A modified coaxial technique for biopsy and drainage procedures in the abdomen is described. This technique involves initial placement of a 23-gauge needle into an abdominal organ or mass. Once proper position is obtained, the hub of the needle is removed and a 19-gauge or larger needle is placed over the 23-gauge needle. Through this larger needle, either multiple biopsies are performed or guidewire exchange for a larger catheter is accomplished. The technique was used in performance of seven biopsy procedures, one biliary drainage procedure, and three nephrostomies.
描述了一种用于腹部活检和引流手术的改良同轴技术。该技术包括首先将一根23号针插入腹部器官或肿块。一旦获得合适的位置，将针座取下，然后在23号针上放置一根19号或更大号的针。通过这根更大号的针，可以进行多次活检或完成导丝交换以置入更大的导管。该技术用于实施7例活检手术、1例胆道引流手术和3例肾造瘘术。
