    BackgroundNeurological injury requiring ventriculoperitoneal shunt (VPS) placement often necessitates gastrostomy for nutritional support. The sequence of these procedures is debated over concerns for shunt infection and displacement requiring revisional surgery as a consequence of gastrostomy.ObjectiveTo determine the optimal sequence of VPS shunt and gastrostomy tube placement in adults.MethodsIn an all-payer database, adult patients undergoing gastrostomy and VPS placement were identified within 15 days between January 2010 and October 2021. Patients were categorized as receiving gastrostomy before, on the same day as, or after shunt placement. The primary outcomes of this study were rates of revision and infection. All outcomes were evaluated within 30 months after index shunting.ResultsIn total, 3015 patients were identified as undergoing VPS and gastrostomy procedures within 15 days. After a 1:1:1 match, 1080 patient records were analyzed. Revision rates at 30 months were significantly lower among patients who received VPS and gastrostomy procedures on the same day compared with gastrostomy after VPS (odds ratio [OR] 0.61, 95% CI 0.39-0.96). In addition, patients who received gastrostomy before VPS compared with those after had lower revision rates (OR 0.61, 95% CI 0.39-0.96) and infection (OR 0.46, 95% CI 0.21-0.99). No significant differences were noted in mechanical complication or shunt displacement rates.ConclusionPatients requiring VPS and gastrostomy may benefit from undergoing both procedures concurrently or with gastrostomy before VPS placement, secondary to lower revision rates. Patients undergoing gastrostomy before VPS have the added benefit of decreased infection rates.Copyright © Congress of Neurological Surgeons 2023. All rights reserved.
