[Stomach duplications apropos of a case revealed by digestive hemorrhage. Value of ultrasonic endoscopy. Review of the literature].

Double stomach is a relatively rare inborn malformation. Manifestations are usually observed during the neonatal period or in early childhood. In adults, complications usually lead to diagnosis. Echographically and endoscopically, the malformation takes on the aspect of a tumour of the gastric mesenchyme. Echo-endoscopy is required for diagnosis. Surgery is the only treatment with or without exeresis of the gastric collar surrounding peripheral often pediculated lesions. Laparoscopic control may be helpful. Other procedures may be adapted on a case by case basis. Prognosis depends on associated malformations.
