Utility of ventriculogallbladder shunts in complex cases of hydrocephalus related to extreme prematurity

Ventriculo-gallbladder shunt: case series and literature review

BACKGROUND

The ventriculoperitoneal shunt (VPS) is the gold-standard surgical technique to treat hypertensive hydrocephalus; however, it may fail in 20 to 70% of cases. The present study shows an alternative for patients with contraindications to VPS.

METHODS

A case series of nine patients. The medical records of all patients under 17 years of age who underwent ventriculo-gallbladder (VGB) shunt at a pediatric hospital from January 2014 to October 2022 were reviewed.

RESULTS

There were 6 (66.7%) males and 3 (33.3%) females. The average age of 73.6 months or 6.1 years at the time of surgery. They had undergone, on average, 5.1 VPS reviews before the VGB shunt. Five (55.5%) had complications of VGB shunt: infection (11.1%), atony (11.1%), hypodrainage (11.1%), and ventriculoenteric fistula (22.2%); all these patients got better at surgical reapproach, and in two of them, the VGB shunt was re-implanted.

CONCLUSION

This case series shows a lower risk of death and a similar risk of complications compared to other alternative shunts. This article spotlighted VGB as a viable alternative when VPS fails or has contraindications.

Can we consider ventriculo-gallbladder shunt a first-line treatment in selected patients? Case report of a successful management

INTRODUCTION

Ventriculo-gallbladder shunt (VGS) has been recognized as a last-resort alternative to treat hydrocephalus when the peritoneum and/or other distal sites can no longer receive shunts. In some specific conditions, it may be conceded as a first-line treatment.

CASE PRESENTATION

We report the case of a 6-month-old girl with progressive post-hemorrhagic hydrocephalus who presented a concomitant chronic abdominal symptom. Specific investigations ruled out acute infection and led to the diagnosis of chronic appendicitis. Both problems were managed in a one-stage salvage procedure consisting of laparotomy sanctioning to treat the abdominal pathology and seize the opportunity to perform a VGS as a first option since the abdomen is prone to ventriculoperitoneal shunt (VPS) failure.

CONCLUSION

Only few cases have reported the use of VGS as the first option to handle uncommon complex cases due to abdominal or cerebrospinal fluid (CSF) conditions. We wish to draw attention to VGS as an effective procedure not only in children with multiple shunt failures but also as first-line management in some selected cases.
