Ventricular gallbladder shunts: an alternative procedure in hydrocephalus.

Area of Science:

• Pediatric Neurosurgery
• Surgical Innovation
• Hydrocephalus Management

Background:

• Hydrocephalus is common in infants, often treated with ventriculoperitoneal (VP) or ventriculoatrial (VA) shunts.
• Previous alternative distal shunt sites include the stomach, ureter, and fallopian tube.
• VP and VA shunts can be associated with complications like infection and malfunction.

Purpose of the Study:

• To report the experience with ventricular gallbladder shunts (VGB) in pediatric patients.
• To evaluate the efficacy and long-term outcomes of VGB shunts.
• To identify indications and potential complications of VGB shunts.

Main Methods:

• A retrospective review of 25 children (13 girls, 12 boys) aged 6 months to 16 years who underwent VGB shunt placement between 1970 and 1985.
• Analysis of diagnoses including meningomyelocoele, congenital hydrocephalus, postmeningitic complications, intracranial tumors, and intraventricular hemorrhage.
• Indications for VGB shunts included VP/VA shunt infections, ascites, and distal shunt malfunction.

Main Results:

• Fifteen shunts remained functional at long-term follow-up in 70% of available patients (20/25).
• Early shunt failure occurred in 3 patients due to proximal obstruction or gallbladder atony.
• One case of gallbladder atony was successfully treated with cholecystokinin; two required shunt revision.

Conclusions:

• The ventricular gallbladder shunt (VGB) procedure is a valuable alternative for hydrocephalus management.
• VGB shunts are particularly useful in patients where intraperitoneal and intravascular shunts are not feasible.
• Long-term functional success rates suggest VGB shunts are a viable option in complex cases.
