BACKGROUND: Pneumonectomy remains a relatively high-risk procedure. However, the underlying mechanism is still unknown. Thus, the effort to find out predisposing factors for surgical risks continues. We investigated the effect of both water-load control and sampling lymphadenectomy technique on perioperative morbidity and mortality after pneumonectomy. MATERIAL AND METHODS: A hundred and three consecutive patients undergoing simple pneumonectomy were included in the prospective study. Pneumonectomy was performed for lung cancer in 92 patients and for benign diseases in 11 cases; 81 patients were male and 22 female, and the mean age was 53.4 +/- 11.4 years. Both sampling and completion lymphadenectomy techniques were used randomly. Water-load was carefully limited to values as low as possible, depending on stable hemodynamics during and after operation. RESULTS: There were no deaths, and none of the patients needed postoperative mechanical ventilation. Major complications included dyspnea in 9 patients and supraventricular arrhythmias in 13 patients. Completion lymphadenectomy increased morbidity in both right and left pneumonectomy. CONCLUSIONS: Both water-load limitation and sampling lymphadenectomy technique may decrease morbidity and mortality after pneumonectomy.
