Abstract

Intestinal malrotation is a rare congenital disorder that consists of incomplete rotation or non-rotation of the mid-primitive intestine during embryonic development. It tends to manifest itself in the first months or years of life, and in adulthood its manifestation is rare. We present the clinical case of a 25-year-old woman with a history of acute abdominal pain predominantly in the right iliac fossa, vomiting and anorexia. Intraoperatively, the clinical suspicion of acute appendicitis was confirmed, however in an atypical location associated with intestinal malrotation, having led to the need to adapt the laparoscopic approach.
