Introdução: O transtorno obsessivo-compulsivo (TOC) é caracterizado por pensamentos intrusivos de etiologia não esclarecida, que pode ser graduada através do escore Y-BOCS. Diante da refratariedade a medicamentos, modalidades de neurocirurgia funcional têm surgido como alternativa ao tratamento dessa condição, como o Deep Brain Stimulation (DBS). Objetivo: Analisar os benefícios do uso do DBS em pacientes com TOC e compará-los com neurocirurgias ablativas Métodos: Trata-se de uma revisão integrativa com busca na base de dados PubMed utilizando os descritores “Deep Brain Stimulation”, “Obsessive compulsive disorder”, “Case report”, “Psychosurgery”, “Stereotactic” junto ao operador booleano “AND”. Posteriormente, realizou-se análise estatística dos relatos de caso (t de Student), a fim de avaliar alterações estatisticamente significativas nos pacientes. Resultados: DBS com estimulação no núcleo accumbens foi o procedimento mais realizado, enquanto nas cirurgias ablativas, a capsulotomia prevaleceu. Ademais, tanto os pacientes submetidos a DBS (p<0.001) como cirurgia ablativa (p=0.012) apresentaram uma redução estatisticamente significativa na pontuação Y-BOCS, embora sem variação significativa quando comparados entre si. Conclusão: Diante do estudo, o DBS mostrou-se uma alternativa importante para tratar pacientes com TOC refratário, embora apresente seus riscos que merecem ser considerados antes de sua aplicação.

Introduction: Obsessive-compulsive disorder (OCD) is characterized by intrusive thoughts of unknown etiology, which can be graded using the Y-BOCS score. Before the drug refractoriness, functional neurosurgery modalities have emerged as an alternative to treat this condition, such as Deep Brain Stimulation (DBS). Objective: To analyze the benefits of using DBS in patients with OCD and compare them with ablative neurosurgeries. Methods: This is an integrative review with research in PubMed database using the descriptors “Deep Brain Stimulation”, “Obsessive compulsive disorder”, “Case report”, “Psychosurgery”, “Stereotactic” together with the Boolean operator “AND”. Subsequently, a statistical analysis of the case reports (Student’s t) was carried out in order to assess statistically significant changes in the patients. Results: DBS with nucleus accumbens stimulation was the most common procedure, meanwhile in ablative surgeries, capsulotomy prevailed. In addition, both patients undergoing DBS (p<0.001) and ablative surgery (p=0.012) showed a statistically significant reduction in the Y-score BOCS, although without significant variation when compared to each other. Conclusion: In view of the study, DBS proved to be an important alternative to treat patients with refractory OCD, although it presents its risks that deserve to be considered before its application.
