[What influences reconvalescence after lung resection?].
BACKGROUND
Reconvalescence after lung resections underlies several influences. The aim of this study was to outline the effect of patient and operative factors.


METHODS
Between 1/97 and 6/98 a cross sectional prospective study was undertaken at the University of Ulm. 125 patients with lung resections for various reasons via anterolateral thoracotomy were included. Variants thought to affect postoperative recovery were statistically analysed using uni- and multivariate analysis. A "good postoperative recovery" (GPR) was seen as at least two of the following criteria were fulfilled on the second postoperative day: Spitzer Index >/=6, FEV1 >40% of preoperative measurement, pain on LASA scale </=3.


RESULTS
Chi-Square testing revealed a more frequent GPR for patients with benign diseases (61 vs 40%, p=0,0436), an atypical compared to anatomical resection (63 vs 40%, p=0,0157) and an opening of the retractor of not more than 13 cm (61 vs 34%, p=0,0033). Multivariate analysis demonstrated only the opening of the retractor as being of independent influence (p=0,0148). Age, sex, BMI, incision length, transsection of M. latissimus dorsi, number of accidental rib fractures, time of operation and routine of the surgeon were of no statistical relevance to GPR.


CONCLUSIONS
Malignant disease requiring anatomical lung resection is accompanied by delayed postoperative recovery when compared to lung resections for other reason. In contrast the width of opening of the retractor is of independent negative influence for reconvalescence. Once more the significance of a non-aggressive access procedure for lung resections is underlined.
