Active clinical trials for "Gastrointestinal Diseases"

The purpose of this interventional study is to test and compare the effectiveness of two elimination diets-the 1-food elimination diet (1FED, milk only) and the 6-food elimination diet (6FED, milk, egg, wheat, soy, tree nut/peanuts, and fish/shellfish). The study will also test the effectiveness of swallowed glucocorticoid therapy in some of the study participants for whom diet therapy was not effective.

Upper gastrointestinal endoscopy, like many other diagnostic and therapeutic procedures, may be associated with discomfort. Although upper endoscopy is usually of shorter duration and better tolerated by patients, most trials investigating the influence of analgesia and sedation have been performed on patients undergoing this procedure. Some patients may tolerate colonoscopy without sedation, but various techniques are used to limit discomfort and pain. Selection and dosing of sedatives depends on the patient's emotional state, the intensity of pain during examination, foreseeable technical difficulties, the endoscopist's experience, the presence or absence of anesthesia personnel, and hospital-specific procedures. Conscious sedation is a popular technique for colonoscopy and upper gastrointestinal endoscopy. The combination of an opioid and a benzodiazepine is known to provide good analgesic and sedative conditions during endoscopy. This combination of opioid and benzodiazepine, however, also increases the risk of respiratory depression. Therefore, pharmacologic agents which may provide adequate sedation without respiratory depression are of great interest to clinicians. Dexmedetomidine is a highly selective α2-adrenoceptor agonist with sedative and analgesic effects. Compared with clonidine, it is more selective for the α 2 adrenoceptor and acts as a full agonist in most pharmacologic test models. Potentially desirable properties include decreased requirements for other anesthetics and analgesics, a diminished sympathetic response to stress and the potential for cardioprotective effects against myocardial ischemia. When compared with conventional sedatives such as opioids or benzodiazepines, its lack of respiration depression is a distinct advantage. Previous studies using dexmedetomidine for sedation has been promising with maintenance of respiratory function. Patients are readily arousable. With intravenous slow bolus administration, there is a minimal increase in blood pressure initially, followed by a slight decrease in blood pressure. Lower dose ranges, avoidance of rapid bolus injection, and a slow rate of administration tend to decrease these circulatory side effects. Many clinical studies have shown that it can be well and safely used intravenously, intramuscularly and transdermally. Although not an officially technique, there are also reports of intranasal administration resulting in fairly predictable onset in both adults and children.

Evaluation of the effect of hepatic impairment on the pharmacokinetics of ulimorelin after a single intravenous (IV) dose in order to identify potential patients at risks in terms of severity of hepatic dysfunction and to determine whether their dosage should be adjusted.

The primary objective of this study was to provide daily information on the performance safety of the Ped3CB in practical therapeutic use in pediatric patients.

Purpose: We are proposing to examine, via open label trial, the use of Seroquel® for patients with moderate to severe functional bowel symptoms who are not receiving adequate relief from their symptoms on their present regimen of SNRI or TCA antidepressant agents. Participants: Primary eligibility will be determined of patients at The UNC Center for Functional GI & Motility Disorders Clinic who score in the moderate to severe range on the Functional Bowel Disorders Severity Index (FBDSI ≥ 37) who have failed or have incomplete treatment responses of medications including at least one prior trial of antidepressant medication. Procedures (methods): We will monitor several patient and symptom related outcomes, as well as evaluate health related quality of life, psychological distress and related psychosocial measures to determine if the addition of Seroquel® over and above the use of an antidepressant improves clinical response based on an adequate relief measure as well as selected secondary outcomes. We will also determine when treatment benefit is related to effects on pain, the associated psychological co-morbidities seen in this population, or both factors.

The purpose is to test a coated polyglycolic acid multifilament suture in gastrointestinal surgery as part of a controlled randomized single blinded parallel group trial. The applicability and safety of the strand material used in two suture techniques (2-layer suture technique vs. 1-layer running) are to be tested on the basis of handling characteristics, the operative time consumed for the construction of the 1st anastomosis, the average time of the hospital duration for both patient groups, and the frequency of postoperative complications after discharge, 1 month and a maximum of 3-4 months. The used suture units are counted and the length of sutures determined which will be an indirect measurement of the costs of suture material for the two techniques.

Primary: - To demonstrate the superiority of Moviprep® versus Colopeg® in gut cleansing prior to colonoscopy. Secondary: To assess the safety of Moviprep® versus Colopeg®. To assess acceptability of Moviprep® versus Colopeg®.

The purpose of this study is to determine where amitriptyline is effective in the treatment of functional abdominal pain in children.

The purpose of this study is to determine whether the early identification and more precise intervention of operating room (OR) patient fluid administration optimization using arterial pressure-based cardiac output (APCO) yields comparable patient outcome as fluid administration optimization using a global standard care method.

The purpose of this study is to determine whether Omegaven is effective in the treatment of parenteral nutrition associated liver disease (PNALD).
