RESULTS
Estimation of the SF-36 scores showed that (1) all of the domain values were considerably lower in the preoperative patient group than in the second one (P<0.01); (2) the bodily pain scores were closely correlated to the social function scores (R=0.7, P<0.01), whereas the physical function was less related to the bodily pain (R=0.6, P<0.01). The weakest correlation was observed between bodily pain and mental health and general health (R=0.4, P<0.01).
