Laparoscopic retrieval of disconnected ventriculoperitoneal shunt catheters: report of two cases.

Two patients previously treated with ventriculoperitoneal shunt for hydrocephalus had the distal catheters disconnected, and they migrated to the free peritoneal cavity. The signs and symptoms of increased intracranial pressure occurred as a result of mechanical failure of the shunt system. Both patients successfully underwent a laparoscopic retrieval of the catheters using endoscopic grasping forceps, and revision of the ventriculoperitoneal shunt by inserting the new catheters into the peritoneal cavity was performed through a small entrance for the laparoscope. Recently, conventional laparotomy has been often replaced by laparoscopic surgery, and general surgeons are well familiar with the laparoscopic procedures. The significant advantage of this procedure is the ability to explore the entire peritoneal cavity for both diagnosis and treatment, and it is by far a less invasive approach than conventional laparotomy. The present report describes the laparoscopic procedure for removal of the migrated catheters and discusses its advantages over conventional laparotomy.
