[Acute gastric dilatation with superior mesenteric artery syndrome in a young girl with anorexia nervosa].

BACKGROUND
Acute gastric dilatation is a rare complication of anorexia nervosa which may be fatal in case of gastric perforation. Superior mesenteric artery syndrome may be associated with gastric dilatation.


CASE REPORT
A 14 year-old girl was admitted suffering from severe anorexia nervosa. Shortly after admission, she complained of abdominal pain related to a bulimic episode a few days before, followed by nausea and vomiting. Distended abdomen and tachycardia suggested acute small-bowel obstruction. A diagnosis of acute gastric dilatation with superior mesenteric artery syndrome was suspected on X-ray examination and confirmed by esophagogastrography after gastric evacuation. The patient improved rapidly under total parenteral nutrition. Upper gastrointestinal study repeated 10 days later showed normal stomach.


CONCLUSIONS
Small-bowel obstruction in anorexia nervosa first evokes acute gastric dilatation, and a perforation has to be ruled out by esophagogastrography. Association with superior mesenteric artery syndrome is possible; it does not necessarily lead to surgery.
