment of lung cancer. Five patients (18.2%) underwent a right pneumonectomy and one (3.7%) a left pneumonectomy. All patients were male, had squamous cell carcinoma, and were diagnosed as having BPF within one month after pneumonectomy. Their average age was 60.2 years. Univariate analyses related to development of BPF showed that significant risk factors were preoperative infection (Chi-square test; p < 0.001), right pneumonectomy (Chi-square test; p < 0.05), and metastasis to a subcarinal lymph node (Chi-square test; p < 0.05). However, sex, age, operating time, amount of blood loss during surgery, amount of blood transfused during surgery, history of smoking, degree of lymph node dissection, degree of curability, performance of combined resection, histologic type of tumor, tumor size, presence of residual tumor at the bronchial stump, and suturing method were not significant risk factors for development of BPF. Our stepwise regression analysis related to development of BPF showed that preoperative infection, metastasis to a subcarinal lymph node, right pneumonectomy, and combined resection were significant risk factors. Sometimes it is difficult to preserve the bronchial arteries upon the dissection of metastatic subcarinal lymph nodes which tightly adhere to the bronchial sheath. Moreover, after a conventional right pneumonectomy, the bronchial stump protrudes into the pleural cavity and is not covered by any tissue. Ligation of the bronchial arteries or protrusion of the bronchial stump into the right pleural cavity reduces the blood supply to the bronchial stump to a very low level and causes development of BPF. Therefore, we suggest that control of preoperative infection, wrapping of the bronchial stump, and preservation of the bronchial arteries during mediastinal lymph node dissection are important to prevent development of BPF.

[Quality of life after pneumonectomy for bronchial carcinoma].

UNLABELLED: Quality of life measurements gained increasing importance in the last years. After lung tissue reducing interventions for bronchogenic carcinoma quality of life measurements play an important role, since quality of life can be decisively influenced by post-operative reduced lung function. On the basis of postoperative physical symptoms and lung function the restriction of quality of life after pneumonectomy should be analyzed with respect to intervention and adjuvant therapy, 36 patients with an average age of 61 years were followed up by ambulatory oncological care for 40 months (median) after operation and lung function as well as quality of life were measured by self assessment index QLQ- C 30 of EORTC. RESULTS: Beside physical symptoms (increasing of dyspnea by 61.1% and pain by 30.6% after pneumonectomy as compared to preoperative values) the significant reduced lung function (IVC by 33.5%, FEV 1 by 27.1%) and the QL-measurement showed the greatest restrictions, latter in "Physical functioning" by 27.2%, in "Role functioning" by 45.8% and in "Global health status/ Quality of life" by 45.6%. The symptoms "Fatigue" (Score 39.8), "Dyspnea" (50,9), "Pain" (29.6) and "Sleep disturbance" (35.2; max. score 100 = high frequency) were most often found. Further adjuvant therapy (at least 6 months after completion) in 11 patients and the type of pneumonectomy (right-side: n = 11, left-side: n = 25) did not result in additional significant reduction of lung function and of single quality of life dimensions, except that "Dyspnea" in patients with right-sided pneumonectomy (66.7) was significantly more frequent than in patients with left-sided pneumonectomy (44.0). CONCLUSIONS: In this study the restricted quality of life after pneumonectomy was mainly caused by reduction of cardiopulmonary function (reduced lung function by loss of parenchyma). Adjuvant therapy reduced neither lung function nor quality of life. Compared to quality of life measurements after lung resection [17] quality of life after pneumonectomy didn't worse.

Determinants of perioperative morbidity and mortality after pneumonectomy.

A total of 197 consecutive patients undergoing pneumonectomy at the M.D. Anderson Cancer Center from 1982 to 1987 were reviewed. Sixty-five variables were analyzed for the predictive value for perioperative risk. The operative mortality rate was 7% (14/197). Patients having a right pneumonectomy (n = 95) had a higher operative mortality rate (12%) than patients having a left pneumonectomy (1%, p less than 0.05). The extent of resection correlated with the operative mortality rate (chest wall resection or extrapleural pneumonectomy, n = 39, 15%; versus simple or intrapericardial pneumonectomy, n = 158, 5%; p less than 0.05). Patients whose predicted postoperative pulmonary function, by spirometry and xenon 133 regional pulmonary function studies, was a forced expiratory volume in 1 second greater than 1.65 L, forced expiratory volume in 1 second greater than 58% of the preoperative value, forced vital capacity greater than 2.5 L, or forced vital capacity greater than 60% of the preoperative value had a lower operative mortality rate (p less than 0.05). Atrial arrhythmia was the most common postoperative complication (23%). Xenon 133 regional pulmonary function studies are useful in predicting the risks of pneumonectomy.

Pneumonectomy after contralateral lobectomy: is it reasonable?

Conservative resection of a second primary lung cancer is desirable but not always feasible. We recently carried out three left pneumonectomies for the removal of metachronous primary lung cancers in patients who had previously undergone right upper lobe resection for the treatment of bronchogenic carcinoma. In each patient, the results of pulmonary function tests plus the findings from quantitative perfusion lung scans predicted a postpneumonectomy forced expiratory volume in 1 second of at least 1.00 L. All 3 patients had uncomplicated postoperative courses, and were doing satisfactorily at follow-up 2 to 6 months later. One patient died 5 months after pneumonectomy due to unrelated causes, another died 8 months after pneumonectomy from infection after resection of a brain metastasis, and the third is doing well 15 months after pneumonectomy. The rarity of previously reported cases suggests that performing a pneumonectomy after contralateral lobectomy may be considered too radical. Our experience indicates the procedure may be considered if the patient's pulmonary function meets the standard criteria for pneumonectomy.

Bronchopleural fistula after pneumonectomy with a hand suture technique.

We have reviewed the incidence of bronchopleural fistula among 530 consecutive pneumonectomies, all carried out by one surgical team using a uniform suture technique between January 1980 and November 1993. There were 7 fistulas (1.3%); all of them occurred within 15 days postoperatively. There were no cases of late fistula during a mean follow-up period of 23 months. The pathology for which pneumonectomy was undertaken was primary lung malignancies in 488 cases (92.1%), metastatic disease in 15 cases (2.8%), and benign diseases in 27 cases (5.1%). All fistulas developed after pneumonectomy for lung cancer. Other risk factors included age, preoperative radiotherapy, and the surgeon's level of experience, as only two fistulas occurred with the consultant who performed 410 pneumonectomies (0.5%). The bronchial stump was free of tumor in all cases. There were no fistulas in the 37 completion pneumonectomies (7%). All fistulas were treated within 2 days of diagnosis by resuturing the stump through the initial thoracotomy incision. That was successful in 5 patients, whereas fatal complications developed in the other 2 patients. We believe that suture closure of the bronchial stump at pneumonectomy provides a cheap and reliable technique that gives good results in all situations.

Sleeve lobectomy versus pneumonectomy: tumor characteristics and comparative analysis of feasibility and results.

BACKGROUND: Sleeve lobectomy (SL) seems to have better results than pneumonectomy. Some authors propose to extend its indications. The aim of this study was to compare postoperative results, locoregional recurrence, and survival after sleeve lobectomy and pneumonectomy in focusing on right upper lobe cancer. METHODS: From 1984 to 2002, 973 lung resections were performed for T1, T2, and bronchial T3 right upper lobe non-small cell lung cancer. There were 756 lobectomies (L group), 151 pneumonectomies (RP group), and 66 sleeve lobectomies (SL group). The RP group was further divided with regard to intrapulmonary lymph node involvement. Pneumonectomy 1 (RP1) was a group of N0, intralobar N1, and skip metastasis involvement (N0-N2). Pneumonectomy 2 (RP2) was a group of extralobar N1 and nonskip metastasis involvement (N1-N2). Postoperative results were compared among SL, L, and RP groups. Survival was compared between the two homogeneous groups for oncologic characteristics (SL, RP1). RESULTS: Statistical comparison of 5-year actuarial survival showed a significant difference favoring SL (SL: 72.5%/ RP1: 53.2%; p = 0.0025). Postoperative mortality was higher after RP (L: 2.9% / SL: 4.5%/ RP: 12.6 %). Significant factors limiting SL were tumor size, extralobar N1, and main bronchus involvement (p = 0.000026, 0.0002, and 0.005, respectively). CONCLUSIONS: Immediate and long-term survival appears better after sleeve lobectomy than right pneumonectomy for comparable stages of right upper lobe cancer. For frequency to increase by systematic attempt at SL, limited by large tumors and extralobar N1 involvement, the only way should be after favorable response to induction chemotherapy.

Pneumonectomy for unilateral destroyed lung with pulmonary hypertension due to systemic blood flow through broncho-pulmonary shunts.

OBJECTIVE: Three decades ago, a few patients with pulmonary hypertension and respiratory failure associated with a unilateral destroyed lung were reported to have been treated by a pneumonectomy. In the present study, we investigated the clinical features, operative indications, and results of four cases with pulmonary hypertension that underwent a pneumonectomy for a unilateral destroyed lung. METHODS: Four patients (three males, one female) with a destroyed lung and pulmonary hypertension (mean pulmonary arterial pressure >25 mmHg) were treated by a pneumonectomy between 1999 and 2002 at our institution. Their mean age was 59 years old (range 42-68 years). The underlying lung disease, Medical Research Council (MRC) dyspnea scale, respiratory function, arterial blood gas analysis, pulmonary arterial pressure, preoperative management, operative procedure, and postoperative course for each were reviewed retrospectively. RESULTS: The underlying lung disease that caused the destroyed lung was bronchiectasis in two patients, chronic empyema with bronchopleural fistula in one, and necrotizing pneumonia in one. The average mean pulmonary artery pressure was 33 mmHg (range 25-42 mmHg), which decreased to 27 mmHg (range 19-36 mmHg) after occlusion of the pulmonary artery in the affected lung. Following the pneumonectomy, the average mean pulmonary artery pressure was decreased to 17 mmHg (range 11-25 mmHg). Chronic inflammatory symptoms and functional impairments (showed by blood gas analysis, pulmonary arterial pressure, or MRC dyspnea scale) improved post-pneumonectomy. There was no operative death, though postoperative cardiorespiratory failure occurred in one patient. All patients were discharged from the hospital. CONCLUSIONS: We concluded that a pneumonectomy procedure may be indicated for selected patients with a unilateral destroyed lung and pulmonary hypertension due to systemic blood flow though broncho-pulmonary shunts.

Comparison of surgical results after pneumonectomy and sleeve lobectomy for non-small cell lung cancer: trends over time and 20-year institutional experience.

OBJECTIVE: Sleeve lobectomy is a lung-saving procedure for central tumors for which the alternative is pneumonectomy. The purpose of this study was to report the clinical characteristics, operative results, survival, and late outcomes over 20 years in patients who underwent sleeve lobectomy and pneumonectomy at our institution. METHODS: There were 62 patients who underwent sleeve lobectomy (SL group) and 110 who underwent pneumonectomy (PN group). Comparisons of the demographics, morbidity, and survivals between the groups were performed by unpaired t-test, chi(2)-test, and log-rank test. RESULTS: Patients who underwent a pneumonectomy showed a significantly advanced pathological stage, and a larger tumor size than those who received a sleeve lobectomy, whereas there were no significant differences in histology, ratio of combined resection and induction therapy, or total morbidity. There were three in-hospital deaths (4.8%) in the SL group and four (3.6%) in the PN group. Local relapse and distant recurrence incidence were similar between the two groups. The 5-year-survival rates of the SL and PN groups were 54% and 33%, respectively (p<0.0001). However, there were no differences in 5-year survivals in patients with pathological stage I/II (SL, 59% vs PN, 63%) and those who received induction therapy (SL, 22% vs PN, 52%) between the groups. CONCLUSIONS: Both pneumonectomy and sleeve lobectomy were performed with an acceptable risk of operative mortality and satisfactory 5-year survival rate. The indication of pneumonectomy is aimed to perform a curative resection for locally advanced lung cancer, particularly after induction therapy that is otherwise unresectable, and the selected patients will likely benefit from a complete resection.

Morbidity and mortality after neoadjuvant therapy for lung cancer: the risks of right pneumonectomy.

BACKGROUND: The risks of complications in patients undergoing thoracotomy after neoadjuvant therapy for nonsmall cell lung cancer remain controversial. We reviewed our experience to define it further. METHODS: All patients undergoing thoracotomy after induction chemotherapy from 1993 through 1999 were reviewed. Univariate and multivariate methods for logistic regression model were used to identify predictors of adverse events. RESULTS: Induction chemotherapy included mitomycin, vinblastine, and cisplatin (179 patients), carboplatin and paclitaxel (152 patients), and other combinations (139 patients). Eighty-five patients (18%) received preoperative radiation. Operations were pneumonectomy (97 patients), lobectomy (297 patients), lesser resection (18 patients), and exploration only (58 patients). Total mortality was 7 of 297 (2.4%) and 11 of 97 (11.3%) for all lobectomies and pneumonectomies, respectively, but mortality was 11 of 46 (23.9%) for right pneumonectomy. Complications developed in 179 patients (38%). By multiple regression analysis, right pneumonectomy (p = 0.02), blood loss (p = 0.01), and forced expiratory volume in one second (percent predicted) (p = 0.01) predicted complications. No factor emerged to explain this high right pneumonectomy mortality rate. CONCLUSIONS: Pulmonary resection after neoadjuvant therapy is associated with acceptable overall morbidity and mortality. However, right pneumonectomy is associated with a significantly increased risk and should be performed only in selected patients.

Incidence of major pulmonary morbidity after pneumonectomy: association with timing of smoking cessation.

BACKGROUND: The prevention of major pulmonary events (MPEs) after pneumonectomy may minimize postoperative mortality rates. The purpose of this study was to identify preoperative and perioperative factors associated with the development of MPEs after pneumonectomy to help predict which patients are at increased risk for MPEs. METHODS: We retrospectively reviewed the medical records of all patients (n = 261) who underwent pneumonectomies between January 1990 and May 1999. We analyzed preoperative and perioperative risk factors, the primary end point of an MPE and the secondary end points of mortality (in-hospital or 30 days postprocedure), length of stay, and hospital charges. A postoperative MPE included only pneumonia or acute respiratory distress syndrome as defined by the Centers for Disease Control and the American and European Consensus Conference's established criteria. Simple atelectasis that did not progress to pneumonia or a documented aspiration was not included. RESULTS: Four patients died within 12 hours of operation; the records of the remaining 257 patients were analyzed. An MPE occurred in 33 (12.8%) of 257 patients; 16 (6.2%) of 257 patients died. A multivariate analysis performed on relevant variables showed that only the timing of smoking cessation (1 month or sooner before operation) was a significant predictor of an MPE. Age, side of pneumonectomy, and the use of preoperative chemotherapy or combined chemotherapy and radiation therapy were not significant predictors of an MPE. An MPE significantly increased the mortality rate 2.1% versus 39.3%, p < 0.001). CONCLUSIONS: Mortality after pneumonectomy increased significantly with the development of an MPE. Patients who continue to smoke within 1 month of operation are at an increased risk for developing an MPE. Interventions to minimize MPEs may minimize the mortality rate after pneumonectomy.

Completion pneumonectomy: factors affecting operative mortality and cardiopulmonary morbidity.

BACKGROUND: The purpose of this report is to analyze preoperative and perioperative factors affecting operative mortality and cardiopulmonary morbidity after a completion pneumonectomy. METHODS: We retrospectively reviewed all patients who underwent completion pneumonectomy from January 1985 through September 1998 at the Mayo Clinic in Rochester, MN. Factors affecting operative mortality and postoperative morbidity and were analyzed using univariate and multivariate analysis. RESULTS: There were 115 patients (73 men and 42 women), with a median age of 64 years (range, 12 to 83 years). Indication for pneumonectomy was benign disease in 57 patients (49.6%), lung cancer in 51 (44.3%) and metastatic disease in 7 (6.1%). There were 24 deaths (mortality 20.9%, 95% CI 13.9% to 29.4%). Mortality for patients undergoing completion pneumonectomy for benign disease, lung cancer, and metastatic cancer was 26.3%, 17.6%, and 0%, respectively (p = 0.24). Factors adversely affecting mortality with univariate analysis included advanced age (p = 0.004), preoperative corticosteriod use (p = 0.01), decreased preoperative diffusion capacity of lung to carbon monoxide (p = 0.01), intraoperative blood transfusion (p = 0.04), and excessive crystalloid infusion within the first 12 hours (p = 0.01) and 24 hours (0.03) postoperatively, respectively. Factors adversely affecting mortality with multivariate analysis included advanced age (p = 0.001), preoperative corticosteriod use (p = 0.002), and low preoperative hemoglobin (p = 0.02). Cardiopulmonary complications occurred in 72 patients (63.7%). Factors adversely affecting morbidity with univariate analysis included benign disease (p = 0.002), decreased preoperative diffusion capacity of lung to carbon monoxide (p = 0.04), bronchial stump reinforcement (p = 0.0001), and excessive crystalloid infusion within the first 12 hours (p = 0.006) and 24 hours (p = 0.02) postoperatively, respectively. Factors adversely affecting morbidity with multivariate analysis included advanced age (p = 0.005) and bronchial stump reinforcement (p = 0.001). CONCLUSIONS: Multiple factors adversely affect operative mortality and cardiopulmonary morbidity after completion pneumonectomy. Although completion pneumonectomy remains a high-risk procedure, especially for benign disease, it still should be considered a treatment option in selected patients.

Cardiovascular effects of positive end-expiratory pressure (PEEP) after pneumonectomy in dogs.

Little is known regarding the hemodynamic effect of positive end-expiratory pressure (PEEP) following pneumonectomy. To investigate this, 9 mongrel dogs underwent PEEP before and after lung resection. With the chest closed, the dog anesthetized, and partial pressure of carbon dioxide constant, PEEP was added in increments of 2 mm Hg until the animal's condition became hemodynamically unstable. At each level of PEEP, aortic, pulmonary, left atrial, and central venous pressures were monitored while aortic flow (cardiac output) was determined with an electromagnetic probe and airway pressure was measured with a Millar catheter in the respiratory tubing. Pneumonectomy was then performed, PEEP was again sequentially added, and the same measurements were recorded. Both before and after pneumonectomy, a strong positive linear correlation exists between the level of PEEP and pulmonary vascular resistance (PVR) (r greater than 0.74; p less than 0.05). Also, there is a high negative linear correlation between the level of PEEP and cardiac output (r greater than -0.76; p less than 0.05). At 0 mm Hg of PEEP, the PVR is higher after pneumonectomy than before (p less than 0.02). The incremental elevation in PVR persists after pneumonectomy at each level of PEEP, and in 5 of the 9 dogs the slope of the linear regression line relating PVR to PEEP was steeper following resection (p less than 0.05), thereby demonstrating an exaggerated effect of PEEP on PVR. In addition, all animals had a lower cardiac output at each comparable level of PEEP following pneumonectomy (p less than 0.05).(ABSTRACT TRUNCATED AT 250 WORDS)

Alterations in pulmonary function following pneumonectomy for bronchogenic carcinoma.

Twenty-one patients who underwent pneumonectomy for bronchogenic carcinoma at the Nashville Veterans Administration Hospital from November, 1977, to March, 1980, were evaluated with standard pulmonary function tests preoperatively and postoperatively. Twelve patients had Stage I disease, 4 patients had Stage II, and 5 patients had Stage III disease. The interval between the operative procedure and postoperative testing ranged from 2 to 33 months (mean, 12.4 months). Mean functional loss of pulmonary capacity after pneumonectomy was based on analysis of preoperative and postoperative forced vital capacity (FVC) and initial-second forced expiratory volume (FEV1) indices. The mean functional loss as expressed by FVC was 41.5% after right pneumonectomy and 34.0% after left pneumonectomy. The mean functional loss as expressed by FEV1 was 40.2% after right pneumonectomy and 38.3% after left pneumonectomy. The postoperative functional status of each patient was classified according to the New York Heart Association criteria. Nineteen of the 21 patients were in Class I or II preoperatively. Postoperatively, 10 patients were in Class I or II and 11 in Class III or IV. The results indicate that a postoperative FVC less than 2.5 liters and FEV1 less than 1.5 liters are not compatible with active life.

Survival and prognosis after pneumonectomy for lung cancer in the elderly.

BACKGROUND: The number of elderly patients with lung cancer is increasing. This study was undertaken to assess the validity of pneumonectomy for the treatment of lung cancer in this patient group. METHODS: Twenty-seven patients 70 years old or older (elderly group) and 95 patients younger than 70 years (younger group) who underwent pneumonectomy between January 1985 and March 1996 formed the study group. In the elderly group, 22 patients had squamous cell carcinoma, 2 had adenocarcinoma and 3, small cell carcinoma; 1 patient was in postoperative stage I, 4 patients were in stage II, 14 in stage IIIA, 5 in stage IIIB, and 3 in stage IV of the disease. The only significant differences in patient characteristics between the two groups were the percentage of patients undergoing right pneumonectomy and the percentage of patients receiving chemotherapy or radiotherapy within 3 months before or after operation or both times. RESULTS: The prognosis for the elderly group was comparable to that of the younger group for all stages of the disease; the overall 5-year survival rate was 30.5% for the younger group and 11.5% for the elderly group. However, operation-associated mortality was significantly higher in the elderly group (22.2% versus 3.2%; p < 0.005). The prognosis was better for patients with a centrally located tumor than a peripheral tumor in both groups [13.5% versus 2.0% in the elderly group and 46.7% versus 5.2% (p < 0.01) in the younger group] and significantly better for patients having a left pneumonectomy than a right pneumonectomy in the younger group (46.7% versus 5.2%; p < 0.01) but not in the elderly group (13.7% versus 22.2%). Adjuvant treatment did not have any beneficial effect on the prognosis in either group. CONCLUSIONS: Pneumonectomy for lung cancer in elderly patients appears to be justified because the outcome in our study was comparable with that for the younger patients. However, it should be performed only in carefully selected patients because of the increased operative risk.

Pneumonectomy for lung metastases: indications, risks, and outcome.

BACKGROUND: Resection of pulmonary metastases (PM) by pneumonectomy is infrequently performed and benefits are uncertain. METHODS: From 1985 to 1995, 42 patients underwent pneumonectomy for PM. Twenty-nine patients had PM from sarcomas, 12 patients from carcinomas, and 1 patient from melanoma. The indications for pneumonectomy were pulmonary recurrences in 12 patients, PM centrally located in 26 patients, and high number of PM in 4 patients. There were 11 intrapericardial and 6 extended pneumonectomies. The average number of PM resected was 3. Twenty-two patients (52%) had lymph nodes involvement. RESULTS: There were 2 postoperative deaths (4.8%) related to pneumonectomy and one death within 30 days for rapidly evolving disease; 4 patients (9.5%) had major postoperative complications that were medically treated. Five patients (12%) were operated on for recurrences on the residual lung. At the completion of the study, 12 patients were still alive, 8 without recurrences. The median survival was 6.5 months (range, 1 to 144 months); the 5-year survival was 16.8%. CONCLUSIONS: Pneumonectomy should not be considered an absolute contraindication in patients with PM, but the poor outcome of our series suggests strict criteria of selection.

Is there a role for pneumonectomy in pulmonary metastases? International Registry of Lung Metastases.

BACKGROUND: Although sublobar and lobar resections are accepted operations for pulmonary metastases, pneumonectomy is viewed as a major incursion on Stage IV patients. We considered it important to ascertain the current results of pneumonectomy for pulmonary metastases since little information is available. METHODS: Of the 5,206 patients with pulmonary metastasectomy reported by the International Registry of Lung Metastases, 133 (3%) underwent primary, and 38 (1%) completion pneumonectomy between 1962 and 1994. Data were analyzed to determine the operative mortality rates, survival rates, and determinants of survival. RESULTS: Primary pneumonectomy was performed for metastatic disease mainly from epithelial (49%, 65 of 133) and sarcomatous (33%, 43 of 133) tumors. Indications were central lesion, eg, proximal endobronchial or hilar nodal metastases. Operative mortality was 4% (4 of 112) and a 5-year survival rate of 20% was achieved following complete resection (R0) in 112 patients. In contrast, the 21 incompletely resected patients had an operative mortality rate of 19% (4 of 21), and the majority did not survive beyond 2 years (p = 0.02). Survival was determined by the completeness of resection and not histology of the primary tumor, number of metastases, nodal status, and disease-free interval. In the 38 completion pneumonectomy patients, 35 were operated for recurrent disease and 3 for residual disease. Sarcomatous secondaries predominated in 28 patients. Complete resection was achieved in 31 patients (82%). The operative mortality rate was 3% (1 of 38 patients) and the 5-year survival rate was 30%. CONCLUSIONS: Pneumonectomies for pulmonary metastases, albeit infrequently performed, were associated with acceptable operative mortality and long-term survival when performed in selected patients amenable to complete resection.

Early post-pneumonectomy complications in the elderly.

OBJECTIVE: The surgical treatment of non-small cell lung cancer (NSCLC) in elderly patients presents a serious challenge to thoracic surgeons. As there is considerable divergence of opinion about both the mortality and morbidity rates, it is important to set guidelines for proper patient selection. METHODS: Early post-operative complications in 42 patients aged over 70 years who had undergone pneumonectomy because of NSCLC (Group I) were analyzed. The control group (Group II) consisted of 48 patients, also aged over 70 years, but who had undergone lobectomy or wedge resections. In both groups, the pre-operative conditions and 30-day morbidity and mortality were evaluated. RESULTS: Postoperative complications occurred significantly more frequently in pneumonectomy patients (78.5%) than in Group II (58%). Transient or long-standing arrhythmias were noted in 20 patients (47.6%) from Group I and in 17 (35.4%) from Group II. Pulmonary complications occurred in 17 patients (40.4%) from Group I and 16 (33.3%) from Group II. The most important factors contributing to post-operative complications in pneumonectomy patients were performance status (WHO), chronic obstructive pulmonary disease (COPD) and elevated level of blood urea nitrogen (BUN). The highest impact on early mortality in pneumonectomy patients was exerted by COPD, arterial hypertension, formation of broncho-pleural fistula (BPF), the need for re-thoracotomy and high level of BUN. CONCLUSIONS: (1) Pneumonectomy in patients over the age of 70 carries a considerable risk of severe post-operative complications and death, when compared to patients with less extensive pulmonary resections. (2) Elderly patients with impaired Performance Status (WHO 2 or more) and co-existing arterial hypertension, COPD and elevated level of BUN should be considered for pneumonectomy very carefully and cautiously.

Long-term outcomes and risk factor analysis after pneumonectomy for active and sequela forms of pulmonary tuberculosis.

OBJECTIVE: The prevalence of pulmonary tuberculosis remains high in several areas of the world, and pneumonectomy is often necessary to treat the disease. We retrospectively analyzed the morbidities, mortalities, and long-term outcomes after pneumonectomy for the treatment of active tuberculosis or its sequelae. MATERIALS AND METHODS: Between 1981 and 2001, 94 patients underwent either pneumonectomy or pleuropneumonectomy for the treatment of tuberculosis. The patients included 44 males and 50 females and the mean age was 40 (16-68) years. The pathology included destroyed lung in 80, main bronchus stenosis in ten, and both lesions in four. Surgical procedures performed were pneumonectomy in 47, pleuropneumonectomy in 43, and completion pneumonectomy in four. RESULTS: One patient died postoperatively due to empyema. Twenty-three complications occurred in 20 patients: empyema in 15 (including seven bronchopleural fistulae), wound infections in five, and other complications in three. Univariate analysis revealed the presence of empyema, pleuropneumonectomy, prolonged operation time, old age, and intraoperative contamination as risk factors of postpneumonectomy empyema; it also showed that low preoperative FEV(1) and postoperative persistent positive sputum AFB were risk factors of bronchopleural fistula. In multivariate analysis, old age and low preoperative FEV(1) were risk factors of empyema while low preoperative FEV(1), positive sputum acid-fast bacilli, and the presence of aspergilloma were risk factors of bronchopleural fistula. There were 12 late deaths. Actuarial 5- and 10-year survival rates were 94+/-3% and 87+/-4%, respectively. CONCLUSION: Pneumonectomy could be performed with acceptable mortality and morbidity, and could achieve satisfactory long-term survival for the treatment of tuberculosis. In patients with risk factors, special care is recommended to prevent postoperative empyema or bronchopleural fistula.
