Gangrene of the stomach is a rare, often fatal disease which may be due to vascular, chemical, mechanical, or infectious etiologies. We report a case of gastric gangrene due to acute necrotizing gastritis in a 58 -year-old male. Review of the literature on suppurative gastritis emphasizes the rarity and high morbidity of acute necrotizing gastritis. The patient reported on in this study, however, survived after sleeve gastrectomy and antibiotic therapy. It is our opinion that surgical removal of involved non viable gastric tissue with healthy margin is inevitable for successful treatment.
