Abstract
BACKGROUND

Intra-gastric migration of the distal ventriculoperitoneal shunt (VPS) catheter clinically presenting with or without trans-oral extrusion is one of the rare complications of VPS catheter insertion.

AIM

To identify the demographics, clinical presentation, clinical findings, and results of surgical therapy offered for the treatment of intra-gastric migration of the distal VPS catheter, clinically presented with or without trans-oral extrusion.

METHODS

An online search was performed for the extraction/retrieval of the published/ available literature pertaining to the above-mentioned VPS complication. Manuscripts were searched from PubMed, PMC (PubMed Central), ResearchGate, and Google Scholar databases using various terminology relating to the VPS complications. The first case of migration of a VPS catheter into the stomach was reported in the year 1980, and the data were retrieved from 1980 to December 2022. Cases were categorized into two groups; Group A: Cases who had migration of the distal VPS catheter into the stomach and clinically presented with trans-oral extrusion of the same, and Group B: Cases who had migration of the distal VPS catheter into the stomach, but presented without trans-oral extrusion.

RESULTS

A total of n = 46 cases (n = 27; 58.69% male, and n = 19; 41.3% females) were recruited for the systematic review. Group A included n = 32, and Group B n = 14 cases. Congenital hydrocephalus was the indication for the primary VPS insertion for approximately half of the (n = 22) cases. Approximately sixty percent (n = 27) of them were children ≤ 5 years of age at the time of the diagnosis of the complication mentioned above. In seventy-two percent (n = 33) cases, this complication was detected within 24 mo after the VPS insertion/last shunt revision. Clinical diagnosis was evident for the entire group A cases. Various diagnostic modalities were used to confirm the diagnosis for Group B cases. Various surgical procedures were offered for the management of the complication in n = 43 cases of both Groups. In two instances, intra-gastric migration of the distal VPS catheter was detected during the autopsy. This review documented four deaths.

CONCLUSION

Intra-gastric migration of the peritoneal end of a VPS catheter is one of the rare complications of VPS catheter implantation done for the treatment of hydrocephalus across all age groups. It was more frequently reported in children, although also reported in adults and older people. A very high degree of clinical suspicion is required for the diagnosis of a case of an intra-gastric migration of the distal VPS catheter clinically presenting without trans-oral extrusion.

Core Tip: This systematic review included n = 46 cases of intra-gastric migration of the peritoneal end of a ventriculoperitoneal shunt (VPS) catheter. Thirty-two cases clinically presented with the peroral extrusion of the distal VPS catheter. The remaining n = 14 cases clinically presented with other symptoms but without peroral extrusion of the distal VPS catheter. Sixty percent were children ≤ 5 years of age at the time of diagnosis of VPS complication mentioned above. In more than two-thirds of cases, the VPS complication was evident within 24 mo after the primary VPS insertion/last VPS revision. The demographics, indications for the primary/initial VPS insertion, age distribution at the time of VPS insertion and diagnosis of the VPS complication, the interval, and the surgical procedures carried out by the various authors for the above-described VPS complication are described in the manuscript.
