Patients and methods
A prospective study was performed on patients operated on from May 1994 to August 1996. This protocol was approved by our institutional review board, and patients signed a separate informed consent form before entry into this study. Patients were eligible for entry if they had a predicted postoperative forced expiratory volume in 1 sec (FEV1) > 800 mL. This was calculated using the fraction of functional lung segments remaining after resection [7] or by radioisotope ventilation perfusion
Results
Forty patients who entered the study had a lung resection by open thoracotomy. There were 29 men and 11 women, with a mean age of 63.5 years (range 43 to 82 years). Thirty-five had non-small cell lung cancer, including 19 stage I, 3 stage II, 9 stage IIIA, 3 stage IIIB, and 1 stage IV, according to the American Joint Committee on Cancer staging system [17]. Five had pulmonary resection for other reasons. The operations performed were 29 lobectomies, 2 bilobectomies, and 9 segmental or wedge
Comment
Pulmonary complications in patients undergoing lung resection prolong hospital stay and cost, are associated with increased operative mortality, and predict long-term disability 9, 18. Hence, accurate prediction of which patients will develop pulmonary complications after lung resection may be helpful in determining in which patients the risk of surgery is acceptable. Spirometry has been used to predict the risk of complications after lung resection for more than four decades, and is still

2017, Journal of Surgical ResearchCitation Excerpt :However, it has been reported that the cardiovascular complications that develop after VATS are more likely to result in a fatal outcome than the complications that occur after open surgery.3 Considering that postoperative cardiopulmonary complications tend to continue for the full length of the patient's stay and require expensive medical resources,4 the accurate prediction of cardiopulmonary complications after VATS is mandatory in the counseling of patients who will undergo VATS for lung cancer. With respect to the preoperative functional measures, forced expiratory volume in 1 s (FEV1) is considered to be the most valuable parameter in screening for patients who are at risk of postoperative cardiopulmonary complications.5
