Laparoscopic ventricular-cholecystic shunt

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.

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

OBJECTIVE

The management of hydrocephalus resulting from intraventricular hemorrhage related to extreme prematurity remains demanding. Given the complexities of controlling hydrocephalus in this population, less commonly used procedures may be required. The authors examined the utility of ventriculogallbladder (VGB) shunts in a series of such children.

METHODS

The authors retrospectively reviewed the medical records of all children who underwent surgery for hydrocephalus in the period from 2011 through 2019 at Children's Healthcare of Atlanta. Six patients who underwent VGB shunt placement were identified among a larger cohort of 609 patients who had either a new shunt or a newly changed distal terminus site. The authors present an analysis of this series, including a case of laparoscopy-assisted distal VGB shunt revision.

RESULTS

The mean age at initial shunt placement was 5.1 months (range 3.0-9.4 months), with patients undergoing a mean of 11.8 shunt procedures (range 5-17) prior to the initial VGB shunt placement at a mean age of 5.3 years (range 7.9 months-12.8 years). All 6 patients with VGB shunt placement had hydrocephalus related to extreme prematurity (gestational age < 28 weeks). At the time of VGB shunt placement, all had complex medical and surgical histories, including poor venous access due to congenital or iatrogenic thrombosis or thrombophlebitis and a peritoneum hostile to distal shunt placement related to severe necrotizing enterocolitis. VGB complications included 1 case of shunt infection, identified at postoperative day 6, and 2 cases of distal shunt failure due to retraction of the distal end of the VGB shunt. In all, there were 3 conversions back to ventriculoperitoneal or ventriculoatrial shunts due to the 2 previously mentioned complications, plus 1 patient who outgrew their initial VGB shunt. Three of 6 patients remain with a VGB shunt, including 1 who underwent laparoscopy-assisted distal shunt revision 110.5 months after initial VGB shunt insertion.

CONCLUSIONS

Placement of VGB shunts should be considered in the armamentarium of procedures that may be used in the particularly difficult cohort of children with hydrocephalus related to extreme prematurity. VGB shunts show utility as both a definitive treatment and as a "bridge" procedure until the patient is larger and comorbid abdominal and/or vascular issues have resolved sufficiently to allow conversion back to ventriculoperitoneal or ventriculoatrial shunts, if needed.

Evaluation of the ventriculocholecystic shunt-an overview of present practice in adult and pediatric hydrocephalus

In the context of hydrocephalus, there are a multitude of therapeutic options that can be explored in order to improve patient outcomes. Although the peritoneum is the current elected clinical solution, various receptacles have been utilized when experiencing contraindications. Along with the ventriculoatrial or ventriculopleural, the ventriculocholecystic shunt was also described as an alternative. In order to make a decision on a place for drainage, the surgeon must be knowledgeable on details from modern literature. The main target of this review was to summarize the currently available information on this topic and assess the status of the gallbladder as a viable option for cerebrospinal fluid diversion.
