Percutaneous fluoroscopically guided removal of a deep retroperitoneal foreign body with a laparoscopic trocar and grasping device.

Traditionally, soft tissue foreign body removal is performed surgically. Superficial foreign body removal under ultrasonographic and fluoroscopic guidance has been reported. Herein, the authors report a case of percutaneous removal of a retroperitoneal foreign body under fluoroscopic guidance by using a modified laparoscopic trocar device and a laparoscopic grasping device. Iodinated contrast medium administered via the trocar device allowed visualization of the foreign body and distended the retroperitoneal space to allow for manipulation of the foreign body. The procedure was completed in a relatively short time and the patient made an excellent rapid postoperative recovery.
