Ventriculogallbladder shunts in pediatric patients.

Area of Science:

• Pediatric Neurosurgery
• Surgical Innovation
• Hydrocephalus Management

Background:

• Ventriculoperitoneal (VP) shunts are standard for hydrocephalus but can fail due to peritoneal absorption issues or abdominal surgeries.
• Alternative distal termini are needed for patients with compromised peritoneal cavities.

Purpose of the Study:

• To describe the clinical protocol and outcomes of ventriculogallbladder (VGB) shunts in pediatric patients.
• To evaluate VGB shunts as an alternative to VP shunts when the peritoneum is unsuitable.

Main Methods:

• Eighteen pediatric patients received VGB shunts due to VP shunt malfunction (peritoneal failure) or prior abdominal surgeries.
• Preoperative gallbladder imaging (ultrasound or CT) was performed.
• Procedures involved open laparotomy for precise distal catheter placement and gallbladder wall anchoring by pediatric neurosurgical and general surgical teams.

Main Results:

• 13 of 18 patients had functional VGB shunts at a mean follow-up of 2.1 years.
• Three early/late malfunctions occurred (sludge, common bile duct obstruction, gallbladder stones), successfully converted to VP shunts.
• Two shunt infections were successfully treated; two patients required repeat VGB shunt conversions.

Conclusions:

• Ventriculogallbladder shunts are a viable option for pediatric hydrocephalus when the peritoneal cavity is not usable.
• Careful patient selection and surgical technique are crucial for VGB shunt success.
