Fifty-six patients with intractable pain following a spinal cord injury were treated with dorsal root entry zone (DREZ) lesions. After a follow-up period ranging from 6 months to 6 years, 50% of patients had good pain relief. Certain pain syndromes tended to respond better to DREZ lesions than did others. Patients with pain extending caudally from the level of the injury and patients with unilateral pain were most likely to obtain pain relief from the procedure; diffuse pain and predominant sacral pain did not respond as well.
56例脊髓损伤后顽固性疼痛患者接受了背根入髓区（DREZ）毁损术治疗。随访时间为6个月至6年，50%的患者疼痛得到有效缓解。某些疼痛综合征对DREZ毁损术的反应比其他综合征更好。疼痛从损伤平面向尾端蔓延的患者以及单侧疼痛患者最有可能通过该手术缓解疼痛；弥漫性疼痛和主要的骶部疼痛反应则欠佳。
