Re-treatment From a Phase I Study of MSC-AFP in Patients With Perianal Fistulas

Perianal FistulaCryptoglandular Perianal Fistula1 more

This study is an extension to re-treat partial and non-responders from the previously approved Phase 1 MCS-AFP protocols IRB #12-009716 (Crohn's Disease perianal fistulas) and 15-003200 (cryptoglandular perianal fistulas).

Study on the Treatment of Anal Fistulas Using Alofisel Versus Fat Autologous Stem Cells

Crohn DiseaseAnal Fistula

One of the newest and most innovative medicinal approaches is cell therapy. Several clinical trials and experimental investigations have looked into the feasibility of treating CD-related fistulas with stem cells. The current indication for ALOFISEL® (active ingredient: Darvadstrocel) is the treatment of difficult perianal Crohn's fistulas that have not responded well to at least one conventional therapy or biotherapy. This brand-new cell therapy medication is created using amplified allogeneic human adult mesenchymal stem cells from adipose tissue (ADSC). The supplier mandates that two patients be booked for a single dose of ALOFISEL® due to the medication's expensive price-roughly €54,000 for a single dose of 120 million-which cannot be stored once thawed. Only one of the two patients receives therapy; the other serves as the backup patient. By doing this, another "back-up" patient who might receive no care at all is avoided. An developing alternate approach to allogeneic ADSC injection for the treatment of complicated anal fistulas in CD is autologous fat injection. In recent years, autologous fat grafts have been the subject of in-depth research. They are popular because it is simple to get clinical samples (lipoaspirate, adipose tissue), and because there are a lot of ADSCs in adipose tissue. Additionally, ADSCs show strong immunomodulatory and regenerative capacities. We would wish to compare the effectiveness of these two injection kinds on perianal fistulas as part of our care of CD.

Efficacy and Safety of Adipose Stem Cells to Treat Complex Perianal Fistulas Not Associated to Crohn´s...

Anal Fistula

Anal fistula is defined as an abnormal communication between the anal canal and the perianal skin. Adipose-derived stem cells are a new therapy for the closure of these fistulas. This study will test the safety and efficacy of ASCs (adipose stem cells) in the treatment of patients without Crohn´s disease.

Stem Cell Fistula Plug in Cryptoglandular Perianal Fistulas (MSC-AFP)

Perianal FistulaCryptoglandular Perianal Fistula

The investigators propose to study the safety of autologous mesenchymal stromal cell transfer using a biomatrix (the Gore Fistula Plug) in a Phase I study using a single dose of 20 million cells. 15 adult patients, ages 18 years and older with cryptoglandular fistulas will be enrolled. Subjects will undergo standard adjuvant therapy including drainage of infection and placement of a draining seton. Six weeks post placement of the draining seton, the seton will be replaced with the MSC loaded Gore Fistula Plug; fistula plug as per current clinical practice. The subjects will be subsequently followed for fistula response and closure for 24 months. This is an autologous product derived from the patient and used only for the same patient.

Pre-Emptive Analgesia in Ano-Rectal Surgery

HemorrhoidsFissure in Ano2 more

The perianal region is the region around the anus. Administering a pain medication before a surgery starts is called preemptive analgesia. In some studies, this technique has been shown to be an effective way to reduce the pain that a patient experiences in the post-operative timeframe to a greater extent than would be expected simply from the pain medications alone. One theory of why this occurs suggests that the preemptive analgesia desensitizes brain and nerves to pain, thereby decreasing the response to painful stimuli, like surgery when they occur. This leads to a decrease in the amount of narcotic pain medication required after the procedure, which leads to less side effects and a quicker return to normal functioning. As perianal surgeries do not usually include a long stay in the hospital, controlling post-procedure pain is a priority. The use of preemptive analgesia is in other types of surgeries, such as orthopedics, is well established, but as the perianal region has not been well studied, its use is not the standard of care. This type of analgesia uses a combination of medications that are already in use for post-operative and non-operative pain control and administers them orally prior to the patient undergoing general anesthesia. The side effects of the medications are the same as if they had been given after surgery or for non-surgical pain. The concept of preemptive analgesia is established in other types of surgeries and it has solid basic science to support its use. The purpose of this randomized, double-blind, placebo controlled study is to determine if patients undergoing perianal surgeries could benefit from preemptive pain control. The primary outcome will be whether patients experience less post-operative pain. Patient post-operative consumption and latency until use of narcotic pain medication will be the secondary outcomes. The investigators believe that the patients receiving pain medications before their operation will require less pain medication after surgery, with minimal increased risk to the patient.

Adipose Derived Mesenchymal Stem Cell Characteristics in Anal Fistulas

Perianal FistulaAdipose Tissue1 more

This study investigated the cellular and molecular characteristics of AT-MSCs obtained from autologous AT therapy in patients with high transphincteric perianal fistulas of crytoglandular origin. Adipose tissue was injected into anal fistulas. Characteristics of adipose tissue mesenchymal stemcells (AT-MSC) was investigated and compared in patients with fistula that healed after the treatment (responders) to patients who failed to heal (non-responders)

Comparison of Prolene Thread Seton Vs Silk Thread Seton for the Treatment of Perianal Fistula

Perianal Fistula

It is a randomized control trial in which we will treat the patients with perianal fistula with seton placement. We will divide the patients in two groups. Group I will be treated with silk seton and Group II will be treated with prolene setone. The outcome will be then followed as fistula healing and recurrence.

LIFT With or Without Injection of BM-MNCs

Anal Fistula

To improve the outcome of LIFT, some authors used a combined approach of LIFT. Pooled analysis of seven studies including 192 patients revealed a success rate of 83.5 % after combined LIFT approach. The use of bone marrow aspirate concentrate (BMAC) in surgery is not entirely new as it has been widely used in the treatment of bone defects, mandibular reconstruction, maxillary sinus augmentation and in critical limb ischemia. A previous study concluded that the use of BMAC to augment external anal sphincter repair strengthens wound healing by transferring cells responsible for healing directly to the site of repair. The current study aimed to assess the outcome of local injection of bone marrow mononuclear cells (BM-MNCs) in conjunction with LIFT as compared to LIFT alone in regards to healing rate, time to healing, and ultimate success rate.
