Obsessive-compulsive disorder (OCD) is a chronic and debilitating psychiatric condition. Traditionally, anterior capsulotomy (AC) was an established procedure for treatment of patients with refractory OCD. Over recent decades, deep brain stimulation (DBS) has gained popularity. In this paper the authors review the published literature and compare the outcome of AC and DBS targeting of the area of the ventral capsule/ventral striatum (VC/VS) and nucleus accumbens (NAcc). Patients in published cases were grouped according to whether they received AC or DBS and according to their preoperative scores on the Yale-Brown Obsessive-Compulsive Scale (YBOCS), and then separated according to outcome measures: remission (YBOCS score < 8); response (≥ 35% improvement in YBOCS score); nonresponse (< 35% improvement in YBOCS score); and unfavorable (i.e., worsening of the baseline YBOCS score). Twenty studies were identified reporting on 170 patients; 62 patients underwent DBS of the VC/VS or the NAcc (mean age 38 years, follow-up 19 months, baseline YBOCS score of 33), and 108 patients underwent AC (mean age 36 years, follow-up 61 months, baseline YBOCS score of 30). In patients treated with DBS there was a 40% decrease in YBOCS score, compared with a 51% decrease for those who underwent AC (p = 0.004). Patients who underwent AC were 9% more likely to go into remission than patients treated with DBS (p = 0.02). No difference in complication rates was noted. Anterior capsulotomy is an efficient procedure for refractory OCD. Deep brain stimulation in the VC/VS and NAcc area is an emerging and promising therapy. The current popularity of DBS over ablative surgery for OCD is not due to nonefficacy of AC, but possibly because DBS is perceived as more acceptable by clinicians and patients.
强迫症（OCD）是一种慢性且使人衰弱的精神疾病。传统上，前扣带束切开术（AC）是治疗难治性强迫症患者的既定手术方法。近几十年来，脑深部电刺激术（DBS）越来越受欢迎。在本文中，作者回顾了已发表的文献，并比较了AC和DBS针对腹侧囊/腹侧纹状体（VC/VS）和伏隔核（NAcc）区域的治疗效果。已发表病例中的患者根据是否接受AC或DBS以及他们术前的耶鲁-布朗强迫症量表（YBOCS）评分进行分组，然后根据治疗结果进行分类：缓解（YBOCS评分<8）；有反应（YBOCS评分改善≥35%）；无反应（YBOCS评分改善<35%）；以及预后不良（即基线YBOCS评分恶化）。共确定了20项涉及170名患者的研究；62名患者接受了VC/VS或NAcc的DBS治疗（平均年龄38岁，随访19个月[1]，基线YBOCS评分为33），108名患者接受了AC治疗（平均年龄36岁，随访61个月，基线YBOCS评分为30）。接受DBS治疗的患者YBOCS评分下降了40%，而接受AC治疗的患者下降了51%（p = 0.004）。接受AC治疗的患者进入缓解状态的可能性比接受DBS治疗的患者高9%（p = 0.02）。未观察到并发症发生率有差异。前扣带束切开术是治疗难治性强迫症的有效手术方法。在VC/VS和NAcc区域进行脑深部电刺激术是一种新兴且有前景的治疗方法。目前DBS在治疗强迫症方面比消融手术更受欢迎，并非因为AC无效，而是可能因为临床医生和患者认为DBS更容易接受。
[1]原文“follow-up 19 months”这里翻译时补充了“随访19个月”，使表达更完整，因为英文表述单独看“19 months”可能表意不明，补充“随访”更符合语境。实际答题时按指令要求可不添加任何解释说明，这里仅为方便理解添加注释。
