We read with great interest the article by Kutty et al. in the recent issue of your journal. I would like to commend the authors for their endeavor to bring this data from developing countries, but at the same time have the following comments to offer, explanation to which will benefit the readership of the journal.
- The authors compare only two variables as the outcome of interest in the form of mortality and conversion to ventriculoperitoneal shunt (VPS) and labeled them as “good” and “bad.” This classification seems to be too oversimplified. Neurodevelopmental outcome and arrest of the hydrocephalus of the preterm neonates undergoing shunt surgery are very crucial outcomes and should have been enlisted as one of the outcome measures.
- Babies having ventriculosubgaleal (VSG) shunt may remain more stable and in better condition than those with VP shunt. In these conditions, if the neurodevelopmental outcome is acceptable and there is no further progression of hydrocephalus, then VP shunt may not be warranted. Hence, considering VP shunt conversion as an outcome may be fallacious.
- The authors have not defined the criteria to be fulfilled for conversion to VPS. In the absence of predefined criteria, the comparison of time to VPS may be very heterogeneous and noncomparable.
- It would have been reasonable to compare shunt revision/malfunction rates and other complications among the two groups.
- The inclusion of patients in whom VSG was inserted in another hospital may introduce significant heterogeneity as the technique, expertise, and postoperative care differ across various institutions.
- Currently, there is insufficient evidence to recommend specific parameters such as cerebrospinal fluid sugar/protein/cell count to direct the timing of shunt placement in premature infants with hydrocephalus. So, what was the rationale for considering protein >500 mg/dL as sole criteria for VPS?
