title: [Duplication cyst of the stomach antrum as the cause of an acute gastric emptying disorder in an adult].
abstract: METHODS
  A 35-year old woman without previous history of gastrointestinal complaints developed increasing upper abdominal pain with nausea and postprandial vomiting over 2 days during which she had been unable to take any food. She had no fever; her general physical condition was slightly reduced. While her abdomen felt soft on palpation, she had epigastric pain on pressure but no resistance to palpation.
  
  
  METHODS
  Blood picture and routine laboratory tests were unremarkable. Plain film of the abdomen demonstrated marked gastric retention. Abdominal ultrasound showed an invagination in the gastric antrum suggesting a layering phenomenon. Gastroscopy revealed a submucosal tumour-like lesion with central ulceration which obstructed gastric exit.
  
  
  METHODS
  After conclusion of the diagnostic tests on the first hospital day partial gastric resection (Billroth I) was performed as, in the absence of any surrounding reaction, a leiomyoma had been suspected. The further course was without complication and she was discharged on the 13th hospital day. The surgical specimen revealed a duplication cyst of the gastric antrum.
  
  
  CONCLUSIONS
  (Endo)sonography, computed tomography and endoscopy make it possible to diagnose duplication cyst, as long as it is included in the differential diagnosis of acute abdomen in an adult. Emergency resection of the cyst is indicated because of the acute nature of the symptoms. But even in less urgent cases or as an incidental finding it is the treatment of choice.
