CT引导下腹腔神经丛阻滞术治疗上腹部癌痛的临床应用研究

目的研究腹腔神经丛阻滞术治疗腹部顽固性癌痛的方法及疗效。方法30例各类上腹部恶性肿瘤患者，均有顽固性上腹疼痛，在CT引导下进行膈脚前及腹膜后肿大淋巴结内乙醇阻滞治疗。结果手术成功率100％，CT显示乙醇在腹主动脉周围及淋巴结内弥散良好，术后即刻至2周，总有效率达100％，随访至半年总有效率71．4％。结论CT引导下腹腔神经丛阻滞术，定位准确，疼痛缓解率高，并发症少，值得临床推广应用。

A study of the clinical application of neurolytic celiac plexus block using CT guidance to control the upper abdominal pain caused by cancer

Objective To study the methods and therapeutic effect of neurolytic celiac plexus block in treatment of intractable upper abdominal pain caused by cancer.Methods All the 30 patients with carcinoma of upper abdominal organs suffered from intractable upper abdominal pain.Ethanol was injected through neurolytic celiac plexus block under CT guidance with needle tip positioned into the tumorous retroperitoneal lymph nodes.Results The success rate was 100%.CT results showed ethanol diffused well in lymph nodes and surrounding aorta.The total effective rate of pain relief was 100% in two weeks and 71.4% in 6 months.Conclusion Neurolytic celiac plexus block using CT guidance is worth widely applying to clinics for its accurately choosing position,a high rate of pain relief and few complications.
