Comparison of incidence of shunt system failure between neuroendoscope-laparoscope assisted and non-endoscope-assisted ventricular-peritoneal shunt for hydrocephalus / 中华神经医学杂志

ABSTRACT

Objective To compare the incidence of shunt system failure between neuroendoscope-laparoscope assisted and non-endoscope-assisted ventricular-peritoneal shunt (VPS) for hydrocephalus.Methods A retrospective analysis was performed in the incidence of shunt system failure of 141 hydrocephalus patients accepted neuroendoscope-laparoscope assisted VPS,admitted to our hospital from January 2007 to August 2012,and 167 hydrocephalus patients with non-endoscope assisted VPS,admitted to our hospital from January 2001 to December 2006.All these patients were followed up for 1 to 72 months and the incidence rate of shunt system failure was compared between the two groups.Results Five patients failed in follow-up in patients accepted neuroendoscope-laparoscope assisted VPS; the incidence rate of shunt system failure in neuroendoscope-laparoscope assisted VPS was 5.1％,including 3 in ventricular end blockage and 4 in intraperitoneal end blockage; shunt valve was not noted.Twelve patients failed in follow-up in patients accepted neuroendoscope-laparoscope assisted VPS; the incidence rate of shunt system failure in neuroendoscope-laparoscope assisted VPS was 30.3％,including 31 in ventricular end blockage and 15 in intraperitoneal end blockage; shunt valve was noted in one patient.The incidence rate of shunt system failure in neuroendoscope-laparoscope assisted VPS was significantly lower than that in non-endoscope assisted group (x2=30.379,P=0.000).Conclusion In contrast to the non-endoscope assisted VPS surgery,the incidence of shunt system failure has been reduced significantly by neuroendoscope plus laparoscope assisted VPS surgery.
