Abstract
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.
