[Thoracoscopic and mini-open thoracotomic anterior correction for idiopathic thoracic scoliosis: a comparison of their clinical results].
OBJECTIVE
To compare the early clinical results of thoracoscopic and mini-open thoracotomic anterior correction for idiopathic thoracic scoliosis.


METHODS
Twenty-three cases with idiopathic right thoracic scoliosis were divided into 2 groups. Group A includes 8 females with average age of 14.8 years and average Cobb angle of 54 degrees . The Risser sign was +++ approximately ++++. These patients were operated on with thoracoscopic Eclipse instrumentation. Group B covers 2 males and 13 females with average age of 13.8 years and average Cobb angle of 57 degrees . The Risser sign was ++ approximately ++++. These patients were operated on with mini-open thoracotomic anterior instrumentation. The operative time, blood loss, postoperative drainage, instrumented levels, curve correction and early loss of correction of both groups were analyzed.


RESULTS
The patients of group A had average operative time of (360 +/- 72) min, (629 +/- 145) ml of intra-operative blood loss, (7.4 +/- 1.1) of instrumented levels, (500 +/- 150) ml of post operative drainage, 74 +/- 14% of curve correction rate and (8.6 +/- 2.7)% of early loss of correction after 6 approximately 18 m follow-up. The patients of group B had average operative time of (246 +/- 64) min, (300 +/- 110) ml of intra-operative blood loss, (7.8 +/- 0.9) of instrumented levels, (210 +/- 90) ml of post operative drainage, (70 +/- 12)% of curve correction rate and (4.6 +/- 1.9)% of early loss of correction. The curve correction rates of thoracoscopic and mini-open thoracoscopic anterior correction were not significantly different (P >0.05). But the operative time, blood loss, postoperative drainage, and early loss of correction showed significant difference (P <0.05).


CONCLUSIONS
Thoracoscopic and mini-open thoracotomic anterior correction for idiopathic thoracic scoliosis have their own indications. Both techniques are safe and effective to correct the idiopathic thoracic scoliosis with satisfied early results. But the early loss of correction of mini-open thoracotomic anterior correction is significantly less than that of thoracoscopic anterior correction.
