摘要
目的 探讨超声在胰腺癌12 5I放射性粒子植入术中的作用。方法 术前根据肿块大小计算放射总剂量及粒子数量。术中超声实时监视 ,均匀布针并植入粒子。术后超声及 (或 )X线确认植入部位及有无漏植。结果 13例患者手术均获成功。术中超声清晰显示肿块 ,准确引导植入针的插入 ,成功监视粒子的植入 ,术后证实植入部位准确。结论 超声在该项技术中具有定位精确、实时监视、复查随访等作用 ,其应用前景广阔。
Objective To evaluate the usefulness of ultrasound during the operation of 125 I permanent brachytherapy for pancreas carcinoma.Methods According to the mass size,the total radiation dosage and the amount of radioactive seeds were calculated before operation.Then all needles were inserted evenly in the mass and radioactive seeds were implanted through the needles under ultrasonic guidance during the operation. At the end of operation,ultrasonography and/or abdominal radiography were applied to examine the distribution of seeds and to find if any place was left out. Results Thirteen patients were operated on successfully and the mass was displayed clearly with ultrasonography. Under the guidance of ultrasound,needles were exactly inserted in the mass and the whole process of implantment was easily observed. Locations were proved exactly by ultrasonography and abdominal radiography after operation. Conclusions Ultrasound has some important values in this procedure,such as precise orientation,real-time monitoring,follow-up evaluation,etc. Application of ultrasonography has the broad prospect in this field.
