In spite of the development of endoscopic surgery in hydrocephalus, ventriculoperitoneal shunt remains indicated in many cases particularly for non obstructive hydrocephalus. The peritoneal cavity is always an excellent receptacle for the LCS at the price of an unaesthetic abdominal scar, which may pose a problem, especially for the young adult. The trans-umbilical approach allows us to avoid the unsightly scar. Thus, between May 2004 and September 2006, a ventriculoperitoneal shunt was fashioned in 14 patients using a trans-umbilical access. Average age was 52 years and average post-intervention follow-up was 17 months. No patient developed infection, in particular in the umbilical area. One patient had to undergo a second operation for ventricular repositioning using the same peritoneal drain that could be repositioned via the trans-umbilical access with no particular problem. In one particular case, a full change of the shunt was necessary because of a sore on the shunt chamber, the material was reinstalled via the conventional umbilical access without any particular difficulty. This is the first preliminary study which confirms the feasibility of the trans-umbilical method for adults with no increase in the infectious risk, and with a very satisfactory aesthetic result in children.
