[Multiple jejunal strictures caused by gastric heterotopia].

A case of gastric heterotopia was discovered incidentally on a jejunal resection specimen in a 42-year-old patient operated for Koenig's syndrome present for 10 years. This anomaly was responsible for seven chronic ulcers with strictures at multiple levels. Gastric heterotopia, especially in the jejunum, is a rare anomaly, except in intestinal duplications and Meckel's diverticulum. The various complications are a direct result of the activity of the gastric glands: hemorrhage, Helicobacter pylori enteritis, perforation, chronic ulcer and obstructive syndrome; malignant adenocarcinomatous degeneration has also been reported.
