Phlegmonous gastritis occurs in

Phlegmonous gastritis( due to reflux of acid) is an uncommon form of gastritis caused by numerous bacterial agents, including streptococci, staphylococci, Proteus species, Clostridium species, and Escherichia coli. Phlegmonous gastritis usually occurs in individuals who are debilitated. It is associated with a recent large intake of alcohol, a concomitant upper respiratory tract infection, and AIDS. Phlegmonous means a diffuse spreading inflammation of or within the connective tissue. In the stomach, it implies infection of the deeper layers of the stomach (submucosa and muscularis). As a result, purulent bacterial infection may lead to gangrene. Phlegmonous gastritis is rare. The clinical diagnosis is usually established in the operating room, as these patients present with an acute abdominal emergency requiring immediate surgical exploration. Without appropriate therapy, it can progress to peritonitis and death. Ref Davidson edition23rd pg802
