Abdominal pain and mass caused by subserosal eosinophilic enteritis

Abstract Eosinophilic gastroenteritis (EGE) causes acute abdomen, which is not diagnosed preoperatively and sometimes requires emergency surgery. Here we report a case of EGE, in which laparoscopy was performed to reveal the cause of recurrent abdominal pain, and a mass lesion was detected. Moreover, we finally diagnosed subserosal layer type of EGE based on the pathological results.
