This paper details the long-term results in patients treated with dorsal root entry zone (DREZ) lesions for the treatment of pain following brachial plexus avulsion, spinal cord injury, and herpes zoster. With our current operative technique, 82% of patients with brachial plexus avulsion injuries were afforded long-term pain relief. Patients with pain confined to dermatomes just below the level of spinal injury also did well with DREZ lesions, although the results were less good in patients with diffuse pain or with sacral pain. The postoperative results in patients with postherpetic pain were disappointing.
本文详细介绍了采用背根入髓区（DREZ）毁损术治疗臂丛神经撕脱伤、脊髓损伤及带状疱疹后疼痛患者的长期疗效。采用我们目前的手术技术，82%的臂丛神经撕脱伤患者获得了长期疼痛缓解。疼痛局限于脊髓损伤平面以下皮节的患者，DREZ毁损术效果也较好，不过弥漫性疼痛或骶部疼痛患者的效果较差。带状疱疹后疼痛患者的术后效果令人失望。
