Endosonography For Right Side Acute Intestinal Mal-Symptoms (EFRAIM- Study)
Endosonography For Right Side Acute Intestinal Mal-Symptoms (EFRAIM- Study)
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.
