Filter by:Anal sphincter preserving operations are now commonplace for both cancer and non-cancerous rectal diseases. However, this has not always been the case and this development has been facilitated by the invention of circular stapling instruments, which allow the bowel to be reconnected to the anal sphincters, where it would almost be impossible to do so manually. Nevertheless, some patients still require a permanent ostomy, as even with stapling devices ultra low joins of the bowel and sphincter muscles cannot always be performed by a conventional surgery. Therefore, a variety of alternative techniques have been proposed to avoid a permanent ostomy, but these have not become widespread due to the technical difficulty in performing them, their failure to completely eradicate rectal disease, and the damage they inflict upon the anal sphincters resulting in poor bowel function after surgery. The ideal ultra low sphincter preserving operation should remove the rectal disease entirely, allow the small or large bowel to be safely joined to the anal sphincters under direct vision, and retain the sphincter mechanism in its entirety. We propose such a technique that we term the APPEAR procedure, which approaches the lower third of the rectum via an incision between the scrotum or vagina, and the anal sphincters. This procedure preserves sphincter integrity, and allows either a stapled or manual join of the bowel to the sphincter mechanism, under direct vision. This trial is being conducted as a pilot study, with the procedure only offered to patients for whom a conventional sphincter saving procedure was technically impossible, or contraindicated.
In patients with acute myelogenous leukemia (AML), a high proportion will suffer from inflammation of the large bowel (colitis) during their intensive treatment. As there is no standard treatment available for this potentially lifethreatening condition, the investigators focus on the role of parenteral nutrition which these patients inevitably require. Preclinical and clinical data have shown strong anti-inflammatory properties of fish oil preparations containing poly-unsaturated omega3 fatty acids (PUFA) as opposed to other lipid fractions. There may be a therapeutic benefit of adding omega3 PUFA to standard nutrition in patients with chemotherapy-induced colitis. In this small phase II study, the investigators address the effectiveness of this approach to reduce the incidence and severity of colitis in AML patients.
A prototype colonoscope with an extra passively bending distal section has been developed by Olympus Japan (ref. publications). The present study (2006-2007) is testing refinements of this function.
This study will determine if medical treatment of colitis (inflammation of the colon resulting in loose bowel movements, rectal bleeding, and belly pain) that is used for other colitis conditions, such as Crohn's disease and ulcerative colitis, is safe and effective for treating colitis in patients with Hermansky-Pudlak syndrome (HPS). HPS is a hereditary disorder that causes albinism, visual impairment, and abnormal bleeding. Some patients also develop colitis, pulmonary fibrosis, and kidney disease. Patients with HPS and colitis who are 18 years of age or older may be eligible for this study. Participants receive treatment for their colitis symptoms with one or more of several study drugs, which include mesalamine (5-ASA), corticosteroids, infliximab and 6-mercaptopurine, adalimumab and tacrolimus. The drugs are added to the treatment plan one at a time to find the combination that works best for the individual patient. Patients who respond to one or more of the medications may continue treatment with that same combination for up to 6 months. Regular clinic visits are scheduled for blood tests, symptoms ratings questionnaires and periodic physical examinations and colonoscopies to measure the response to treatment and evaluate any side effects.
All of us have millions of bacteria living in our gut. These bacteria are very important to our health providing us with protection against infections of the gut, allowing us to gain extra nutritional value from food we eat and helping our immune system. Changes in the balance of these many bacteria can make us vulnerable to infections both from within and from outside the gut. Certain bacteria may also be directly associated with some diseases of the gut. Research by doctors and scientists into relationships between the bacteria normally found in our gut and certain diseases of the gut is helping to develop food supplements and other therapies to treat these diseases. This study involves research into the usefulness and safety of two probiotic products in maintaining remission in Crohn's disease and ulcerative colitis. Approximately 360 patients with Crohn's disease and ulcerative colitis from Ireland, Finland and Spain will be involved in the study. The yoghurts used in this study contain either Lactobacillus salivarius subsp. salivarius or Bifidobacterium infantis.
The purpose of this study is to compare the efficacy in maintaining remission of ulcerative colitis between a once daily (QD) Asacol regimen and a divided, twice daily (BID) Asacol dosing regimen.
The aim of this study was to investigate the safety and efficacy of SPD476 2.4 g/day given twice daily ([BID] ie 1.2 g/day BID) and SPD476 4.8g/day given QD compared to placebo in subjects with acute, mild to moderate ulcerative colitis.
To compare the efficacy of visilizumab at 5 mcg/kg/day administered intravenously (IV) on Days 1 and 2 to placebo in subjects with IVSR-UC.
- PHASE: II - TYPE OF STUDY : With direct benefit - DESCRIPTIVE: Multicenter, randomized, double-blind study - INCLUSION CRITERIA: Steroid-dependent ulcerative colitis - OBJECTIVES: To show superiority of methotrexate vs placebo in inducing steroid-free remission in steroid-dependent ulcerative colitis - STUDY TREATMENTS: Methotrexate 1 intramuscular injection (25 mg) per week Placebo 1 intramuscular injection per week - NUMBERS OF PATIENTS: 55 patients in each group, i.e. a total of 110 patients - INCLUSION PERIOD: 24 months - STUDY DURATION: 36 months - EVALUATION CRITERIA: Remission without steroids, immunosuppressives and without colectomy at 16 weeks of treatment.
Ulcerative colitis is a systemic disease we assume that extra intestinal involvement as we describein our study( Fireman Z, Osipov A, Kivity S, Kopelman Y, Sternberg A Fireman E: Assessment of pulmonary involvement in Crohn’s disease by induced sputum. Am J Gastroenterol 2000;95(30):730-734. )
