Filter by:The purpose of this study is to show that the surgical site in the bowel wall can be sewn closed in the colon or intestine, with a new sewing device after removal of a benign polyp according to standard of care.
The study aims to evaluate the long-term efficacy and prognosis of hysteroscopic resection and coagulation of the base of endometrial polyps with focal atypia in fertile women.
The purpose of this study is to find out if guided fluid administration with the esophageal monitor is superior to standard fluid administration and whether use of the hetastarch or lactated ringers offers different benefits with respect to length of stay in the hospital after hand-assisted colorectal surgery.
The purpose of this study is to evaluate the safety and efficacy of a new treatment for nasal polyps as compared to placebo (an inactive substance). The treatment involved is mint tea high in rosmarinic acid. Rosmarinic acid is a polyphenol, or a chemical substance found in certain plants such as oregano, rosemary, and the mints. It is the active ingredient in spearmint. The placebo used in this study will be mint tea low in rosmarininc acid. In this trial the amount of rosmarinic acid in the high rosmarinic acid tea, or study tea, will be 150mg. The placebo, or low rosmarinic acid tea, will contain 10mg of rosmarinic acid.
The purpose of this study is to determine the effect of two doses purified EPA (an omega-3 fatty acid), on apoptosis (natural cell death) and cell proliferation (formation of new cells) in the lining of the colon for patients with a history of colonic polyps.
The study team has developed a set of biomarkers of risk for colon cancer; this study tests 1) whether or not calcium and/or vitamin D supplementation can favorably affect these biomarkers in persons who are at higher than average risk for colon cancer (ie, have already undergone the removal of colon growths, called adenomatous polyps, which are known to be precursors to developing colon cancer), and 2) whether effects on the biomarkers predict who will get new colon polyps or not.
The purpose of this study is to evaluate the safety and efficacy of Nasonex® (Mometasone Furoate Nasal Spray(MFNS)) in the treatment of nasal polyps in pediatric subjects between the ages of 6 and less than 18 years old. Safety will be the primary focus of this study.
The primary objective of the Poly Prevention Trial (PPT) is to determine whether a low fat, high fiber, high vegetable and fruit eating plan will decrease the recurrence of adenomatous polyps of the large bowel. Secondary objectives of the PPT include 1) evaluating the effectiveness of the intervention program with respect to participant achievement of dietary goals; 2) examining the relation of dietary change and biochemical markers in blood; and 3) assessing the impact of the intervention on quality of life indicators.
The purpose of this study is to determine whether Barium or BariumFerumoxsil is better for fecal tagging in MR colonography. Patients referred to colonoscopy are offered MR colonography before colonoscopy. Two days before colonography, patients ingest either a contrast agent A (200 ml Barium sulphate solution 1g/ml)) four times a day or a 200 ml contrast agent B (Barium sulfate(25%) and Ferumoxil(75%)) four times a day, which will render fecal masses "invisible" on the following MR colonography. The patients are randomised to either contrast agent A or B. The examinations are evaluated by two independent blinded readers, who will rate the tagging quality of the contrast agents. The quality of tagging will be rated by a Visual Analog Scale (VAS) and Relative contrast (ReCon = Iwall - Ilumen/ Iwall + Ilumen).
This is a randomized controlled trial of aspirin and/or folate supplementation for the prevention of the recurrence of neoplastic polyps (adenomas) of the large bowel.
