Background:
To determine any potential advantages of segmentectomy, we compared preoperative and postoperative lung function of patients who underwent segmentectomy with those in patients who underwent lobectomy.
Patients & Methods:
Between September 2001 and November 2003, preoperative and postoperative lung function, including DLco, was assessed in 43 patients with primary lung carcinoma. Of these 43 patients, 33 underwent single lobectomy (group L) and 10 underwent segmentectomy (group S). Both groups were examined for differences in lung volume through VC and FEV1.0 data, and all postoperative examinations were performed at 2 weeks after surgery. Changes in DLco (deltaDLco), VC (deltaVC) and FEV1.0 (deltaFEV1.0) were calculated and we compared the data for group L with those of group S.
Results:
Mean values for deltaVC, deltaFEV1.0 and deltaDLco in group L were 31.8 +/- 9.3, 29.6 +/- 10.9 and 27.2 +/- 14.0%, respectively, while these values in group S were 22.9 +/- 7.9, 20.1 +/- 9.6 and 13.9 +/- 11.6%, respectively. deltaVC, deltaFEV1.0 and deltaDLco were significantly smaller in group S than in group L (p < 0.01, p < 0.05 and p < 0.05, respectively).
Conclusion:
Segmentectomy was superior to lobectomy with regard to preservation of lung function in the early postoperative period.
