About this study
Official title: Clinical Study on Improvement of Peritoneal Catheter Placement in Ventriculoperitoneal Shunt Surgery With a Splitable Trocar
This study is a phase I/IIa, single-center, open-labeled, randomized, controlled clinical trial. The aim of this study is to evaluate the safety and efficacy of a modified ventriculoperitoneal catheter placement using a splitable trocar for ventriculoperitoneal shunt.
Read the detailed description
This study is a phase I/IIa, single-center, open-labeled, randomized, controlled clinical trial. Patients hospitalized with hydrocephalus will be enrolled and randomly allocated into open mini-laparotomy group (OLG) or abdominal puncture group (APG) for insertion of the peritoneal catheter. Observe will followed for up to at least 6 months after surgery. The primary endpoint is the rate of overall shunt complication or failure within the first 6 months after surgery, and duration of the abdominal catheterization. The secondary endpoints are rate of distal shunt failure, the overall incidence of various adverse reactions, abdominal incision size, analgesic use as evaluated on Day 5 postoperatively, duration of hospital stay. Moreover, neurological function of patients (mRS, maxillary hydrocephalus scale) and CT measurement of Even index will also be evaluated.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Open Mini-LaparotomyProcedure or surgery
A 5-cm paraumbilical skin is made, and the abdominal wall is incised in layers. The distal catheter tip is inserted into the peritoneal cavity in a craniocaudal direction, and the abdominal wound is sutured in layers.
Abdominal PunctureProcedure or surgery
An about 0.5-cm paraumbilical incision made to allow introduction of a splitable trocar. The trocar is pierced through the abdominal wall into the abdominal cavity. Pull out the puncture cone, and adjust the trocar towards the pelvis. The distal catheter tip is inserted into the peritoneal cavity through the puncture cannula. Then the splitable puncture cannula is split apart and removed. The skin incision requires only one stitch.

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing Open Mini-Laparotomy and Abdominal Puncture in people with Hydrocephalus, run by Southern Medical University, China at 1 site in China.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 1 Aug 2022. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this combined phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Zhen-Zhou Chen, Dr. (+86-2062782768, czz1020@163.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Rate of shunt failure (time frame: 6 months). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT05476874, which also lists 3 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 1 Aug 2022.
