摘　　要：目的探讨高强度聚焦超声（high intensity focused ultrasound，HIFU）消融治疗胰腺癌的疗效和安全性。方法采用JC型高强度聚焦超声治疗系统，消融治疗44例胰腺癌患者。观察治疗前后的影像学变化及临床症状，评价HIFU治疗的疼痛缓解程度、生存期及不良反应。结果44例患者经HIFU治疗后，疼痛缓解率为94．74％，1、3、5年生存率分别为15．91％、6．82％、2．27％，中位生存时间为8个月（3～71个月）。无上消化道出血或胃肠穿孔等严重并发症。增强CT或MRI显示HIFU治疗区内组织消融。结论HIFU是一种治疗胰腺癌的有效方法。该法无创、安全性较高、止痛效果明显，适合病情较重、不能耐受其他方法治疗的患者。Objective To explore the efficacy and safety of high intensity focused ultrasound （HIFU） on pancreatic carcinoma. Methods Forty-four patients with pancreatic carcinoma were treated with HIFU. The response rate, clinical beneficial response, overall survival and side effects were evaluated after the treatment. Results The rate of pain relief was 94. 740/00, the overall 1-, 3-, and 5-years survival rates were 15.91%, 6.82%, 2.27%, respectively; and the median survival time was 8 （3 - 71） months. No complications, such as pancreatisis and gastrointestinal injury occurred. Conchlsion HIFU is an effective, non invasive and safe approach in the treatment of pancreatic carcinoma. For the patients with severe condition and intolerable to other methods, HIFU may be a good choice.
