精神医学的問題が腰部脊柱管狭窄の手術成績に与える影響―前向き研究―BS-POPによる術前評価とJOABPEQとの関係

Prospective Cohort Study of the Impact of Psychiatric Problems on the Results of Surgical Treatment for Lumbar Spinal Stenosis : Relation Between Preoperative BS-POP Evaluation and Results of the JOABPEQ

　背景：腰部脊柱管狭窄の手術症例における精神医学的問題の存在が日本整形外科学会腰痛評価質問票(JOABPEQ)による手術成績に与える影響について明らかにする．

　対象と方法：腰痛を有する腰部脊柱管狭窄115例を術前の整形外科患者に対する精神医学的問題評価のための簡易質問票(BS-POP)から正常群と異常群に分類した．その2群間で手術前後の腰痛，JOABPEQ重症度スコア，手術有効率について比較検討した．

　結果：術前でのBS-POPで異常と判定される患者では，術後でのJOABPEQ重症度スコアと手術有効率が低い．

　結論：精神医学的問題は，腰部脊柱管狭窄のJOABPEQによる手術成績に影響する．

　Background：We evaluated the impact of psychiatric problems on the results of surgical treatment for lumbar spinal stenosis as evaluated by a postoperative JOABPEQ.

　Methods：We classified 115 lumbar spinal stenosis patients with low back pain into a normal group and a psychiatric problem group based on BS-POP findings.　The two groups were compared in regard to low back pain, JOABPEQ severity scores, and surgical treatment effectiveness.

　Results：The postoperative JOABPEQ severity score and surgical treatment effectiveness were lower in the group with psychiatric problems according to the preoperative BS-POP findings.

　Conclusions：Psychiatric problems have a negative impact on the results of surgery for lumbar spinal stenosis based on the JOABPEQ severity scores.
