Percutaneous extraction of two deeply lodged foreign bodies

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.

Percutaneous removal of a biliary stent after acute spontaneous duodenal perforation

A 38-year-old woman was treated for malignant stricture by the endoscopic placement of a biliary endoprosthesis. She developed a large retroperitoneal biloma secondary to acute duodenal perforation by the stent. We describe the successful percutaneous retrieval of the biliary stent through a retroperitoneal approach which also permitted drainage of the biloma.

Percutaneous retrieval of a surgical laparotomy sponge from the peritoneal cavity

Percutaneous retrieval of an extravascular foreign body is an uncommon procedure. This report describes the successful retrieval of a 46 x 46-cm laparotomy sponge from the peritoneal cavity using a Nitinol Gooseneck Snare system. This technique can eliminate the need for exploratory surgery and may be particularly useful in poor operative candidates.
