  • Adult men and women, age 18 years of age
  • Diagnosis of perianal disease with tissue defect or chronic wound
  • Underwent, or candidate for, surgery for perianal disease with colorectal surgery attending at UCSD

About this study

This study will compare healing and surgical outcomes in patients with chronic perianal disease treated with Adipose-derived Stem Cells (ASCs) to outcomes in patients treated in traditional surgical techniques without ASCs. The study will perform retrospective medical record analysis to clinically characterize patients that have undergone these surgical procedures and compare follow-up data and disease status to determine efficacy of treatment with ASCs compared to similar treatments without the use of ASCs. This will help determine overall efficacy of the treatment as well as determine patient characteristics that may predict treatment success. The study will also prospectively recruit patients with perianal disease that are planning to receive treatment with ASCs, and analyze their outcomes in the same way. Medical record review of outcomes in patients with perianal disease that received treatment with ASCs compared to those that did not will determine efficacy of this procedure.

Read the detailed description

Specific Aims:

  1. Conduct a retrospective review of health information data from patients who have undergone surgery with a colorectal surgery attending at the University of California San Diego, including surgical treatment of perianal fistulas or other chronic perianal diseases, with or without injection of lipoaspirate containing adipose-derived stem cells. Patient data from December 2013 to April 1, 2018, will be obtained, with parameters including date of birth, sex, date of surgery, medical history, surgical history, laboratory values, perioperative data such as blood loss, length of surgery, operative complications, readmissions, and long-term complications and status of disease.
  2. Conduct an observational study comparing outcomes of patients that plan to undergo treatment of perianal disease using ASCs compared to those that do not use ASCs. Patients identified as candidates for the procedure by the colorectal surgeons and are planning to undergo the procedure will give informed consent and be recruited into the study. Participants will undergo isolation of ASCs using the REVOLVE ™ System and injection of ASCs into perianal wounds. Clinical data will be analyzed to determine efficacy of the procedure as a means of treating perianal disease.
  3. Use the above data to clinically characterize patients that undergo this surgical procedure and what patient characteristics may determine outcomes. Comparing follow-up data and disease status will determine efficacy of treatment with adipose-derived stem cells compared to similar treatments without the use of stem cells.
Being tested
Injection of adipose-derived stem cells into perianal fistula

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Injection of adipose-derived stem cells into perianal fistulaProcedure or surgery

    The plastic surgery team will perform fat graft harvest. Tumescent solution will be infiltrated into the area of liposuction, generally the abdomen, flanks, or thighs. Approximately a00ml of liposuction aspirate will be retrieved. It will be washed and condensed down to about 5-25 ml of good-quality fat graft using the REVOLVE System by Acelity. This will then be loaded into a syringe fitted with an injection cannula. The colorectal surgeon will perform an exam under anesthesia and determine if any additional procedure such as ligation of fistula tract, fistulotomy, endorectal advancement flap, or seton placement/exchange is needed. Severity of disease at time of surgery will be recorded by the attending surgeon. Following any indicated procedure, the lipoaspirate will be injected into the soft tissues around the fistula tract.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Improvement in perianal disease after the procedure

    Patients will have routine post-operative follow up in with a colorectal surgeon and/or their clinical Nurse Practitioner 2-4 weeks following the procedure in colorectal surgery clinic. At that appointment, the timing of additional postoperative appointments or procedures will be determined. Clinical data and status of the disease will be documented by the attending surgeon and subsequently collected from the medical record. Fistula healing will be assessed clinically 3 months after the procedure has been performed. The patient will be asked to complete the Perianal Disease Activity Index (PDAI)questionnaire both prior to intervention as well as at a post-operative appointment 3 months following the procedure to asses for improvement of symptoms. The PDAI is a validated instrument to assess the severity of perianal disease . We will also perform MRIs prior to repair and after to confirm resolution of abscess cavities and fistulae.

    Measured: 4 months

Questions about this trial

What is this clinical trial studying?

An observational study of Perianal Fistula and Crohn Disease, run by University of California, San Diego 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 6 inclusion and 3 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 27 Apr 2021. 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?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Samuel Eisenstein, MD (2035602213, seisenstein@ucsd.edu), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Improvement in perianal disease after the procedure (time frame: 4 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 27 Apr 2021.
