159 Outcomes of Ventriculoperitoneal Shunt Placement with or without Laparoscopic Assistance: An Analysis of the National Inpatient Sample

Abstract

INTRODUCTION:Ventriculoperitoneal shunt (VPS) can be placed solely by a neurosurgeon often via an open-laparotomy approach, or laparoscopically as a collaborative effort between a neurosurgeon and a general surgeon. Prior studies have shown conflicting results when examining outcomes regarding infection, revision rate, hospital charges, length of stay, and mortality between the open mini-laparotomy and the laparoscopic approaches.METHODS:We performed a retrospective database study of the NIS from October 2015-December 2017 utilizing International Classification of Diseases, 10th Revision coding to identify all cases of VPS placement. All analyses accounted for the sampling design of the NIS.RESULTS:A total of 6,580 cases (4,969 with open mini-laparotomy approach and 1,611 with laparoscopic collaborative approach) met inclusion criteria. Hospital charges (median $91, 900 v. $84,400; p = 0.231) and revision rate (3.2% v. 3.1%; p = 0.796) were similar between approaches. There were no significant differences in length of stay, mortality, or complication rates between the two approaches.CONCLUSION:The collaborative, laparoscopic approach to VPS placement has similar outcomes and is non-inferior to the traditional open mini-laparotomy approach.
