1. Chemotherapy Alone or Chemotherapy Plus Radiation Therapy in Treating Patients with Locally Advanced Rectal Cancer Undergoing Surgery

   Mankato, Minn.

   The standard treatment for locally advanced rectal cancer involves chemotherapy and radiation, known as 5FUCMT, (the chemotherapy drugs 5-fluorouracil/capecitabine and radiation therapy) prior to surgery. Although radiation therapy to the pelvis has been a standard and important part of treatment for rectal cancer and has been shown to decrease the risk of the cancer coming back in the same area in the pelvis, some patients experience undesirable side effects from the radiation and there have been important advances in chemotherapy, surgery, and radiation which may be of benefit. The purpose of this study is to compare the effects, both good and bad, of the standard treatment of chemotherapy and radiation to chemotherapy using a combination regimen known as FOLFOX, (the drugs 5-fluorouracil (5-FU), oxaliplatin and leucovorin) and selective use of the standard treatment, depending on response to the FOLFOX. The drugs in the FOLFOX regimen are all FDA (Food and Drug Administration) approved and have been used routinely to treat patients with advanced colorectal cancer.

2. A Study to Assess Outcomes of Patients Undergoing Treatment of Fistula-in-ano Utilizing a Radially Emitting Diode Laser Fiber

   Rochester, Minn.

   The purpose of this study is to assess short and long term outcomes of patients undergoing treatment of fistula in ano utilizing a radially emitting diode laser fiber.

3. A Clinical Study Comparing Standard Anastomosis Closure Technique to Standard Closure Techniques Plus Sylys® Surgical Sealant

   Jacksonville, Fla., Rochester, Minn.

   The Cohera Sylys® Surgical Sealant study is a prospective, randomized, controlled, multicenter technical feasibility clinical study comparing standard anastomosis closure technique (Control) to standard closure techniques plus Sylys® Surgical Sealant (Test) during colorectal and ileorectal anastomosis procedures.

4. Study to Evaluate the Safety and Efficacy of Two Drug Regimens in Subjects with Moderate to Severe Ulcerative Colitis

   Rochester, Minn.

   To evaluate safety and efficacy of two dosing regimens in achieving clinical remission at Week 8 in subjects with moderately to severely active Ulcerative Colitis.

5. Stem Cell Coated Fistula Plug in Patients With Crohn's RVF

   Rochester, Minn., Rochester, Minn.

   The purpose of this study is to determine the safety of using an autologous mesenchymal stromal cell (MSC) coated fistula plug in people with rectovaginal fistulizing Crohn's disease. Autologous means that these cells that coat the plug come from you. You will be in this study for two years. There is potential to continue to monitor your progress with lifelong regular visits as part of your standard of care. All study visits take place at Mayo Clinic and Rochester, MN. The study visit schedule is as follows: Visit 1 (Week -6) - Screening visit: exam under anesthesia and surgery to assess eligibility of fistula tract, take fat biopsy, if eligible, and fecal diversion. Visit 2 (Week 0; Day 0), exam under anesthesia for stem cell coated fistula plug placement Visit 3 (Week 0; Day 1) Visit 4 (Week 2; Month 1) Visit 5 (Week 4; Month 1) Visit 6 (Week 8; Month 2) Visit 7 (Week 12; Month 3) Visit 8 (Week 24; Month 6) Visit 9 (Week 52; Month 12). Visit 10 (Week 104, Month 24)

6. Mesenteric Sparing for the Prevention of Recurrent Crohn's Disease

   Rochester, Minn.

   The purpose of this study is to determine if taking an increased sampling of mesentery (fatty tissue next to the intestine) and lymph nodes at the time of the subject's ileocolic resection prevents a 4-6 month recurrence of Crohn's disease at the site of the new connection.

7. The Affect of Low-Volume Bowel Preparation for Hospitalized Patients Colonoscopies

   Scottsdale/Phoenix, Ariz.

   The purpose of this study is to compare the efficacy of a low-volume bowel preparation versus a high-volume bowel preparation for bowel cleansing on hospitalized patients undergoing colonoscopies.

8. Chemotherapy Alone or Chemotherapy Plus Radiation Therapy in Treating Patients with Locally Advanced Rectal Cancer Undergoing Surgery

   Scottsdale/Phoenix, Ariz., Rochester, Minn., Scottsdale/Phoenix, Ariz., Rochester, Minn.

   The standard treatment for locally advanced rectal cancer involves chemotherapy and radiation, known as 5FUCMT, (the chemotherapy drugs 5-fluorouracil/capecitabine and radiation therapy) prior to surgery.

The drugs in the FOLFOX regimen are all FDA (Food and Drug Administration) approved and have been used routinely to treat patients with advanced colorectal cancer.

9. Characterization of Crohn’s Disease at a Cellular Level

   Rochester, Minn.

   The purpose of this study is to define and genotype the immunomodulatory properties of mesenchymal stem cells (MSCs) from Crohn’s disease subjects as compared to healthy/control subjects (diverticulitis, ulcerative colitis or subjects with perianal disease including hemorrhoids, cryptoglandular fistula, anal fissure, anal skin tags) or colon and rectal subjects.

10. Hyperbaric Oxygen for Ulcerative Colitis

    Rochester, Minn.

    The investigators aim to prospectively study the feasibility and clinical impact of hyperbaric oxygen therapy in acute hospitalized moderate to severe ulcerative colitis flares as an adjunct to standard medical treatment. Specifically, we will investigate the impact of hyperbaric oxygen therapy on clinical response/remission and serum and mucosal inflammatory markers. The investigators expect that hyperbaric oxygen therapy will improve patient responsiveness to steroids and avoid progression to second line therapy during hospitalization.
