About this study
Official title: Neo-angiogenesis in 3D Dynamic Responsive Implant for Inguinal Hernia Repair ProFlor
The investigation is aimed at specifically demonstrating the ingrowth of newly formed vascular elements within ProFlor, a 3D dynamic responsive implant for inguinal hernia repair
Read the detailed description
Biopsy specimen were excised at defined postoperative stages from patients who underwent hernia repair with the 3D prosthesis named ProFlor. Scope of the study was to determine the presence, quantity and quality of the vascular elements ingrowth within the implant fabric. Histology revealed the presence of multiple angiogenetic clusters that, starting from the early stage post-implantation, increased in number and degree of maturation. In the long term, the detected vascular components assumed the typical aspect of mature veins and arteries complete in all components. The development of fully developed vascular structures, ingrowing together with other components of the abdominal wall already described in literature, seems to finalize a regenerative response. This kind of behavior, being the expected result from a device intended for the cure of inguinal hernia and its degenerative source, seems to be coherent with the pathogenesis of the disease.

Questions about this trial
What is this clinical trial studying?
An observational study of Inguinal Hernia, run by University of Cagliari.

Who may be eligible to take part?
The sponsor lists 3 inclusion and 1 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: finished, as of the sponsor's last update on 10 Sep 2020. Status can change between updates, so confirm with the study contact before making plans.
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.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Ingrowth of Newly Formed Vascular Elements Within Hernia Implant ProFlor (time frame: 3-5 weeks post-implantation). The study lists 3 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 NCT04541316, which also lists 4 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 10 Sep 2020.
