Laparoscopic placement of ventriculoperitoneal shunts: an innovative simplification of the existing techniques.
Ventriculoperitoneal shunting (VPS) remains one of the alternative choices for the surgical treatment of hydrocephalus. During the last two decades laparoscopy has been utilized to facilitate the placement of the abdominal portion of the shunt. We describe a minimally invasive laparoscopic technique, which facilitates the rapid, safe and direct placement of the peritoneal component of the VPS. A side frontal ventricular catheter is placed through a small burr hole and connected to the valve at the postauricular region. An infra-umbilical trocar is placed, using the Hasson technique, and after the pneumoperitoneum is established, a 10-mm laparoscope is introduced for identification of a VPS entry side free of adhesions. A 5-mm skin incision is made at the decided point of catheter insertion, usually at the right upper quadrant. Using a tunneler, the VPS catheter is placed subcutaneously from abdomen insertion point, to the postauricular region, where it is connected to the valve. A split type, 10-12 Fr and 12-15 cm long metallic puncture cannula, like those used for suprapelvic percutaneous bladder drainage, is introduced into the abdomen. Under direct laparoscopic vision the peritoneal portion of the VPS is passed into the abdomen through the cannula. The catheter is leaded to a desirable location by pointing the needle accordingly. Alteration of the position of the catheter can also be attained by entraining the catheter with the laparoscope and without using auxiliary graspers. The function of the VPS is confirmed under direct visualization. Suturing the abdominal and cranial incisions completes the procedure. We used this technique in a series of 12 patients with excellent outcome. There were no intra- or postoperative complications and no mortalities. Our technique is less invasive than a minilaparotomy, embraces all laparoscopic benefits and does not require auxiliary forceps or guidewires. It uses easy available materials with low cost, and attains an easy, rapid, and safe placement of the abdominal portion of the VPS.
