Diagnostic laparoscopy for intraabdominal evaluation and ventriculoperitoneal shunt placement in children: a means to avoid ventriculoatrial shunting.

BACKGROUND

Laparoscopic assistance for the placement of a ventriculoperitoneal shunt (VPS) has been shown to be a safe, effective, and minimally invasive approach for distal peritoneal shunt placement. The purpose of our study was to review our experience with laparoscopy for VPS placement in patients with a potential hostile abdomen.

MATERIALS AND METHODS

After institutional review board approval, a retrospective analysis of all patients who underwent diagnostic laparoscopy for VPS placement from March 2009 to March 2013 was performed. Patient demographics and outcomes were analyzed.

RESULTS

Twenty-seven patients underwent diagnostic laparoscopy for VPS placement at a mean age of 7.7 ± 6.8 years. Twenty-five patients had previous shunts placed in the peritoneum, whereas 2 underwent initial placement. Sixteen patients (59%) had undergone previous non-shunt abdominal operations. Twenty-three patients (85%) had successful peritoneal shunt placement. Distal peritoneal shunt placement was unsuccessful at the time of laparoscopy in 4 patients (15%) secondary to adhesions. Of the 23 patients who had successful peritoneal shunt placement, 57% did not require further shunt intervention, 22% underwent conversion to a ventriculoatrial shunt, 17% underwent re-externalization, and 4% required distal shunt revision. Of the 4 patients who required externalization, 3 underwent a second laparoscopic procedure with successful peritoneal shunt placement.

CONCLUSIONS

Diagnostic laparoscopy eliminated the need for ventriculoatrial shunt placement in 85% of patients with a potentially hostile abdomen. Sixty percent required no further shunt revision. Laparoscopic-assisted peritoneal shunt insertion is a safe, minimally invasive technique in children with the added benefit of allowing full exploration and adhesiolysis.
