Abstract:
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.
