Migration of the distal ventriculoperitoneal shunt catheter into the stomach with or without trans-oral extrusion:A systematic literature review and meta-analysis

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 transoral extrusion.

Should a VP or LP Shunt be Used for the Treatment of Pseudotumorcerebri in Adults?

Introduction: Pseudotumorcerebri(PTC) is a condition characterized by false brain tumor symptoms, caused by high intracranial pressure (ICP). Treatment options include medication, weight loss, surgery, and shunting. Shunting, either ventriculoperitoneal (VP) or lumboperitoneal (LP), emerged as the preferred method of treatment, but there is an ongoing debate as to which technique should be prioritized. The aim of this study is to gather additional evidence to determine the optimal type of shunt for treating PTC. Materials and Methods: Ninety patients with PTC were studied at Damascus University between 2016 and 2021. The study monitored symptoms before and after treatment, with improvement related to the technique used (VP or LP shunts). Of all patients, 83 were women and 7 were men. In addition, complications were analyzed. Results: Both shunts showed similar postoperative rates of symptom improvement, but VP shunts were utilized more frequently overall in this study. Patients who received LP shunt surgery had a higher rate of postoperative complications compared to those who received VP shunt surgery, but the chi-squared analysis did not provide sufficient evidence to confirm a significant relationship between the type of surgery and the occurrence of postoperative complications. Conclusion: Despite ongoing controversy about the optimal treatment for benign intracranial hypertension (BTC), most authors approved the trend of using VP (ventriculoperitoneal) shunts, given a lower rate of complications. However, there is no statistically significant difference between outcomes of VP and LP (lumboperitoneal) shunting techniques, according to our research.

Abdominal Cerebrospinal Fluid Pseudocyst—A Rare Complication of Ventriculoperitoneal Shunt

An abdominal cerebrospinal fluid pseudocyst is a rare complication of ventriculoperitoneal shunt. Several theories have been suggested to explain its occurrence. The main symptoms are painful abdominal distension and vomiting, abdominal distension on examination, as abdominal ultrasound and computed tomography confirm its diagnosis. The treatment involves drainage associated with drain relocation and resection of the pseudocyst’s wall. We report two patients diagnosed with this condition who underwent surgical treatment. The first patient had an unremarkable 12-month follow-up, while the second died on the seventh postoperative day due to intravascular disseminated coagulation. In these patients, the cause has not been identified;however, an infection cannot be ruled out.

Is percutaneous endoscopic gastrostomy tube placement safe in patients with ventriculoperitoneal shunts?

AIM:To investigate whether percutaneous endoscopic gastrostomy (PEG) tube placement is safe in patients with ventriculoperitoneal (VP) shunts.METHODS: This was a retrospective study of all patients undergoing PEG insertion at our institution between June 1999 and June 2006. Post-PEG complications were compared between two groups according to the presence or absence of VP shunts. VP shunt infection rates, the interval between PEG placement and VP shunt catheter insertion, and long-term follow-up were also investigated.RESULTS: Fifty-five patients qualified for the study. Seven patients (12.7%) had pre-existing VP shunts. All patients received prophylactic antibiotics. The complication rate did not differ between VP shunt patients undergoing PEG (PEG/VP group) and non-VP shunt patients undergoing PEG (control group) [1 (14.3%) vs 6 (12.5%), P=1.000]. All patients in the PEG/VP group had undergone VP shunt insertion prior to PEG placement. The mean interval between VP shunt insertion and PEG placement was 308.7 d (range, 65-831 d). The mean follow-up duration in the PEG/VP group was 6.4 mo (range, 1-15 mo). There were no VP shunt infections, although one patient in the PEG/VP group developed a minor peristomal infection during follow-up.CONCLUSION: Complications following PEG placement in patients with VP shunts were infrequent in this study.

Risk factors for delayed intracranial hemorrhage secondary to ventriculoperitoneal shunt:A retrospective study

BACKGROUND Delayed intracranial hemorrhage(DICH),a potential complication of ventriculoperitoneal(VP)shunts,has been associated with high mortality,but its risk factors are still unclear.AIM To investigate the risk factors of DICH after VP shunts.METHODS We compared the demographic and clinical characteristics of DICH and non-DICH adult patients with VP shunts between January 2016 and December 2020.RESULTS The 159 adult VP shunt patients were divided into 2 groups according to the development of DICH:the DICH group(n=26)and the non-DICH group(n=133).No statistically significant difference was found in age,sex,laboratory examination characteristics or preoperative modified Rankin Scale(mRS)score between the DICH and non-DICH groups(P>0.05);however,a history of an external ventricular drain(EVD)[P=0.045;odds ratio(OR):2.814;95%CI:1.024-7.730]and postoperative brain edema around the catheter(P<0.01;OR:8.397;95%CI:3.043-23.171)were associated with a high risk of DICH.A comparison of preoperative mRS scores between the DICH group and the non-DICH group showed no significant difference(P=0.553),while a significant difference was found in the postoperative mRS scores at the 3-mo follow-up visit(P=0.024).CONCLUSION A history of EVD and postoperative brain edema around the catheter are independent risk factors for DICH in VP shunt patients.DICH patients with a high mRS score are vulnerable to poor clinical outcomes.

Spinal Anesthesia in Infant with Ventriculoperitoneal Shunt: A Case Report of Inguinal Hernia Repair

Gigantic Abdominal Pseudocyst: An Unusual Evolution of the Ventriculoperitoneal Shunt

Background: The ventriculoperitoneal (VPS) shunt is the most common procedure in the treatment of hydrocephalus in children. Abdominal cerebrospinal fluid pseudocysts are a rare complication of the ventriculoperitoneal shunt with an incidence ranging from less than 1% to 10% and are more prevalent in children. The malfunction of the ventriculoperitoneal shunt can cause headaches, nausea, vomiting, altered level of consciousness and abdominal pain due to the accumulation of cerebrospinal fluid. There is no consensus on which type of treatment is better in this case, but there are several available methods. Aim: To report an unusual case of a giant abdominal cerebrospinal fluid pseudocyst as a complication of the VPS. Case Presentation: Female 1 y/3 months old patient, less than 7 kg, that has been diagnosed with hydrocephalus prenatally, confirmed postnatally associated with an esophageal atresia and distal tracheoesophageal fistula (AE/FTE, Gross III), was admitted to our service with progressive abdominal distention without obstructive intestinal signs or peritoneal inflammatory signs. The CT scan of the abdomen showed a large liquid collection (estimated volume of 600 ml), centered on the umbilical region, diagnosed as a giant abdominal cerebrospinal fluid (CSF) pseudocyst from the VPS. All of data and information were obtained from her medical records at the infirmary of the Conjunto Hospitalar de Sorocaba (CHS), São Paulo. Conclusion: Abdominal CSF as a cause of these giant pseudocysts should be considered as a diagnostic hypothesis for cases of large abdominal distensions without intestinal involvement in patients with a VPS. This research did not receive any specific grant from funding agencies in the public, commercial, or not-for-profit sectors.

Usage of neuronavigation system to treat a case of traumatic acute subdural hematoma after two-side ventriculoperitoneal shunt

Traumatic acute subdural hematoma is one of the most lethal causes of head injuries,which leads to high mortality.While combined diseases always make it more intractable for the treatment.We present a case of a 68-year-old female patient with traumatic acute subdural hematoma combined with hydrocephalus after ventriculoperitoneal shunt assisted by the neuronavigation system in January 12,2017.She was undergone ventriculoperitoneal shunt 6 years and 5 months ago on two sides respectively because of hydrocephalus,with the ventriculoperitoneal shunt device on the right side out of work.The initial neurological examination showed a Glasgow Coma Scale of E2V1M5 with no papillary defect.A CT scan of the head revealed a left homogeneously hyperdense and subdural hematoma,with compression of the lateral ventricle(2.6 cm thick)and a 0.5 cm midline shift.To protect the ventriculoperitoneal shunt device,we used neuronavigation system to precisely mark the relative location of the device and“invisible”subdural hematoma,thus to design a perfect incision preoperatively.Subsequently,evacuation of the subdural hematoma was performed via craniotomy without damaging the ventriculoperitoneal shunt device.Postoperative CT of the head showed totally removing of the subdural hematoma.The patient recovered three months later.With the assistant of neuronavigation system,it is much easier for the preoperative planning and to reduce the surgical risk.Our case gives a clue that more approaches can be considered when encountering acute head trauma with the complicated combined diseases.
