Laparoscopic ventriculoperitoneal shunts: benefits to resident training and patient safety.

BACKGROUND AND

OBJECTIVES

Symptomatic hydrocephalus is a surprisingly common clinical condition. Neurosurgeons are expert at ventriculostomy, but minimally invasive peritoneal access is outside the realm of their current training. We have adopted a multidisciplinary approach, with general surgeons positioning the distal shunt. Our objective was to review this recent experience.

METHODS

All distal shunts were placed by a single surgeon with resident assistance. After ventriculostomy, the shunt tubing was tunneled onto the anterior abdominal wall. A Veress needle was placed through the tunnel incision and the abdomen insufflated. A 5-mm optical access trocar and camera were introduced via a separate stab incision. The shunt tubing was then directed into the abdominal cavity using a Hickman introducer kit, with flow confirmed visually.

RESULTS

Study patients who had between 0 and 10 previous abdominal operations received 111 consecutive shunts. There was one intraoperative complication, a colon injury during trocar placement. In this case, the colotomy was repaired and the shunt placed in the pleural space. There were no conversions to the open abdominal approach. Postoperatively, there were no wound infections, no cases of shunt malpositioning, and there were no deaths.

CONCLUSIONS

Laparoscopic placement of ventriculoperitoneal shunts is feasible, safe, and carries a low rate of complications. The value to resident education in the practice of this procedure has not been previously emphasized. In the era of increased awareness of patient safety, laparoscopic VP shunting serves as a model for accomplishing both goals of improved outcomes and quality surgical education.
