Thoracic surgery in the elderly--co-morbidity is the limit.

A retrospective chart review was performed in 242 consecutive patients aged 65 years or older who were treated in an academic surgical centre between January 2004 and July 2007. A total of 249 thoracic procedures were performed in 242 patients, of whom 143 were men and 99 women with a mean age of 69.9 years (range 65-92). Overall operative mortality was 2.4%, rising to 26.4% in emergency patients. Negative predictors for perioperative mortality were: American Society of Anesthesiology (ASA) class 4, pre-existing kidney failure, leucocytosis, low haemoglobin, elevated C-reactive protein, diabetes mellitus and emergency surgery. In addition, the risk of major and minor complications resulting in a prolonged hospital stay was increased in emergency patients, patients with multiple co-morbidities and ASA class 3 or 4. Appropriate thoracic surgery can be offered to the elderly with an acceptable level of perioperative morbidity and mortality. Regardless of age, a high degree of co-morbidity or emergency surgery are the main risk factors for perioperative mortality and/or prolonged hospital stay.
