Insights
Simultaneous abdominal surgery or wound contamination during ventriculoperitoneal (VP) shunt placement did not significantly increase the risk of 30-day post-operative complications in pediatric patients. This study found no increased risk for overall, infectious, or non-infectious complications.
Area of Science:
- Neurosurgery
- Pediatric Surgery
- Surgical Quality Improvement
Background:
- Ventriculoperitoneal (VP) shunts are crucial for managing hydrocephalus in pediatric patients.
- Concerns exist regarding potential increased risks of shunt complications when VP shunt placement coincides with abdominal surgeries or involves contaminated wounds.
- Assessing these risks is vital for optimizing patient safety and surgical protocols.
Purpose of the Study:
- To determine if performing simultaneous abdominal surgery during VP shunt placement increases complication rates.
- To evaluate whether wound contamination at the time of VP shunt placement is associated with higher complication rates.
- To identify potential risk factors for VP shunt complications in pediatric patients.
Main Methods:
- A retrospective analysis of pediatric patients undergoing VP shunt placement was conducted using the National Surgical Quality Improvement Program Pediatric database.
- Patients were compared based on whether they had simultaneous abdominal surgery versus those who did not.
- Comparison was also made between wound classifications: clean/clean-contaminated versus contaminated/dirty, using 1:5 case-control matching for adjusted analysis.
Main Results:
- No significant difference in overall, infectious, or non-infectious shunt complications was observed between patients with simultaneous abdominal surgery and controls (p>0.05).
- Rates of shunt infection were not significantly different between clean/clean-contaminated wounds and contaminated/dirty wounds (p=0.613).
- The study analyzed 2715 VP shunt placements, with specific matched cohorts for surgical timing and wound classification.
Conclusions:
- Simultaneous abdominal surgery at the time of VP shunt placement does not appear to elevate the risk of 30-day post-operative complications.
- Wound contamination classification (clean vs. contaminated) did not significantly correlate with increased shunt infection rates in this cohort.
- These findings suggest that VP shunt placement can be performed concurrently with abdominal procedures without a statistically significant increase in adverse outcomes.
Purpose:
To evaluate whether simultaneous abdominal surgery or wound contamination at the time of ventriculoperitoneal (VP) shunt placement are associated with increased shunt complications.
Methods:
Pediatric patients who underwent VP shunt placement were identified using the National Surgical Quality Improvement Program Pediatric database. VP shunt complication rates were compared between patients who underwent simultaneous abdominal surgeries at the time of VP shunt placement vs those who did not and between those with clean/clean-contaminated and contaminated/dirty wound classifications. Adjusted analysis was performed using 1:5 case-control matching.
Results:
Among 2715 patients who underwent VP shunt placement, 21 had simultaneous abdominal procedures and were matched with 105 control patients. No significant difference was found in overall (34.3 vs 14.3%, p = 0.07), infectious (8.6 vs 4.8%, p = 1.000), or non-infectious (25.7 vs 9.5%, p = 0.156) shunt complications in the simultaneous vs non-simultaneous group, respectively. In a separate analysis of wound classification, 12 patients with contaminated/dirty wounds were matched with 60 patients with clean/clean-contaminated wounds. The rates of shunt infections for clean/clean-contaminated and contaminated/dirty cases were 10.0 and 16.7%, respectively (p = 0.613).
Conclusion:
In our matched case-control study, neither simultaneous abdominal surgery nor wound contamination at the time of VP shunt placement demonstrated significant increased risk of 30-day post-operative complication.
