Insights
Combining ventriculoperitoneal shunts (VPS) and percutaneous endoscopic gastrostomies (PEG) may increase VPS infection risk. Delaying PEG insertion for at least 10 days after VPS placement can reduce infection rates in neurosurgical patients.
Area of Science:
- Neurosurgery
- Gastroenterology
- Infectious Disease
Background:
- Combined use of ventriculoperitoneal shunts (VPS) and percutaneous endoscopic gastrostomies (PEG) is common in neurosurgical patients requiring enteral feeding.
- The safety and infection risk associated with simultaneous or sequential VPS and PEG insertion remain a concern.
- This study investigates the largest European series to date on combined VPS and PEG procedures.
Purpose of the Study:
- To determine the safety of combined VPS and PEG insertion.
- To assess the risk of ventriculoperitoneal shunt infection following percutaneous endoscopic gastrostomy placement.
- To provide evidence-based recommendations for the timing of PEG insertion in patients with VPS.
Main Methods:
- Retrospective review of 302 patients undergoing VPS insertion between 2002 and 2007.
- Analysis of 24 patients who subsequently received PEG insertion.
- Comparison of shunt infection rates in patients with and without PEG, and by timing of procedures.
Main Results:
- Five out of 24 patients (20.8%) developed a shunt infection after PEG insertion.
- This infection rate is significantly higher than the overall institutional rate of 7% (P = 0.017).
- No significant increase in infection was observed when PEG insertion was delayed by more than 10 days (2/14 patients).
Conclusions:
- Delaying PEG insertion for at least 10 days post-VPS placement may be prudent to minimize shunt infection risk.
- PEG insertion should not be avoided in stable patients with pre-existing VPS due to concerns about cerebrospinal fluid or shunt infection.
- Careful consideration of procedural timing is essential for patient safety in combined VPS and PEG cases.
Background:
We report the largest European series of patients in whom both ventriculoperitoneal shunts (VPS) and percutaneous endoscopic gastrostomies (PEG) have been inserted with the aim of determining if this combination is safe or if there is an increased risk of VPS infection.
Patients And Methods:
The paper and electronic records of 302 patients who had a ventriculoperitoneal (VP) shunt inserted in the regional Neurosciences unit at Salford Royal NHS Foundation Trust between 2002 and 2007 were reviewed.
Results:
A total of 24 patients with VP shunts had 26 PEG inserted. Thirteen PEG were inserted in 11 patients with a pre-existing VP shunt. The median age was 58 years (21-77 Yrs) with seven male and 17 female patients. In total, five patients developed a shunt infection (20.8%) compared to the overall rate of VP shunt infection for Salford Royal NHS Foundation Trust of 7% (P = 0.017). The increase in number of VP shunt infections when the procedures were done more than 10 days apart (2/14) was not significant (P = 0.25).
Conclusion:
In patients who need long-term enteral feeding following a VP shunt insertion it may be prudent to delay insertion of a PEG for at least 10 days to reduce VPS infection. In stable patients who have had a VP shunt inserted on previous hospital admissions PEG insertion need not be avoided because of concern regarding cerebrospinal fluid or shunt infection.
