Patient have underwent laparoscopic RYGB surgery (the standard procedure with closing of mesenteric openings) at least half a year ago;
Patient has abdominal pain at least three days in a row
Patient is highly suspected for internal herniation judged by the surgeon and based on weight loss and pain (location of the pain, the intervals between pain, the relation to food intake).
Age < 18 years;
Patient is incompetent to decide;
Patient is in emergency setting and requires imminent surgery;
Other abdominal pathology or prior large abdominal surgery;

- Primary Outcome Measures
Name Time Method <p>Primary study endpoints are the assessments of the arterial abdominal angiogram<br /><br>and mesenteric arterial mapping in relation to the outcome of the diagnostic<br /><br>laparoscopic surgery.</p><br>
- Secondary Outcome Measures
Name Time Method <p>Secondary study parameters are the assessments of the conventional CT abdomen,<br /><br>the CT angiogram and the mesenteric arterial mapping, the comparison of these<br /><br>images and the comparison of these images to the surgical outcome. The<br /><br>sensitivity and specificity of both CT scans to diagnose an internal herniation<br /><br>will be calculated</p><br>
