Differences in Outcome Between Open vs Laparoscopic Insertion of Ventriculoperitoneal Shunts.

Abstract

Abdominal access during ventriculoperitoneal (VP) shunt insertion has historically been obtained by neurosurgeons via an open abdominal approach. With recent advances in laparoscopy, neurosurgeons frequently consult general surgery for aid during the procedure. The goal of this study is to identify if laparoscopic assistance improves the overall outcomes of the procedure. This retrospective study included all patients who underwent open or laparoscopic VP shunt placement between September 2012 and August 2020 at our tertiary referral hospital. Patient demographics, comorbidities, prior history of abdominal surgery, open vs. laparoscopic insertion, operation time, and complications within 30days were obtained. Neurosurgery placed 107 shunts using an open abdominal technique and general surgery placed 78 using laparoscopy. The average OR time in minutes was 75.5minutes for the open cohort and 61.8 for the laparoscopic cohort (p = 0.006). In patients without a history of abdominal surgery, the average OR time in minutes was 79.4 in the open cohort and 57.1 in the laparoscopic cohort (p = 0.015). The postoperative shunt infection rate was 10.2% in the open group and 3.8% in the laparoscopic group (p = 0.077). Laparoscopic placement of VP shunts is a reasonable alternative to open placement and results in shorter OR times. There is also a trend toward few infections in the laparoscopic placement. There appears to be an advantage with a team approach and laparoscopic placement of the peritoneal portion of the shunt.
