About this study

Official title: Comparison of Symptomatic and Radiographic Outcomes of Paraesophageal Hernia Repair With and Without MatriStem Surgical Matrix

This is a prospective, case-matched, systematic follow up of up to 70 pre-existing patients whom underwent paraesophageal hernia repair between June 1, 2012 and September 30, 2016. Patients whom are willing to participate in the study will be asked to return for a one time follow up visit to reassess for hiatal hernia recurrence both symptomatically and radiologically to compare the efficacy of the use of MatriStem Surgical Matrix (ACell) mesh to other biologic meshes.

Read the detailed description

The participating "MatriStem" patients (N=35) will be matched to "control" patients who were treated surgically by Dr. Vic Velanovich or Dr. Michael Albrink for paraesophageal hernia with a biological mesh other than MatriStem Surgical Matrix (N=35) during the study timeframe at Tampa General Hospital. Patients will be matched by age (+ 5 years), gender, and operative approach (laparoscopic, laparotomy, or thoracic approach).

Study participation will require only one visit. Once the patient signs the consent form, operative details and the postoperative course will be reviewed retrospectively.

Visit 1 (≥ 12 months post-PEHR)

  1. Review the study with the subject and/or subject's legal representative, and obtain written informed consent and HIPAA authorization.
  2. Assign the subject a unique screening/enrollment number (assigned sequentially starting from 001).
  3. Pregnancy test if subject is of childbearing potential
  4. Confirm subject eligibility.
  5. Record demographics data, which includes date of birth, race, ethnicity, and gender.
  6. Record current clinical symptoms in relation to the HH.
  7. Record medications, including over-the-counter and herbal medications, taken postoperatively in relation to the HH.
  8. Record medical history with respect to the paraesophageal hernia prior to the surgical repair. If available, the following information will be recorded: hernia type, hernia size, organo-axial, or meso-axial rotation, and operative approach (laparoscopic, laparotomy, or thoracic approach).
  9. Record medical history with respect to the paraesophageal hernia after the surgical repair (size of mesh implant, length of surgery [calculated as the time from incision to wound closure], postoperative complications to include need for reoperation, mesh migration, reherniation, etc [from date of hospital discharge to study visit], and symptom frequency).
  10. Perform esophagogram at TGH.
  11. Administer GERD-HRQL symptom severity questionnaire.
  12. Administer SF-36 generic quality of life instrument.

Questions about this trial

What is this clinical trial studying?

An observational study of Paraesophageal Hernia, run by University of South Florida at 1 site in United States.

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 6 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 28 Mar 2019. 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 United States. 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.

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?

Rate of hernia recurrence (time frame: 12 months). 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 NCT03058731, 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 28 Mar 2019; AzTrials last refreshed its copy on 6 Nov 2026.
