Active clinical trials for "Abdominal Pain"

The primary objective is to obtain stool samples from pre-therapy subjects already undergoing evaluation for an H. pylori infection by upper esophagogastroduodenoscopy (EGD) and gastric biopsy.

Hypothesis: Endosonography (EUS) in a single setting is equivalent to the standard algorithm combining abdominal sonography, gastroscopy, endosonography in patients with acute right side abdominal pain. Patients with acute right side abdominal pain will be randomized in one of two groups. In each group all examinations (sonography, gastroscopy, endosonography) will be performed. The study group only defines the order of the examinations. Abdominal sonography will always be performed before endoscopic procedures. In group 1, gastroscopy is first followed by endosonography. In group 2 endosonography is first followed by gastroscopy. Two physicians will review all results of all examinations, patient charts as well as a follow up visit and establish a clinical diagnosis. Yield of the clinical diagnosis by EUS results alone will be compared to the yield by combined results of sonography, EGD and EUS.

Colonic diverticulitis is a common clinical condition in patients presenting to the Emergency Department (ED) with abdominal pain. The diagnosis and staging of patients with suspected acute diverticulitis is often made by CT imaging with intravenous contrast, which involves radiation exposure, is expensive and has contraindications. The aim of this study is to evaluate the diagnostic accuracy and role of bedside abdominal US for the diagnosis of acute diverticulitis

The evaluation of patients with abdominal pain is a challenge for the emergency physician and the selection of patients for second-level radiological examinations or endoscopic procedures is not always easy to perform. Faecal calprotectin could be a useful diagnostic marker to distinguish between "organic" or "functional" form and its determination could be helpful to select patients for further examinations, in the context of emergency setting.

This study is a feasibility study. Patients with acute abdominal pain who are planning to undergo a diagnostic laparoscopy are asked to participate in the study. The aim of the study is to evaluate if transgastric peritoneoscopy is feasible.

The study is trying to prove that the history and physical exam (H&P) in the emergency department is the most important tool in exam of patients. The investigator is attempting to correlate the time of the H&P of residents and attendings to the accuracy of diagnosis.

Recurrent abdominal pain (RAP) is a common complaint in childhood. Identification of the processes that maintain illness is important. The purpose of this study is to get more knowledge about characteristics of children with recurrent abdominal pain and their parents, and about the course of their pain. These results may be important to identify children who need treatment.

Randomised controlled trial comparing standard outpatient clinic treatment with multi-disciplinary clinic treatment for functional gastrointestinal disorders. Patients will be followed up to end of clinic treatment and 12 months beyond the end of treatment. Symptoms, quality of life, costs to the healthcare system and psychological outcomes will be assessed.

The investigators aim to evaluate in a retrospective study the performance of the Swiss Emergency Triage Scale to identify at the door of the Emergency Department patients requiring emergent intervention.
