title: Gastric outlet obstruction caused by microperforation of Helicobacter pylori-related antral ulcer.
abstract: We report a Helicobacter pylori-related antral gastric ulcer that continued to cause symptoms despite H. pylori eradication. The patient had progressive gastric outlet obstruction, raising the possibility of a malignancy. On exploratory laparotomy, he was found to have a large inflammatory mass surrounding a contained microperforation.
