Interventional treatment of cystic diseases with d
The department of ultrasound therapy, Harbin Medical University, adopted the non-surgical dual needling minimally invasive technique for the treatment of hepatic, renal and pancreatic cystic diseases in more than 50 cases since May 2001 and the treatment was completed in one setting.
Associate Professor Zhou Xianli of the department of ultrasound of that hospital said that in the past a single needle was usually used for guidance of intervention therapy for benign space occupying cystic lesions of the solid organs. However, because of the displacement of the cystic lesion after shrinkage following aspiration, the aspiration needle might be displaced out of the cystic lesions or the needle tip might stick onto the cystic wall. This may result in inadequate evacuation of the cystic content and difficulties for introduction of the sclerosing agents, negatively influencing the treatment results as well as the increased chance of having complications. After investigating for a long time, they finally used the double needle aspiration instead of using the single needle, i.e., a soft tubular needle together with a metallic needle were inserted simultaneously into the cystic lesion. The soft tubular needle was used for drug injection and also for reserved use, and thus avoided the shortcomings of using a single needle aspiration technique giving higher rates of success and cure. The improved method was simple and easy for widespread application., http://www.100md.com
