Use of a new type of trocar for the surgical treatment of hydrocephalus: a simple and effective technique.

This study compared the use of a new type of peritoneocentesis trocar with conventional laparotomy for the placement of the distal catheter in the treatment of hydrocephalus with ventriculoperitoneal shunt. A total of 376 patients with hydrocephalus were recruited to the study and were assigned randomly to undergo insertion of the distal catheter by conventional laparotomy (n = 195) or using the new peritoneal trocar (n = 181). The time taken for the surgical procedure and the complication rate over the following 1-year period were compared between the two groups. The mean length of the procedure to place the distal catheter was significantly shorter in the trocar group compared with the laparotomy group. Infection and obstruction rates were significantly higher in the laparotomy group than in the trocar group. In conclusion, the use of the new trocar was associated with lower rates of surgically induced trauma and complications compared with conventional laparotomy.
