Obsessive-compulsive disorder (OCD) is a common disease that has negative effects on functionality, and 10% of the patients do not respond to first-line treatments. Gamma-knife radiosurgery (GKRS) has been used in patients with treatment-resistant OCD, but the data on long-term outcomes are still unsatisfactory.
In this study, 12 patients who underwent GKRS between 2005 and 2020 were evaluated retrospectively. Anterior capsulotomy was performed using two 4-mm isocenters at the midputaminal point of the anterior limb of the internal capsule on each side with a maximum radiation dose of 140-180 Gy. Patients were followed up with the Yale-Brown Obsession and Compulsion Scale (Y-BOCS), Montgomery-Asberg Depression Rating Scale (MADRS), and Brief Psychiatric Rating Scale (BPRS) on the first, third, and sixth months.
After the procedure, a 35% reduction was observed in the overall Y-BOCS scores, and full response rate was 50%. There was a 49.5% decrease in the MADRS scores and a 57.8% decrease in the BPRS.
GKRS is an effective and non-invasive procedure with favorable side effects in treatment-resistant OCD with selected patients.
强迫症（OCD）是一种对功能有负面影响的常见疾病，10%的患者对一线治疗无反应。伽玛刀放射外科手术（GKRS）已用于治疗难治性强迫症患者，但长期疗效数据仍不令人满意。
本研究回顾性评估了2005年至2020年间接受GKRS治疗的12例患者。在内囊前肢的中豆状核点两侧使用两个4毫米等中心进行前囊切开术，最大辐射剂量为140-180 Gy。在第1、3和6个月使用耶鲁-布朗强迫症量表（Y-BOCS）、蒙哥马利-阿斯伯格抑郁量表（MADRS）和简明精神病评定量表（BPRS）对患者进行随访。
术后，Y-BOCS总分下降了35%，完全缓解率为50%。MADRS评分下降了49.5%，BPRS评分下降了57.8%。
对于部分难治性强迫症患者，GKRS是一种有效且无创的治疗方法，副作用较小。
