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.
To know more about the intra-gastric migration of the distal VPS catheter.
This systematic review of the literature aims to highlight the demographics, clinical characteristics, and outcome of the surgical procedures performed for the intra-gastric migration of the distal VPS catheter, clinically presented with or without trans-oral extrusion of the distal end of peritoneal/VPS catheter.
An online search was carried out for extraction/retrieval of published literature about the intra-gastric migration of the distal VPS catheter. PubMed, PubMed Central, ResearchGate, Google Scholar, and Google Images databases were searched using various terminology relating to the VPS complications. Manuscripts were retrieved from 1980 to December 2022. The selection of literature for the present review was done by assessing the titles, abstracts, and full texts of the manuscripts.
A total of n = 46 cases of intra-gastric migration of the distal VPS catheter clinically presented with or without peroral extrusion were recruited for the systematic review and were retrieved from the n = 46 manuscripts. Approximately sixty percent of them were children ≤ 5 years of age at the time of diagnosis of the complication mentioned above. In seventy-two percent of cases, this complication was detected within 24 mo after the VPS insertion/last shunt revision. Removal of the entire VPS catheter/removal of part of the distal/distal VPS catheter with or without external ventricular drainage was preferred by the authors. Percutaneous surgical removal of the entire or the distal VPS catheter with or without external ventricular drainage was a procedure of choice and was opted for n = 27 cases. For the management of VPS complications mentioned above, formal laparotomy was carried out only in n = 11 cases. In eighty-five percent of cases, the site of bowel perforation was the stomach. The site of bowel perforation was repaired only in n = 11 cases.
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. Formal exploration of the abdomen for the management of the VPS complication described above was neither done nor required in 70% of cases. In two-thirds of cases, the repair of the stomach/bowel perforation caused by the distal VPS catheter was not done and it healed after the removal of the distal shunt catheter from the stomach/bowel.
This systematic review revealed that the intra-gastric migration of the peritoneal end of a VPS catheter was more commonly reported in children than adults and older people. Intra-gastric migration with peroral extrusion of the distal VPS catheter was twice as commonly reported than the intra-gastric migration of the distal VPS catheter clinically presented without peroral extrusion. A high degree of clinical suspicion is required for the diagnosis of cases of an intra-gastric migration of the distal VPS catheter clinically presenting without trans-oral extrusion. The exact mechanism for the intra-gastric migration of the peritoneal end of the VPS catheter is not known and requires some specific experimental studies.
