We summarized the medical costs and cost-effectiveness of three surgical methods for ASD in patients with different backgrounds over 2 years postoperatively. The highest medical expense for the initial surgery was noted in the LLIF group. The cumulative improvement in QALY over the 2 years was higher in the LLIF group, although the difference was not significant, and the lowest overall cost-effectiveness was noted in the LLIF group.
