Chronic abdominal pain with a rare cause

: The authors use a case report of a female patient with chronic abdominal pain progressing postprandially as an example to demonstrate the complexity of the diagnostic process in patients with these complaints, as well as a surprising peroperative finding in which a small neuroendocrine tumour of the small intestine was the cause of the difficulties. The ensuing discussion also deals with other possible causes of chronic abdominal pain associated with eating disorders.
