Risk factors for early mortality and morbidity after pneumonectomy: a reappraisal.

BACKGROUND Pneumonectomy remains a high-risk procedure. Comprehensive patient selection should be based on analysis of proven risk factors. METHODS The records of 323 pneumonectomy patients were retrospectively reviewed. Multiple demographic data were collected. End points were operative mortality at 30 and at 90 days, major procedurally related complications, and cardiovascular events. Univariate and multivariate statistical analyses were performed. RESULTS Smoking habits, chronic obstructive pulmonary disease (COPD) status, induction chemotherapy status, diabetes, and obesity had no statistical influence on short-term outcomes. After right pneumonectomy, 30-day mortality (p = 0.045) and the incidence of bronchopleural fistulas (p = 0.009) were increased. Multivariate analysis for postoperative bronchopleural fistulas discovered that right pneumonectomies are the sole risk factor (p = 0.015). Univariate analysis for postoperative atrial fibrillation showed that male gender, age 70 and older, hypertension, and dyslipidemia are risk factors. Multivariate analysis found no definite risk factor. Patients with coronary artery disease had more postoperative cardiovascular events (p = 0.003). Among patients free of coronary artery disease, COPD led to an increased 90-day mortality rate (p = 0.028). CONCLUSIONS Patients with right pneumonectomies are at increased risk. Postoperative cardiovascular events are more frequent in coronary artery disease patients. COPD is a risk factor in patients free of coronary disease.

Surgery for aspergilloma: time trend towards improved results?

Surgery of aspergilloma has been renowned to be technically challenging and has a high complication rate. We have already demonstrated an improved outcome as a result of a reduction in complex cases related to history of tuberculosis. In this paper we will evaluate whether this time trend has continued during recent years. Initial presentation and postoperative outcome of 33 patients who underwent surgical treatment between 1998 and 2009 were reviewed and compared with two previous reports (group 1: 55 patients from 1974 to 1991; group 2: 12 patients from 1992 to 1997). Underlying disease was tuberculosis in 15% of patients (57% in group 1, 17% in group 2), and 12% of patients had complex aspergillomas (80% in group 1, 41% in group 2). Postoperatively, there was no mortality (5% in group 1, 0% in group 2). Morbidity decreased progressively in terms of bleeding (44% in group 1, 9% in group 2, and 6% in recently, accrued patients), of pleural space problems (47%, 18% and 12%, respectively), and of prolonged hospital stay (32%, 8% and 6%, respectively). With a decreased postoperative complications rate after resection, contemporary surgery of aspergilloma is safe and offers satisfactory early and long-term results.

Persistent N2 Disease After Induction Therapy Does Not Jeopardize Early and Medium Term Outcomes of Pneumonectomy

BACKGROUND Operative management of patients with persistent N2 disease after induction therapy is still debated. METHODS One hundred fifty-three consecutive patients underwent pneumonectomy from January 1999 until July 2005; 28 patients (18.3%) had persistent N2 disease after induction therapy (group 1), 32 patients (20.9%) had pathologic stage N0 or N1 after induction therapy (group 2), and 93 patients (60.8%) with pathologic N2 disease underwent immediate surgery (group 3). Short-term end points were operative mortality at 30 and 90 days and major complications. Long-term end points were 5-year survival and disease-free survival rates. RESULTS Demographics of the three groups were similar (age, sex, side of operation, type of chemotherapy, smoking status, and comorbidity such as coronary artery disease, diabetes, and chronic obstructive pulmonary disease). Thirty-day postoperative mortality was 10.7% in group 1, 3.1% in group 2 (p = 0.257), and 4.3% in group 3 (p = 0.201); 90-day postoperative mortality was 10.7% in group 1, 12.5% in group 2 (p = 0.577), and 9.7% in group 3 (p = 0.558). Incidence of major postoperative complications was similar. Five-year survival rate was 32.2% (median, 28 months; 95% confidence interval, 7 to 43) in group 1, 34.8% (median, 27 months; 95% confidence interval, 7 to 47) in group 2 (p = 0.685), and 12.4% (median, 15 months; 95% confidence interval, 11 to 19) in group 3 (p = 0.127). No statistical difference was found in terms of 5-year event-free survival, or regarding the side of pneumonectomy. CONCLUSIONS Our results suggest that pneumonectomy is justified in patients with persistent N2 disease after induction chemotherapy.
