Efficacy of Laparoscopy Guided Ventriculo-Peritoneal Shunt : Analysis of Data in 102 Consecutive Patients / 대한뇌혈관외과학회지

ABSTRACT

OBJECTIVE: This study compare outcomes in patients with laparoscopic guided ventriculo-peritoneal shunt placement with the nonlaparoscopic approach (conventional mini-laparotomy technique) in patients with hydrocephalus. METHODS: The study enrolled 102 adult patients who had undergone surgery between August 2005 and May 2008 for the treatment of hydrocephalus at our department. Seventy-six patients (38 men and 38 women) received laparoscopy-assisted distal catheter placement, and 26 patients (14 men and 12 women) received shunt surgery by a conventional mini-laparotomy approach. The median follow-up period of the non-laparoscopic group was 26 months (14-33 months) and laparoscopic group was 12 months (1-30 months). We analyzed age, sex, cause of hydrocephalus, type of shunt valve, operation time, shunt infection rate, and shunt distal catheter malfunction during follow-up. RESULTS: There was no statistically significant difference in age, sex, cause of hydrocephalus, or type of shunt valve. Shunt infections were observed in 10 cases (13.2%) in the laparoscopic group and in 4 cases (15.4%) in the mini-laparotomy group, which was not statistically significant. Distal shunt malfunction rates were significantly lower in the laparoscopic group (1.3%) compared to the mini-laparotomy group (11.5%, P<0.05). The mean operation time was also shorter in the laparoscopic group (108 min, 45-190 min) than of the mini-laparotomy group (146 min, 75-255 min, P<0.005). CONCLUSION: Laparoscopic guided placement of the VP shunt in hydrocephalus patients reduces shunt distal catheter malfunction and operation time.
