ObjectiveLaparoscopic ventriculoperitoneal shunt surgery has been reported to have several advantages in selected patients. However, the prognostic factors have been understudied specifically for this surgery. We sought to investigate the factors influencing the complications after the laparoscopic ventriculoperitoneal shunt placement.MethodsAll surgeries in this prospective study were performed by the same team of neurosurgeons and general surgeons. Clinical parameters as well as potential risk factors for postoperative complications were analyzed. The endpoint was overall complications requiring surgical revision within the follow-up period after surgery.ResultsNinety-nine patients (51 male and 48 female) scheduled for laparoscopic-assisted ventriculoperitoneal shunt surgery between 2019 and 2021 were included. Overall shunt complication rate was 9% (9 of 99 cases), and there was 1 patient (1%) who had distal dysfunction among them. Body mass index ≥27 kg/m2 (hazard ratio 4.87; 95% confidence interval 1.05-22.57; P = 0.043), and nonprogrammable shunts (hazard ratio 7.91; 95% confidence interval 1.51-41.50; P = 0.014) were significantly associated with an increased risk of complications. Among 75 patients who received programmable shunts, the vertical distance from the distal tip to the presumed bottom of peritoneal cavity was significant positively associated with the number of pressure adjustments (R2 0.511, adjusted R2 0.504, and P < 0.001).ConclusionsVentriculoperitoneal shunt surgery provided benefits with little complication rate, whereas patients treated with nonprogrammable shunts and obese patients had less favorable outcome. A positive correlation between the vertical distance from the distal tip to the bottom of peritoneal cavity and pressure adjustments inferred to the advantage of the laparoscopic method.Copyright © 2022 Elsevier Inc.
